Computed Tomography Quality Assurance Services
Associates in Medical Physics, LLC, (AMP), will provide the following services:
Perform performance evaluation and compliance testing of each CT unit with respect to the following:
Accuracy of positioning lasers/lights
Slide thickness accuracy
Table-incrementing accuracy
Noise levels of the system in the Head and Body modes, and at various slice thicknesses
Image uniformity of the system in the Head and Body modes
High contrast resolution in the Head and Body modes, and at various slice thicknesses
Low contrast resolution in the Head and Body modes, and at various slice thicknesses
Determination of contrast scale (i.e., change in linear attenuation coefficient with CT number)
Determination of CT number linearity (i.e., establish constancy of contrast scale over the range of CT numbers of clinical interest)
Verify relative independence of absolute CT number of water with respect to subject size and kVp
General image quality with regard to imaging artifacts
General safety of the unit
Perform dosimetry measurements of each CT unit with respect to the following:
Physical location in an acrylic phantom (32cm Body or 16cm Head)
kVp
mA
Scan time
Scan diameter
Slice width
Provide a typed report of all findings for use as a permanent record, in a format acceptable to TJC and AOA.
