Abstract
The provided is a magnetic resonance (MR) system with spatial selectivity and a working method thereof. The MR system includes a data display and processing module, a spectrometer with at least one transmission channel, at least one power amplifier, a transmit-receive (TR) switch, a preamplifier, multiple sets of coils, and a magnet module, where when a number of transmission channels of the spectrometer is not less than a number of coils, one power amplifier is connected to the TR switch, while other power amplifiers are correspondingly connected to other coils (2, 3, 4) except for a main coil (1); when the number of the transmission channels of the spectrometer is less than the number of the coils, an output terminal of the at least one power amplifier is first connected to at least one power divider and multiple phase shifters and then connected to the coil.
