Abstract

The invention provides a magnetic resonance spectrometer, the spectrometer comprises: a scan and reconstruction computer and a control scanning element, wherein the control scanning element comprises a scan resonance engine, a digital excitation engine, a scan sequential control module and a digital signal processing module; the scan resonance engine is connected with the scan and reconstruction computer to generate a scan sequential control subevent, a digital excitation subevent and a digital signal processing subevent, the subevents are respectively sent to the digital excitation engine, the digital signal processing module and the scan sequential control module; the digital excitation engine is connected with a gradient amplifier and a radio-frequency amplifier to generate a gradient waveform signal and a radio-frequency waveform signal; the digital signal processing module is separately connected with a digital radio-frequency receiving unit and the scan and reconstruction computer to receive a magnetic resonance imaging signal and transmit the signal to the scan and reconstruction computer for image reconstruction. The magnetic resonance spectrometer provided by the invention improves the magnetic resonance image quality.

Description

technical field [0001] The present application relates to medical equipment technology, in particular to a magnetic resonance spectrometer. Background technique [0002] Magnetic resonance (magnetic resonance, MR) uses the constant magnetic field generated by the magnet in the magnetic resonance system. Through the control of the radio frequency system and the gradient system, the radio frequency system excites and receives the magnetic resonance signal, and uses the gradient magnetic field to excite and select the sample. Layer and spatial coding to obtain a tomographic imaging method with spatial position information. [0003] A magnetic resonance spectrometer is a device used in magnetic resonance imaging methods, which is used to generate radio frequency waveforms used by radio frequency systems, gradient waveforms used by gradient systems, and can receive magnetic resonance signals. In related technologies, the spectrometer is usually a centralized device placed in the...
