BACKGROUND In radiation therapy with ion beams, lateral distributions of absorbed dose in the tissue are important. Heavy ion therapy, such as carbon-ion therapy, is a novel technique of high-precision external radiotherapy which has advantages over proton therapy in terms of dose locality and biological effectiveness. METHODS In this study, we used Monte Carlo method-based Geant4 toolkit to ...

Background: High-velocity carbon ion beams represent the most advanced tool for radiotherapy of deep-seated tumors. Currently, the superiority of carbon ion therapy is more prominent on lung cancer or hepatomas. Materials and Methods: The data for lateral straggling and projected range of monoenergetic 290 MeV/u (3.48 GeV) carbon ions in muscle tissue were obtained from the stopping and range o...

fter 14 years of construction, the Large Hadron Collider, the world’s largest particle accelerator, fired its first beam of protons in September from its home at the European Organization for Nuclear Research (CERN) near Geneva. Now a spinoff technology for treating cancer is also nearing its European debut. The first European center to offer carbon ion therapy — a type of radiation treatment t...

according to the english literature, various lasers and light sources (i,g. argon ion lasers, pulsed ktp lasers, diode lasers and nd:yag lasers, pulsed dye laser(pdl), intense pulsed light sources (ipls) are applicable for the treatment of different vascular lesions. these conditions are the most important indication for laser therapy. this review summarizes the current literature on ipl with r...
