Area of Science:

  • Minimally Invasive Surgery
  • Medical Imaging
  • Surgical Navigation

Context:

  • Laparoscopic surgery lacks tactile feedback and provides only surface visualization.
  • Advanced visualization is needed for surgical planning and intraoperative guidance.
  • Current methods limit the identification of subsurface structures like vessels and tumors.

Purpose:

  • To develop and evaluate 3-D navigation technology for laparoscopic surgery.
  • To integrate preoperative MR/CT data with a laparoscopic navigation pointer.
  • To provide interactive, image-guided control during surgical procedures.

Summary:

  • A 3-D navigation system using preoperative MR/CT data and a laparoscopic pointer was developed.
  • The system achieved rapid preoperative image registration (2 minutes) with high accuracy (7.1 mm).
