Isocenter verification for linac‐based stereotactic radiation therapy: review of principles and techniques

摘要

There have been several manual, semi‐automatic and fully‐automatic methods proposed for verification of the position of mechanical isocenter as part of comprehensive quality assurance programs required for linear accelerator‐based stereotactic radiosurgery/radiotherapy (SRS/SRT) treatments. In this paper, a systematic review has been carried out to discuss the present methods for isocenter verification and compare their characteristics, to help physicists in making a decision on selection of their quality assurance routine.PACS numbers: 87.53.Ly, 87.56.Fc, 87.56.‐v
