Necessity and Measures of Quality Assurance in Radiotherapy

The radiotherapy performed today is not uniform in quality and the end results obtained differ widely depending on the diversity of quality. As clinical study trials including radiotherapy modality have become more prevalent, the need for quality assurance (QA) in this field has emerged. In Japan, clinical trials have mainly been conducted by medical oncologists. The complication rate that medical oncologists assumed to be due to radiotherapy has become conspicuous and the necessity for QA arose.

Measures and procedures for QA in the radiation oncology field can be classified as operational aspects, physics and technical aspects and clinical aspects, according to the World Health Organization (WHO) (1). Physics aspects, techniques and operational aspects are represented by site visits and mailed thermoluminescent dosimeter (TLD) programs for dosimetric intercomparisons and follow-up of calibration procedures. Other procedures are aimed at detecting and scoring deviations from criteria defined in the protocol and . . . [Full Text of this Article]
