Analyzing Linear Accelerators and Their Major Components

Linear accelerators are widely used for the treatment of cancer using high radio-frequency electromagnetic waves to speed up electrons to increased energy in a linear path inside of an accelerator waveguide. The frequency is medical LINACs is around 3 billion Hertz. As the most common form of external beam radiation treatment after a cancer diagnosis it is crucial for end users to have a basic understanding of what a LINAC is. As well as how the major components within LINAC systems work in conjunction with one another to produce radiation treatment.

Consider how a microwave oven works. This is in the most basic sense how a linear accelerator operates. A LINAC uses microwave technology to accelerate charged particles within a waveguide, tube like structure. These electrons then strike a metal target producing photons. It is these photons that are focused on the cancerous tumor. This radiation is delivered in the shape of the tumor to avoid contact with healthy tissues with the use of a variety of positioning devices. Now that we have a general understanding of the linear accelerator lets take a look into the major components that allow LINAC systems to operate as we know them to as of today.

Drive Stand:

A drive stand is a rather large cabinet, usually rectangular in shape, that secures the LINAC machine to the floor of the treatment room that houses the gantry.

Gantry:

The gantry is a moveable frame of the LINAC that is located in the drive stand and rotates on a horizontal axis. It helps direct the photon beams directly into the patient’s tumor. The gantry rotates 360 degrees on its axis. There are three components that are found within the gantry: the electron gun, accelerator structure, and treatment head.

Klystron:

The klystron is a major component that is located within the drive stand that delivers the microwave energy that is used to accelerate the electrons through amplified RF electromagnetic waves.

Accelerator Guide:

The energy from the klystron moves to the accelerator structure to speed up electrons.

Treatment Head:

The treatment head of a LINAC encases the components that shape the radiation to the specific size of the cancerous tumor. This can include: bending magnets, primary collimator, beam flattening filter, wedges, blocks, and compensators.

Cooling System:

The water cooling system in a linear accelerator is located within the drive stand and gantry to regulate the temperature in the space.

In our next installment we will look in greater detail to the treatment head of a LINAC system and the variety of components housed within that help shape radiation beams into the shape of different cancerous tumors.

Advantages of Purchasing Refurbished Radiation Oncology Equipment

Purchasing refurbished medical equipment is never a bad idea. Despite the allure of buying new radiation oncology equipment, purchasing a refurbished linear accelerator for your practice might be a better choice. There is a lot to consider when you’re getting ready to purchase radiation oncology equipment for your practice like space, budget, and personnel impacts. Before you purchase all-new equipment consider just a few of the advantages of buying refurbished medical equipment below:

Costs

The biggest advantage when buying refurbished linear accelerator equipment is the cost. Buying new can really blow your entire budget, but used ones can actually make your budget stretch more, allowing you to do other things for your practice. By going for the cheaper option, you still get a quality piece of equipment at a fraction of the cost of what you would pay for a new model.

Buy More Equipment

If you’d like to offer more services to your patients, you can easily buy two or more pieces of radiation oncology equipment for your practice instead of just buying one new linear accelerator. This allows you to treat more patients for the price of what you would have spent if you only bought one machine. This way your practice can offer more appointments, getting more patients on the books and increasing your ROI.

Use That Money Elsewhere

For the price you’ll buy for a refurbished linear accelerator, you can use that extra money to do other things that will benefit your practice. You can use that money to redesign the patient waiting room area or hire more staff for better customer service. If buying a used machine is just as good as a new one and will get the job done, why not use that extra money for good somewhere else? This way you’ll be able to grow your practice and expand its success.

New Equipment For Half The Price

Refurbished pieces have been fixed by professionals to function like new, so you’ll get a practically brand-new linear accelerator affordably! Every refurbished piece is seen by a skilled medical technician before getting discharged back into service, so everything that needed fixing was fixed and you get something practically new without the new price tag.

As with any piece of medical equipment new or refurbished, there are times when equipment fails or needs maintenance. For these instances there are professionals offering service and parts to repair and maintain linear accelerators. Companies such as Radparts offer a huge selection of linear accelerator parts and innovative replacement and repair solutions that in many cases can save you up to 50% or more on your linear accelerator parts costs.

