Area of Science:

  • Medical technology
  • Surgical navigation
  • Image-guided surgery

Background:

  • Laser range scanners (LRS) offer non-contact surface scanning for enhanced registration accuracy in image-guided surgery (IGS) systems.
  • Current LRS solutions for laparoscopic liver surgery are limited by expensive, bulky equipment, hindering integration into surgical settings.

Purpose of the Study:

  • To develop a novel, compact, and cost-effective LRS-based IGS system specifically for laparoscopic liver procedures.
  • To overcome the integration challenges of existing LRS technology in surgical environments.

Main Methods:

  • A triangulation process computes 3D laser point coordinates using existing IGS system tracking devices.
  • A compact and cost-effective LRS is utilized, facilitating integration into laparoscopic setups.
  • 3D laser points are reconstructed into a surface for multi-level registration with preoperative liver models.

Main Results:

  • The proposed system demonstrates submillimeter scanning precision and accuracy comparable to existing literature.
  • Quantitative analysis confirms a patient-to-image registration accuracy (target registration error) of [Formula: see text].

Conclusions:

  • The developed LRS-based registration approach is expected to accelerate the adoption of LRS techniques in surgical environments.
  • Future research will focus on optimizing scanning time and incorporating respiratory motion compensation.
