WebThe purpose of this study was to investigate the cause of a nonuniformity artifact seen on an intrinsic flood. Methods: Intrinsic floods were acquired on three different cameras using a point source in a 1-cc syringe, with and without a needle attached. Floods were obtained with the syringe placed perpendicular and parallel to the camera face. WebAug 27, 2016 · Intrinsic resolution, R i, is the component of spatial resolution contributed by the detector and associated electronics, and is a measure of how well an imaging device can localize an event on the image.Intrinsic resolution arises primarily from the statistical fluctuations in pulse formation that have been discussed in the section entitled Gamma …
