NEMA publishes the performance standards that medical device products and other electrical products should adhere to. In this guide, the following detector NEMA tests are covered: • Intrinsic Spatial Resolution and Linearity (ISRL): Verification test that evaluates the ability of the detector to create and maintain a linear shape. • Intrinsic Flood Field Uniformity (IFFU): Verification test that evaluates the uniformity of the detector’s flat image. • Intrinsic Energy Resolution (IER): Verification test that looks at the energy resolution of all events in the detector’s field of view. • Intrinsic Count Rate Performance (ICRP): Verification test that looks at the maximum count rate that a detector can display. • Multiple Window Spatial Registration (MWSR): Verification test that looks at the difference in position shown on the detector for isotopes with very different energy windows. The user can access the NEMA detectors tests on the acquisition console by navigating to Admin Portal > Quality Assurance Tab > MI Quality Assurance > NEMA – Detector. SIEMENS Error!

Placing the source 25.9in (65.8 cm) away from the detector is referred to as 1FOV, so placing the source 129.5in (327.6cm) away from the detector is known as 5 FOV. This setup is used to ensure that the distance between the detector and source is large enough that every pixel of the detector is receiving roughly the same amount of activity from the source. 5 FOV Required materials: • Floor-to-Wall Source and Pole Source Holder • Laser Pointer with Leveler Setup and procedure: 1. Place the appropriate NEMA pattern on the detector that is being tested and a collimator on the other detector. 2. The center of the detector (PMT 30) must be at least 5 FOV from the source. This 5 FOV setup can be done one of two ways: SIEMENS Error!
