Trigger Delay and Saturation Time. The trigger delay (TD) sets the point within the cardiac cycle that the centre of k-space, k0, is acquired within each RR-interval . The saturation time (TS) determines the time between the saturation pulse and the centre of k-space, thereby controlling the T1-weighted contrast of the image for a particular image slice.
