Figure 1

Example of magnitude (A, B) and phase (C, D) images reconstructed with the new reconstruction and for data acquired at systole (A, C) and diastole (B, D) periods for the same subject. E) Plot of left ventricular outflow tract (LVOT) and mitral valve inflow (MVI) velocity curves. The start and end of the S, E and A waves are delineated by the horizontal axis intercepts of tangent lines drawn on the ascending (+ superscript) and descending (- superscript) slopes of the respective waves. These are then used to calculate: IRT - isovolumic relaxation time, ICT - isovolumic contraction time and ET - ejectiontime as shown.
