COLORING ELECTROANATOMICAL MAPS TO INDICATE ULTRASOUND DATA ACQUISITION
First Claim
1. A computer-assisted method for producing images of a living subject, comprising the steps of:
- displaying a three-dimensional model of a surface of a structure in a body of said subject;
acquiring a sequence of two-dimensional images of at least a portion of said structure, said two-dimensional images having respective image planes; and
while acquiring said sequence, marking said three-dimensional model to show respective intersections of said image planes with said surface.

Abstract
During acquisition of ultrasound data in a medical imaging procedure, three-dimensional model of a structure being imaged, e.g., an electroanatomical map, is co-displayed and visually marked, to indicate progress of data acquisition. The plane of intersection successive two-dimensional images are marked on the as a line or colored region on the three-dimensional model. This display enables the operator to determine regions where sufficient data have been captured, and guides the operator to areas where additional data collection is still needed. Various color schemes are used to indicate the relative sufficiency of data collection.

14. A computer-assisted method for producing images of a living subject, comprising the steps of:
-
introducing a probe into a heart of said subject, said probe having a location sensor; with said probe determining respective spatial coordinates of different locations in said heart to define a three-dimensional space; generating a functional model comprising a three-dimensional map of said heart comprising functional information relating to said heart measured at multiple points of said heart; acquiring an ultrasound image of a portion of said heart; registering said ultrasound image with said three-dimensional space; automatically marking a region on said map that corresponds to said portion of said heart; and displaying said ultrasound image and said map, wherein said region is shown in a pseudocolor. - View Dependent Claims (15, 16, 17, 18)
