| 摘 要： | 基于两点法测量原理,提出了一种通过三点测温无损确定柱状生物活体组织热参数的新方法,建立了该方法的理论模型,数值计算分析了导热系数、血液灌注率体积热容量等参数对温度变化的影响,以及这些热参数的灵敏度系数.研究结果表明,活体组织的上述热参数的灵敏度系数是线性无关的,可以通过所提出的三点法同时进行测量.

| Abstract: | Based on the principle of two-point measurement method, a measuring technique for thermal para-
meters of living tissue by using three-point temperature measurements was proposed. The corresponding theoretical
model was established. The effects of thermal conductivity blood perfusion and volumetric heat capacity on the tem-
perature variation were analyzed through numerical calculations. The results of sensitivity analysis show that the
sensitivity coefficients of these thermal parameters are linearly independent each other, and thereby can be measured
simultaneously by using this three-point method. |
