Radiation Output Reproducibility Measure the air kerma at the isocenter for each kVp station and a range of clinically used mAs setting. Compare the results to the baseline values established at the initial acceptance testing. The values should be +/-5% of the baseline. 3. kVp Accuracy Measure the kVp at all clinically used settings. The measured kVp should be +/-5% of the selected kVp. 4. kVp Repeatability Make five kVp measurements each for two clinically used kVp settings. All measured values should be +/-5% of the mean kVp. 5. kVp Reproducibility Measure the kVp at all available kVp settings. The measured values should be +/-5% of the baseline. 6. Beam quality Measure the half value layer (HVL) for aluminum.

The results of the technical QA program review shall be included in the written report. Any trends that identify problems shall be included in the report along with recommended corrective actions. 13. Display Monitors Perform a visual analysis of the SMPTE test pattern. Display the test pattern on the imaging console. Set the display window width/level to the manufacturer-specified values for the pattern. Do not set the window/level by eye; doing so invalidates the procedure. Examine the pattern to confirm that the gray level display in the imaging console is subjectively correct. Review the line pair patterns in the center and at each of the corners. Review the black-white transition. Look for any evidence of scalloping (loss of bit depth) or geometric distortion. Use a photometer to measure the maximum and minimum monitor brightness (0% and 100% steps) Measure additional steps within the pattern to establish a response curve. Measure the brightness near the center of the monitor and near all 4 corners (or...
