MRI System

OPENMARK 5000 is 0.51T MRI. It’s approved by FDA and has CE mark. It adopts two-pillar magnet design with 280 degree openness and equipped with powerful RF and gradient system, together with advanced imaging technology, making it as a high-end system which is comparable to high-field MRI. Features: With the highest system stability and the highest homogeneity of the magnet field in permanent MRI Screens on both sides facilitate positioning; 280 degree two-pillar magnet design ensures stable magnet structure and facilitates interventional treatment. Active and passive shimming calibrate technology ensures the magnetic field uniformity Motor-driven patient couch makes it easier for patients to access and for positioning Powerful hardware and software platforms ensure the scan speed, image quality and make it possible for advanced imaging functions Fast scan speed eliminates motion artifact Rich scan sequences, advanced imaging technology and powerful postprocessing technology ensure image quality, extend more applications, which can fully satisfy the clinical needs Intelligent user-friendly operating system ensures you easy operation Technical Specifications: No. Technique Parameter 1 Magnet System  1.1  Magnet Type Permanent Magnet Automatic constant temperature system 1.2 Field Strength 0.51T 1.3 Magnet Shape Dual-pillar shape 1.4 Homogeneity（40cm，DSV，VRMS） ≤1.6ppm 1.5 Shim Method Active/Passive 1.6 Magnet Vertical Gap (Cover) 40cm 1.7 Magnetic Pole Dia.
