Proton beam therapy for medulloblastoma.
It is heartening to read a report of good functional outcomes following proton beam therapy in young patients with medulloblastoma, including the absence of many unpleasant side eff ects that can occur after conventional photon therapy. The authors quote UK research, which criticises the current proton therapy treatment policy of dividing the x-ray (photon) equivalent dose by 1·1. This is done ...
متن کاملRole of beam orientation optimization in intensity-modulated radiation therapy.
PURPOSE To investigate the role of beam orientation optimization in intensity-modulated radiation therapy (IMRT) and to examine the potential benefits of noncoplanar intensity-modulated beams. METHODS AND MATERIALS A beam orientation optimization algorithm was implemented. For this purpose, system variables were divided into two groups: beam position (gantry and table angles) and beam profile...

Contrary to popular opinion, the concept of treating cancer using high energy beams of protons is not new. First conceived in 1946, following a period in which patients were treated only in laboratory facilities, the first hospital-based facility opened in 1990 at Loma Linda University Medical Center (United States). Currently there are 67 centres in operation, with a further 32 in the construc...
