Varian TrueBeam Linear Accelerator, used for delivering IMRT Intensity-modulated radiation therapy (IMRT) is an advanced type of high-precision radiation that is the next generation of 3DCRT. [ 77 ] IMRT also improves the ability to conform the treatment volume to concave tumor shapes, [ 10 ] for example when the tumor is wrapped around a ...
The Network is partnering with Palo Alto, California-based Varian to replace the six linear accelerators in the four hospitals, representing a significant upgrade in capabilities.
Varian Medical Systems is an American radiation oncology treatments and software maker based in Palo Alto, California. Their medical devices include linear accelerators (LINACs) and software for treating cancer and other medical conditions with radiotherapy , radiosurgery , proton therapy , and brachytherapy .
Radiation therapy is commonly used in prostate cancer treatment. It may be used instead of surgery or after surgery in early-stage prostate cancer (adjuvant radiotherapy). Radiation treatments also can be combined with hormonal therapy for intermediate risk disease, when surgery or radiation therapy alone is less likely to cure the cancer.
The device consists of a small linear accelerator attached to a robotic arm, along with an integrated image guidance system. During treatment, the image guidance system captures 3D images , tracks the movement of tumors , and guides the robotic arm to accurately aim the treatment beam at the moving tumor.
Like a conventional machine used for X-ray external beam radiotherapy (often referred to as a linear accelerator or linac, their main component), it [the tomotherapy machine] generates the radiation beam, but the external appearance of the machine, patient positioning, and treatment delivery differ. Conventional linacs do not work on a slice-by ...
