Large-aperture Nuclear Magnetic Resonance Imaging Analyzer

Large-aperture Nuclear Magnetic Resonance Imaging Analyzer

Image signal-to-noise ratio ≥ 20dB, image distortion ≤ 5%, image uniformity ≥ 70%; Magnetic resonance analysis software includes multiple pulse sequences such as Fid, SE, IR, SR, CPMG, IR-CPMG, SR-CPMG, SFG-CPMG. The shortest CPMG echo time for a 1-inch probe is ≤ 60μs, with the probe featuring low heating technology; the shortest CPMG echo time for a 4-inch probe is ≤ 250μs, also with low heating technology. The device is equipped with RF technology to shorten probe dead time and capture shorter relaxation signals; it can be matched with low-temperature high-pressure modules (-30°C, 40MPa), high-temperature high-pressure modules (150°C, 80MPa), rock triaxial damage systems (axial pressure 100MPa), and other modules, supporting customer customization needs.
