Apparatus for treatment with magnetic fields

Abstract

An apparatus for treatment of a portion of a biological body with magnetic fields having a device adapted for producing spin resonances for treatment within a portion of the biological body to be treated. The apparatus includes a magnet for producing a magnetic field, a coil system for producing a magnetic alternating field at right angles to the magnetic field, control electronics for actuation of the magnet and the coil system adapted to produce nuclear spin resonance in at least a portion of a biological body, and a device for repeated actuation of the control electronics to produce a defined sequence of nuclear spin resonances. The sequence of nuclear spin resonances produced by the device is determined by the spin-lattice relaxation time T 1 of at least one portion of the biological body, and has a repetition rate of approximately 3T 1 .
