Abstract

See full text

Provided in an embodiment of the present application are a magnetic resonance imaging system and a transmission apparatus and a transmission method. The method comprises: generating and outputting a pulse signal by a transmission controller; amplifying the pulse signal by a radio-frequency amplifier; transmitting, by a signal processor, the signal amplified by the radio-frequency amplifier to a transmit coil of the magnetic resonance imaging system; and generating frequency offset lookup information for bandwidth compensation of the entire transmission apparatus according to bandwidth data of the transmission controller, the radio-frequency amplifier, and the signal processor; wherein the frequency offset lookup information is used to control the transmission controller to generate output power. Thus, the method can use the frequency offset lookup information to perform digital pre-distortion processing of a power amplifier, and can also improve the bandwidth performance of the entire transmission apparatus and improve the quality of magnetic resonance images.
