This study introduces a 3D computer graphic program for brain tumor resection. The system provides real-time visualization and guidance, enhancing surgical precision and tumor removal.

Area of Science:

  • Neurosurgery
  • Medical Imaging
  • Computer-Aided Surgery

Background:

  • Brain tumor resection requires precise surgical navigation.
  • Current methods may lack real-time, integrated visual guidance.
  • Advanced visualization tools can improve surgical outcomes.

Purpose of the Study:

  • To develop and evaluate a 3D computer graphic program for intraoperative guidance during brain tumor resection.
  • To enhance surgical accuracy and completeness of tumor removal through real-time visualization.

Main Methods:

  • A stereotactic frame-mounted video camera captures the operative field in real time.
  • A computer-generated 3D model of the tumor is superimposed on the video feed.
  • The system adjusts the model to the surgeon's view and displays cross-sections at the resection depth.

Main Results:

  • The program guides surgeons from initial incision planning to final tumor removal.
  • Real-time cross-sectional views at measured depths provide continuous intraoperative feedback.
  • Tumor disappearance from the monitor signals completion of resection.

Conclusions:

  • The developed 3D computer graphic program offers a novel approach to brain tumor resection guidance.
  • This technology has the potential to improve surgical precision and reduce residual tumor.
  • Real-time, superimposed 3D modeling enhances intraoperative spatial awareness for neurosurgeons.
