Abstract

The embodiment of the present invention discloses a magnet pressure control device for a magnetic resonance imaging system. The magnet pressure control device includes a pressure detection unit and a control unit, wherein the pressure detection unit is used to detect the pressure inside the magnet. pressure and send a detection result to the control unit in real time; the control unit is used to receive the detection result and switch the cold head of the magnetic resonance imaging system according to the detection result.

Description

technical field [0001] The invention relates to the technical field of magnetic resonance imaging (MRI), in particular to a magnet pressure control device of a magnetic resonance imaging system. Background technique [0002] Magnetic resonance imaging (Magnetic Resonance Imaging, MRI) is a technique that uses magnetic resonance phenomena for imaging. The principle of magnetic resonance phenomenon mainly includes: atomic nuclei containing a single number of protons, such as hydrogen nuclei widely present in the human body, the protons have spin motion, just like a small magnet, and the spin axis of these small magnets has no certain rules. External magnetic field, these small magnets will be rearranged according to the magnetic force lines of the external magnetic field, specifically in two directions parallel to or antiparallel to the magnetic force lines of the external magnetic field, and the above-mentioned direction parallel to the magnetic force lines of the external ma...
