Intracardiac echocardiography image reconstruction in combination with position tracking system
First Claim
1. A tracking system comprising:
- an imaging probe configured to travel through an imaged anatomy, the imaging probe operable to acquire real-time, three-dimensional (3D), image data of an imaged anatomy, the imaging probe configured to provide the 3D image data to an imaging system;
an input configured to receive, from the imaging system, a 3D model of a portion of the imaged anatomy, the 3D model being generated based on the 3D image data;
a tracking module including an electromagnetic tracking element integrated with the imaging probe to obtain real-time tracking information representative of a position of the imaging probe, the tracking module configured to selectively track the imaging probe using the tracking information;
an electrophysiologv (EP) input configured to receive electroanatomical information from an EP system; and
a registration module configured to map the electroanatomical information onto the 3D model based on the tracking information to form a color-coded map of the portion of the imaged anatomy.

Abstract
A system and method to display a four-dimensional (4D) model of an imaged anatomy is provided. The system comprises a controller, and an imaging system including an imaging probe in communication with the controller. The imaging probe can acquire generally real-time, 3D image data relative to a direction of image acquisition along an imaging plane. The system also includes a tracking system in communication with the controller. The tracking system includes at least one tracking element integrated with the imaging probe. The system is operable to process the generally real-time, 3D image data acquired by the imaging probe relative to generally real-time tracking information acquired by the tracking system so as to display the 4D model of the imaged anatomy.

22. A method of tracking a portion of an imaged anatomy, the method comprising:
-
acquiring real-time three-dimensional (3D) image data of an imaged anatomy with an imaging probe traveling through an imaged subject; generating a 3D model of a portion of the imaged anatomy based on the 3D image data; obtaining real-time tracking information in connection with a position of the imaging probe; selectively tracking the imaging probe using the tracking information; receiving electroanatomical information from an EP system; and mapping the electroanatomical information onto the 3D model based on the tracking information to form a color-coded map of the portion of the imaged anatomy. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29)
