Automatic identification of intracardiac devices and structures in an intracardiac echo catheter image

Abstract

An intracardiac imaging system 10 configured to display electrode visualization elements within an intracardiac echocardiography image 12 where the electrode visualization elements represent intracardiac electrodes in close proximity to the plane of the image 12. The system 10 further allows cross sections of tissue structures embodied in intracardiac echocardiography images 12 to be modeled within a visualization, navigation, or mapping system 20 when automatically segmented to generate shell elements 36 for modifying the modeled tissue structures.

Description

[0001] Cross references to related applications [0002] This application claims the priority of U.S. Patent Application 12 / 983,013 filed on December 31, 2010, which is incorporated herein by reference as if fully stated herein. Technical field [0003] The present invention relates to medical imaging and physiological modeling, and in particular, the present invention relates to the identification and tracking of equipment and structures in an imaging or modeling mode, and the simultaneous display of those information in a separate imaging or modeling mode. Background technique [0004] It is well known that the prevalence of different imaging modalities in the medical field provides clinicians with valuable information about patient physiology. However, all imaging modes have some type of error, which introduces uncertainty into the generated image. Further limiting the application of medical images is that when the image does not contain recognizable landmarks to provide a backg...

However, the navigation electric field is not guaranteed to be uniform or isotropic, so for these geometries, distortions are often

The positioning of ICE catheters and the images they generate is further complicated by the fact that echo images often do not represent the idealized echo plane, as it has been observed that echo images often exhibit rotational and translational deviations from the ideal
