Software product for three-dimensional cardiac imaging using ultrasound contour reconstruction
First Claim
1. A computer software product for modeling of an anatomical structure, the product comprising a computer-readable medium, in which program instructions are stored, which instructions, when read by the computer, cause the computer to acquire a plurality of ultrasonic images of the anatomical structure using an ultrasonic sensor, at a respective plurality of spatial positions of the ultrasonic sensor, to measure location and orientation coordinates of the ultrasonic sensor at each of the plurality of spatial positions, to receive a manual input marking contours-of-interest that refer to features of the anatomical structure in one or more of the ultrasonic images and to construct a 3-D model of the anatomical structure based on the contours-of-interest and on the measured location and orientation coordinates.

Abstract
A computer software product for modeling of an anatomical structure includes a computer-readable medium, in which program instructions are stored, and which instructions, when read by the computer, cause the computer to acquire a plurality of ultrasonic images of the anatomical structure using an ultrasonic sensor, at a respective plurality of spatial positions of the ultrasonic sensor in order to measure location and orientation coordinates of the ultrasonic sensor at each of the plurality of spatial positions. The software product is used to receive a manual input marking contours-of-interest that refer to features of the anatomical structure in one or more of the ultrasonic images and to construct a 3-D model of the anatomical structure based on the contours-of-interest and on the measured location and orientation coordinates.
