Multiple resonance NMR spectroscopy using a single transmitter

摘要

An NMR imaging system comprising a transceiver module configured to couple with a magnetic resonance transmitter coil, where the transceiver module includes a first transmitter channel and a pulse programmer configured to control the transceiver module, the transceiver module generating a precession and nutation for observing rotation at multiple intervals about the carrier (“PANORAMIC”) waveform, the PANORAMIC waveform configured to produce nuclear polarization. The PANORAMIC waveform may a single-banded PANORAMIC waveform or a multiple-banded PANORAMIC waveform. A method of NMR spectroscopy or imaging, the method comprising: determining for a nuclear spin rotation at least one frequency interval and at least one corresponding phase; creating a PANORAMIC waveform for the at least one frequency interval and the at least one corresponding phase; and applying the PANORAMIC waveform from an amplifier output to a probe input. The PANORAMIC waveform may be a single-banded PANORAMIC waveform or a multiple-banded PANORAMIC waveform.
