Method for measuring myocardial motion and the like

Abstract

A method of magnetic resonance imaging of myocardial motion includes positioning a portion of a patient such as a patient's heart within a main magnetic field and employing a plurality of RF signals to establish a plurality of parallel plane tags through the portion. In imaging heart motion, a first minimum spacing between adjacent tags is employed in a region where the tags will decrease their separation over systole and a second initial tag separation will be employed for portions wherein the tags increase their separation over systole. The method facilitates simultaneous imaging of both such motions. Fourier coefficients may be employed in establishing the generally parallel tags which may be positioned generally symmetrically about a central tag.
