1. An image guided catheter navigation system for guiding a catheter through a region of a patient, said navigation system comprising:
- an imaging device operable to generate image data of the region of the patient;
a tracking device operable to track the position of the catheter in the region of the patient;
a controller in communication with said imaging device and said tracking device and operable to superimpose an icon representing the catheter onto the image data of the region of the patient based upon the position tracked by said tracking device;
a display operable to display the image data of the region of the patient with the superimposed icon of the catheter, wherein said catheter provides a function to the region of the patient; and
a statistical atlas accessible by said controller;
wherein said controller is operable to identify a suggested pacing lead site based at least in part on the statistical atlas that is fit to the generated image data of the region of the patient.

Abstract
An image guided catheter navigation system for navigating a region of a patient includes an imaging device, a tracking device, a controller, and a display. The imaging device generates images of the region of the patient. The tracking device tracks the location of the catheter in the region of the patient. The controller superimposes an icon representing the catheter onto the images generated from the imaging device based upon the location of the catheter. The display displays the image of the region with the catheter superimposed onto the image at the current location of the catheter.

23. A method for image guiding a catheter in a region of a patient, said method comprising:
-
displaying an image of the region of the patient; navigating the catheter using a tracking device associated with the catheter through the region of the patient; detecting a location of the catheter in the region of the patient including sensing a field with a tracking system; displaying the location of the catheter on the image of the region of the patient by superimposing an icon of the catheter on the image; performing a function with the catheter when the catheter reaches a desired location; receiving a cyclic physiological signal; time gating the detection of the location of the catheter to a particular time in the cyclic physiological signal such that the location of the catheter is detected at the same point in time with respect to the physiological signal for each cycle; identifying landmarks within the region based upon a sensed physiological condition; registering a three-dimensional heart model with the identified landmarks to provide a patient specific three-dimensional heart model; and providing a statistical atlas operable to define at least a portion of the three-dimensional heart model; wherein registering a three-dimensional heart model with the identified landmarks includes registering the statistical atlas to the patient specific three-dimensional heart model. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40)

41. A method of navigating a catheter in a patient via a display and tracking system, comprising:
-
collecting image data of a region of the patient; accessing a pre-acquired model formed with statistical data of the region of a subject other than the patient; registering the pre-acquired model to the collected image data of the region of the patient at least in part by matching points in the accessed pre-acquired model with points in the collected image data; tracking the catheter relative to the region of the patient; and displaying an icon representative of the catheter relative to the collected image data that is registered to the pre-acquired model. - View Dependent Claims (42, 43, 44)
