Abstract

The quality of medical radiation exposure from equipment for medical imaging and interventional procesdures is an important component of medical radiation safety. The purpose is to reduce radiation exposure to patients and workers while maintaining the image quality that is sufficient to achieve the purpose of the imaging or interventional procedures. Among the equipment in diagnostic radiology, medical exposure quality assurance has been enforced for mammography and computed tomography (CT) systems since 2007 and 2011, respectively, according to the Article 17 of Ionizing Radiation Protection Act in Taiwan. Since then, the quality assurance programs in facilities have been continuously inspected. The purpose of this project is to help the Authority to continue inspecting the medical exposure quality assurance programs for CT and mammography units in sampled facilities. In addition, methods or data that are useful for the future development of quality assurance procedures of these two modalities will be proposed or generated, e.g. size specific dose estimation for CT, screening examinations for CT and testing methods for digital mammography. For fluoroscopic systems, onsite survey and measurements will be conducted. In addition, hands on training and comparative studies between various equipment will be conducted. The purposes include not only to provide the current status of the medical exposure data from fluoroscopy equipment in Taiwan, for the Authority to implement related quality assurance standards, 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. To achieve these goals, this project propose to accomplish three specific aims within a period of two years: 1. CT systems: Inspection of quality assurance programs, establishment of methods for size specific dose estimation, and obtain the dose distribution for the cardiac and lung screening exams. 2. Mammography systems: Inspection of quality assurance programs and establishment of a universal set of quality assurance procedures that can be applied to various kinds of units. 3. Fluoroscopy systems: Survey of the current status of medical exposure quality for fluoroscopy systems, compare different image quality tools for quality assurance testing and compare the differences in exposures between systems with image intensifier and flat panel detectors.
