3-D heart image reconstructed from MRI data.

The gated MRI method gives us several sets of cross-sectional images on transverse, coronal, and sagittal planes of the heart in a cardiac cycle. In this paper, a method to reconstruct 3-D shapes of each part of the heart (i.e., left ventricle, left atrium, right ventricle, right atrium, aorta, and pulmonary artery), in a voxel space using these sets of cross-sectional images is proposed. The whole heart image composed of these six parts properly put together can be superimposed on the original cross-sectional images for display purposes.
