Abstract :
A new algorithm for simultaneously identifying the space or temperature dependent conductivity K, blood perfusion rate IW b, metabolic rate q m, and thermal diffusibility α in Pennes´ equation is postulated. The obtained over determined equations are solved by way of Householder´s transformation. The validity of the method is tested through an example.
