What is a common test performed on gamma cameras for quality control?

The common test performed on gamma cameras for quality control is focused on uniformity and spatial resolution tests. These tests are essential to ensure that the camera captures images accurately across the entire field of view and maintains the appropriate sharpness and detail of the images produced.

Uniformity testing checks for variations in sensitivity across the detector. A gamma camera should produce consistent results regardless of where the source of gamma radiation is positioned. This helps to ensure that images generated for diagnostic purposes are reliable and can be interpreted correctly by clinicians.

Spatial resolution tests assess the camera's ability to accurately depict the size and shape of the radioactive sources. High spatial resolution allows for better differentiation between closely situated structures, which is crucial in diagnostics. This capability plays a key role in detecting small lesions or differentiating between normal and abnormal tissue.

Together, these tests are vital quality assurance measures that help uphold the integrity of imaging processes in nuclear medicine.
