Illustration of variations in ${\mathrm{BAT}}_{\mathrm{TRF}}$ in four BAT estimation methods. Axial plane views of one of the slices of the ${\mathrm{BAT}}_{\mathrm{TRF}}$ timepoint map measured using four automatic estimation methods for PCa patient # 11: measured over TROI: (a) LL, (b) PL, (c) OQ, (d) PG and whole prostate gland (e) LL, (f) PL, (g) OQ, and (h) PG. The green solid line shows the boundaries of delineated ROI. The transparent parts of the BAT_TRF map inside the ROI are voxels that did not meet Eq. (8) conditions. (i,j,k,l) Histograms of the number of voxels assigned a specific ${\mathrm{BAT}}_{\mathrm{TRF}}$ timepoint over the whole prostate gland ROI in four methods. It should be noted that for patient #11, BAT_AIF was measured as timepoint 6; hence, the voxels below timepoint 6 are discarded in analysis.
