Fig. 3From: Validation of the physiological background correction method for the suppression of the spill-in effect near highly radioactive regions in positron emission tomographySchematic description of the background correction technique, as demonstrated for the XCAT2 phantom simulation. In this study, the bladder was automatically segmented from the XCAT2 phantom, but in principle, the hot region can be segmented from either the CT or MR imageBack to article page
