【摘要】 无创获取生物体变物性参数的方法，是生物传热研究的难题之一。本文提出了利用人舌红外热图优化计算舌血液灌注率的方法。通过热象仪测取人舌的二维温度场，根据给定的某些物性参数用生物传热模型进行逆运算，从而确定出人舌的血液灌注率。更多还原

【Abstract】 The intact method of the inconstant physiological parameter measurements for living things is one of the difficult problems in the study of bio-heat transfer. In this paper, a new optimization method for calculating the blood perfusion ratio of the tongue which utilizes the infrared thermal-image is presented. Two-dimension temperature distribution is deternmined via the thermovision. Combining the temperature distribution and some given parameters, we perform the inverse calculation with bio-heat transfer model to estimate the blood flow.更多还原
