Panels A and B show an axial and sagittal view, respectively, of the
intra-patient DIR of scan-9 on the reference image (scan-1). Green or red-violet
indicates inconsistency in the registration between the images. Panels C and D
show a color wash representation of DDM (mm) superimposed over an axial slice
and a sagittal slice, respectively, on scan-1. The color bar is scaled to
emphasize DDM values in the prostate region. Contours are shown for the rectum
(blue), prostate (red), bladder (yellow), and DDM-VOI (green).
