Cardiac Triggering

Under construction

More details coming soon.

To enable myocardial T1 and T2 mapping with MRF, the acquisition is typically split into multiple acquisition windows¹. Ideally, these acquisition windows are placed in the exact same cardiac phase so that the resulting parametric maps don't show any motion corruption. In order to allow the flexible placement of the acquisition window depending on the subject's heart rate, we are using Pulseq's new soft delay feature.
