Generation of Myocardial Wall Surface Meshes from Segmented MRI

Figure 1

A left ventricular surface model generated by applying the marching cubes algorithm to a segmented cardiac MR image with 1.44 mm in-plane resolution and 8.0 mm slice thickness. The irregular triangles are a consequence of the voxel anisotropy. The surface mesh has pronounced terracing artifacts, and the number of triangles is directly related to the number of voxels in the image.
