Initial demonstration images, 1H and 3He, have been obtained from a very-low magnetic field MRI system. The system is designed to provide open-access human-scale imaging at or below 50 gauss, permitting free variation of subject orientation within the applied field. The magnetic field is created by an optimized 4-coil system, and features three-dimensional planar gradients which do not inhibit subject access. Attention to noise reduction has permitted 1H images from water phantoms to be obtained. 3He images with high sensitivity indicate the potential for high-quality imaging of inhaled laser-polarized gases in human subjects.
