Cellular neural network analysis for two-dimensional bioheat transfer equation

The cellular neural network (CNN) method is applied to solve the Pennes bio heat transfer equation, and its feasibility is demonstrated. Numerical solu tions were obtained for a cellular neural network for a two-dimensional ste ady-state temperature field obtained from focused and unfocused ultrasound heat sources Transient-state temperature fields were also studied and compa red with experimental results obtained elsewhere. The cellular neural netwo rks' key features of asynchronous parallel processing, continuous-time dyna mics and local interaction enable real-time temperature field estimation fo r clinical hyperthermia.
