ABSTRACT
TG-103 (Halvorsen et al. 2005). It is critical that the QA program cover both the clinical as well as the physical aspects of treatment planning and delivery, as errors can occur from a myriad of sources in the clinical environment. Of possible errors, the most catastrophic are the errors made by a medical physicist (Figure 27.1). A quality audit addresses potential catastrophic errors and provides a comprehensive analysis with constructive criticisms to aid the supervising medical physicist in improving upon the overall QA program (British Institute of Radiology 1983, 1996; Hendee and Orton 2008).
