Abstract:
In this paper we describe a technique for dynamic three-dimensional (3D) reconstruction of the left ventricle, using boundaries from multiple two-dimensional (2D) echocardiographic views. We use a geometric model of the left ventricle and anatomical landmarks to relate the recorded views to positions within the model. The reconstruction is step-wise refined by replacing model data with recorded contour data.
