Summary
Brief summary (as posted)
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.

Arms and outcomes
Arms (1)
- label
- Patients scheduled for navigated abdominal cancer surgery
- description
- Patients are 18 years old or older. Patients are scheduled for tumor surgery in the abdominal/pelvic area and navigation surgery with a scheduled Cone Beam CT-scan in the operating room. Patients provide written 'informed consent'. The to be administered intervention is a percutaneous tracked ultrasound measurement of the patient's pelvic bone on the operating room after anesthesia.

- Device: Tracked ultrasound measurement
Primary outcomes (1)
- measure
- Accuracy of tracked ultrasound registration.
- timeFrame
- One day
- description
- To evaluate the accuracy of tracked ultrasound registration on patients undergoing abdominal cancer navigation surgery. This will be assessed using the target registration error in mm, where a lower error means a better outcome.
Secondary outcomes (2)
- measure
- Influence of patient position alteration on registration accuracy.
