Abstract: A radio-frequency power amplification module for a magnetic resonance system and an imaging method are provided. The radio-frequency power amplification module includes: a power synthesizer, a main amplifier, and an auxiliary amplifier, output ends of the main amplifier and the auxiliary amplifier being both connected to a power synthesis unit; and a controller. The controller is configured to output a control signal according to a required radio-frequency transmission parameter or a scan parameter corresponding to the radio-frequency transmission parameter, so as to adjust a control parameter of the auxiliary amplifier. The radio-frequency power amplification module has high efficiency.