Discover Why You Need Scheduled Repairs to LINAC Systems Prevent Unnecessary Downtime

To ensure that medical equipment such as LINAC systems and CT Scanners are fully functional and effective at all times, while preventing unnecessary downtime, scheduled maintenance is recommended. Scheduled repairs allow for treatment to be scheduled around replacing worn parts and preventative maintenance. Medical equipment of all varieties, including linear accelerators, is costly and expensive to replace. Facilities should not wait until they are damaged or dysfunctional to create a plan of action. There is a significance cost savings in scheduled repairs and pre-planning for replacement.

What Is Scheduled Maintenance?

Scheduled maintenance is the planned component of repair or replacement that is also referred to as preventative maintenance whereby the system is thoroughly inspected to ensure that all parts are functioning properly. Linear accelerator parts are replaced that are known to wear out when historically known to wear out.

Why Are Scheduled Repairs to LINAC Systems Important?

LINAC systems are incredibly sensitive in terms of handling and maintenance. They need to be kept functional and unnecessary downtime needs to be avoided especially because on-time treatment is imperative. If maintenance is not completed and needed maintenance is avoided damage to some key parts of the LINACS or alter the value of your equipment. Linear accelerators and radiation oncology equipment that is being used in hospitals need to be kept in perfect working order for them to deliver accurate and timely results that guide doctors in the treatment of their patients.

Where to Find Linear Accelerator Parts

A LINAC system is prone to faults, as is all medical equipment, and may require occasional repairs. To ensure that the system stays functional and is effective, you need to find a service company that offers genuine and functional linear accelerator parts and repair services. Working with a company that has a record of offering professional repair services, when they are needed with access to LINAC parts is crucial. Working with highly skilled engineers guarantees you of a highly effective LINAC system.

What’s the Cost for Scheduled LINAC Systems Repairs?

The cost of scheduled linear accelerators repairs will depend on the company that you hire to perform service. Look for a LINAC service company that goes out of their way to ensure timely service, repairs, monitoring, and replacement parts for reasonable. Seek a company with a proven track record that you can rely on.

Repairing LINACS With OEM Replacement Parts

LINAC system is the common name for linear accelerators. Their parts are very complicated, and they are intricately built machines. A direct linear accelerator is a gadget that utilizations high radio-frequency (RF) electromagnetic waves to quicken charged particles for generating high energies in a straight way, inside a tube-like structure called the direct linear accelerator.

The resonating frequency of the medical LINAC is about 3 billion Hertz cycles per second. This is the most widely recognized gadget to treat the tumor with outside pillar radiation. To sum up, the linear accelerating agent is fundamentally a mechanical assembly to accelerate charged subatomic particles, utilized as a part of radiotherapy, and the creation of radionuclides.

What to do when the machine gets broken?

Frequently, the parts for repairing linear accelerator agents, LINAC, are expensive to the point that they come just in case of the genuine sum for purchasing another LINAC. This influences numerous individuals to think about whether it is smarter to simply purchase another machine by and large since alternate parts of the LINAC may separate soon enough and should be supplanted too. Along these lines, as we would like to think, settling radiation machines and LINACs is the better alternative.

Repairing LINACS with OEM replacement parts

Parts for repairing linear accelerator agents may be very costly, however, that is whether you purchase new parts. Rather, you can select the sensible alternative, which is revamping or repairing the broken parts. There are various firms in the market that offer revamping of parts for radiation hardware. The restored parts are frequently returned rapidly, and this productive procedure spares you a large portion of the cash you would spend on another part. Accordingly, it is best to locate a decent overhauling organization for your LINACs.

Linear accelerators are complicated devices. Each one has thousands of parts that work together to send subatomic particles hurtling at incredible speeds toward a target. They can be used in radiation therapy to fight cancer, academic research and more.

It only takes one failing part of the linear accelerator to stop the entire machine. Those broken parts are not just tossed in the trash. Instead, OEM replacement parts often refurbish and repair the parts for future use with the same level of quality as a new part.

In fact, OEM replacement parts repair several hundred LINAC systems a year for clients all over the world and are best to use for replacement parts.

When a client sends any of the OEM manufacturer or service provider a damaged part, they can often get them a replacement within one day. Similarly, they can then take the damaged part and hand it over to the trained technicians to repair for resale. So, don’t wait and use them with confidence for repairing the linear accelerators parts.

Maintaining LINAC Systems with OEM Replacement Parts

Any electrical equipment that is repeatedly used will break down due to several reasons such as improper maintenance or lack thereof. They can also malfunction owing to poor electrical connections, overrunning the machine’s capability, having an untrained individual operate the equipment, including not replacing worn out parts when needed.

