Claim:
A method for manufacturing a fixture of a head for fixing magnetic field generating means, comprising the steps of: taking an image of an object along parallel planes to form a plurality of image slices of the object; adjusting a relation between a coordinate system of the image and a coordinate system that is built up by a predetermined position grasping means that grasps a position and a direction of a movable magnetic field generating means and generates position and direction data; superimposing the position and direction data with respect to the image and forming a superimposed image; fixing the position and direction data at a specific point of time in the superimposed image; recording the fixed position and direction data and the superimposed image; obtaining first coordinate data that represent a surface data of the object based on the superimposed image recorded; obtaining second coordinate data that represent the position and direction of the magnetic field generating means based on the fixed position and direction data recorded; deciding relative relationship data that represent a relative relation between the surface of object and the magnetic field generating means based on the first coordinate data and the second coordinate data; and forming the fixture that comprises a magnetic field generating means fixing part at a relative position recorded of the magnetic field generating means based on the relative relationship data, such that the fixture is attachable to the surface of the object, wherein a relative positional relation of the magnetic field generating means, represented by the position and the direction data to be fixed in the recording step with respect to the object, is a positional relation such that the highest point of an intensity of an electric current to be induced by a magnetic field to be generated by the magnetic field generating means is constantly directed onto a target spot of a diameter not more than 10 mm, which is located at a primary motor cortex within a cranium, and wherein a direction of a magnetic field to be generated by the magnetic field generating means and a location of the target spot are made into a fixed relation.
