How Do Linear Accelerators Work to Treat Cancer?

A linear accelerator also considered as LINAC is a standard method of producing photons and electrons for radiation therapy treatments, generating energy for external beam radiation treatments for cancer. Linear accelerators now account for most of the treatment machines used today and are complex, computer-powered systems that deliver precise, highly controlled doses of radiation to treat patients. The linear accelerator triggers electrons to speed up as they penetrate a wave-guide and shoots the particles at a heavy metal target, forming high-energy x-rays. Lines of accelerated x-ray radiation are shaped to target a tumor or surgery site, limiting radiation exposure to healthy tissue while destroying the cancer cells.

For instance, a LINAC may be used during the whole breast or accelerated partial and Intensity-Modulated Radiation Therapy (IMRT). It can be brought into the operating room for intraoperative radiation therapy (IORT) during a lumpectomy for breast cancer.

Abilities of LINAC Technology

To avoid damaging healthy surrounding tissue with too high a dose of radiation during multi-session treatments, LINAC expertise are most frequently used. The most important use of LINAC technology may be its ability to target larger brain and body cancers with a reduced amount of damage to healthy surrounding tissues. The device also has several other medical uses. Its radiation can suppress the rejection of an organ transplant, restrain the immune systems of people undergoing marrow and blood replacement and alter certain cardiovascular neurological and disorders.

Receiving The Service Needed For Repairs

However, despite the numerous benefit of the LINAC, servicing linear accelerators can be a very demanding  job. Hiring full-time in-house technicians are mostly daunting as most medical facilities choose to work with a company that is on call to service medical equipment.

Linear Accelerators Deliver Accuracy in Patient Care

A linear accelerator is one of the best tools to use for eradicating tumors in a cancer patient. In the past, one of the problems with cancer treatment was that healthy normal cells were killed too. But with a LINAC, linear accelerator, this machine delivers elevated electrons or energy x-rays that conform to the tumor’s form. It focuses on destroying cancer cells while sparing the surrounding normal tissues.

LINAC systems also contain numerous incorporated measures of protection that will ensure that they only deliver the most accurate dosage to patients. Therefore, servicing linear accelerators is an extremely valuable part of the entire process, as well as requiring constant checking by a medical physicist to ensure that they continue working properly.

Before a Procedure Begins

A patient who has been scheduled for radiation therapy with a LINAC will undergo a long and stringent process to ensure accuracy and safety. This begins with an appointment with the radiation oncologist. The oncologist will then collaborate with the radiation dosimetrist and a medical physicist to develop the best treatment plan. Before treatment proceeds, the patient’s own doctor will review and double check this plan before it can begin.

There will also be quality assurance procedures put in place to ensure that the patient remains safe during the procedure. These procedures are also put in place so that if multiple treatments are required, that the patient will receive each one in the exact same manner.

A LINAC is most frequently used for external radiation beam treatment for patients with cancer. Linear accelerators treat all parts and organs of the body and the organs that may have cancer. The machine delivers high-energy x-rays or electrons to the center of the patient’s tumor. It destroys the cancer cells while sparing surrounding tissue.

How a LINAC Works

The LINAC uses a microwave technology that is like radar technology. It accelerates electrons so that they collide with a heavy metal target that produces high energy x-rays. These are shaped to conform to the exact shape of the patient’s tumor.

The patient lies on a movable couch during treatment. The patient must be in the right position for the most effective treatment. The couch can be moved up, down, left, right, and left in and out. The beam is directed from a gantry which is rotated around the patient.

There are a variety of experts who operate this equipment. It’s important that the LINAC be regularly serviced. There are qualified businesses who perform regular servicing of linear accelerators.

Repairs May Be Needed On LINAC Systems

In some instances, the LINAC may need to be repaired. The machine will deliver errors and reports and not turn on if it’s not safe. This is when clinics and hospitals need to call in technicians for repairing LINAC systems. It can be difficult to determine what has gone wrong, as the LINAC system is complex. It may simply need servicing, or it may need certain parts replaced.

