Fig. 6

Sinogram profiles on halo-artifact regions from a random-corrected emission sinogram (thick black solid line), scatter sinogram (red solid line: TFS 4-mm, green solid line: TFS 2-mm, blue solid line: MCS 4-mm), and mask for TF-SSS (red region: for TFS 4-mm, green region: for TFS 2-mm). Patient data are shown in a and b. Phantom data are shown in c and d. Panels a and c are the urine shift pattern. Panels b and d are the tube curve pattern. e Example of sinogram images and profile lines
