Heat transfer in living tissue and simulation of temperature fields in tissue during hyperthermia treatment and thermal therapy of tumors
Abstract: The talk, first, is devoted to the fundamental problems in the description of transport phenomena in living tissue regarded as an active fractal medium and, second, presents an introduction to the models and approaches used in modeling temperature distribution during hyperthermia treatment or thermal therapy of tumors.
From the standpoint of transport phenomena the following two features make living tissue distinctive. The former is that blood flowing through the vessel system forms a fast transport network of fractal (multiscale) structure, which endows, for example, heat transfer in living tissue with anomalous properties. The latter is its active behavior. Namely, due to the living tissue response, for example, to local strong heating the heat transfer in it becomes an essentially nonlinear process. In particular, the following specific aspects will be concerned:
properties of heat and
mass transfer caused by blood flow via the vascular
· mechanism of tissue self-regulation under local heating;
· effects of the tissue response on heat diffusion;
· main bioheat transfer models and simulation of temperature field in living tissue with tumor under local strong heating;
· dynamics of necrosis growth induced by absorption of laser irradiation.
Besides some prospects and open problems in physics of bioheat transfer, in particular,
- nonlocal effects of heat transfer in living tissue under strong heating,
- non-diffusive heat propagation in cellular tissue under local strong heating
will be discussed.
