The main goal of a diagnostic quality assurance program is to produce radiographs of consistent high quality ( 5). The nature and extent of this program will vary with the size and type of the facility and the type of examinations conducted. In order to produce a good quality image of anatomical structures for diagnostic purposes, both quality assurance program and quality control measures are of great importance ( 4).
The radiation dose to a patient is linked to image quality and should not be lowered to jeopardize the diagnostic outcome of a radiographic procedure. This repetition of radiographs presents various concerns including unnecessary radiation exposure for the patient, increased costs, longer patient waiting time, additional workload for radiographers and reduced x-ray tube life. Whenever a film is rejected, the radiograph must be repeated. A reject image is described as an image that does not add diagnostic information to clinical questions because of poor image quality, and thus, the image has to be retaken ( 1– 3). Some radiographs are discarded because they have no diagnostic value. Accordingly, the correct interpretation of this image is an important requirement for further action. Diagnostic imaging provides information about the internal anatomy and physiology of the The quality of a radiographic image plays an important role in the accuracy of the diagnostic process.
