(a) Prostate surface rendering such that the prostate base is facing toward the right, where blue represents regions where the MRI image was misaligned external to the prostate surface on TRUS and red represents regions where the MRI image was misaligned internal to the prostate surface on TRUS. (b) 2D axial image on TRUS displaying a region of large misalignment distal to the TRUS probe, where brown represents the expert delineation of the prostate on TRUS. (c) 2D axial image on TRUS displaying a region of misalignment near the TRUS probe, where brown represents the expert delineation of the prostate on TRUS.
