Magnetic Field Camera and probe array to map a 160 mm DSV extremity MRI magnet
In the development of our new extremity MRI magnet, the choice of the metrology instruments was critical. PrecisionPrecision is how closely multiple measurements will be clustered. Also called reproducibility or repeatability. In everyday speech, often confused with... More, reliability and potential to scale-up to production were the key selection parameters, all for a 160 mm DSV! The recently launched MFC9046 from Metrolab is the only NMR-based instrument offering a multiprobe array for this DSV. Based on Pulsed NMRNuclear Magnetic Resonance. A resonance phenomenon seen when you irradiate a sample in a magnetic field with an RF field.... More technology, it achieves best in class precisionPrecision is how closely multiple measurements will be clustered. Also called reproducibility or repeatability.

We are proud of our collaboration with Metrolab and to have been the first ones to use such a small Magnetic Field Camera with 14 sensors deployed over 160 mm diameter halfmoon!
