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.
