This workbook has been designed for use in conjunction with the manual, "Photographic Quality Assurance in Diagnostic Radiology, Nuclear Medicine and Radiation Therapy." Presented are several typical problems arising from the existence of variability and fluctuations in the automatic processing of radiographs, which unless corrected, can contribute significantly to increased patient dose, increased incidences of retakes, and poorer image quality. Each problem is presented as an exercise followed by a step-by-step reasoning process, so that the probable cause and appropriate corrective measures can be determined. (CS)
