A total of 85 consecutive patients had their wound area measured. The procedure was executed in two parts. The first was to take photographs of the wound using a smartphone and measure the area using the imitoMeasure application (imito; imito AG, Zurich, Switzerland) by two raters. The second was to take photographs of the same wound using a 10-megapixel digital camera and posterior measurement of the area using ImageJ software (National Institutes of Health, Bethesda, Md) by one operator. The mean area of the wounds was 12.20 ± 10.45 cm for imito and 12.67 ± 10.86 cm for ImageJ measurement. The interclass correlation coefficient (ICC) between ImageJ and imito was 0.978 for a single measure and 0.989 for the average measure. Considering the two measurements, the ICC demonstrated excellent interobserver correlation using imito (0.987). Larger wounds had a greater difference between the methods (4.28% greater with the ImageJ measurement when considering areas >9 cm). No difference was found between iOS (ICC, 0.995) and android (ICC, 0.970) smartphone operating systems. The smartphone application is a useful method for area measurement with excellent accuracy compared with digital photography and the ImageJ processing tool.
共有85例连续患者的伤口面积被测量。该程序分两部分执行。第一部分是使用智能手机拍摄伤口照片，并由两名评估者使用imitoMeasure应用程序（imito；imito AG，瑞士苏黎世）测量面积。第二部分是使用1000万像素数码相机拍摄同一伤口照片，并由一名操作人员使用ImageJ软件（美国国立卫生研究院，马里兰州贝塞斯达）进行后期面积测量。imito测量的伤口平均面积为12.20±10.45平方厘米，ImageJ测量的为12.67±10.86平方厘米。ImageJ和imito之间的组内相关系数（ICC），单次测量为0.978，平均测量为0.989。综合两种测量方法，使用imito时ICC显示观察者间具有极好的相关性（0.987）。较大的伤口在两种方法之间的差异更大（当考虑面积>9平方厘米时，ImageJ测量的结果大4.28%）。在iOS（ICC，0.995）和安卓（ICC，0.970）智能手机操作系统之间未发现差异。与数码摄影和ImageJ处理工具相比，智能手机应用程序是一种具有极高准确性的面积测量有用方法。
