Simultaneous Mr-Excitation of Multiple Nuclei with a Single Rf Amplifier

摘要

A medical imaging system ( 2 ) excites multiple nuclei through a single RF amplifier ( 24 ). The medical imaging system ( 2 ) includes a magnet ( 10 ) that generates a main magnetic field (Bo) in an examination region. A gradient coil ( 14 ) superimposes magnetic field gradients (G) on the main magnetic field Bo. At least one transmitter ( 28 ) generates multi-nuclei excitation pulses associated with at least two different isotopes and two different frequency spectra. The single amplifier ( 24 ) sends the multi-nuclei excitation pulses to a RF coil ( 18, 20 ) for application to the examination region.
