Overview

Phantom QA kits include objects to test resolution contrast uniformity and geometric accuracy across modalities. Regular phantom testing verifies system performance and detects degradation. QA kits support accreditation and regulatory compliance.

Modality Specific Phantoms

Different phantoms exist for CT MRI ultrasound and x ray testing. Each phantom targets modality specific metrics such as slice thickness or signal uniformity. Standardized phantoms enable benchmarking across sites.

Testing Frequency

Daily weekly and monthly tests are scheduled based on modality and clinical volume. Automated analysis tools streamline QA reporting and trend analysis. Immediate action is taken for out of tolerance results.

Documentation and Traceability

QA results are documented and trended to detect gradual performance changes. Calibration and corrective actions are recorded for audit readiness. Staff training ensures consistent test execution.
