Area of Science:

  • Medical imaging
  • Robotics
  • Surgical oncology

Background:

  • Intraoperative magnetic resonance imaging (MRI) offers real-time guidance for surgical procedures.
  • Enhancing the accuracy and utility of intraoperative MRI requires advanced image processing and robotic integration.

Purpose of the Study:

  • To improve image-guided treatments using intraoperative MRI.
  • To develop and evaluate methods for enhancing surgical precision and robotic assistance during MRI-guided interventions.

Main Methods:

  • Deformable registration of preoperative 1.5 Tesla MRI images to intraoperative MRI scans.
  • Development and testing of an MR-compatible needle-holding robotic system for surgical assistance.
  • Retrospective analysis of prostate cancer biopsy cases using deformable registration.

Related Experiment Videos

  • Evaluation of the MR compatibility and performance of the robotic system.

    • Main Results:

    • Deformable registration significantly improved image registration quality in prostate cancer biopsy cases.
    • The developed robotic system demonstrated good MR compatibility.
    • Robotic system maneuvering did not adversely affect intraoperative MRI imaging, and vice versa.

    Conclusions:

    • Deformable registration is a valuable tool for enhancing intraoperative planning and simulation in MRI-guided procedures.
    • The MR-compatible robotic system shows promise for active surgical assistance in procedures like prostate brachytherapy.
