Electrosurgery is based on the application of electric current on biological tissues as a means of cutting, coagulating, desiccating and fulgurating tissue. This multidisciplinary project is concentrated on the development of a software package for tri-dimensional simulation of various electrosurgical interventions. Apart from scientific importance, the result could become a pillar for the planning of electrosurgical procedures, a faster and easier post-surgical recovery and equipment optimization.
