烧伤面积的精确估算对现场急救、休克复苏、手术方式选择、营养支持、护理及预后起到至关重要的作用。目前临床上广泛采用的烧伤面积估算方法主要有"Lund- Browder 表格法"、"九分法"、"手掌面积法"等，它们均为二维估算，没有考虑年龄、性别、种族、体质、身体畸形（如肢体残缺）、生理状态等相关因素，存在较大差异，同时不同评估者诊断的主观差异性较大，因此严重影响了诊断与治疗工作，对救治、护理及预后产生较大影响。本课题组在充分的研究现有的计算机辅助烧伤面积诊断的基础上，设计并研发一套个体化、经济实用、便携式的人体3D扫描系统，建立患者个体化的3D模型，能够精确、快速计算人体体表面积，用于烧伤面积及百分比的估算。该技术还可应用于创伤、各种体表疾患（疤痕、皮肤疾病等）皮损的范围测算，另外通过全身和各部位体积的计算用于肥胖疾病的诊治和疗效的观察。

Accurate estimation of the burn area is crucial to on-site first aid, resuscitation, surgical options, nutritional support, care and prognosis. The widely used burn area estimation methods in clinical practice are " Lund & Browder chart", "Rule of Nines" and "Rule of Palms", which are two-dimensional estimate methods, lacking age, sex, race, body mass, physical deformities, physiological status and other relevant influencing factors, causing significant differences. Meanwhile, different assessors have subjective differences. These defects seriously impact on the diagnosis, treatment and prognosis. Our research group design and develop an individualized, economical and portable body 3D scanning system, which could establish patient's individual 3D model, accurately and quickly calculate the human body surface area for burn area and percentage estimates. This technology can also be applied to calculate various surface lesions (trauma, scars, skin diseases, etc.), diagnosis and treatment of obesity.
