Abstract:
A drive circuit of a radio-frequency (RF) transmitting coil and a magnetic resonance imaging (MRI) device are provided. According to an example, the drive circuit includes a controller, a digital-to-analogue converter (DAC) coupled with the controller, a RF amplifier coupled with the DAC, a power divider coupled with the RF amplifier, and a plurality of phase shifters respectively coupled with at least three output ports of the power divider.

Claim (Index 11):
A magnetic resonance imaging (MRI) device, comprising:\n a RF transmitting coil; and a drive circuit for the RF transmitting coil, the drive circuit comprising:\n a controller configured to output a drive signal; \n a digital to analogue converter (DAC) coupled with the controller and configured to perform D/A conversion for the drive signal to output an analogue drive signal; \n a RF amplifier coupled with the DAC and configured to amplify the analogue drive signal to obtain an amplified analogue drive signal; \n a power divider coupled with the RF amplifier and configured to generate at least three signals from the amplified analogue drive signal, wherein the power divider comprises at least three output ports each configured to output the at least three signals respectively; and \n a plurality of phase shifters coupled with the power divider, wherein each of the phase shifters is coupled with a respective output port of the at least three output ports and configured to:\n adjust a phase of the respective signal output by the respective output port to obtain a phase adjusted signal, and \n output the phase adjusted signal to a respective feed port of the RF transmitting coil.
