A graphical solution of the temperature increase at the surface of a homogeneous solid due to a linear heat source perpendicular to the surface is given. The calculations correspond to clinical situations for studies of the skin temperature increase over vessels approaching the surface from deeper layers of tissue. Estimations have been made of the maximum distance from the skin surface at which a vein of given diameter may be positioned to be detected in a thermogram. The necessary heat source power to produce a detectable increase in skin temperature is presented graphically as a function of heat source depth. The results can be used for the analysis of the skin temperature pattern by infrared thermography.
给出了由于垂直于表面的线性热源导致均匀固体表面温度升高的图形解。这些计算对应于研究从组织深层接近表面的血管上皮肤温度升高的临床情况。已经对给定直径的静脉在热像图中可被检测到的距皮肤表面的最大距离进行了估计。产生可检测到的皮肤温度升高所需的热源功率作为热源深度的函数以图形方式给出。结果可用于通过红外热成像分析皮肤温度模式。
