Adaptive proton therapy

Physics in Medicine & Biology, 2021
Abstract Radiation therapy treatments are typically planned based on a single image set, assuming that the patient’s anatomy and its position relative to the delivery system remains constant during the course of treatment. Similarly, the prescription dose assumes constant biological dose-response over the treatment course.

Proton Therapy

Hematology/Oncology Clinics of North America, 2019
Proton therapy is a form of external beam radiotherapy that has several advantages over conventional photon (x-ray) radiotherapy. Protons are useful in 2 scenarios that apply to a large proportion of cancer patients: lack of exit dose allows for delivery of a therapeutic radiation dose to tumors in challenging anatomic locations, and reduction in ...

Proton Therapy in Japan

Radiation Research, 1985
There are two facilities for clinical trials with protons in Japan: the National Institute of Radiological Sciences (NIRS), Chiba, and the Particle Radiation Medical Science Center (PARMS), University of Tsukuba. At the National Institute of Radiological Sciences, patient treatment with the 70 MeV proton beam began in November 1979, and 29 patients ...

A proton therapy system in Nagoya Proton Therapy Center

Australasian Physical & Engineering Sciences in Medicine, 2016
The purpose of this paper is to describe an outline of a proton therapy system in Nagoya Proton Therapy Center (NPTC). The NPTC has a synchrotron with a linac injector and three treatment rooms: two rooms are equipped with a gantry and the other one is equipped with a fixed horizontal beamline.

Proton Beam Therapy

Annual Review of Biophysics and Bioengineering, 1982
Conventional radiotherapy with high energy photons and electrons has been remarkably successful in treating many localized tumors. However, if tumors are large or are located very close to critical normal structures, it becomes very difficult to deliver a tumoricidal dose to the entire tumor volume without compromising the function of these adjacent ...
