研究概览
简要总结
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.
详细描述
Image-guided navigation surgery allows for full utilization of pre-operative imaging during surgery and has the potential of reducing both irradical resections and morbidity. Currently, registration is done by Cone-Beam CT (CBCT) scanning on the operating room (OR) prior to navigation surgery. However, standard CBCT scanning has several limitations, mainly limited availability on the hybrid OR and radiation exposure. Furthermore, standard CBCT scanning can only be performed in horizontal patient position, while the patient position mostly differs during surgery, such as the Trendelenburg position. The use of tracked ultrasound instead of standard CBCT could overcome these limitations, which might lead to an increased navigation accuracy and improved surgical outcomes. Therefore, the goal of this research 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?

结局指标
主要结局
Accuracy of tracked ultrasound registration.
时间窗: One day
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.
次要结局
- Influence of patient position alteration on registration accuracy.(One day)
- Measurement time of tracked ultrasound registration.(One day)
