It has broad prospects in both biomedical basic research and disease-related application research. Biomedical research focused on pre drug studies can avoid the risks associated with conducting experiments on humans. Imaging techniques, especially magnetic resonance imaging, are currently one of the most effective tools in drug analysis and research. Nuclear magnetic resonance technology is a landmark analytical testing and research instrument that measures the comprehensive level of scientific research and the depth of scientific research work. It has begun to develop in China and is becoming an analytical testing and research tool for teaching, scientific research, key disciplines, and key laboratory construction.

The magnetic field strength of the 1.5T (5mm) imaging system has increased to 1 5T， Under the same external conditions and environment, the signal-to-noise ratio increases by about 0 10 times higher than the 5T system, significantly improving detection sensitivity; This instrument provides a new approach for biochemical analysis such as safety testing, medical diagnosis, and large-scale screening of biomarkers. Using a 1.5T magnet, compared to imaging equipment with a 3T field strength, the cost is lower. Compared to a 0.5T low field permanent magnet magnetic resonance imaging equipment, it has better magnetic resonance experimental results, higher magnetic field strength, stronger gradient strength, and higher spatial and temporal resolution. This enables magnetic resonance imaging to reach the level of molecular imaging, greatly expanding its applications in materials science, botany, pharmacology, toxicology, and other fields.
