Problems solved by technology

[0003] At present, the magnetic resonance imaging device uses a radio frequency coil to provide a magnetic field for magnetic resonance imaging, and the radio frequency coil will produce a low signal-to-noise ratio (SNR), which will reduce the clarity of the image obtained through the magnetic resonance imaging, thereby affecting the doctor's diagnosis effect
The SNR when using a radio frequency coil is mainly determined by the magnetic field strength and temperature, and the magnetic resonance equipment in the related art cannot provide a stable low temperature environment for the radio frequency coil

Abstract

The invention discloses a cooling device and system, and magnetic resonance equipment. The cooling device is applied to low-field magnetic resonance imaging, and is characterized by comprising: a radio frequency device provided with a radio frequency transceiving coil and a radio frequency amplifier; a first cooler which is connected with the radio frequency device and is used for reducing the temperature of the radio frequency device to a first cooling temperature; and a second cooler which is arranged in the first cooler, is connected with the radio frequency transceiving coil and the radio frequency amplifier, is used for cooling the radio frequency transceiving coil and the radio frequency amplifier to a second cooling temperature, and can provide a low-temperature environment for the radio frequency coil in magnetic resonance imaging. The signal-to-noise ratio of a signal obtained through magnetic resonance imaging is improved, a clearer and more accurate magnetic resonance imaging image is further provided, the device can be applied to low-field and ultra-low-field magnetic resonance imaging, and the signal-to-noise ratio of the obtained signal can be further improved due to the fact that the magnetic field intensity of low-field and ultra-low-field magnetic resonance is low.

Description

technical field [0001] The invention relates to the technical field of magnetic resonance imaging, in particular to a cooling device, system and magnetic resonance equipment. Background technique [0002] With the development of medical technology, Magnetic Resonance Imaging (MRI) technology is becoming more and more important. Magnetic resonance imaging is a routine procedure for diagnosing and treating various diseases and injuries. It can accurately reflect the pathological tissue conditions, enable doctors to make accurate diagnoses, and provide targeted treatment to patients based on the results of magnetic resonance imaging. [0003] At present, the magnetic resonance imaging device uses a radio frequency coil to provide a magnetic field for magnetic resonance imaging, and the radio frequency coil will produce a low signal-to-noise ratio (SNR), which will reduce the clarity of the image obtained by the magnetic resonance imaging, thereby affecting the doctor's diagnosi...
