Routine quality control tests are required to show that a nuclear imaging gamma camera is operating within the manufacturer’s design specifications. Therefore, it is recommended that spatial linearity and spatial resolution testing be performed weekly on each gamma camera in an active nuclear medicine clinic.
Typically, extrinsic testing (collimator in place) of the camera’s linearity and resolution is tested with one of three types of transmission test patterns: a four-frequency, equal-spaced bar pattern, usually referred to as a “90° bar phantom,” a single frequency parallel-line equal-space (PLES) test pattern, or a single-frequency orthogonal hole test pattern. Unfortunately, none of these test patterns can quickly and easily provide all of the information you need, but the UB Gamma Camera Test Pattern can.
The UB Gamma Camera Test Pattern is an economical, timesaving, easy-to-use product that will revolutionize gamma camera quality control… while saving the average nuclear medicine facility thousands of dollars each year!
The pattern’s shadows are used to evaluate the camera’s spatial resolution (the ability to see small objects) and spatial linearity (the ability to correctly position image data).
