An Intelligent Magnetic Resonance Whole-body Imaging Superconducting Magnet System

Abstract

An intelligent magnetic resonance whole-body imaging superconducting magnet system, comprising: a vacuum container, a main magnetic field superconducting coil is provided in the radially inner space in the vacuum container, and a shielding magnetic field superconducting coil is provided in the radially outer space in the vacuum container, A heat pipe gas storage tank is placed in the vacant area between the main magnetic field superconducting coil and the shielding magnetic field superconducting coil; the helium liquid storage box communicates with the gas storage tank of the liquid storage box, and at the same time connects the main magnetic field superconducting coil or the The magnetic field shielding superconducting coil, the helium self-excited oscillating heat pipe is also connected to the heat pipe gas storage tank; the refrigerator is fixed on the vacuum container through the cold head automatic plug-in assembly; the first-stage cold head of the refrigerator is closely connected with the heat radiation shield assembly In contact, the secondary cold head of the refrigerator is in close contact with the helium liquid storage box. The invention overcomes the problems of low cooling performance of the existing superconducting magnet system, rapid temperature loss of the magnet due to excessive heat leakage once the refrigerator stops working, and complex maintenance of the superconducting magnet system and poor reliability.

Description

technical field [0001] The invention relates to a superconducting magnet system used in the field of magnetic resonance whole-body imaging, in particular to an intelligent superconducting magnetic resonance system. Background technique [0002] Magnetic resonance imaging (MRI) uses the magnetic resonance phenomenon of atomic nuclei (such as protons) under a uniform magnetic field to image different tissues and organs in the human body, thereby realizing medical diagnosis and other functions. The signal-to-noise ratio of magnetic resonance imaging is proportional to the magnetic field strength, so the higher the field strength, the better the clarity of magnetic resonance imaging, which is more conducive to doctors to make accurate diagnoses and realize complex imaging functions. At present, the mainstream of domestic and foreign markets is 1.5T magnetic resonance imaging system, and the imaging system with 3T or even higher magnetic field has a faster development speed.
