General Radiotherapy Machines

The most common machine used to distribute external beam radiotherapy treatment is known as a linear accelerator or LINAC for short. LINAC systems generate high energy x-rays that are carefully aimed at the cancerous tumors. This process is done with much care given to direct the rays in a manner that does as little harm as possible to the healthy tissue surrounding the tumor. Linear accelerators are used to treat cancerous tumors on all areas of the body.

Some LINAC systems that are more advanced have the capability to deliver radiation on or near the surface of the skin. In this type of treatment electrons are used in replacement of high energy x-rays.

Newer linear accelerators have the ability to deliver radiation using Intensity Modulated Radiation Therapy, IMRT. These systems use multi-leaf collimators adjust the shape of the radiation beam to match the shape of the tumor. Without these adjustments LINAC systems would only be able to shoot radiation beams in the shape of a square or rectangle.

Radiographers all have different methods that they use to make sure the radiation treatment is targeting the exact location of the cancerous tumor. In its most fundamental form radiation is just a plain x-ray. Most linear accelerators work through digital imaging where the bottom arm of the machine takes an EPI, electronic portal image, or PI, portal image.

The image is compared by radiographers, to images that were generated during the planning process of your treatment as a type of checks and balances before treatment is delivered. The quantity of images that are taken to compare between depends on the departments protocol for imaging. Different types of radiotherapy treatment machines have an On-Board Imager, OBI, that is comprised of a Kv x-ray and detector. Higher quality images are obtained as a verification which allows for another radiotherapy technique known as Image Guided Radiotherapy, IGRT. With IGRT the accuracy of treatment is improved as daily changes are accounted for such as changes in organ location which can in turn reduce unpleasant side effects.

Electrons are generated and speed up to almost as close to the speed of light using electrical fields. The energy continues to increase until it collides with its intended target and then releases the photon energy. These photons enter the patient in an attempt to break down the DNA cells in the cancerous tumor. Healthy cells are most often able to mend themselves where as the cancerous tumors don’t and eventually die.

The Lifespan of a Linear Accelerator Parts

A linear accelerator has a wide range of built-ins that are designed to ensure patients are only given the recommended dose of radiation. The dosage recommended by the physician should never be ignored or changed as each treatment dosage is unique to each patient. Linear accelerators are comprised of several parts and mechanisms that age over time. This article will go over what facilities can expect when it comes to the average lifespan of the parts on LINAC systems, CT scanners, and other radiation oncology devices.

The Lifespan of Linear Accelerator Parts

The lifespan of linear accelerator equipment comes down to two major elements: usage and maintenance. On average medical facilities can expect that large scaled radiation equipment, such as linear accelerators, to last around 5 to 10 years before they begin to break down. Regular maintenance of your LINAC system keeps it running smoother, longer.

Examples of medical equipment lifespans are:

High use parts like Magnetron and iView detectors can last upwards of two to three years and with average use around four to six years.
X-ray tubes with high use last about eighteen months however with low usage can last if four years.
XVI detectors can last up to ten years within linear accelerators that have low usage whereas with high usage XVI parts last around five years.
Thyratron tubes have a lifespan of anywhere between three to five years.

Age and Usage of LINAC Parts

The average life expectancy of most linear accelerator parts depends on the legitimacy of the parts and the amount they are used. There are some parts that need to be replaced yearly with increased use, like the electron gun, however with low usage can last upwards of six years.

Environmental factors cannot be ruled out as it also affects 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.

When to Replace Aging Parts

Replacing aging parts over time is necessary to avoid causing any damages to the equipment. Some corporation has a habit of considering the price of the equipment and the costs involved in changing the parts over time, and as such delayed the immediate replacement of an overdue or overused equipment. But, this is never a good yardstick of profit maximization, in the long run definitely, a breakdown of significant parts of the system may be disastrous to the equipment.

As a Linear Accelerator stays over time and ages, errors can creep in and this will have an adverse effect on the accuracy of the equipment. It is reasonable to expect a good 5 to 10 years of use out of the linear accelerator, but the maintenance also takes its toll on expenses if it stays much longer.

