Compact system targets cancer more precisely.A new compact radiation therapy system that relies on proton beams can target cancer more precisely than conventional methods, according to according to prep. 1. As stated or indicated by; on the authority of: according to historians. 2. In keeping with: according to instructions. 3. the technology's developers. Researchers said the compact machine is far less expensive than a full-scale version. Proton therapy Proton therapy is a type of particle therapy which utilizes a beam of protons to irradiate a tumor site. Introduction Proton therapy is of interest because of its ability to accurately target and kill tumors, both near the surface and deep seated within the body, while is an advanced form of radiation therapy that replaces the high energy x-rays High Energy X-rays or HEX-rays are very hard X-rays, with 80 keV - 1000 keV typically one order of magnitude higher in energy than conventional X-rays. They are produced at modern synchrotron radiation sources such as the beamline ID15 at the ESRF. of conventional radiation therapy with proton beams. While x-rays deliver energy to all the tissues they travel through, proton beams deposit almost all of their energy on their target, with a low amount of radiation deposited in tissues from the surface of the skin to the front of the tumor tumor: see neoplasm. , and almost no exit dose beyond the tumor. |
