Abstract
The invention relates to a method for determining the effect of magnetic stimulation on human brain. According to the method, the stimulation dose is determined in different parts of the brain by summing cumulatively the electric field strength generated by the individual stimulus pulses. According to the invention, the position and alignment of a magnetic stimulation coil () is determined separately for each applied stimulus pulse in three dimensions relative to the head (), the number, repetition rate and intensity generated by the magnetic stimulation coil () are measured separately for each pulse, the coordinate data of the brain are determined substantially unambiguously in the same coordinate system with the magnetic stimulation coil () on the basis of information obtained from other kind of measurement, such as a tomographic scan or, e.g., a statistic database collected from a large number of patients, and the cumulative dose of electromagnetic radiation imposed on said desired point in the brain is determined on the basis of the location data available from the brain and the measurement data computed for the cumulative effect of the electromagnetic field evoked by said magnetic stimulation coil ().
