| description | The invention provides a three-dimensional electroencephalogram electrode positioning method. A CT image is adopted for positioning. The method comprises the steps that S1, the CT image obtained afterelectrode implantation being acquired for registration; S2, performing binarization processing on the multilayer image obtained through registration; S3, superposing all the images containing the target electrode into a picture; S4, determining a starting coordinate and an end point coordinate of the target electrode according to the picture obtained in the step S3, and calculating an electrode site coordinate; and S5, performing spatial coordinate transformation on the electrode site coordinates obtained in the step S4, and positioning the brain region position according to the transformed coordinates. In the positioning process, only postoperative CT images are used for working, and multiple sets of image data of a patient do not need to be used; moreover, the positioning is not influenced by the obtained CT im |
