“…The possibility of using short-pulse lasers has led to the development of alternative methods of laser-induced treatment and to new difficulties in modeling processes in biological tissues, especially when nanoparticles are embedded in tissues (Jaunich et al, 2008;Muthukumaran and Mishra, 2008;Liu and Hsu, 2008;Bhuvaneswari and Wu, 2009;Ruan et al, 2010;Mishra et al, 2012;Zhang et al, 2013;Browmik et al, 2014;Randrianalisoa et al, 2014;Yakovlev et al, 2019). At the same time, a number of methodological issues that arise even with the use of continuous-wave lasers and without nanoparticles remain insufficiently clarified.…”

The most interesting, but insufficiently known results obtained by the author in modeling laser-induced hyperthermia of human tumors are discussed. It is important that the traditional equation for the local bio-heat transfer does not work in superficial layers of the body. It is shown also that the classical Arrhenius law is not applicable to living tissues because of the tissue regeneration due to oxygen supplied by the arterial blood. The latter is one of the main reasons of the suggested strategy of laser heating of tumors in the therapeutic window of semitransparency when the tumor asphyxiation is considered as one of important weapons against the cancer. The other advantages of this advanced strategy of a soft thermal treatment (in few of sessions), which is painless for patients, are discussed as well. Some features of modeling various heat transfer modes are also considered. The best choice between the simplest differential models for the radiative transfer calculations is dependent of the particular problem statement. The known finite-difference or finite element algorithms can be preferable in solving transient heat transfer problems. As a rule, it depends on the shape of the computational region. It is expected that this paper will help the colleagues to overcome some typical weaknesses of computational modeling of infrared photothermal treatment of superficial tumors.

“…The problem of a transient radiative transfer has been addressed in numerous investigations, especially in the last decade [18][19][20][21][22][23][24][25][26][27][28][29][30][31][32]. However, only few of these studies were concerned with biomedical applications.…”

Transient radiative transfer effects are pertinent to thermal treatment of superficial cancer via short-pulsed laser irradiation. The transient effects become particularly important due to relatively strong scattering and long attenuation path of radiation in human tissues in the therapeutic window until the complete absorption. Our analysis is based on transport approximation for scattering phase function and the Monte Carlo method for radiative transfer. One-dimensional radiative transfer problem is considered, which was proved to be applicable for simulation of heat transfer and thermal destruction of tumors in superficial human tissues in the case of indirect heating strategy. A series of Monte Carlo calculations enables us to find the threshold of the steady-state approach applicability. In the biomedical problem under consideration, the steady-state solution for absorbed radiation power is sufficiently accurate at duration of laser pulse more than about 10 ps. The calculations for human tissues with embedded gold nanoshells, which are used to increase the local volumetric absorption of the radiation, showed that overheating of the nanoshells with respect to the ambient biological tissue is strongly dependent of the laser pulse duration. This effect is quantified for short pulses by solving the unsteady radiative transfer problem.
