Quality Assurance and Quality Control at the Integrated Research Facility

Evaluating computed tomography performance under simulated conditions. Comparison of the radiodensity of materials that simulate the head, the body center (nylon), body water, and body bone (teflon) with the expected values (green lines) specified by the

The  Integrated Research Facility quality assurance and quality control program monitors the performance of imaging systems to ensure these standards are met:

  • A baseline (prior to imaging ) level of equipment performance for a given study protocol
  • Acquisition of uniform quality, artifact-free images through continuous assessment of imaging components during study execution
  • Coordination with vendor service staff to ensure consistency and accuracy of all imaging components used in data acquisition through planned maintenance
  • Development of simulation studies that validate the utility, accuracy, and precision of novel imaging biomarkers indicating disease severity or prediction of disease or treatment outcomes
