Title:
NON-INVASIVE QUANTITATIVE NUCLEAR MAGNETIC RESONANCE DETECTION SYSTEM FOR ORGANS
Document Type and Number:
WIPO Patent Application WO/2022/205573
Kind Code:
A1
Abstract:
The present invention relates to the technical field of nuclear magnetic resonance (NMR), and disclosed is a non-invasive quantitative NMR detection system for organs. The present invention may provide a novel NMR measurement system that may achieve the effect of regional selective excitation, that is, by arranging parallel radio frequency (RF) field shielding plates in a peripheral region of a main RF coil of an RF subsystem, some RF fields of the main RF coil may be shielded, so as to achieve the purpose of not exciting useless signals such as body surface fat, achieving the effect of regional selective excitation, and solving the problem of inaccurate fat detection due to unsatisfactory excitation regions being present in current unilateral magnet NMR systems.