The Importance Of LINAC Parts

A linear accelerator (LINAC) is a very complex medical device that delivers high-energy X-rays to treat patients with cancer. Each component within a LINAC system is important, and all of them need to continually undergo rigorous, cleaning, testing, and maintenance to ensure optimal performance.

Linear accelerators Parts are very costly, and most LINAC owners often consider the option of buying a brand-new unit instead of paying for outrageously high repair parts costs, including maintenance and upkeep fees. Even though all LINAC parts have separate but vital functions, they are linked to each other and therefore, need to work in cohesion. Any breakdown of one of the parts can lead to a ripple effect that may render the whole system useless.

Cooling the LINAC Parts

The linear accelerator works by producing high energy particle beams, thus making the cooling system inclined to overheat. Depending on the model, most LINACs use a water cooling system that provides thermal stability to the system and allows the gantry and drive stand to operate at a constant temperature.

Today there are technologically advanced air-cooled chillers for LINAC cooling systems that are would probably cost more to replace a broken system. There are several independent oncology equipment refurbishing companies that have original equipment manufacturer (OEM) LINAC replacement parts, which even though they are also costly, however, once these LINAC parts are replaced, the system can continue to work like new.

The only concern when using such a complex and volatile piece of equipment is to maximize its uptime and minimizing on the overall total cost of ownership. Having said that, LINAC parts are available through the original equipment manufacturer (OEM) online or through a local dealer. The catch-22 is, do you go the economical way, such as scouring the local neighborhood depot to find the cheapest option that will work anyway, or do you stick with the original manufacturer’s LINAC parts?

Purchasing Replacement Parts

While the LINAC parts you find locally will probably serve you for a while until you can afford an OEM, but when it comes to quality, the materials will not be the same as the original. You can end up with a new replacement LINAC part that does not match up in the case of complicated parts and assemblies.

Maintaining LINAC systems with the original equipment manufacturer replacement parts also guarantee warranty coverage on each piece of equipment and in case the system fails, you can file a warranty claim provided the replacement parts that have been used match the manufacturer specifications. Using OEM LINAC parts also ensures the related components are compatible with the system, they are durable, and most importantly, they are reliable.

The Average Lifespan of Linear Accelerator Parts

A linear accelerator, often referred to as a LINAC, is a type of particle accelerator that customizes electrons or high energy x-rays to conform to the shape of a tumor to destroy cancer cells while sparing the life of normal surrounding tissue. It has a variety of built-in features that are designed to ensure a patient receives only the prescribed dose as directed by a physician. However, linear accelerators are made up parts components that could age over time. What is the average lifespan of these parts?

Lifespan Of A Linear Accelerator

Two major determinants of the lifespan of a linear accelerator and indeed any equipment, are usage and maintenance. Although it is reasonable to expect a usage of between 5 to 10 years, maintenance of the accelerator will be critical to just how much you enjoy the equipment. Here we look at the parts of a linear accelerator and their average lifespan depending on usage.

Parts such as Magnetron and iView detector last for about two years with high use, and between 4-6 years with low and moderate use. An x-ray tube lasts for about 18 months upon high use, 3 years when the system is moderately used, and above 4 years when the usage is low. An XVI detector lasts for about 5 years upon high usage, about 7 years when used moderately, and over 10 years when the accelerator usage is low. On the other hand, a Thryratron tube can last up to 3 years when the usage is high and 5 years and above upon low to moderate usage of the accelerator.

Age Vs. Usage

Basically, the average lifespan of each linear accelerator part largely depends on the part and amount of usage. Other parts such as the electron gun would need a replacement after one year on high use, while it can last even above 6 years upon low usage. Environmental factors can also affect the ion chamber of a linear accelerator, high humidity can cause a reduced lifespan. While an average ion chamber will only need a replacement after four years, one in an environment with high humidity will need a replacement after a year.

Replacing Aging Parts

Changing aging parts over time is ideal to avoid causing the equipment any damages. Some companies tend to consider the price of the equipment and the costs involved in changing the parts over time. However, this is never a good yardstick to even maximize profits in the long run as a breakdown of significant parts of the system may be disastrous for the equipment.

Fix or Forget It: Should you Repair That LINAC System or Buy New?

LINAC systems, the common name for linear accelerators, are very complicated and intricately built machines. They are formed by joining together several very small different parts, making it a highly fickle machine. Despite their extreme sensitivity, LINACs are very useful and powerful machines. They are a main component of many essential machines, such as the CT scanner.

