| Popis: | Despi te the existence of severa/ treatments for epilepsy contrai, nearly one third of the patients still need to undergo surgery in arder to contrai the seizures. Especially in these cases, it is essentia/ to locate precisely the area responsiblefor the seizures. With the advances in technology the number of techniques to help in this diagnostic has increased dramatically as well as the resolution of the resulting images. A surge011 can now have information about brain activity from severa! exams: EEG, MRI, CT, PET and Electrocorticography (ECoG) where epidural or subdural electrodes are used to record the Electroencephalogram (EEG). Many software applications are used to analyze these data, but most of them do not provide any facility to super-impose in the sarne view information from different techniques. ln ECoG, for examp/e, it is essential for the surgeon to loca te the electrodes within the brain of the patient in arder to plan the surgery and avoid removing criticai areas. ln this paper, we present the first version of a software whose objective is to combine in the sarne application the data comingfrom ECoG, MRI and CT to provide the surgeons with a too/ that combine easily ali lhe data in the sarne visualization too/ to facilita te the interpretation of the available information as a whole. 15�� Encontro Portugu��s de Computa����o Gr��fica Visualiza����o e Processamento de Imagem 177 181 Pedro Amaral, Franscisco Sales, Jo��o Paulo Silva Cunha, Paulo Dias, and Jos�� Maria Fernandes Electrocorticography, MRI and CT data, 3D Visualization, Volume Rendering |
