Implementation of three-dimensional EEG brain mapping

The electroencephalogram (EEG) visualization software was developed contain ing two-dimensional (2D) and three-dimensional (3D) brain mapping modules. The input to the program is standard clinical individual patient data recor ded using digital EEG and magnetic resonance imaging (MRI). The software ut ilizes several techniques, such as heuristic triangulation, ray casting, Go uraud shading, and image fusion to form multimodal 3D images. The program h as been applied to the 3D visualization of various EEG signals, "cortical" EEG signals, and potential fields generated by a computer model. The develo ped program appears to operate efficiently and intuitively in PC/Windows en vironment. (C) 1999 Academic Press.
