A mathematical model is presented for the calculation of the 3-D time-dependent temperature distribution in a biological tissue (slab) irradiated by a laser beam of rectangular or Gaussian profile, which takes into account the different thermooptical properties of the tissue. Detailed consideration is given to the phenomenon of redistributive internal scattering, which is of noticeable magnitude in the irradiation by the argon-ion and Nd:YAG lasers commonly used for tissue coagulation in medicine. Satisfactory agreement is found with temperature measurements performed with a thermocamera, and the CO(2) and Nd:YAG lasers are compared qualitatively and quantitatively.
提出了一个数学模型，用于计算受矩形或高斯分布激光束照射的生物组织（平板）中随时间变化的三维温度分布，该模型考虑了组织不同的热光学性质。详细考虑了再分布内部散射现象，这种现象在医学上常用于组织凝固的氩离子激光和Nd:YAG激光照射中具有显著量级。与用热像仪进行的温度测量结果取得了满意的一致性，并对CO(2)激光和Nd:YAG激光进行了定性和定量比较。
