Abstract

Using specialized cardiac catheters for image acquisition, features of the heart are readily identifiable on an ultrasound image, based on a previously generated electrical activation map of the heart. The electrical activation map is automatically registered with the ultrasound image using information obtained from position sensors in the catheters. Features identifiable on the electrical activation map, presented as points, tags, design lines, and textual identification, are projected into the plane of the ultrasound fan and overlaid on the ultrasound image, thereby clarifying the features that are visible on the latter.

First claim

What is claimed is:

1. A computer-assisted method for producing images of a heart in a living subject, comprising the steps of:
introducing a catheter into the heart, the catheter having an electrical mapping electrode, a position sensor and an ultrasound imaging sensor;
generating an electro-anatomic map from electrical data obtained by the electrical mapping electrode and the position sensor, the electro-anatomic map establishing coordinates of points in a 3D image space, the…
