N2 - An image processing method is proposed, which compensates for cross-planar motion of myocardium based on 3-D analysis of multi-planar, magnetically tagged MR images of the heart. The spatial modulation of magnetization (SPAMM) technique is applied for this purpose. In order to illustrate the developed method, a sample study was processed and differences between the traditional approach and the proposed technique were evaluated. Tracking was performed on tips of the SPAMM-induced tags at the endocardium, and the motion of the associated tissue was evaluated. It is shown that the accuracy of measuring the endocardial motion is significantly improved by compensating for the trans-plane motion.
