Description

Three-dimensional reconstructions (3DR) of the heart and great vessels are conventionally formed by scanning a single two-dimensional (2-D) plane, and then combining the data in this scan with data obtained from other scan planes taken at different levels. Missing data between planes are filled in by interpolation. Applications of such 3DR’s from ultrasonic, radionuclide and magnetic resonance images have yielded promising results (1). 3DR’s of the left ventricle have been obtained from cardiac ultrasonic and ultrafast computed tomographic images in our laboratory (2,3). We have also utilized the reconstructed geometries for analysis of mechanical deformation of the ventricular chamber and quantitative assessment of wall motion abnormalities in diseased states (4).

Volumetric Ultrasound: A Novel Methodology for 3D Evaluation of Cardiovascular Structure and Function
