摘要 随着平板型DR成为数字化X线摄影的主流技术以来,量子检测效率(DQE)作为其成像质量的综合表征参数被普遍采用。临床影像专业人员熟悉该参数的技术内涵,有助于技术质量管理工作的开展。 Since the flat-panel DR has become a mainstream technology of digital X-ray imaging, detective quantum efficiency is commonly used as the parameter of image quality evaluating. It will help to carry out the quality control if the doctors are familiar with this technology.
