How often is uniformity testing required on a scintillation camera?

Uniformity testing on a scintillation camera is required daily to ensure the accuracy and reliability of the images produced. This testing is critical because it helps identify any discrepancies in the camera's performance that could affect image quality. Uniformity tests check that the camera detects radiation evenly across its field of view, which is essential for accurate quantification of radiopharmaceutical distribution in diagnostic imaging. By performing this test daily, operators can promptly address any issues, minimizing the risk of diagnostic errors in patient scans. Regular daily checks ensure that any drift or malfunction is caught early, maintaining the optimal function of the imaging system.
