The aim of this study was to investigate the validity and reliability of a novel three-dimensional imaging technique using Artec MHT 3D Scanner for measuring the wound surface area.
The validity was tested by measuring the surface area of 60 stickers (gold standard) on 20 volunteers. Stickers with standardized areas of 2590, 7875, and 15,540 mm were applied on the thorax, forearm, and thigh, respectively. For the reliability test, 58 burn wounds on 48 patients were assessed twice by two different observers with the Artec MHT 3D Scanner. Scanning, post-processing, and surface area measurements were performed by two clinicians.
The results for the validity analysis showed an intraclass correlation coefficient of 0.99 and coefficient of variation of the thorax, forearm, and thigh were 1.1%, 0.9%, and 0.6%, respectively. The reliability analysis showed an intraclass correlation coefficient of 0.99, a coefficient of variation of 6.3%, and limits of agreement between measurements of two observers were calculated at 0 ± 0.17 × mean surface area.
Three-dimensional imaging using the Artec MHT 3D Scanner is a valid and reliable method for measuring the wound surface area.
本研究旨在探讨使用Artec MHT 3D扫描仪测量伤口表面积的一种新型三维成像技术的有效性和可靠性。
通过测量20名志愿者身上60张贴纸（金标准）的表面积来测试有效性。将标准化面积分别为2590、7875和15540平方毫米的贴纸分别贴在胸部、前臂和大腿上。为进行可靠性测试，两名不同的观察者使用Artec MHT 3D扫描仪对48例患者身上的58处烧伤创面进行了两次评估。扫描、后处理和表面积测量由两名临床医生进行。
有效性分析结果显示组内相关系数为0.99，胸部、前臂和大腿的变异系数分别为1.1%、0.9%和0.6%。可靠性分析显示组内相关系数为0.99，变异系数为6.3%，两名观察者测量结果之间的一致性界限计算为0±0.17×平均表面积。
使用Artec MHT 3D扫描仪进行三维成像测量伤口表面积是一种有效且可靠的方法。
