摘要

电磁场与生物之间的相互作用日益增强。关于这种相互作用的文献中有成千上万的研究。到目前为止,大多数关于生物传热的研究都集中在电磁场造成的损伤上。然而,电磁场的治疗作用却被忽视了。本研究旨在带来一个新的视角。利用生物传热方程,研究了不同参数对电磁场的温度效应。在本研究中,Pennes' s生物传热方程的解析解与实际肌肉组织参数一起进行了评估。通过尝试不同的参数变化,观察灌注常数、导热系数等参数对组织升温的影响。根据这项研究,磁加热过程应用于物理治疗的设备设计将成为可能。在输入组织参数和电磁场值后,就可以发现根据本研究得到的公式可以观察到什么样的温度变化。用图形分析了热导系数、血液灌注值和换热系数对温度分布的影响。在研究中对随机选择的热参数的影响进行了评估。本研究显示了电磁场对组织热参数的影响程度。

Elektromanyetik Alana Maruz Kalmış Kas Dokusunun Termal Analizi
The interaction between electromagnetic fields and biological masses is increasing day by day. There are thousands of studies in the literature on this interaction. Until now, most of the studies on bio heat transfer have focused on damage caused by electromagnetic fields. However, the therapeutic side of electromagnetic fields has been neglected. This study aimed to bring a new perspective. Using the bio heat transfer equation, the temperature effect of different parameters due to the electromagnetic field was investigated. In the present study, the analytical solution of Pennes' bioheat transfer equation was evaluated together with real muscle tissue parameters. By trying different parameter variations, the effect of parameters such as perfusion constant and thermal conductivity coefficient on tissue warming was observed. In the light of this study, device designs for magnetic heating processes applied in physiotherapy will be possible. After entering the tissue parameters and electromagnetic field values, it was possible to find out what kind of temperature change can be observed as a result of the formulation obtained in this study. The effects of thermal conductivity coefficient, blood perfusion value and heat transfer coefficient on temperature distribution were graphically analyzed. Effect of randomly selected thermal parameters are evaluated within the study. This study has shown to what extent the increasing thermal parameters of the tissue will be affected by the electromagnetic field.
