Problems solved by technology

Since the helium pressure is still increasing slowly, even if the helium compressor has stopped working, it is impossible to directly find that the cold head has failed, and the cold head cannot be replaced in time, which may cause damage to the superconducting magnetic resonance imaging system

Abstract

The invention discloses a method of monitoring the working state of a cold head of a magnetic resonance imaging system. The method comprises steps: cold head sound signals collected during a cold headworking period by a sound collecting device on the magnetic resonance imaging system are received; the cold head sound signals are processed, and calculation of a spectrum of the cold head sound signals is included; and the spectrum is inputted to a convolutional neural network, and based on the output of the convolutional neural network, the working state of the cold head is judged.

Description

technical field [0001] The present invention relates to the field of medical imaging, in particular to a monitoring method and a monitoring system for the working state of a magnetic resonance imaging system cold head, a cloud-based monitoring method and a monitoring system for the working state of a magnetic resonance imaging system cold head, and a method for executing the described A computer-readable storage medium for a method. Background technique [0002] The magnetic resonance imaging system has been widely used in the field of medical diagnosis. Its basic principle is to use a magnet to generate a uniform strong magnetic field. With the cooperation of a specific gradient field generated by a gradient coil, the hydrogen atoms in the body of the diagnostic object are polarized, and then radio frequency The coil emits radio frequency pulses to excite the hydrogen nuclei, causing nuclear resonance and absorbing energy. After the radio frequency pulse is stopped, the hy...
