1. A navigation system for registering an image space to a physical space relative to a patient for a surgical procedure, comprising:
- a tracking system including a localizer and a tracking device;
a system operable to access intraoperative image data of the patient that was acquired at a determined position relative to the patient in the physical space;
a processor operable to at least one of determine a position of the tracking device in the physical space, determine an intraoperative image data fiducial point in the intraoperative image data, determine a preoperative image data fiducial point in a preoperative image data, correlate the intraoperative image data and the preoperative image data with the intraoperative image data fiducial point and the preoperative image data fiducial point, or combinations thereof;
wherein the preoperative image data is operable to be registered to the physical space to correlate points in the preoperative image data with corresponding points in the physical space based upon the intraoperative image data that was acquired at the determined position relative to the patient;
wherein the registered preoperative image data allow navigation of the tracking device in the physical space relative to the preoperative image data;
wherein the processor is operable to determine the position of an intraoperative imaging system to determine a position relative to the determined intraoperative fiducial image data point in the physical space.

Abstract
A system to allow registration of a patient to image space is disclosed. The registration can be performed without touching a plurality of fiducial points on the patient or in the image data. The registration process can eliminate manual steps of image to patient registration and image to image registration.

13. A method of registering an image space to a physical space relative to a patient, comprising:
-
accessing preoperative image data of the patient; determining a preoperative image data fiducial point in the preoperative image data; accessing intraoperative image data of the patient, wherein the intraoperative image data defines at least a portion of the physical space; determining an intraoperative image data fiducial point in the intraoperative image data; correlating the preoperative image data and the intraoperative image data using the determined preoperative image data fiducial point in the preoperative image data and the determined intraoperative image data fiducial point in the intraoperative image data; accessing a determined position of an intraoperative imaging system that acquired the intraoperative image data to determine a position of the patient within the physical space; and correlating the correlated preoperative image data to the physical space based at least on the accessed determined position of the intraoperative imaging system. - View Dependent Claims (14, 20, 21, 22, 23, 24)

25. A method of registering an image space to a physical space relative to a patient, comprising:
-
accessing a first image data set of the patient; determining a first image data set fiducial point; preparing the patient for a surgical procedure in at least a portion of the physical space; defining at least a portion of the physical space in a second image data set of the patient including at least determining a position of the patient in the second image data relative to a first imaging system; determining a second image data set fiducial point; correlating the first image data set and the second image data set at least in part by matching the first image data set fiducial point and the second image data set fiducial point; and registering the first image data set with the physical space with the correlation of the first image data set and the second image data set, wherein the physical space includes a space in which the patient is positioned and the registration allows for navigation of a member within the physical space relative to the first image data. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37)
