Web15 aug. 2024 · The mice MRI system normally requires the central magnetic field of 3 T or above with a magnetic field homogeneity better than 10 ppm in a 50 mm diameter spherical volume (DSV) to obtain high-quality images for short relaxation time. The superconducting magnet is indispensable to generate a high magnetic field. Web24 jan. 2024 · The enviro-Steel magnetic steel shielding is used to reduce the spread of the 0.5mT (5 Gauss) line of the magnetic field to protect sensitive medical equipment and minimise the risk to people with pacemakers and implants. If the proposed location of the magnet allows the Gauss line to spread outside the room this can have serious … rmv customer contact us
