Linear Accelerators

Treatments are given with a Linear Accelerator, which generates and delivers high energy x-rays that kill cancer cells. There are several options for treatment, and the Radiation Oncologist will determine which you will receive based on your individual treatment plan. 

St. Rita’s Medical Center has invested in state-of-the-art equipment, and was the first community hospital to have the Varian TrueBeam Linear Accelerator.

The TrueBeam system is the most advanced radiotherapy system available to pinpoint accuracy and precision in treating cancer. It integrates advanced imaging and motion management technologies in order to provide treatments faster while being able to monitor and compensate for tumor motion within the body. 

  • Treatment times are much shorter – more comfortable experience for the patient, reduces the chance of tumor motion during treatment, which protects nearby healthy tissue and critical organs.
  • Increased precision – with advanced imaging and motion management, precision is measured and detected in increments less than one millimeter. This capability enhances the precision of IMRT – Intensity Modulated Radiation Therapy treatment.
  • TrueBeam imaging technology can produce three-dimensional images to fine tune tumor targeting, both prior to and during treatment. This technology is called IGRT – Image Guided Radiation Therapy and uses OBI – On Board Imaging to view the location of the targeted area in real time. 
  • Ability to offer RapidArc radiotherapy, which makes it possible to greatly decrease the treatment time because the dose is being delivered in a continuous rotation of the treatment machine and precisely target tumors with great speed. 
  • Ability to offer Stereotactic Body RadioTherapy (SBRT), which is a high dose/small number of treatments therapy primarily used for treatment of lung cancer. 
    TrueBeam from Varian. Fast. Powerful. Non-invasive. This state-of-the-art technology allows physicians to choose the best treatment technique for each patient. 
 
Since each treatment plan is individualized, not every patient has the same treatment event if they have the same type of cancer. Patients receiving radiation therapy visit the center five days a week for up to eight weeks.
