Abstract
We describe the implementation of a field-cycling electromagnet in a whole-body clinical MRI system. A pulsed magnet is driven on during dead times of the NMR sequence and serves to increase the equilibrium magnetization induced in the patient. Signal transmission and reception occurs only during the period when the electromagnet is turned off and does not otherwise influence the data collection. Applications of the technology include image quality enhancement for low field MRI and for in vivo localized relaxation rate measurements.