Much like the CT scanner, linear accelerators can be used in several other machines related to the health industry. They are thus an integral part in fighting cancer with radiation therapy, while also being used in a large amount of research. However, because of their unbalanced structure, they are highly prone to many mechanical faults. Here is a look at the faults they may face and dealing with them.

Problems LINAC Systems Face

Used to hurl very small radiation particles at very high speeds at designated targets, linear accelerators are built by joining numerous small parts. Each part has its own function in the grand scheme of things and is often linked to adjacent parts. This makes the LINAC a very fickle machine since any faulty part can lead to the entire machine going out of order. Hence, the LINAC is an unsustainable machine that can require very intricate maintenance.

Everyone has heard about radiation equipment and how much intricate and complex it is. LINACs are a major component in radiation equipment. Parts for repairing radiation equipment are always very expensive, and this makes repairing LINACs a huge financial hassle, while also being exhausting. Therefore, the debate about whether to install spare parts or to change the machine entirely holds a lot of weight and is something that many professionals in the health industry constantly talk about.

Fix it or forget it?

Often the parts for repairing linear accelerators (LINAC) are so expensive that they come just in short of the actual amount for buying a new LINAC. This makes many people wonder if it is better to just buy a new machine altogether since the other parts of the LINAC might break down soon enough and need to be replaced as well. Although there is no definite answer to this query since it has do a lot with the personal beliefs of people, it is always better to use something to the maximum. Therefore, in our opinion, fixing radiation machines and LINACs is the better option.

Refurbishing/ Repairing

Parts for repairing linear accelerators might be highly expensive, but that is if you buy new parts. Instead, you can opt for the sensible option, which is refurbishing or repairing the broken parts. There are a number of firms in the market that offer refurbishing of parts for radiation equipment. The refurbished parts are often returned very quickly, and this efficient process saves you half the money you would spend on a new part. Therefore, it is best to find a good servicing company for your LINACs.

Finding Linear Accelerator Replacement Parts

Whether you have a Varian, Elekta, Philips, Siemens LINAC, you can always find replacement parts, accessories and various linear accelerator components that met OEM specification to get your radiation device working like new.

A linear accelerator is a medical device used for external beam radiation treatments for patients with cancer through a uniform dose of high-speed electrons and high-energy x-rays that are directed to the affected area of the patients’ tumor to destroy the cancer cells without damaging any healthy tissue.

Importance Of Safety

Patient safety, in this case, is very important and the last thing a radiation oncologist needs is a system malfunction or downtime that will impede a treatment session or cause an overdose of the prescribed treatment volume and dosage.

While modern radiation machines have inbuilt checking systems to provide additional safety and there are measures in place to ensure that the linear accelerator is on point and won’t deliver a higher dose than the radiation oncologist prescribed before the start of every treatment session, through no fault of the radiation oncologist, mechanical mishaps do occur.

Services Offered

Along with the aftercare services, upgrades, and repair parts required to keep a linear accelerator working in top condition, professional LINAC engineers offers the most cost-efficient radiation oncology equipment solutions. They include delivery, installation, acceptance testing, commissioning services, warranty, continuing service, and most importantly, linear accelerator components and accessories that are available in stock for immediate delivery.

In addition to equipment testing, quality assurance assistance and data collection, linear accelerator service providers also offer the following services and linear accelerator components:

Disposal of Equipment

Oncology clinics can now benefit from replacement parts for some of the top linear accelerator brand names, and the best part of this whole process is that when the life of a linear accelerator comes to an end, there are disposal services that conform to regulatory requirements. The equipment is professionally removed from the clinic using specialized cranes without damaging its structural integrity. The removal specialists ensure that any disposal of radioactive and hazardous materials from the LINAC is carried out through a licensed disposal company.

Upon request, an oncologist can receive an equipment evaluation and appraisal in the event they want to sell their LINAC or replace it with a newer model. Whatever your radiology need is, they can be met in a timely, professional manner at a competitive fee. Do you need any linear accelerator components, replacement parts, accessories, and repair solutions?

Refurbished Parts are Important in Linear Accelerator Repair

Medical Equipment and Replacement Parts

Linear accelerators are machines that help in the treatment of cancer. These machines have a multitude of components that keep them running efficiently. Sometimes, large pieces of equipment including those found within the radiation oncology department need maintenance involving replacement parts. There are companies devoted to selling, service, and repair new and refurbished LINAK systems and their replacement parts.

