The probe comprises: an upper cover plate, the surface of the upper cover plate being provided with gas diffusion holes, and a metal filtering screen being provided above the gas diffusion holes; a lower cover plate located under the upper cover plate and detachably connected to the upper cover plate, and an electric wire through hole being formed in the bottom of the lower cover plate; a light path module located in an internal space defined by the upper cover plate and the lower cover plate and used for modulating the laser emitter and collecting a detection signal; and an electronic processing circuit board located in the internal space defined by the upper cover plate and the lower cover plate, located below the light path module, electrically connected to the light path module, and used for processing the signal generated from the light path module.

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.

Abstract: A magnetic resonance system, a transmission apparatus, and a transmission method is provided. The transmission method includes: generating and outputting a pulse signal by a signal output unit, amplifying the pulse signal by a radio-frequency power amplifier, and transferring, by an impedance matching circuit, the signal amplified by the radio-frequency power amplifier to a transmit coil of the magnetic resonance system; and determining a first phase among a plurality of adjustable phases that enables a performance indicator of the radio-frequency power amplifier to meet a first condition, and adjusting an output impedance of the impedance matching circuit at least according to the first phase.
