Which quality control test examines the linearity of a gamma camera?

The Conformity Test is designed to assess the linearity of a gamma camera. This particular test evaluates how accurately the camera can respond to varying levels of radioactivity across its detected range. It examines the relationship between the input activity and the output response of the camera, ensuring that the camera produces linear results across its operational spectrum. This is crucial for accurate imaging and quantification within nuclear medicine, as non-linearity could lead to significant errors in diagnosis and treatment planning.

Each of the other tests serves different functions in quality control; for example, the Uniformity Test focuses on the even distribution of detected signals across the imaging field, while the Calibration Test is aimed at adjusting the camera’s response to ensure accurate readings at specific known standards. The Resolution Test looks at the camera's ability to distinguish between two closely spaced sources. While these tests are vital for maintaining overall camera performance, none specifically examine linearity in the same way the Conformity Test does.
