毕业设计（论文）-肿瘤热疗原理的COMSOL仿真精选.docVIP

肿瘤热疗原理的COMSOL仿真 摘 要 肿瘤热疗是泛指用加热来治疗肿瘤的治疗方法。基本原理是利用物理能量加热人体全身或局部，使肿瘤组织温度上升到有效治疗温度，并维持一定时间，利用正常组织和肿瘤细胞对温度耐受能力的差异，达到既能使肿瘤细胞凋亡、又不损伤正常组织的治疗目的COMSOL Multi physics是全球多物理场建模与仿真解决方案的提倡者和领导者它无与伦比的能力，使所有的物理现象可以在计算机上完美重现。利用它改进医疗设备的性能并提供更准确的诊COMSOL Multi physics以高效的计算性能和耦合分析能力实现了高度精确的数值仿真COMSOL Multi physics，电磁，生物传热 ABSTRACT Tumor heat treatment is referring to use heat to treat cancer treatments. The basic principle is to use physical energy heating human body or local, make tumor tissue temperature rise to effective treatment temperature, and maintain certain time, using the normal tissue and tumor cells the difference of temperature tolerance ability, achieve both can make tumor cell apoptosis, and no damage to the normal tissue of therapeutic purposes. COMSOL Multi physics is global multi-physical modeling and simulation solutions leader, it advocates and unparalleled ability, it can make all of the physical phenomena can be perfect on computer again. In this design, use it to improve medical equipment performance and provide more accurate diagnosis and treatment. COMSOL Multi physics with the efficient computational performance and the coupling analysis ability realize the highly accurate numerical simulation. Through the COMSOL for tumor thermotherapy provide accurate numerical simulation, this diagnosis and treatment, the numerical as basis, the realization to the tumor high-precision, correct treatment.
