质量问题是各行各业的生命线,是赖以生存、发展的至关重要问题。放射质量亦然。无论是设备质量的保证、操作质量的保证,其最后是保证以最小的照射剂量,获得有价值的高质量影像,以达正确诊断的一系列有计划的活动。因此,放射质量保证和控制其理论基础有医用物理学、现代电子学、辐射防护学、放射技术与放射诊断学等相互渗透、相互结合的新 The quality issue is the lifeline of all walks of life and is a vital issue for survival and development. The same is true for radiation quality. Whether it is the guarantee of equipment quality or the guarantee of operation quality, it is ultimately to ensure that with the minimum dose of radiation, valuable high-quality images are obtained in order to achieve a series of planned activities that are correctly diagnosed. Therefore, the theoretical basis for radiological quality assurance and control is new interpenetration and combination of medical physics, modern electronics, radiation protection, radiation technology and diagnostic radiology.
