Here we describe a system of monohedral permanent magnets that make up a part of a device for uni-lateral portable NMR. The magnets generate a focused region with a uniform magnetic field, located several centimeters above the surface of the magnet. The surface of the magnet is placed on the posterior portion of the chest allowing the homogeneous field region to be located inside the lung. The device can measure a proton signal, as well as that of hyperpolarized Xe, in order to measure lung density and ventilation respectively.
