Low-field unilateral nuclear magnetic resonance equipment for superficial skin imaging

Abstract

The invention relates to low-field unilateral nuclear magnetic resonance equipment for superficial skin imaging, and belongs to the technical field of nuclear magnetic resonance detection. The equipment comprises a unilateral permanent magnet structure, a radio frequency coil, a gradient coil and a radio frequency shield, and is characterized in that the unilateral permanent magnet structure is used for generating a static magnetic field; the radio frequency coil is used for generating an excitation radio frequency magnetic field which is orthogonal with a main magnetic field, and detecting echo signals generated by a measured sample arranged at the upper side of the unilateral permanent magnet structure; and the gradient coil is used for performing spatial coding. The low-field unilateral nuclear magnetic resonance equipment has the advantages of simple structure, small volume, light weight, reliable performance, ability of realizing signal measurement of nuclear magnetic resonance and superficial imaging, ability of being convenient for field non-invasive detection, and the like.

Description

technical field [0001] The invention belongs to the technical field of nuclear magnetic resonance detection, and relates to a low-field single-sided nuclear magnetic resonance device used for shallow skin imaging. Background technique [0002] In recent years, portable single-sided nuclear magnetic resonance technology has been widely used in food analysis and quality control, material science, geophysics and other fields. Its structure is open, its volume is small, and it is easy to move. It can perform non-destructive testing on objects at any position and from any angle. At the same time, it uses permanent magnets to provide the main magnetic field, which is low in price and low in energy consumption. The information given includes relaxation time T1, T2 imaging, diffusion coefficient D, and even chemical shift.

AI Technical Summary

Problems solved by technology

Skin burns are a common disease, but currently there are no good testing equipment and methods for judging the degree of skin burns and diagnosing skin recovery after burns, mainly based on the subjective judgment of doctors and the personal experience of patients. This method is relatively rough , Subjective, easy to cause misjudgment of burn depth and wrong treatment plan

Existing medical diagnostic methods, such as computed tomography (CT) and magnetic resonance imaging (MRI), can image human skin, but they are too bulky to perform clinical real-time monitoring and measurement.
