Computational Technique. Diagram of data flow used in a hybrid finite element model implemented in Femlab/ Matlab to calculate temperature and tissue injury. The electromagnetic and thermal portions of the model are solved simultaneously in Femlab (black). The resulting temperature is used to calculate tissue injury in Matlab and the level of local blood perfusion (white). A tissue damage level of 63% corresponds to the onset of tissue necrosis and is associated with a cessation in local blood flow.
