A short while later in 1954, a 6 MV linac was installed in Stanford, USA, which began treatments in 1956. Medical linear accelerators accelerate electrons using a tuned-cavity waveguide, in which the RF power creates a standing wave. Some linacs have short, vertically mounted waveguides, while higher energy machines tend to have a horizontal ...
Conventional refers to the way the treatment is planned or simulated on a specially calibrated diagnostic X-ray machine known as a simulator because it recreates the linear accelerator actions (or sometimes by eye), and to the usually well-established arrangements of the radiation beams to achieve a desired plan. The aim of simulation is to ...
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 ...
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.
This accelerator will be delivered early next year to First Coast Oncology in Jacksonville, Florida, a leading physician owned radiation oncology center. All 2013 and early 2014 MEVION S250 ...
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.
The breakthrough came in 1997, with the introduction of a miniaturized, self-shielded, mobile linear accelerator (Mobetron, IntraOp Corporation, US) [11] and a mobile but unshielded linear accelerator (Novac, Liac–SIT, Italy). More than 75,000 patients have been treated with electron IORT, almost half of them since the introduction of mobile ...
Fast neutron therapy utilizes high energy neutrons typically between 50 and 70 MeV to treat cancer. Most fast neutron therapy beams are produced by reactors, cyclotrons (d+Be) and linear accelerators. Neutron therapy is currently available in Germany, Russia, South Africa and the United States.
