在激光治疗中，患者皮肤色素沉着程度的差异是可能导致医疗事故的一个重要因素。然而，传统的热传递模型无法分析色素沉着程度对激光治疗的影响。为此，我们提出了一种考虑点热源的激光显微辐射传热模型。在提出的模型中，皮肤被视为由两层组成的散装介质，即正常层和色素沉着层，色素沉着层含有更多的黑素体，其特定体积分数（fv,mel）为色素沉着程度。利用提出的模型，发现皮肤组织吸收激光能量的分布和温升受色素沉着程度的影响。当fv，melis高时，单个黑素体的吸收能量，因此色素沉着层的温升低于更深的皮肤组织。研究还表明，随着年龄的增加，黑素体之间的距离会减小。当温度升高时，黑素体之间的皮肤组织温度升高。
In laser treatments, the difference in patient's degree of skin pigmentation is an important factor that can lead to medical accidents. However, the conventional heat transfer model is not available to analyze the effect of degree of pigmentation on the laser treatments. Therefore, we propose a new microscopic radiation heat transfer model that takes into account the point heat sources for the laser treatments. In the proposed model, skin considered as a bulk medium consisting of two layers, namely normal and pigmentation layers with the latter containing a larger number of melanosomes having a specific volume fraction (fv,mel) as the degree of pigmentation. Using the proposed model, it was found that the distribution of the absorbed laser energy and temperature rise of the skin tissue is affected by the degree of pigmentation. Whenfv,melis high, the absorbed energy per single melanosome and thus the temperature rise of the pigmentation layer is lower than that in the deeper skin tissue. It was also shown that depending onfv,mel, the distance between melanosomes decreases. Whenfv,melis high, the temperature of skin tissue between melanosomes increases.
