    Abstract

    Preoperative planning for surgery is usually performed according to multiphase CT acquisitions: liver arteries and liver veins are provided from two different contrasted CT images. However, these images must be registered as they are acquired at breath hold, which are usually not identical. In this paper, we tackle this issue by providing a non-rigid registration method between the 3D liver models extracted from both preoperative images. This method is based on geodesic distance maps according to relevant landmarks and is divided in two steps: an original deformation field computation on liver surface according to geodesic distance and a biomechanical deformation of a volume mesh using our deformation field. We evaluate our method using four sets of images illustrating our clinical context. Results show that the average registration accuracy is below 1 mm for liver surface and within 5 mm for liver vessels.
