METHOD FOR TRANSFORMING HEAD SURFACE COORDINATES TO BRAIN SURFACE COORDINATES AND TRANSCRANIAL BRAIN FUNCTION MEASURING/STIMULATING METHOD USING THE TRANSFORMATION DATA

摘要

Data collected by a transcranial brain function measuring/stimulating method is accurately projected and displayed onto a brain surface. If there is no three-dimensional head image, data is projected and displayed onto the brain surface of a reference brain. The head surface coordinates are transformed to the brain surface coordinates of the brain surface directly under the head surface by, e.g., a minimum distance search method The coordinates of a projected point on the brain surface of the head surface and the probability distribution are determined for a reference brain normalized with data on subjects.
