Short axis magnetic resonance image showing placement of magnetic tags through the body. The intersection of the tag planes with the image give rise to parallel dark stripes.

At end-systole, the deformation of the heart can be determined from the displacement of the image stripes.

Similarly, the displacement in a long axis view from end-diastole (right) to end-systole (left) gives information missing from the short axis images.

The tags can be placed inside a geometric mathematical model of the left ventricle and used to deform the model to reconstruct the 3D deformations undergone. Here three model tags are shown at ED (right) and ES (left). Two model tags arise from a short axis image and one from a long axis image.
