Fig. 4

Selected transaxial fusion slices of the phantom (9.34 GBq, average DTCF = 1.1903) corrected with DTCM1 (a and d) and DTCM3 (b and e, colour scale in counts), and parametric images of their relative count differences (c and f, colour scale in per cent). VOIs: whole phantom (red), large saline bag (a, b and c, orange), small saline bag (d, e and f, cyan) background (d, e and f, white). Of note, the peripheral hot objects mimicking target tissues exhibited minimal count differences (mostly black voxels, right)
