Problems solved by technology

Today's nuclear magnetic resonance has been widely used, but it still has a shortcoming, that is, its resolution is too low. The best nuclear magnetic resonance imager in the world now has a resolution diameter of about 0.5 mm, which cannot be detected at all. Meet the current high-end technology requirements, especially the human brain project in the United States, Europe is also following up, and my country has also implemented many 973 brain projects

Embodiment Construction

[0006] There are two forms of continuous wave and pulse Fourier transform in the nuclear magnetic resonance instrument currently used. The continuous wave magnetic focusing nuclear magnetic resonance instrument is mainly composed of a magnetic focusing magnet, a radio frequency transmitter, a detector, an amplifier and a recorder. The magnetic focusing magnet generates a more powerful magnetic field by focusing the magnetic field generated by the superconductor coil. Since the magnetic field strength is proportional to the frequency, the stronger the magnetic field, the higher the corresponding measured frequency. Higher frequency instruments have better resolution. , high sensitivity, simple and easy to analyze spectrum. The magnetic focus magnet is equipped with a scanning coil, which is used to ensure that the magnetic field generated by the magnetic focus magnet is uniform and can be continuously and accurately changed within a narrow range. The radio frequency transmitte...

Abstract

The technical field of magnetic focusing nuclear magnetic resonance belongs to the field of electromagnetics, precision instrument manufacturing, image analysis, and superconductor technology. Its main technology is to focus the strong magnetic field generated by the superconductor through the superconductor to form a more powerful magnetic field to replace the current Some magnetic fields, because the higher the magnetic field strength of nuclear magnetic resonance, the better the resolution, and the sensitivity is improved, making the spectrum simple and easy to analyze, so increasing the magnetic field strength will improve the resolution of the instrument, and improve the sensitivity, making the spectrum Simple and easy to analyze.
