“…The heat and mass transfer in biological tissue is one of the most basic characteristics of living system [1][2][3]. The metabolism of cells is always accompanied with the generation of heat, which means the thermal information of living body is closely related with the metabolism [4][5][6].…”

Abstract:Heat is the product following the metabolism of cells, and the metabolism is closely related with the pathological information of living organism. So, there are strong ties between the heat distribution and the pathological state in living organism. In this paper, the mathematical function δ is introduced in the classical Pennes bio-heat transfer equation as the point heat source. By simplifying the boundary conditions, a novel bio-heat transfer model is established and solved in a spherical coordinate system. Based on the temperature distribution of human body surface, the information of heat source is mined layer by layer, and the corresponding q-r curve of heat intensity varying with depth is acquired combining the fitting method of Lorentz curve. According to a large number of clinical confirmed cases and statistics, the diagnostic criteria judging diseases by q-r curve are proposed. Five typical clinical practices are performed and four of the diagnosis results are very consistent with those of molybdenum target (MT) X-ray, B-ultrasonic images and pathological examination, one gives the result of early stage malignant tumor that MT X-ray and B-ultrasonic can't check out. It is a radiation-free green method with noninvasive diagnostic procedure and accurate diagnosis result.

“…The steady-temperature is so important that it can be used, for instance, to diagnose in a non-invasive manner tumors by the measure of the temperature at the skin surface, especially those near to skin [13,21]. Nevertheless, the skin-surface temperature may also be employed in inverse analyses to estimate either the location and size of tumors or some of the tissue properties such as the blood perfusion rate [22,23,24,25].…”

Lobosco, 3D numerical simulations on GPUs of hyperthermia with nanoparticles by a nonlinear bioheat model, Journal of Computational and Applied Mathematics (2015), http://dx. AbstractThis paper deals with the numerical modeling of hyperthermia treatments by magnetic nanoparticles considering a 3D nonlinear Pennes' bioheat transfer model with a temperature-dependent blood perfusion in order to yield more accurate results. The tissue is modeled considering skin, fat and muscle layers in addition to the tumor. The FDM in a heterogeneous medium is employed and the resulting system of nonlinear equations in the time domain is solved by a predictor-multicorrector algorithm. Since the execution of the three-dimensional model requires a large amount of time, CUDA is used to speedup it. Experimental results showed that the parallelization with CUDA was very effective in improving performance, yielding gains up to 242 times when compared to the sequential execution time.

“…In recent decades, the study of heat transfer in biological tissues has taken a relevant importance due to the medical interest for applying this fundamental knowledge to the thermal detection of cancerous tumors [1][2][3][4], and for the destruction of dangerous tissues [5,6]. In the last years, the number of patients associated with different illness caused for cancerous tumors has increased exponentially, implying serious problems in the health care and in the economy of the world [1].…”

“…In the last years, the number of patients associated with different illness caused for cancerous tumors has increased exponentially, implying serious problems in the health care and in the economy of the world [1]. Therefore, many researchers have proposed different alternatives to develop new techniques or methodologies, cheaper and less invasive to detect or destroy dangerous tissues.…”
