Method for producing an off-center image using an EPI pulse sequence
An off-center NMR image is produced using an EPI pulse sequence. The offset along the readout gradient axis is achieved by shifting the frequency of an RF reference signal used to demodulate the received NMR echo signals. Phase errors produced by the NMR system and by the shifts in reference signal frequency are corrected in "real time" by also shifting the phase of the RF reference signal.
