resonant frequency. MRI Core 12 PULSE SEQUENCE CONTROLLER The pulse sequence controller is responsible for the timing and performance of each system component. The pulse sequence controller dictates when and how much gradient power is needed to vary the magnetic field and spatially encode the MR signal.
