Portable MRI

Researchers at the Fraunhofer Institute have succeeded in making a small portable nuclear magnetic resonance probe, which is made and marketed by the New-Zealand based company Magritek (Technisch Weekblad, 19-07-08). The diameter of the probe is 17 cm and the earth’s magnetic field is used to generate a polarising field of 18.8 mT, allowing for applications in material science and food and nutrition (as long as the sample is maximally 7.5 cm in diameter). Magritek itself promotes the system as a hands-on teaching and training tool for MRI and NMR. They provide an interestingbrochure showing that the Terranova-MRI system allows a range of experiments using spin echo, gradient echo or projection reconstruction methods in 1D, 2D and 3D. If the system comes at a reasonable price it would be great for introductory MRI courses.
