On what basis should uniformity flood images of each gamma camera be performed?

Uniformity flood images of each gamma camera are typically performed daily to ensure that the camera is functioning optimally and producing accurate, reliable images. This daily quality control procedure helps to identify any inconsistencies in the camera's imaging quality that may arise due to factors like detector non-uniformities, degradation of the camera's components, or changes in the system over time.

By conducting these uniformity checks each day, technologists can quickly detect and address any issues that could affect patient care or the quality of diagnostic images. Regular monitoring through daily uniformity testing helps maintain the integrity of the imaging process, ensuring that any deviations from established standards are recognized and resolved promptly, thereby enhancing overall patient safety and diagnostic accuracy.

Longer intervals, such as weekly, monthly, or yearly checks, may not provide adequate oversight of potential issues that could develop in a gamma camera, which is why the daily frequency is recommended for this specific quality control measure.
