Abstract
Objectives: The Joint Commission (JC) released annual performance evaluation requirements for PET imaging systems in 2015 with limited guidance on best practices to achieve compliance in meeting the newly defined standards. Recognizing that over 80% of hospitals are JC accredited, and the potential demand for assistance in meeting JC requirements, we tested a prototype JC compliant phantom program that provides detailed technical instructions for phantom filling and data upload. In return, the end-user receives a comprehensive evaluation of scanner performance designed to meet JC requirements, including correctable actions, if warranted. Methods: The JC compliant phantom program requires acquisition of: (1) an off-axis uniform cylinder phantom, and, (2) either a NEMA Image Quality (IQ) phantom (at 4:1 contrast) or SNMMI Clinical Trials Network (CTN) oncology phantom (at 4:1 contrast). All 3 phantoms were prepared and scanned for purposes of evaluating the phantom program. Uniform and NEMA phantom preparation required a precision scale for measuring weight of phantom and water. Phantom fills were performed using [18F]-FDG dilutions and scan start times were approximately one hour post the initial [18F]-FDG assay. Scan acquisition and reconstruction parameters were per our institutional standard FDG oncology protocol as per program instructions. Image data and phantom fill data documentation were uploaded using a password-protected log in to access the cloud-based server. Results: Automated phantom analysis software downloaded and analyzed data, generating a full JC compliant scanner performance report in PDF format. System reconstructed resolution, system uniformity, absolute calibration, noise assessment, a recovery coefficient curve, lesion detectability, and artifact assessment were included in the report. A medical physicist reviewed images and the report for final approval. Conclusion: The JC compliant phantom program provides detailed technical instructions for phantom filling, acquisition, and data upload for any skilled technologist to follow. Generated reports easily delineate scanner performance metrics and JC compliance.
