HemOnc Today | Proton beam therapy may be the next great leap forward in radiationoncology. Supporters say the technology allows physicians to treat a broadspectrum of cancers with few adverse effects, while more precisely targetingtumor cells with higher doses of radiation. Detractors say proton ...
The Alberta Health Services, Cancer Care’s clinical practice guideline on "Proton beam radiation therapy" (2013) noted that "Members of the working group do not currently recommend that patients with prostate cancer, non-small cell lung cancer, or most lymphomas be referred for proton beam radi...
The number of proton therapy centers has doubled every 10 years since the beginning of proton therapy in 1954. Today there are 22 proton centers in clinical operation worldwide. In the past 5 years proton and heavy charged particle therapy have received a particular boost in Japan and in Euro...
The significance of definitive radiotherapy for sinonasal mucosal melanoma (SMM) is sill controvertial. T his study was to evaluate the role of high-dose proton beam therapy (PBT) in patients with SMM. The cases of 20 patients with SMM localized to the p
In intensity modulated photon radiation therapy (IMRT), the planning target volume (PTV) concept is used to account for setup uncertainties and respiratory motion for IMRT. PTV is defined by adding a site-specific empirically-determined margin to the internal target volume (ITV), which is, in ...
Proton therapy, or proton radiotherapy, uses a beam of protons to irradiate cancer tumors. The dose of protons is directed to a narrow range of depth, which helps reduce the entry and exit doses to healthy nearby tissues.Learn more about proton therapy. Where can you find our centers?
Radiation-induced losses of SpecTran and Corning optical fibers were measured in a proton beam at the UC Davis Cyclotron facility. The tests were conducted at different temperatures in the range 150 degrees Celsius to minus 150 degrees Celsius. The paper discusses the measurement setup, the environ...
depth, a proton beam allows delivering a conformal radiation dose by tuning and focusing the peak of the maximum released energy (the Bragg peak) on the selected volume3, sparing the surrounding healthy tissues. However, toxicities may still occur within or very close to the target, due to ...
The gafchromic film could be irradiated with this method using a 2 mm slitted 200 MeV proton beam. The isocenters of a room laser and digital radiography system were in good agreement. The size distribution of the isocenter by the star-shots method was <2 mm, which is the value ...
