Abstract
Embodiments of the present application provide a magnetic resonance system and a transmission apparatus, a transmission method, and a pre-scanning method. The apparatus includes: a signal output unit used to generate and output a pulse signal; a radio-frequency amplifier used to amplify the pulse signal; a signal processing unit used to transmit, to a transmit coil of the magnetic resonance system, the signal amplified by the radio-frequency amplifier, receive and adjust a phase of the feedback signal, and output the phase-adjusted feedback signal to the signal output unit; and a determination unit used to acquire amplitude values of the feedback signal at different phases, and determine a forward power and/or a reverse power according to the amplitude values of the feedback signal at the different phases.
