Design outcomes

Primary

Measure	Time frame
To measure distances between the pointer tip held on surgical clips placed on the liver surface and the closest tumor border using the navigation, and to compare it to the actual distance measured in contrast-enhanced intraoperative XpercT (see measurement description).	—

Secondary

Measure	Time frame
* To assess the feasibility of intraoperative XperCT acquisition and registration to preoperative imaging. Feasibility is judged in visual inspection of similarity of the vessels and lesions on the images. * To determine the accuracy of the navigation system relative to anatomy before the start of liver surgery (liver border measurement) (in mm). * To evaluate the usability this the newly introduced technique for users (i.e. surgeons and surgical assistants).	—
