This document is historic for two major reasons. First, it represents the first jointly authorized publication by both American Association of Medical Physicists (AAPM) and American College of Medical Physics (ACMP). This document began as a 1991 ACMP report. In 1997 the General Medical Physics committee of AAPM invited Dr. Brahmavar, who authored the original report, to chair a task group to rewrite and update the document as an AAPM task group report. As it neared completion, there was a suggestion that perhaps ACMP would be interested in supporting the revised document. In the spring of 2000 it was independently approved by both organizations, each of which endorsed joint publication. This.
