A is correct. SDCEP advises that a dental radiography QA programme should encompass image quality, patient dose and equipment, image processing and viewing facilities, staff training, review of procedures and radiology audit. Image-quality analysis should occur at least every six months using at least 100 images, with different image types reported separately and the causes of diagnostically unacceptable images recorded. For digital imaging, at least 95% should be diagnostically acceptable; the film target is at least 90%. B and D lack systematic recorded analysis and proactive equipment or dose QA. C uses an insufficient sample, applies the film target to digital images and delays dose assessment. E includes appropriate image analysis but omits essential patient-dose, equipment, processing, training and audit components.
