Magneto-Hemodynamics Fluid Hyperthermia in a Tumor with Blood Perfusion

Abstract

In order to increase the drug potency and cancer treatment effectiveness, hyperthermia therapy is an adjuvant procedure in which perfused bodily tissues are heated to extreme temperatures. While certain types of hyperthermia treatments rely on thermal radiations from single-sourced electro-radiation measures, conjugating dual radiation field sources is being discussed in an effort to enhance the delivery of therapy. The thermal efficiency of a combined infrared hyperemia with nanoparticle recirculation near an applied magnetic field on subcutaneous strata of a model lesion as an ablation technique is investigated computationally in this research. To tackle the equation of linked momentum and thermal equilibrium in the blood-perfused tissue domain of a spongy fibrous tissue, an intricate Spectral relaxation method (SRM) was developed. The well-known Roseland diffusion approximation was used to define thermal diffusion regimes in the presence of external magnetic field imposition and to outline the effects of radiative flux inside the computational domain. Utilizing pore-scale porosity mechanics, the contribution of tissue sponginess was studied in a number of clinically relevant circumstances. Our findings demonstrated that magnetic field architecture could govern hemodynamic regimes at the blood-tissue interface across a significant depth of spongy lesion while permitting thermal transport across the depth of the model lesion. This parameter-indicator could be used to regulate how much hyperthermia therapy is administered to intravenously perfused tissue.

“…The non-dimensionless transformed system of partial differential equations is solved in this section using the spectral relaxation method (SRM). SRM is an iterative procedure that employs the Gauss-Siedel type of relaxation approach to linearize and decouple the system of coupled differential equations [42,43]. The resulting non-linear differential equations are further discretized and solved with the Chebyshev pseudo-spectral method over the well-defined colocation points.…”
