Results
The primary physics instructor was certified in either diagnostic or radiologic physics by the American Board of Radiology. The mean number of physics instructors included two Ph.D. physicists, one M.S. physicist, one radiologic technologist, and two M.D.s with 8-i 5 years experience for each instructor. The relative extent of involvement of each category of instructor was not surveyed.

Handouts were the most frequently used materials (72%) with specific mention of the Radiological Physics Examination (RAPHEX), produced by the Radiological and Medical Physics Society of New York, in 68% of the responses. High on the list of materials that were never used were live video (92% never used it), audiovisual series (Society of Nuclear Medicine, 76% never used it; Radiological Society of North America, 59% never used it), and videotape (47% never used it).

The fact that audiovisual materials were not generally used by the programs surveyed may indicate a need forfurther development in this area on at least more promotion of existing materials. The radiologists’ survey also indicated a need for more coverage of computers. The current survey
indicates that the subject of computers currently takes up approximately 4% of didactic hours. Although percentage of class time is not an indication of the quality of instruction, it is interesting

tions.
Respondents were invited to submit written statements as suggestions for improvements of physics instruction or under the heading General Comments. A total of 48 statements were received, the full text of which is available from the AAPM Committee on Training of Radiologists. Most of the suggestions for improvement concerned the need for regular attendance (seven responses); the need to teach basic primciples that directly affect image quality, such as spending less time on radiobiology (six responses); and the need for high quality,
