Scope of ApplicationThe mobile 3.0T extremity magnetic resonance imaging system developed by our company offers a series of advantages over the 1.5T extremity magnetic resonance imaging system in clinical applications and scientific research. These include higher magnetic field strength, better magnetic field uniformity and stability, higher signal-to-noise ratio, clearer imaging, the ability to achieve molecular imaging technology, shorter scanning times, and faster imaging. In terms of imaging technology, the third-order active shimming meets high-end imaging requirements, enables remote medical services, and is portable and convenient, providing ease of use for military operations and training. Currently, based on the needs of the healthcare system and patients, the 3.0T extremity molecular imaging system is quickly becoming a focal point in localized precision medicine.
