Abstract

Abdominal organs undergo large deformations due to intra-abdominal pressure (pneumoperitoneum) during laparoscopic surgery, especially large organs such as the liver [2]. These deformations cause large inaccuracies when using surgical navigation systems [2]. Fortunately, intra-operative imaging through CT/MRIcan be acquired in modern hybrid ORs as well as la-paroscopic ultrasound and can both be used to provide an updated organ models. However, these medical imaging modalities are expensive and may extendthe surgical workflow, hence, biomechanical models could be used as a solution for intra-operative regis-tration, also to account for organ deformations due to surgical manipulation. Within this study, we propose asolution to compensate for pneumoperitoneum, which could greatly increase the accuracy of liver surgical navigation systems.
