Problems solved by technology

However, the traditional polarization cavity cannot be recycled, and alkali metal needs to be refilled for each test, which not only causes 3 He gas is greatly wasted and filled with alkali metal many times, which also brings great difficulties to the operation

Abstract

The invention discloses a polarization chamber system based on a hyperpolarization gas and a use method thereof. The polarization chamber system comprises three parts, wherein a first part is used for conveying alkali metal steam and a second part is used for mixing the alkali metal steam with 3He and N2 gases conveyed by a third part in a polarization chamber, polarizing in the manner of heating by a heating furnace in a magnetic field and lastly, conveying the highly polarized 3He gas into a storage bag through a capillary glass tube and a spiral filtering pipe. The system provided by the invention can overcome the defect that the traditional polarization chamber only can be used for one time; the polarization chamber system is reusable; the repeated filling of 3He and N2 gases can be realized, once alkali metal filling can be tested repeatedly and the volume of the gas filled into the polarization chamber can be accurately controlled by the intelligent control on the opening / closing of a gas flow meter and a solenoid valve, so that the gas waste is greatly reduced and the operation steps are simplified.

Description

technical field [0001] The invention relates to hyperpolarized 3 In the field of He gas magnetic resonance imaging (MRI), specifically a hyperpolarization-based 3 Polarized cavity system for He gas. Background technique [0002] With the increasingly serious air pollution, the number of patients with chronic lung diseases is increasing year by year. Higher hydrogen proton density can be used to image tissues. For the lungs, the hydrogen proton density is only one tenth of that of other tissues. Obviously, it is not suitable for lung imaging. [0003] It was found that the hyperpolarized 3 Magnetic resonance imaging (MRI) of He gas applied to the lungs can obtain high-quality images of lung organs. It is a very promising technology, which can accurately diagnose pulmonary disease, it overcomes the shortcomings of traditional magnetic resonance imaging that is difficult for lung imaging. Currently, the spin-exchange optical pumping method (SEOP) is the method to obtain hy...
