简要总结
Multimodal intraoperative minimal-invasive (laparoscopic or robotic) liver surgery images will be registered to each other. Explicitly, these are the ultrasound and laparoscope images. Once they are registered, they will reveal the hidden tumor's location to the surgeon in real time through augmented reality. The intraoperative augmentation will also be enriched with the preoperative data (e.g., CT or MRI). This will simplify minimal invasive liver surgery, improve surgical safety and accuracy. It will also shorten hospital stays and contribute to an overall better quality of life for the patient, which in return will reduce the health-care costs.

结局指标
主要结局
Analysis accuracy of the augmented reality by aligned with the intraoperative measurements
时间窗: 28 months
The accuracy of the augmented reality will be assessed based on how well the preoperative data will be aligned with the intraoperative measurements. In order to assess the accuracy, measurements of multiple distances between the center of mass (mean position) of different internal structures (tumors, anatomical vascular networks, anatomical landmarks) visible both in the preoperative imaging and in the intraoperative imaging will be used.
