Abstract:

NOVELTY - The magnetic field generating method involves using two pairs of coils (1,2) in which current flows in the same direction and sense to generate magnetic fields of high uniformity within an object examined. The coil pairs have the same radiuses (R1,R2). USE - Magnetic field generating method for magnetic resonance tomography. ADVANTAGE - Ensures simple generation of magnetic field of high uniformity at reduced power indispensable for operating the tomograph. Enables unambiguous establishing of all parameters which are indispensable for the design and manufacture of generating and compensating coils. Enables significant reductions of operating costs e.g. lower costs of shielding, lower values of current for generating higher values of magnetic fields, small sizes enabling easy access to the inside of the coil system, transverse, axial access to the uniform field region.
DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a magnetic field generating system.
DESCRIPTION OF DRAWING(S) - The drawing shows the explanatory view of a coil geometry