Tips for Purchasing Refurbished Linear Accelerators

Servicing a LINAC system requires a lot of carefully planned procedures.  This is because servicing a linear accelerator incorrectly would have effects on the LINAC machine itself.  LINAC systems are very complex and sophisticated piece of medical equipment, hence one must be experienced to repair medical equipment of such complexity.

Refurbished VS New

A linear accelerator is a device commonly used for treating cancerous tumors.  Because of this singular reason, it is very difficult to really choose if getting new parts or repairing the machine is going to be feasible or if purchasing a new or refurbished linear accelerator is a better choice for your need.

Refurbished linear accelerators and refurbished parts are suited for both repairs and maintenance.  They are suitable for startup medical companies, research companies, and companies that are looking to purchase additional pieces.  The cost of purchasing a refurbished linear accelerator and accelerators parts are low in comparison to buying a new one.

Buying a refurbished linear accelerator is advantageous in growing a medical practice and managing expenses at the same time. There are important things to note when buying a refurbished linear accelerator.  It is imperative to plan. 

Factors To Consider When Planning A Purchase

Plan for a new piece of medical equipment by defining your clinical goals and what technology would bring your desired results before setting out to purchase the refurbished linear accelerator.  In planning, their important things you need to consider.

• SITE - Room dimension, power, water supply, local permits, room dimension, and future technology are very important considerations to be made when installing a radiation equipment such as a linear accelerator.
• BUDGET - The technology, manufacturer, and age of your acquired equipment is a function of your budget. This is one of the reasons why purchasing a refurbished linear accelerator is advised for startups - it affords them the chance to carry out another essential part of their practice.

Maintaining Radiation Oncology Equipment

Biomedical equipment technicians have the arduous job of repairing medical equipment used in hospitals and various health practitioner’s office. These machines are quite complex and carry out work that the normal human being can’t such as processing x-rays into visible images or magnifying test samples thousands of times, therefore any glitch, malfunction, or downtime is unacceptable because it can affect the entire medical procedure, which in all cases, is life-saving.

Technical Skills Involved With LINAC Servicing

Servicing LINAC systems takes a certain level of technical skills and the use of both mechanical skills and software know-how to fix the delicate parts of a linear accelerator. A LINAC uses microwave technology to create high energy electron beams or X-rays known as Photons beams. When these high-energy photons are created they are then directed to a patient's tumor and are shaped as they exit the LINAC to conform to the tumor

Servicing linear accelerators is time-consuming, nonetheless, they can be successfully operated, maintained and repaired, but only when done by people with a background experience in capacity building, installing, commissioning, calibrating, servicing and repairing linear accelerators. Components of a LINAC are highly sensitive suffice it to say, costly. Take, for example; the drive stand comprises of the klystron, which is also used in high energy physics, provides medical linacs with the source of microwave power to accelerate the electrons by amplifying introduced radio frequency electromagnetic waves. The job of biomedical equipment technicians is to not only get it right the first time but also to ensure that they check their work for any anomalies to alleviate future disruptions.

Components Of An Accelerator

Other components that a technician must check when servicing linear accelerators are the RF waveguide, the circulator, which connects the klystron and the RF waveguide, and the cooling water system, all, which are vital components of the drive stand that needs to work at optimal capacity. Additionally, the modular cabinet of the LINAC systems, which is located in the treatment room, contains three subcomponents that also need to work symbiotically. They are:

• The power distribution system
• The fan control that cools the power distribution system
• The auxiliary power distribution system which contains off button that shuts down the power to the LINAC in case of an emergency

The water cooling system that is located in the drive stand and gantry cannot be allowed to fail at any moment because not only does it provide thermal stability to the whole LINAC system, but it also allows all the components in the gantry and drive stand to operate at a constant temperature.
Equally so, the monitor ionizing chambers used to screen field symmetry, integrated dose and dose range, as well as the multi-leaf collimators (MLCs) that are used to create a block that spares normal tissue and direct the radiation dose to the tumor, are two important elements in the treatment delivery of radiotherapy.

Checked and Maintained For Accuracy

They, therefore, must be checked when servicing linear accelerators to ensure that there are accurate dosimetry, mechanical precision, and imaging during RT treatment.
