Ultrasound imaging is ideal for hepatic surgery guidance, but is has the disadvantage of limited field of view besides poor image quality. Fusing intraoperative ultrasound with preoperative data (multi modality registration) will solve these disadvantages and would be ideal during image-guided interventions. To achieve pre and intraoperative registration, the vessel features from both modalities will be used. During surgery the liver suffers considerable deformation that needs to be taken into account. These encompass the two main objectives of this project:
- Intraoperative vessel extraction from ultrasound and initial registration of preoperative model
- Liver deformation from bio-mechanical model driven from ultrasound vessels images
