Tracked Ultrasound for Patient Registration in Surgical Navigation During Abdominal Cancer Surgery

The goal of this observational pilot study is to evaluate the feasibility and accuracy of tracked ultrasound registration on patients undergoing abdominal cancer navigation surgery. The main research question is: Could tracked ultrasound be applied as an alternative to standard CBCT scanning in surgical navigation? Participants will undergo tracked ultrasound measurements of the pelvic bone on the operating room after patient anesthesia and before surgical incision.

Inclusion Criteria:Age ≥ 18Patients scheduled for tumor surgery in the abdominal/pelvic area and navigation surgery with a scheduled CBCT-scan in the ORPatients provide written 'informed consent'Exclusion Criteria:No exclusion criteria
