A review of Surface Matching models: perspectives and challenges for Automatic Soft-Tissue Registration in Computer-assisted Interventions

Abstract

One of the main challenges related to Computer-Assisted Surgery (CAS) is the registration of multi-modal patient specific data to enhance the surgeon’s navigation capabilities by observing beyond the exposed tissue surface. One increasingly popular approach involves capturing the organ surface with a range imaging device and performing a shape-based registration. This paper (1) discusses the major challenges related to surface matching in the operating theater and (2) provides a general review of state-of-the-art methods in shape matching.
