Abstract

Radiation dosimetry plays a central role in the physics of radiation oncology because potentially lethal amounts of radiation are necessary for the successful eradication of malignant tumors in humans. It has been estimated that an accuracy of ± 5% for dose delivered in the entire irradiated volume is necessary. Some of the steps in the radiation therapy procedure that influence the accuracy of dose delivered to tumor and healthy tissues are: (a) diagnosis, staging, localization of tumor volume, dose prescription, and fractionation schedule; (b) calculation of dose distributions resulting from an optimum geometric arrangement of radiation beams; (c) simulation and execution of the treatment plan; and (d) recording and verification of dose delivered. In this long chain of events, the dosimetry calibration of radiation fields used under reference conditions is the starting point for the accurate delivery of prescribed dose.
