Abstract

We analyze the performance of the real-time system for 3D reconstruction of cardiac structures from successive 2D B-scan ultrasound images acquired using the Tilt Echo technique, developed by Buckey et al. (1987, 1993). This system is used to evaluate cardiac performance parameters such as stroke volume and ventricular mass. The design of such a real-time system involves consideration of two features, viz. the accuracy of the 3D reconstructions generated by the system, and the timing behavior of the system. We describe the procedure to test the accuracy of the system and present results to demonstrate the accuracy of reconstruction. We analyze the timing behavior of the system based on simulations using Modechart. We verify that the system design satisfies the real-time constraints
