General workflow of the system: an ab-3D-US image is taken immediately after the PET/MR imaging. The transformation between the ab-3D-US and the PET/MR image modality can then be performed by simple calibrations using the OTS. The 3D-ab-US/3D-ab-US registration is replaced by a direct intra-modal ab-3D-US/3D-TRUS registration, to fuse the 3D free-hand TRUS with the pre-procedure PET/MR image.
