QC Principles for CT

Explains quality control principles specific to CT: tests for image uniformity, spatial resolution, contrast resolution, and dose consistency. References ACR CT accreditation test methods and medical physics QC recommendations.

Routine QC Tests

Detailed descriptions of daily, weekly, and monthly QC tests: CT number uniformity phantom scans, slice thickness verification, CTDI measurements, and image quality scoring. Explains how to set action thresholds and log results.

QC Documentation and Response

How to document QC results in a logbook or electronic system, escalate out-of-tolerance results to a medical physicist or service engineer, and use sample corrective action templates and follow-up documentation for accreditation.
