A comprehensive quality assurance (QA) program for a proton-beam therapy facility consists of procedures that ensure a consistent and safe fulfillment of the dose prescription as well as minimal radiation exposure to the personnel and the public. Practical implementation of a QA program depends on the details of the proton accelerator and the selected beam-delivery technique. In many cases, QA checks will be relevant only to the particular equipment or to the implemented technology. Very often the institution that has acquired a new proton-beam therapy facility plays the dual role of both manufacturer and user, and therefore the proposed checks are a result of research and development, and could be modified with accumulated experience.

The QA measurements described below follow the steps of . . . [Full Text of this Article]
