Therapy apparatus for generating magnetic field of electromagnetic field variable in time by a sequence of current pulses.

摘要

Therapy apparatus magnetic field, having a pulse generator (10) with a final phase excitation current and a field coil (4) connected with the final phase of excitation current for generating an electromagnetic field, which It is acting on a body region to be treated, wherein the pulse generator (10) is configured with the final phase excitation current so generated in the field coil (4) a current flow which is constituted by a sequence of several repetitions of a pulse sequence, wherein the pulse sequence is composed of several current pulses of the same basic shape which can have a variable width and a width variable pulse and can be spaced each other by pauses of variable pulses, characterized in that with each current pulse the absolute value of the current is increased from an initial value and beginning with a prim er gradient, wherein the gradient is always raised to a second gradient and then falls continuously to a third gradient, after which the absolute value of the current falls suddenly again to the initial value.
