Image-Guided Surgery (IGS) uses advanced imaging for surgical precision. Enhancing IGS requires intuitive interfaces to integrate it seamlessly into operating rooms as a routine tool.

Area of Science:

  • Medical Imaging
  • Surgical Technology
  • Computer-Assisted Surgery

Background:

  • Medical imaging evolved from simple X-rays to sophisticated 3D visualization.
  • Computer advancements significantly improved imaging quality, detail (anatomy, pathology, vascularity, function), and 3D capabilities.
  • Image-Guided Surgery (IGS) integrates various imaging modalities and patient registration for enhanced surgical procedures.

Purpose of the Study:

  • To review the advancements and current state of Image-Guided Surgery (IGS).
  • To highlight the importance of image registration and real-time instrument tracking in IGS.
  • To discuss the limitations of pre-operative imaging and the role of intra-operative imaging in IGS.

Main Methods:

  • Review of medical imaging evolution and its application in surgery.

  • Discussion of key IGS components: image registration, patient registration, and real-time instrument tracking.
  • Exploration of visualization techniques (stereoscopic, virtual reality) and intra-operative imaging modalities (iMRI, Ultrasound, electrophysiology).

    • Main Results:

    • IGS provides high-quality 3D images, enabling precise surgical guidance.
    • Accurate registration of images and real-time instrument tracking are crucial for IGS effectiveness.
    • Intra-operative imaging is vital to overcome the limitations of pre-operative imaging assumptions.
    • Stereoscopic and virtual-reality techniques enhance surgical visualization.

    Conclusions:

    • IGS is a valuable tool in modern surgery, offering significant improvements in precision and visualization.
    • The reliance on pre-operative imaging accuracy presents a challenge, often necessitating intra-operative imaging.
    • For IGS to become a routine surgical tool, the development of natural and intuitive human-computer interfaces is essential.
