Direct radiofrequency phase control in MRI by digital waveform playback at the Larmor frequency.


PURPOSE A scalable multiband and multichannel digital magnetic resonance imaging system has been developed with the goal of reducing the time needed for acquisition of a single volume of gradient-recalled echo-planar images of the brain. METHODS Transmit pulses are created by an offline computer equipped with a Pentek excitation card (PCIe model 78621… (More)
