    Ultrasound imaging is crucial for localizing hepatic tumors during surgery but has limitations, including operator dependency and disruption from electrocautery.

  • 2

    Image-guided surgical navigation provides a 3D model of the liver, improving localization of small and vanished lesions compared to conventional methods.

  • 3

    Current navigation systems face challenges due to organ deformation and reliance on preoperative imaging, leading to potential inaccuracies during surgery.

  • 4

    A prospective study at the Netherlands Cancer Institute evaluated an electromagnetic guidance system for 3D liver modeling from intraoperative ultrasound.

  • 5

    The study included 25 patients with tumors visible on ultrasound, aiming to optimize surgical workflow and assess the accuracy of the navigation system.
