TECHNIQUE OF GENERATING SURGICAL INFORMATION FROM INTRA-OPERATIVELY AND PRE-OPERATIVELY ACQUIRED IMAGE DATA

Abstract

A technique of generating surgical information from intra-operatively acquired image data of vertebrae and pre-operatively acquired image data of the vertebrae is presented. A method implementation comprises obtaining first image segments each containing a different vertebra, wherein the first image segments have been derived by processing the pre-operatively acquired image data, and obtaining second image segments each containing a different vertebra, wherein the second image segments have been derived by processing the inter-operatively acquired image data. The method also comprises identifying pairs of the second image segments and the first image segments that contain the same vertebra, respectively, and determining a transformation per pair of corresponding image segments that registers the identified respective first image segment and the identified respective second image segment. Further, the method comprises generating surgical information based on the transformation and the identified first image segment. Still further, the method comprises augmenting the surgical information by tracking a surgical tool and causing an output device to visually output a navigational aid indicative of the tracked surgical tool relative to visualized vertebrae.
