Evaluation of Average Glandular Doses in UAE Hospitals

摘要

A national survey of patient exposure in mammography started recently in the United Arab Emirates, within the framework of the IAEA regional project on patient exposure in radiology. In this respect, the survey began with seven participating hospitals, all users of digital mammography and it will be extended gradually to other groups of hospitals. The insufficiency of available qualified Medical Physicist teams and also of equipment, combined with the vast workload of all hospitals in the country do not allow a large scale survey at the moment. The main purpose of this work is to determine the Average Glandular Dose in mammography facilities using tissue-mimicking phantoms to ensure that exposed patients are not submitted to high X-ray doses. The AGD values determined by the Physicists were checked against the relevant international standards and compared to the AGD values generated by the mammography system. Prior to the dosimetry work, image quality and X-ray beam parameters were checked for compliance with the applicable standards.
