<P>PROBLEM TO BE SOLVED: To rapidly calculate and display the disease site in the brain of the brain disease patient during examination or operation, and to enhance the precision of diagnosis and operation. <P>SOLUTION: The position of equivalent intracerebral current dipole is calculated with intracerebral current dipole by using a brain wave information which is recorded with a brain wave electrode arranged on the head surface of the patient, or a deep electrode inserted in the brain, or a subdural electrode, and the information which is converted the electrode position of a brain wave recording into numerical values for three-dimensional coordinates with X-ray CT and MRI image information. Furthermore, the apparatus is composed of a computer which overwrites the position of the intracerebral equivalent current dipole as the result of calculation and the size and the direction of generating voltage on X-ray CT and MRI images, and a device for displaying the positions and the like of the overwritten equivalent intracerebral current dipole. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
