This abstract presents a 3-directional acceleration encoding strategy with optimized gradient waveforms to reduce the echo time TE considerably. The encoding strategy was successfully validated using a rotating phantom. Its feasibility for in-vivo measurements was demonstrated in a volunteer measurement of a midventricular short-axis slice of the myocardium. The directly measured acceleration data demonstrated good agreement with acceleration data obtained by calculating the derivative from velocity data measured on the same volunteer.
