Abstract

The invention relates to the technical field of nuclear magnetic resonance, and discloses a noninvasive quantitative nuclear magnetic resonance detection system for organs. Through the creation of the invention, a novel nuclear magnetic resonance measurement system capable of achieving a regioselective excitation effect can be provided, that is, the parallel radio frequency field shielding plates are arranged in the peripheral region of the main radio frequency coil of the radio frequency subsystem, so that a part of radio frequency field of the main radio frequency coil can be shielded; therefore, the purpose that useless signals such as body surface fat are not excited is achieved, the regioselective excitation effect is achieved, and the problem that fat detection is inaccurate due to the fact that an excitation area of a current unilateral magnet nuclear magnetic resonance system is not ideal is solved.

Description

technical field [0001] The invention belongs to the technical field of nuclear magnetic resonance, and in particular relates to a non-invasive quantitative nuclear magnetic resonance detection system for organs. Background technique [0002] In traditional medical equipment, the technical means that can be used for human organ testing (such as liver testing, etc.) mainly include ultrasonic testing, nuclear magnetic resonance testing and puncture testing. However, they each have their own limitations, such as: (a) Ultrasound detection: traditional ultrasound detection instruments can only perform qualitative measurements and cannot meet the detection requirements when the fat content is below 30%; the other type is ultrasound-based fatty liver and The main limitation of quantitative detection products for liver fibrosis is that it is easily affected by insufficient ultrasound penetration, and the success rate is low when detecting obese patients; (b) MRI detection, which can ...
