Abstract:
An open architecture superconducting platform magnet suitable for use in magnetic resonance imaging interventional procedures comprising:a shaped yoke assembly of magnetic material; a patient support to position a patient with open accessible space spaced from said yoke; a superconducting coil assembly contiguous to said yoke with its axis beneath said patient support; said yoke including portions which are shaped to provide a homogeneous magnetic field in an imaging region above said patient support; said shaped yoke assembly positioned below and to the side of said patient support while leaving unobstructed the space above said patient support to provide said open accessible space; and said superconducting coil assembly and magnetic members shaped and positioned to provide an imaging volume magnetic field above the patient support which is tapered in cross section with the smaller cross section of said tapered cross section being remote from said magnetic coil. said accessible space above said patient support facilitating said interventional procedures.
