Compact peripheral component interconnect (cPCI)-based spectrometer for magnetic resonance imaging system and magnetic resonance imaging system

Abstract

The invention discloses a compact peripheral component interconnect (cPCI)-based spectrometer for a magnetic resonance imaging system and the magnetic resonance imaging system. The spectrometer comprises a cPCI mainboard, a sequence analysis and execution module and a functional module, wherein the cPCI mainboard provides a sequence program to be executed for the sequence analysis and execution module; the sequence analysis and execution module analyzes the sequence program so as to form a sequence execution time sequence and a sequence instruction; and the functional module comprises a radio frequency output module, a gradient output module and a data acquisition module, and the sequence analysis and execution module controls the radio frequency output module, the gradient output module and the data acquisition module to execute corresponding sequence instructions respectively according to the sequence execution time sequence. By combination of a cPCI architecture and a spectrometer for the magnetic resonance imaging system, the spectrometer has higher stability, anti-jamming performance, corrosion resistance and expandability, so that the spectrometer is applicable to the medical equipment field which has higher requirements on the stability and electromagnetic compatibility.

Description

technical field [0001] The invention relates to the field of magnetic resonance imaging and detection, in particular to a cPCI-based spectrometer for a magnetic resonance imaging system and a magnetic resonance imaging system with the spectrometer. Background technique [0002] Magnetic resonance (magnetic resonance, MR) is a constant magnetic field generated by a magnetic resonance magnet. Through the control of the radio frequency system and the gradient system, the radio frequency system is used to excite and receive magnetic resonance signals, and the gradient magnetic field is used to excite the sample layer and space. encoding to obtain a tomographic imaging method with spatial position information.
