Abstract
The present invention relates to a stimulator head of a magnetic stimulator used in the stimulation of living tissue such as the human brain. Such a stimulator bead comprises a stimulator head body ( ) suited for mounting the stimulator head on the magnetic stimulator equipment, at least one coil ( ) which is connected to said stimulator head body ( ) and is designed suitable for generating a stimulating magnetic field, and conductors ( ) for passing electric current from said magnetic stimulator into any of said at least one coil ( ). According to the invention, the stimulator head includes a housing ( ) which is connected to said stimulator head body ( ) and is designed to enclose at least one air-tight space ( ) which further separates each of said at least one stimulator coil ( ) from the other parts of said housing ( ) facing the object being stimulated. Further according to the invention, each of said at least one coil ( ) is placed in said housing ( ), whereby an acoustic insulation can be attained between each of said at least one coil ( ) and the object being stimulated by virtue of bringing the pressure in said air-tight space ( ) to a substantially low level.
