Numerical analysis for determination of the presence of a tumor and estimation of its size and location in a tissue

Q-r curve of thermal tomography and its clinical application on breast tumor diagnosis

“…So, there are strong ties between the thermal information and the pathological changes. If there exist diseases or functional changes in a certain part of the human body, the speed of blood flow and cell metabolism will change correspondingly, which will lead to the thermal variation in this area [9][10][11]. However, at the early stage of lesion, the human body can't perceive the temperature changes of cells, only if the temperature of abnormal cells reaches to a quantitative change, the uncomfortable symptoms will be perceived [10][11][12][13].…”

“…In order to mine the valuable 3-dimensional heat distribution data based on temperature distribution of body surface, many research groups have carried out in-depth studies and made a series of achievements [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26]. This present paper aims to acquire the q-r characteristic curve of the heat intensity varying with depth of tomography based on the temperature distribution characteristics of tumor in different stages.…”

Theoretical analysis of coupled thermal and denaturation processes in living tissues subject to a uniform surface heating condition

“…(2) and (3), x; y and z are the spacial coordinates and t is the time. The thermal conductivity, the blood perfusion rate and the metabolic heat generated are temperature-dependent properties and are defined as k T…”

“…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].…”

Numerical simulation of dual-phase-lag bioheat transfer model during thermal therapy

“…Therefore, hyperthermia improves the result of the conventional treatment within the framework of multi-modal treatment concepts. For the success of hyperthermia treatment, precise prediction and control of temperature are always needed [2][3][4][5][6] . Heat transfer analysis in living biological tissues is complex due to their non-homogeneous inner structure.…”
