Abstract:
1. A method for determining a location of an electrode implanted in a subject's brain, the steps comprising: a) acquiring, with a magnetic resonance imaging (MRI) system, MR image data from the subject's brain; b) acquiring, with a computed tomography (CT) imaging system, CT image data from the subject's brain; c) reconstructing, from the acquired MR image data, MR images of the subject's brain; d) reconstructing, from the acquired CT image data, CT images of the subject's brain; e) producing from the reconstructed CT images, electrode images indicative of the location of the electrode; f) producing, from the reconstructed MR images, a model of the subject's brain by starting from a seed location within the brain and building the model outward to the surface of the brain; and g) mapping the location of the electrode onto the model of the subject's brain using the produced electrode images.
