An annual calibration program has been developed verifying outputs as published by the American College
of Radiology (ACR), American Association of Physicists in Medicine (AAPM), American College of Medical Physicists (ACMP),
and the Joint Commission on Accreditation of Hospitals Organization (JCAHO) or American Osteopathic Association (AOA).
The parameters that will be tested are:
Contrast Scale
CT Scale Factor
CTDI values of body and head technique
Spatial Uniformity
Percent noise Calculation for head and abdomen
High & Low Contrast Resolution
Accuracy
Precision of head and body Techniques
Linearity
Table Increment
Artifacts
Check of safety features.
Selection of equipment to maximize performance and acceptance testing of newly installed CT
units is available through Unicon Physics Inc.
