In this paper a computer-based system for burnt surface area estimation (BAI), is presented. First, a 3D model of a patient, adapted to age, weight, gender and constitution is created. On this 3D model, physicians represent both burns as well as burn depth allowing the burnt surface area to be automatically calculated by the system. Each patient models as well as photographs and burn area estimation can be stored. Therefore, these data can be included in the patient's clinical records for further review. Validation of this system was performed. In a first experiment, artificial known sized paper patches were attached to different parts of the body in 37 volunteers. A panel of 5 experts diagnosed the extent of the patches using the Rule of Nines. Besides, our system estimated the area of the "artificial burn". In order to validate the null hypothesis, Student's t-test was applied to collected data. In addition, intraclass correlation coefficient (ICC) was calculated and a value of 0.9918 was obtained, demonstrating that the reliability of the program in calculating the area is of 99%. In a second experiment, the burnt skin areas of 80 patients were calculated using BAI system and the Rule of Nines. A comparison between these two measuring methods was performed via t-Student test and ICC. The hypothesis of null difference between both measures is only true for deep dermal burns and the ICC is significantly different, indicating that the area estimation calculated by applying classical techniques can result in a wrong diagnose of the burnt surface.
本文提出了一种基于计算机的烧伤面积估计（BAI）系统。首先，创建一个适应年龄、体重、性别和体质的患者 3D 模型。在这个 3D 模型上，医生可以表示烧伤以及烧伤深度，从而使系统能够自动计算烧伤面积。每个患者的模型以及照片和烧伤面积估计都可以存储。因此，这些数据可以包含在患者的临床记录中以备进一步审查。该系统已经过验证。在第一个实验中，将已知大小的纸质补丁人工贴在 37 名志愿者身体的不同部位。一个由 5 名专家组成的小组使用九分法诊断补丁的范围。此外，我们的系统估计了“人工烧伤”的面积。为了验证零假设，对收集的数据应用了学生 t 检验。此外，计算了组内相关系数（ICC），得到了 0.9918 的值，表明该程序计算面积的可靠性为 99%。在第二个实验中，使用 BAI 系统和九分法计算了 80 名患者的烧伤皮肤面积。通过 t-Student 检验和 ICC 对这两种测量方法进行了比较。只有当烧伤为深达真皮时，两种测量方法之间的零假设差异假设才成立，ICC 显著不同，这表明应用经典技术计算的面积估计可能导致烧伤表面的错误诊断。
