Showing the process of scan planning and the degree of automation. Following acquisition and automated analysis of a free-breathing 4-chamber scan the DL-based software identifies both the end-systolic (A) and mid-diastolic rest (B) periods, which can be used to determine the acquisition window. The DL based software also determines the position of the coronal 3D imaging slab (in yellow) and iNAV box (in blue) to be used in the coronary MRA acquisition. The placement of the shim box and 3D imaging plane does on occasion require slight manual adjustment, especially in cases where the heart is larger than average