Companies can often get more usage out of a machine and ensure errors are resolved or controlled just by keeping the software up to date and replacing or upgrading linear accelerator parts as at when needed. Most importantly it is advisable to choose a reputable company to replace your LINAC’s aging parts as the wrong equipment can end up creating more damage to the machine instead of improving its performance. Most companies who sell linear accelerators and parts will have service contracts available that offer varying levels of support.

Preventive Maintenance Increases the Lifespan of LINAC Systems

LINAC systems are just one of the methods that facilities use to administer radiotherapy to patients with cancer. The high cost of this technology necessitates that preventive maintenance be routinely undertaken to extend the life span of linear accelerator parts and other radiation oncology equipment. Linear accelerator parts should be serviced to ensure high quality service delivery to patients. This will go a long way in helping cancer patients to access quality treatment.

The main parts of LINAC systems consist of linear accelerator wave guide and the beam defining system. Other parts include: handle control, couch with controls, touch guard and wall panel to hide stand. Being that it is electrical equipment and it’s in continuous use, the systems will breakdown if not cared for properly which will lead to system breakdown. Therefore, preventive maintenance should be regularly done to ensure that the system works effectively and efficiently. A complex system such as linear accelerators and ct scanners depends on electrical connections, once there is poor connection the machine will malfunction. All parts work in cohesion and if one of them is faulty it will affect other parts.

Linear accelerator parts are expensive and the cost of purchasing a new one is prohibitive. Proper preventive maintenance should be carried out from time to time. Most LINAC systems use water cooling because a constant temperature need to be maintained to ensure harmonious operation. However, there is advanced air-cooled chillers for LINAC cooling. This cooling system is expensive but once it is replaced the system works as if it is a new one.

LINAC parts can be procured from the original equipment manufacturer or through local dealers. There are many advantages to buying parts through companies that offer several parts (and services) instead of a more expensive OEM dealer. Often these companies offer less expensive, refurbished options and OEM parts with warranties. If the parts should malfunction within the period of coverage of warranty, they can help. However, one important decision one must make is that whether one should buy refurbished parts or new OEM parts. Refurbished parts are suitable for repairs and maintenance and the cost is lower than buying new ones. This decision is often mostly decided because of your budget however, just know that refurbished parts are just as reliable and as effective so either way you are getting quality parts.

A lot of factors need to be considered when servicing or maintaining LINAC system. One of such considerations is the response time of maintenance company versus original equipment manufacturer. The response time of maintenance companies tend to be quicker than that of the original manufacturer. Therefore, procuring the service of maintenance company will shorten the downtime of the medical equipment. Associated with this is the high level of expertise of engineers working with servicing and maintenance companies.

In most cases, these engineers were trained by original equipment manufacturers hence, the quality of service delivery. Another advantage of servicing and maintenance of linear accelerator parts is that servicing companies have favorable and flexible contract agreement, and this ensure that servicing of equipment is done comprehensively with minimal costs. This contract agreement includes periodical preventive maintenance without extra costs. Routine service and maintenance of LINAC parts are necessary for optimal functioning of the system and it greatly reduces the amount of downtime of the equipment and elongate its lifespan.

Proper Maintenance Keeps Medical Systems Running Smoothly

The manufacturer of all medical equipment routinely establishes a regular maintenance schedule that customers need to be able to accomplish in order to ensure that their system is running properly. These maintenance requirements ensure tests are run to ensure that certain linear accelerator parts are all functioning well. The same is true for oncology equipment parts.

Importance of doing regular proper maintenance

When the equipment you are operating is designed for diagnosing a wide range of serious injuries, illnesses, and diseases it is extremely important that they are working optimally at all times. To be sure that all of your machines are properly maintained you should read all of the documentation that comes with each machine and pays close attention to any section that lists regular or scheduled maintenance.

For some medical facilities this type of maintenance on each piece of equipment requires a special department within the organization. For others it is more cost effective to outsource medical equipment maintenance and repairs to a company that specializes in the repair of medical equipment and parts needed for complex repairs on large scaled equipment such as linear accelerators, CT scanners, and a variety of radiation oncology equipment.

