Relaxation spectrum analysis method and analysis system for simulated magnetic resonance imaging based on numerical simulation technology

Abstract

The invention brings forward a relaxation spectrum analysis method and analysis system thereof for simulated magnetic resonance imaging based on numerical simulation technology. The method comprises the following steps: building a simulated sample information model; building relaxation device hardware parameters; building a measurement sequence physical model; integrating the simulated sample information model, relaxation analysis related hardware parameters and the measurement sequence physical model created in the above step in order to set up a math-physical model for magnetic resonance imaging relaxation data acquisition, simulate data acquisition algorithms and realize programs and finish simulated acquisition of original data; and performing relaxation spectrum inversion on the dataacquired by the above step in order to obtain a distribution diagram of relaxation time. The relaxation spectrum analysis system for simulated magnetic resonance imaging based on numerical simulationtechnology cannot only be extensively applied to a supporting virtual experimental training platform using magnetic-resonance imaging relaxation spectrum application technology but also be applied toself-cleaning technology principles for application personnel in the technical field of related relaxation spectrum analysis. The system can also be used for instrument development and test calibration, spectrum references of sample tests, data sources for inversion study of relaxation spectrums and the like.

Description

technical field [0001] The invention relates to the technical field of nuclear magnetic resonance, in particular to a simulation nuclear magnetic resonance relaxation spectrum analysis method and analysis system based on numerical simulation technology. Background technique [0002] At present, nuclear magnetic resonance has formed a three-legged application situation of liquid nuclear magnetic resonance, solid-state nuclear magnetic resonance and nuclear magnetic resonance imaging. However, in addition to the above-mentioned important applications in the chemical and medical fields, nuclear magnetic resonance has gradually entered the petroleum industry, rubber industry, food, agriculture, textiles, building materials, porous media and other fields to play an increasingly important role in recent years. , Gradually form a new application field of nuclear magnetic resonance analysis and testing. [0003] The field of application of NMR is very broad and is constantly expand...

AI Technical Summary

Problems solved by technology

However, the NMR relaxation spectrum analysis technology involves many NMR technology foundations, especially the sequence technology, coupled with the complexity and variability of the samples to be tested, there are many problems in the use of the instrument and the interpretation of the test data results.

These are due to the fact that practitioners in various fields do not understand the basic principles of NMR relaxation spectroscopy analysis technology, and do not have a clear grasp of the characteristics of relaxation inversion.
