在一项多年的临床研究中，作者测试了光学技术诊断烧伤创面组织损伤的可靠性。使用一种方便的床边非侵入性仪器（烧伤深度指示器）测量光学反射率，该仪器由一位作者设计和制造。结果表明，这种光学技术比传统方法更准确地预测烧伤创面的愈合时间，否则很难评估烧伤创面的愈合时间。使用三层 Kubelka-Munk 模型对烧伤创面的光学特性进行建模。我们发现焦痂厚度以及真皮中血液的体积分数和氧饱和度决定了烧伤的光学特性。反过来，这些因素又与烧伤深度和愈合潜力相关。
In a multiyear clinical study, the authors tested the reliability of an optical technique for diagnosing tissue damage on burn wounds. Optical reflectivity was measured using a convenient, bedside, noninvasive instrument (the Burn Depth Indicator), which was designed and built by one of the authors. The results show that this optical technique is more accurate than conventional methods for predicting the healing time of burn wounds which are otherwise difficult to assess. The optical properties of burn wounds were modeled using a three layer Kubelka-Munk model. We found that eschar thickness and the volume fraction and oxygen saturation of blood in the dermis determine the optical properties of the burn. These factors, in turn, are known to correlate with the burn depth and healing potential.
