ABSTRACT:
An ultrasonic transducer acquires a series of ultrasound tomograms as it continuously rotates through a range of angles. When positioned in a left ventricular long axis view, serial sectional slices are acquired within 6 seconds from which a 3D image is reconstructed. The boundary of the left ventricle is identified in this 3D image using a reference database produced by a learning process that captures expert knowledge of left ventricle cavity shapes.
