kVp Accuracy:

Measure the kVp at all clinically used settings. The measured kVp should be +/-5% of the selected kVp.

kVp Repeatability:

Make five kVp measurements each for two clinically used kVp settings. All measured values should be +/-5% of the mean kVp.

kVp Reproducibility:

Measure the kVp at all available kVp settings. The measured values should be +/-5% of the baseline.

Beam quality:

Radiation field of view (FOV):

Measure the width of the radiation field at the isocenter. The width of the beam should be 3 mm or 30% of the total nominal collimated width.

Image Quality:

Image the phantom provided by the manufacturer or another suitable phantom. Assess high contrast spatial resolution, uniformity of trans axial images, and image noise. Imaging uniformity shall be assessed over the entire range of axial images.

Accuracy of Linear Measurements:

Using images of an appropriate phantom, assess the accuracy of distance measurements.

Accuracy of Patient Dose Metric Indication:

Assess the accuracy of the indicated dose metric (typically DAP).

Patient Dose Assessment:

The qualified expert shall review the technical QA program. The review shall include a trend analysis of the QA data. 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.

Display Monitors:

b. 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.

c. Use a photometer to measure the maximum and minimum monitor brightness (0% and 100% steps)

d. Measure additional steps within the pattern to establish a response curve.

e. Measure the brightness near the center of the monitor and near all 4 corners (or all 4 sides, depending on the test pattern used).
