What is the goal of performing a uniformity test on a gamma camera?

The goal of performing a uniformity test on a gamma camera is to assess whether the camera produces consistent images across its field of view. This is crucial because any variation in image quality can impact the diagnosis and treatment planning based on the images obtained. Uniformity testing checks for discrepancies in sensitivity and signal detection across different areas of the imaging detector, ensuring that the gamma camera provides a reliable and accurate representation of the radiopharmaceutical distribution in the patient. This consistency is vital for achieving accurate diagnostic results and facilitates the comparison of images over time or between different patients.

While calibration, speed of image acquisition, and patient safety are important aspects of a gamma camera's overall performance and operation, they do not specifically relate to the primary goal of uniformity testing, which focuses on the consistency of image quality across the camera's field.
