Application of noise filtration schemes for two clinical cases. The Luca CCD was used to measure the light spot produced by miniature scintillation detectors. (a) Image obtained from the CCD camera with and without filtration of a miniature scintillation detector light spot on an image acquired without electron multiplying over a 5 s period. (b) Profile of the fourth light spot shown in (a). (c) Image obtained from the CCD camera with and without filtration of a miniature scintillation detector light spot on an image acquired with electron multiplying over a 500 ms period. (d) Profile of the third light spot shown in (c).
