Problems solved by technology

However, this setting method requires the use of a large amount of liquid helium, and my country’s liquid helium resources are short and need to be imported from abroad. Using a large amount of expensive liquid helium will lead to an increase in the price of the MRI device and increase the maintenance cost of the equipment. Limiting the application and popularization of nuclear magnetic resonance imaging equipment

Abstract

The invention discloses a coil framework which is used for fixing a superconducting coil. A liquid helium runner which is used for guiding liquid helium to cool the superconducting coil and maintain the superconducting coil to be in a superconducting state is arranged between the inner surface and the outer surface of the coil framework. The invention further provides a magnetic resonance imaging device with the coil framework; the magnetic resonance imaging device can greatly reduce the use amount of liquid helium; thus, the manufacture cost and the maintenance cost of the magnetic resonance imaging device are obviously reduced, the economic benefit of a factory is improved, and the wide application of the magnetic resonance imaging device is facilitated.

Description

technical field [0001] The invention relates to the technical fields of superconducting technology and medical equipment, in particular to a coil frame, and also relates to a nuclear magnetic resonance imaging device having the coil frame. Background technique [0002] Magnetic resonance imaging devices are widely favored by medical institutions because they can quickly obtain high-precision stereoscopic images of the internal structure of the patient's body without causing damage to the patient's body. [0003] The magnetic resonance imaging magnet is one of the key components of the nuclear magnetic resonance imaging device. In order to ensure the normal operation of the nuclear magnetic resonance imaging magnet, it is necessary to keep the superconducting coil of the magnetic resonance imaging magnet in a superconducting state, that is, a zero-resistance state. Therefore, it is necessary to make the superconducting The wire coil is in a cryogenic environment. In the prio...
