Interactive 3D Navigation System for Image-guided Surgery
Résumé
This paper presents a novel surgery navigation
system based on a three-dimensional (3D) imaging technique,
integral videography (IV). In our system, the 3D structure of the
object of interest is reconstructed using surface rendering and
corresponding pixel distribution methods. We developed a
high-speed algorithm that renders high-quality IV images from
the surface model in real time and allows interactions like rotating
and scaling to be done smoothly. Using the patient-image
registration method, IV images can be displayed with the correct
size and relative position with respect to the surgical instruments.
Experiments were carried out with various anatomical models,
and the results show that our system could be useful in many
clinical situations such as orthopedic surgery and neurosurgery.
