Application of ABCD double feedback management in quality assurance of diagnostic radiology

This method combines modern management and statistical methods with traditional film-reading systems to form a new retrospective and prospective film-reading system for quality assurance in X-ray diagnostic imaging. This method also provides feedback information with A, B, C, D and W factors which reflect the drawbacks of the radiographs. The ABCD double-feedback management system is an imaging quality evaluation system which concentrates on several important time and space periods in the radiographic engineering process. It incorporates adjustment of the X-ray apparatus and its functional capacity, selection of X-ray equipment, and application of the technician's experience and duty in the X-ray room and dark room.
