Performance of a tracked ultrasound navigation setup for pediatric tumor surgery: a phantom study

1

Pediatric tumors often require neoadjuvant chemotherapy followed by surgical excision, complicating tumor localization during surgery.
2

Surgical navigation systems can improve outcomes in pediatric oncology by enhancing intraoperative tumor localization using preoperative imaging.
3

The study developed a specialized ultrasound navigation system for pediatric tumors, addressing unique anatomical challenges in children.
4

Phantom models were created to evaluate the accuracy and precision of the navigation system in a controlled environment before clinical use.
5

The navigation system utilized electromagnetic tracking and ultrasound imaging to align preoperative models with real-time surgical contexts.
