Superconductive magnet system with low and high temperature superconductors

摘要

A magnet structure particularly suitable for partial human body magnetic resonance imaging. A superconductive magnet assembly consisting of a plurality of axially symmetric low and/or high temperature superconductors through which currents are induced to flow. One or more of the superconductors are at locations close to the region of homogeneous field. Geometry and locations of the superconductors and current through the superconductors are such that a substantially homogenous magnetic field results in a selected region.
