Example prospectively-accelerated BLOSM-SENSE results from rate-4 undersampled data acquired in 8 heartbeats from a volunteer (a-i) and a patient (j-r). BLOSM-SENSE reconstructed images, a displacement map, an Ecc map and segmental Ecc-time curves are shown for the volunteer and the patient. Images are shown at mid systole (MS), end systole (ES), and mid diastole (MD). Displacement and Ecc maps represent end systole (g, h, p, q). With data collected in 8 heartbeats, the images reconstructed by BLOSM-SENSE present high quality, comparable to full sampling. Displacement and strain analyses show typical systolic myocardial contraction patterns and values for the volunteer, and impaired Ecc in the septum and inferior wall in the patient
