Interventions
This is a feasibility study, without any impacts on the surgical procedure itself. The total study-related delay of the surgical procedure will be approximately 10 minutes. Participation in the study
Surgery starts according to the standard procedure, which includes incision and preparation of the internal tissue required for the surgery. For this study, optimal ultrasound image acquisition of the
or other relevant arteries and bones close to the target area. For offline validation of the registration accuracy, a sterile electromagnetic pointer is used to pinpoint several anatomical landmarks,