When Is It Time to Replace Your LINAC System Instead of Repairing It?

It is a known fact that linear accelerators, LINAC systems are expensive. Not only is the piece of equipment on a whole costly but also buying the replacement parts for linear accelerators can be quite costly, especially if it is a rush order. Hence, regular maintenance and care must be ensured to enhance its lifespan.

The importance of a LINAC system for a healthcare facility provider that offers cancer treatment is known to one and all. This intelligent system is designed to treat cancerous cells and kill them as part of cancer treatment. Therefore, it is considered to be a vital aspect in the treatment of different type of cancers.

Health experts know that the radiation that emits out of LINAC and other such devices also pose certain health hazards. However, linear accelerators boast of advanced safety measures; hence, these machines are programmed to provide only the required dosage that is required keeping in consideration the condition of the patient.

The problem with LINACS, like other systems, they can start to falter over time. Regular use can lead to damages in different parts of the machine, as a result, it may start showing deteriorate signs or stop working completely. A tough decision to make here is whether to get it repaired or if the equipment needs to be replaced.

The key is to know when to fix or when to replace. When equipment starts to falter on a regular basis, it may be time to look into finding a refurbished LINAC system. However, a system that is just experiencing normal wear and tear should be repaired using linear accelerator replacement parts.

You should consider the replacement option in case a part of the system has faltered or stopped working when it starts to occur on a regular basis. However, in a situation where a single part of the system stops, or something occurs that is normal it is a better option to repair the equipment. These large pieces of medical equipment are meant to withstand time so in many cases repair is the best options.

It really comes down to a number of factors such as downtime from the present equipment. If you are continually experiencing equipment failure that leads to cancelled treatments then you may have to analyze the cost between patient care, cancelled appointments, repair expenses, replacement parts, vs the cost of new equipment.

Service Contracts, Procuring Parts, and Timely Repairs

LINAC service contracts are used in hospitals and clinics on medical equipment and machines that are used in the process of treating cancer patients with radiation therapy. LINAC service contracts are agreements between companies that state services will be performed on medical equipment as necessary for a specific time.

Linear accelerators are available in many medical facilities to be used in the treatment of cancer. This machine allows radiation to conform to the size and shapes of tumors in patients with cancer. This treatment is targeted to the cancerous tumors without affecting healthy tissues that are nearby. Radiation oncology equipment is crucial to treatment. This leads most hospitals and facilities to require regular service and maintenance on medical equipment throughout the radiation department.

Many companies servicing LINAC machines have replacement parts in stock and quick access to regularly needed replacement parts; this ensures that important equipment is serviced and repaired in a timely manner to avoid lengthy downtime. The top five replacement parts kept on hand for linear accelerators maintenance and repair include:

Thyratron

It is used as a high power electrical switch and as a controlled rectifier. It is a gas filled tube and it has the capacity to maintain much greater currents than similar hard-vacuum tubes. IT works according to the phenomenon known Townsend in which the gas becomes ionized on electron multiplication. The failure of thyratron can shut the entire system.

Spare Pendant

Another of the important replacement parts of linear accelerators are spare pendants. They are used to control the motions on a linear accelerator machine. Control of linear set for a patient is limited if a spare pendant is not working.

Hydraulic Actuator

A hydraulic actuator is a cylindrical or fluid motor which converts hydraulic power into mechanical energy used to do the mechanical work in the LINAC machine. It can produce linear, rotary or oscillatory motions. It has the capability for high outputs of force and can produce high power per unit of weight and volume measurement.

MLC Motor

The multi- leaf collimator motors are known as MLC motor. These replacement parts of linear accelerators are used to accurately target the tumours in a radiation therapy by shaping the particle beams. They form a vital part in maintaining the capability of a LINAC machine to regulate the dosage of radiation for therapy sessions for different cancer patients. Hence, they are readily stocked to prevent the reduction of LINAC machine’s performance.

