Laser诱导的热扩散限制组织凝固:问题和一般性质
Laser Induced Heat Diffusion Limited Tissue Coagulation: Problem and General Properties
摘要:
以前,我们已经开发了一个自由边界模型,激光吸收引起的局部热凝固时,直接受激光影响的组织区域是足够小,热扩散到周围组织支配的坏死生长。在本论文中,调查所获得的结果,我们国家的观点在这些条件下的坏死形成的基础上的个人激光治疗模式表现出特定的属性。具体而言,粗略地说,所产生的坏死域的大小由组织的物理特性及其对局部加热的响应以及由施用器形式而不是治疗持续时间和照射功率确定。
英文摘要:
Previously we have developed a free boundary model for local thermal coagulation induced by laser light absorption when the tissue region affected directly by laser light is sufficiently small and heat diffusion into the surrounding tissue governs the necrosis growth. In the present paper surveying the obtained results we state the point of view on the necrosis formation under these conditions as the basis of an individual laser therapy mode exhibiting specific properties. In particular, roughly speaking, the size of the resulting necrosis domain is determined by the physical characteristics of the tissue and its response to local heating, and by the applicator form rather than the treatment duration and the irradiation power.
