Abstract
The method includes the steps of obtaining atlas data in an atlas coordinate frame from a computer-readable atlas of anatomical information, obtaining patient data in a patient coordinate frame that corresponds to obtained atlas data in an atlas coordinate frame, and morphing atlas data using a first morphing transformation between obtained patient data in a patient coordinate frame and corresponding obtained atlas data in an atlas coordinate frame. The apparatus includes a tracking system for tracking physical objects; a computer for receiving information on tracked objects, a computer program on computer readable medium for operation on the computer. The computer program includes instructions for obtaining atlas data in an atlas coordinate frame from a computer-readable atlas of anatomical information, obtaining patient data in a patient coordinate frame that corresponds to obtained atlas data in an atlas coordinate frame, and morphing atlas data using a first morphing transformation between obtained patient data in a patient coordinate frame and corresponding obtained atlas data in an atlas coordinate frame. One may build upon the summarized aspects to provide other useful methods and apparatuses for interventional guidance.
