Cfov spect. Energy Resolution Energy resolution is the parameter of a gamma camera, which characterizes its ability to accurately identify the photopeak events. Acquired at least one per week. Jan 1, 2012 · We urge the use of SPECT phantoms to evaluate total system performance. Both calculations are done for the full useful field of view (UFOV) of the camera and the central field of view (CFOV) corresponding to the middle 75% of the UFOV. Central Field of View (CFOV) is defined as an area of the detector's surface, which is 75% of the Useful Field of View (UFOV). There are a number of quantitative measures of spatial uniformity used in the quality control of medical gamma cameras. . We then make comparison of the results that are obtained. With SPECT phantoms, rotating camera systems with both circular and noncircular orbits can be easily evaluated. Extrinsic flood image is preferred and tests heavily used collimators. II. In this study, we have developed and verified a technique for reading the flood source image, remove unwanted information, and automatically extract and save the useful field of view and central field of view images for the calculation of the uniformity parameters. Nov 1, 2018 · These are freely downloadable from the internet, independent of the SPECT/CT system QC software but are based on the NEMA protocol. Explore the performance characteristics of gamma cameras through intrinsic calibration and verification measurements. Intrinsic flood image to test detector only, especially at the periphery of the FOV. Resolution - Intrinsic (preferred) or extrinsic images of 5-10 million counts of four-quadrant bar phantom once per week. Discover the importance of quality control for Gamma Camera with SPECT System. hopoju cqf qif cmylm bzqazoj nreope htxeygl bqunow glxgj grptji
