Fig. 8

Average SUV per slice of phantom images for the urine shift pattern (a) and the tube curve pattern (b). The origin (x-axis) of the slice position corresponds to the left limit of the phantom in sagittal images from Figs. 7c and 9c (see images inside Graph). Red line: TFS 4-mm PET, green line: TFS 2-mm PET, blue line: MCS 4-mm PET. Black dots in b show the tube angle defined in Fig. 1b
