Schematic of the proposed non-ECG-triggered acquisition scheme. (a) A conventional triggered sequence. A single slice is acquired following each SR-preparation. Data collection starts following a short delay time (TI). Additional slices are acquired sequentially in consecutive cardiac phases. (b) In the non-ECG-triggered sequence, projections for all 3 slices are interleaved following each SR-preparation (total of 78 projections over 156 ms). There is no delay between the start of acquisition and the SR-preparation to enable fast T1 mapping. Data is acquired continuously for 38 seconds. The sliding-window reconstruction window includes 26 projections, matching the acquisition window, ensuring equivalent T1 weighting regardless of the location of the reconstruction window.
