Graphical user interface for joint space width assessment by optical marker tracking

Boekbijdrage - Boekabstract Conferentiebijdrage

Optical position tracking is an essential tool in computer-assisted interventions for intra-operative guidance. It allows to register a pre-operative model or surgery plan to the patient, providing additional support to the surgeon. In this paper, we propose a two-step procedure to register pre-operative digital surface models to the surgical scene based on optical marker data. First a paired-point matching is applied, followed by an iterative closest point registration step. Mapping the surface model to the camera system allows to compute properties like the joint space width and motion asymmetry. Our method can be generalised to any joint and has been made available through an open-source graphical user interface, enabling future research on surgical navigation systems.
