105至108年放射診斷設備之輻射安全與醫療曝露品保作業研究 (105年度)

The purpose of this project is to survey and evaluate the equipment performance of about 501 CT units, 320 mammographic units and 450 fluoroscopic usnits. Based on on-site measurements, we could understand the current status of related quality assurance programs in hospitals, problems and required assistance. The study results may assist the competent authorities to keep track of its quality assurance works, as well as be references of sophisticated quality assurance policy. For fluoroscopic systems, on-site survey and measurements will also be conducted. The project proposes not only to provide the current status of the medical exposure data from fluoroscopy equipment in Taiwan, but also to help facilities to further improve their medical exposure quality from diagnostic the therapeutic procedures that use fluoroscopic systems, as well as to initiate the quality assurance process. Additionally, the project also aims to summarize the current international status for National Diagnostic Reference Level (NDRL) and Local Diagnostic Reference Level (LDRL). We plan to provide recommendations of standard protocols for establishing and using of the NDRL in Taiwan. The research of establishing and using LDRL will just apply to CT and mammography. Recommendations for NDRL for CT, mammography, and fluoroscopy of Taiwan will be reported after we completing the project. In addition, a consulting program for performing fluoroscopy quality control in hospitals and a protocal for establishing the digital mammography quality control procedures will also be included. To achieve the goals, this project proposes to accomplish four specific aims within a period of four years: (1) To inspect the quality assurance programs for CT and mammography systems installed in Taiwan, and to evaluate the quality trends after the regulation was enacted. Recommendations for improving the regulations will also be provided. (2) To survey of the current status of quality assurance programs for fluoroscopy systems. A consulting program for assitang hostipal deparments will be conducted. Recommendations for establishing the corresponding standards will be provided. (3) To put forth standard NDRL establishing protocols and to provide NDRL values for CT, mammography and fluoroscopy in Taiwan. The results will be also compared with the ones in other countries. The researches related to LDRL for CT and mammography will be included. (4) To establish the quality control procedures for digital mammography systems and to provide the related training course. Radiation protection materials of interventional radiological procedures for Radiologists and Cardiologists.
