    • 本文目的為研究動態紅外線熱成像(active dynamic thermography, ADT)應用於燒燙傷傷口診斷。首先利用鹵素燈照射皮膚一段時間，使皮膚表面溫度上升約2.5°C，再利用紅外線量測皮膚表面自然冷卻過程之溫度變化，接著對皮膚表面溫度變化進行分析，即可判斷出燒傷傷口燒傷程度。
    首先必須建立三維皮膚熱傳模型，其中包含表皮層、真皮層與動靜脈血管。分析結果發現終端血管(terminal vessels)之血液流率對於組織平均溫度影響不大；相較之下，Biot number(Bi)對組織平均溫度影響很大，並且發現組織平均溫度線在真皮層與表皮層中皆近乎於直線，接著將三維之計算結果轉換為一維，以利於減少計算量，再拓展到軸對稱圓柱座標，建立燒傷皮膚並開始進行ADT診斷過程之數值模擬。
    本文發現了ADT診斷中，判斷皮膚組織燒傷範圍之參數，以此參數判斷燒傷範圍之準確性極高。燒傷傷口越大，準確性越高，但由於誤差也會隨時間增加，因此建議診斷時間為前30秒內。
