HCC Ultrasound Surgery Therapy Modeling

This paper describes a modeling method of the
tissue temperature evolution over time in hyperthermia. More
precisely, this approach is used to simulate the hepatocel-
lular carcinoma curative treatment by a percutaneous high
intensity ultrasound surgery. The tissue temperature evolution
over time is classically described by Pennes’ bioheat transfer
equation which is generally solved by a finite difference method.
In this paper we will present a method where the bioheat
transfer equation can be algebraically solved after a Fourier
transformation over the space coordinates. The implementation
and boundary conditions of this method will be shown and
compared with the finite difference method