Long/Lat drive for patient table

One of the most common but important replacement parts of linear accelerators are the devices used for moving/ driving the patient table in and out of the machine along with side-to-side movement during the therapy sessions. If these devices are not working LINAC machines cannot be operated due to the inability to move patient in the desired position to do the radiation therapy.

Medical repair companies offering service contracts on radiation oncology equipment maintain and keep replacement parts of linear accelerators on hand will prevent you from technical issues created by the last-minute equipment failure. If you need further information about the replacement parts of linear accelerators and from where to procure them feel free to contact us.

Choosing Replacement Parts For LINACS

LINACS, which is short for linear accelerator, is a very important piece of equipment in the medical world. Linear accelerators utilize external beam radiation to destroy abnormal cells in the body, preventing the regrowth of tumors and most importantly, treating cancer without harming the healthy cells around it. LINAC technology is a combination of physics and engineering that is vital for saving lives, therefore, any hitches or glitches with the equipment is unacceptable.

Owing to the simple fact that most medical equipment needs regular maintenance to stay running properly and that a new linear accelerator will set you back a few thousands, if not millions of dollars, depending on the city, country of installation, as well as on the upgrades and features of each system, it helps to have around the clock access to a distributor of replacement parts for LINACS.

A linear accelerator contains hundreds of sensitive and sophisticated parts. If one LINAC part gets damaged, it can easily cause a ripple effect and bring an oncologist’s clinic to a halt for a few good days, especially if they don’t have instant access to a professional maintenance team let alone replacement parts for LINACS. This is why having a linear accelerator part supplier at the touch of a button is important. While buying a refurbished LINAC system may seem like the best way forward, oncologists can save thousands of dollars and get excellent value on quality replacement parts for LINACS when they buy them from a quality distributor who not only replaces the parts but will also offer regular repair services and solutions.

Cancer patients have to deal with a lot of life-threatening situations during their path to recovery such as infections. They need the reassurance that their doctors are taking every precaution necessary to ensure their safety. Radiation therapy has proven to be a highly effective method of cancer treatment, including relieving symptoms caused by more advanced cancers. Being a highly-targeted treatment that aims accurately at the cancer wherever it is in the body, radiotherapy contributes to about forty percent of all cancer cures and does a great job of alleviating cancer-related symptoms such as pain and in so doing, improves the quality of life for many cancer patients.

A linear accelerator is designed to deliver high does with precision and accuracy through photon beams to destroy cancer cells and diminish their ability to reproduce, which is why any malfunction should be addressed immediately to prevent any mishaps during treatments.

The Importance of On-Time Medical Equipment Repair

When you have a business in the medical field, you need to make sure that your equipment is running smoothly. When something breaks, you need to call a repair person quick or else you’ll have to reschedule appointments, which can hurt your bottom line. When your equipment needs new linear accelerator parts, you need a trustworthy repair company that will come out and fix it so that you can go back to running your healthcare clinic.

When you hire the right company, you want to make sure that they come out when they say they will because if they are late or not following the schedule, you’re not only losing money, patient care suffers. Your medical equipment is what makes your practice or clinic money and is imperative for seeing patients. When it’s broken, you need it up and running fast! You have no time to waste because broken medical equipment can take a while to repair, especially if you need to order special linear accelerator parts.

Finding a reliable medical equipment repair company is so important, you might want to look into having some back up refurbished linear accelerators just in case anything happens. This way, you’ll be able to still see patients while your other equipment is being fixed. You won’t have to shut down for the day or reschedule your patients since the refurbished linear accelerators in your office will work just as good as your primary ones.

Refurbished linear accelerators are merely older models that have been refurbished with new linear accelerator parts so that they’re in working condition. In fact, many run smoother than brand new equipment as it has had time for the kinks to be worked out. Having more than one machine in your practice means you won’t be rushed into finding an on-time medical equipment repair company. You won’t have to stress about not being able to accommodate patients and your repair person can take their time figuring out when your primary machine isn’t working properly. Although you ideally want to find an on-time medical equipment company to come out to service your machines, you won’t have as much of a headache knowing that you have a backup refurbished linear accelerator to handle your patient load in the meantime.

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.
