抄録

This is the transcription of a lecture at “The 21st Medical Standard Dose Study Meeting”. At first, the concepts of “Comprehensive QA for Radiation Oncology: Report of AAPM Radiation Therapy Committee Task Group 40” was analyzed.
Secondary, the lecture was focused on the activities of Radiological Physics Center of M. D. Anderson Cancer Center. The author had a chance to visit the Department of Radiation Physics and RPC, MDACC, after “World Congress on Medical Physics and Biomedical Engineering”, held in San Antonio. He observed the activities of Outreach Physics, and learned the importance of External Audit Program. Dr. William F. Hanson was invited to the previous meeting to make the special lecture, titled “Calibration System in Radiotherapy and Dosimetry Quality Assurance in the USA” (Medical Standard Dose, Vol.1, No.1,1-19,1996). His lecture and my visit to MDACC made good references to this part.
Thirdly, the activities of Department of Medical Physics in Memorial Sloan Kettering Cancer Center was introduced. The author had another chance of visiting MSKCC, after “Health Physics Society and AAPM Joint Meeting”, held in July 1995 in Boston. He reported his observations during his visit, including the facilities of the department, QA tests of high dose rate brachytherapy source and their activities as a Accredited Dosimetry Calibration Laboratory. Due to the limited space, only a portion of the third part is included in this transcription.
As the final conclusion, the importance of followings were emphasized to take a new step toward the comprehensive QA program, which are; establishing QA committee in medical institutions, which should represent many specialties, setting their QA program, which should be comprehensive, feedback loop should be included in QA program, quality assurance should be confirmed by external audit and QA program should be support by medical physicists.
