Registration of liver CT scans from different points in time or different phases of contrast agent saturation is a highly demanded tool for computer aided diagnosis, operation planning and intervention. This work presents a complete registration workflow to precisely overlap scans from 4 different application scenarios including registration of pretreatment and post-treatment data as well as registration of multi-phase CT. Various state of the art techniques in shape modeling and matching, visualization as well as augmented interaction are applied to cover all of the described scenarios in a clinically usable system. Our system has been in use for clinical evaluation under real life conditions and has been tested on more than 30 patients.
