Cancer Therapy with Particle Beams
Particle beams, i.e. proton or ion beams, have a depth dose distribution with a maximum at the end of the particle track, which makes them exceptionally useful for radiosurgery, especially cancer treatment. This article gives a short summary of different types of radiation and points out the advantages of particle beams. It will then cover basic aspects of the theoretical description before exp...
متن کاملTumour Therapy with Particle Beams
Photons are exponentially attenuated in matter producing high doses close to the surface. Therefore they are not well suited for the treatment of deep seated tumours. Charged particles, in contrast, exhibit a sharp increase of ionisation density close to the end of their range, the so-called Bragg-peak. The depth of the Bragg-peak can be adjusted by varying the particle’s energy. In parallel wi...
متن کاملParticle therapy for noncancer diseases.
Radiation therapy using high-energy charged particles is generally acknowledged as a powerful new technique in cancer treatment. However, particle therapy in oncology is still controversial, specifically because it is unclear whether the putative clinical advantages justify the high additional costs. However, particle therapy can find important applications in the management of noncancer diseas...
متن کاملParticle Therapy Patient Scheduling: First Heuristic Approaches
The Particle Therapy Patient Scheduling Problem arises in radiotherapy used for cancer treatment. Previous contributions in the existing literature primarily dealt with photon and electron therapy with a one-to-one correspondence of treatment rooms and accelerators. In particle therapy, however, a single accelerator serves multiple rooms in an interleaved way. This leads to a novel scenario in ...
متن کاملParticle Therapy that is Easy on Patients
Hiroshi Akiyama, Ph.D. Kenta Mochizuki Masumi Umezawa OVERVIEW: Hitachi has drawn on the beam control technology it built up through its participation in large accelerator projects to enter the market for particle therapy systems, with five facilities currently in operation and five more in commissioning or under construction. Current marketing focuses on systems that use the spot scanning tech...
