What is the main purpose of a uniformity test in nuclear medicine?

• A. Check for camera wear and tear
• B. Ensure the camera accurately portrays distances/shapes
• C. Ensure uniform distribution of counts and check for cold/hot spots
• D. Calibrate the sensitivity of the gamma camera

Answer: (C)

The primary purpose of a uniformity test in nuclear medicine is to ensure a uniform distribution of counts across the imaging detector and to identify any cold or hot spots that may indicate issues with the camera's performance. This test is essential for verifying that the gamma camera is functioning properly and that it can accurately capture images without any artifacts caused by non-uniformities in its response. Uncorrected non-uniformity in imaging can lead to misinterpretation of images, potentially affecting diagnoses and patient safety. By assessing both uniformity and the presence of artifacts within the imaging data, technologists can ensure that the camera is performing optimally, which is crucial for producing high-quality diagnostic images. The other options relate to significant aspects of camera maintenance and functionality, but they do not specifically identify the uniformity test's primary goal of evaluating the evenness of response and identifying areas of anomalies in detection.