Medical facilities can seek out the help of distributors of both OEM and refurbished replacement parts for a variety of manufacturers that produce radiation oncology equipment. No matter what is needed for your radiation equipment facilities have access to them. One of the main purposes of using refurbished replacement parts over OEM parts is that they offer amazing quality and allow medical facilities to accomplish repairs and service at a lower cost.

Radiation Oncology Equipment Repair and Maintenance

For many medical facilities the decision between purchasing new or refurbished parts for maintenance and repairs on large scaled equipment has been met with some indecisiveness. This should however no longer be the case. Linear accelerator parts and components are met with stringent guidelines throughout the reconditioning process. Refurbished linear accelerator and CT scanner parts are suited for both maintenance and repair purposes.

Another major benefit outside of the stringent testing that is done on refurbished linear accelerator parts is the cost savings that facilities will find by purchasing them. When it comes to the cost of refurbished components verse OEM parts, facilities should expect to pay upwards of fifty percent less for reconditioned parts. Just as refurbished linear accelerators are best for new medical companies or facilities working within a strict budget, so are the refurbished parts and components. This can be super beneficial in low budget, non-profit, and veteran facilities.

Refurbished equipment and replacement parts are important because of the certain advantages which only they can offer. There are many reasons that facilities use refurbished parts in the equipment they use. One of the major reasons is that it helps growing practices. LINAC systems that are refurbished free up resources and reduce costs. This is helpful in new center set ups, purchasing additional or backup equipment, and installing new treatment rooms to accommodate more patients for treatment.

Managing Costs

Refurbished components are important in managing expenses. Linear accelerator replacement parts that have been refurbished can help in managing the investment risk of new equipment which can be quite costly. Thus, in times of financial constraint and tight budgets, refurbished equipment and parts can help you save money while growing your facility. Refurbished equipment can also serve as backup equipment for larger facilities giving another option over rescheduling patients when equipment needs to be repaired.

Targeting Cancer with Radiation Treatment Machines

Searching for the right radiation oncology positioning device and quality radiotherapy equipment services can be hard. However, there are certain parameters which you should consider in buying the right positioning devices from the right people without having to compromise on targeting the cancer cells effectively while treating them through the cancer treatment machines.

While it might be thought that the techniques for positioning that were used in the early days can still be used, the fact should be kept in mind that new devices have been developed that have totally eliminated the disadvantages for those early techniques.

What Is a Positioning Device?

Before we could plunge into knowing the parameters which we talked about, let us first know in true terms what really a positioning device is and what it is used for. A positioning device in oncology is anything that can help the oncologist in maintaining a firm and steady position of his or her patient during treatment.

These devices are needed in order to fix the patient in the appropriate position so that there is no radiation leakage to any healthy visceral parts. Too often, positioning errors pose great dangers not for the patient only, but also for the oncologist or radiologist who is carrying out the radiation session. Thus, with the help of positioning devices, these errors can be mitigated to a greater level.

The Need for Positioning Devices

As we have explained the main objective of the immobilization devices, let us see what other needs call for the installation of these devices.

Patient’s Fear

The worries of those who are already battered by lingering cancer that they suffer from could be reduced by using devices that can position them in a better way. Normally, every patient knows the dangers that radiation therapy poses to healthy tissues. In this way, there is a need to assure them of the safety that certain devices can provide.

Daily Set Up Time

The time that is wasted in positioning a patient without the help of immobilization devices can be reduced with the help of them. Since the radiation therapy spans over several days and the radiation has to be targeted on the cancerous cells from different positions, it is indispensable to use positioning devices.

Making a Body Part Rigid

During a radiation therapy session, due to the fear of the patient or any other reason, the body part under treatment can experience flexion. This can put immense pressure on the radiologist or oncologist and thus can reduce the efficiency of the process. So, in order to eliminate any possible chances of the body part, different positioning devices can be used which comply with the structure of that part.

What should you look for immobilization devices?

In order to buy immobilization devices that can target cancer cells effectively, there is a need to pay heed to the following characteristics.

The device should be easy in usage and construction
Patient should not experience any discomfort
The device should be appropriately structured according to the body type of the patient and his or her external contours
It shouldn’t come in the way of the radiation beam
It shouldn’t change shape over time
It should position the patient optimally
The material with which it is made
Its ability to be reused

Considering the above needs and the parameters, you should buy the appropriate radiation oncology positioning device from quality radiotherapy equipment services.
