With computed radiography (CR) systems, laser printer-film processor combinations are normally checked daily by using test film three-point density measurements. In this study, the authors show that the recommended three-point quality assurance procedure can show satisfactory results even though the CR film output behaves in an anomalous manner. This problem can be corrected by using a 16-point calibration procedure. Regular 16-point calibrations should be performed to ensure satisfactory CR system performance.
