Title:
TWO-DIMENSIONAL INVERSION MAP GENERATION METHOD AND DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/123963
Kind Code:
A1
Abstract:
A two-dimensional inversion map generation method and device, and a storage medium, which relate to the field of nuclear magnetic resonance analysis. The method comprises the following steps: performing ith direction conversion on a magnetization vector (S101), and after the ith direction conversion, executing: successively applying 90° radio frequency pulses to a sample to be tested (S102), wherein a time interval is formed between every two adjacent times the 90° radio frequency pulses are applied; and successively applying 180° radio frequency pulses to the sample once the successive application of the 90° radio frequency pulses has ended (S103), wherein a time interval is formed between every two adjacent times the 180° radio frequency pulses are applied; acquiring an echo signal between adjacent 180° radio frequency pulses to obtain ith acquired data (S104); and when i reaches a preset N value, generating a two-dimensional inversion map on the basis of first, second, ..., and Nth acquired data (S105). A relaxation signal in solid or semi-solid organic matter can be effectively detected, and more complete information is obtained.
