Abstract :
The temperature distributions of bone tumor therapy using scanned focused ultrasound hyperthermic system (SFUS) have been simulated. The power arrays in SFUS have been tilted, rotated, translated and convoluted to obtain the power distributions. The temperature distributions are calculated by 3-D bio-heat transfer equation (BHTE). The simulation results reveal that the overheating on bone occurs when tilt angle and rotation angle decrease, but when scanning radius toward the tumor increases
