Figure 1. An example of a gradient echo sequence timing diagram. Red dotted lines mark possible block boundaries. RF pulses and ADC events are not allowed to cross block boundaries; however, gradients are not forced to 0 at the boundaries (see blue circles), allowing for efficient gradient wave forms as needed for the fast sequences. Block arrows on the top mark possible position update points; filled ones correspond to the currently implemented option.
