背景资料：本研究的目的是定义一个采集协议，是明确的，精确的，可重复的，简单的，快速的，这是有用的面部软组织的人体测量特征的分析。方法：进行分析，根据一个新的临床仪器协议，包括四个不同的阶段：（1）在将进行场分析的空间中设置便携式设备，（2）对象的准备和空间定位，（3）扫描具有不同面部表情的对象，以及（4）数据的处理和加工。该协议进行了测试的样本，包括66名女性受试者（64名白人，1名埃塞俄比亚人和1名巴西人）谁是决赛的意大利国家选美比赛在2010年。为了说明该方法的潜力，我们在这里报告的测量和全面的分析，进行了面部模型的一个科目谁是scanned.Results：这种新的协议，用于获取的面孔被证明是快速的（阶段1，约1小时;阶段2，约1.5分钟;阶段3，约1.5分钟;阶段4，约15分钟），简单（第1至3阶段需要较短的操作员培训期;仅阶段4需要专家操作员），可重复（通过直接触诊解剖标志并标记其在面部上的位置，解决了在数字模型上识别这些相同标志的问题），可靠且精确（测量的平均精度，在面部的整个表面上为0.5至0.6mm）。结论：这种标准化允许在相同的条件下以可靠和快速的过程对所有被扫描的受试者进行受试者的映射。
Background: The objective of this study is to define an acquisition protocol that is clear, precise, repeatable, simple, fast and that is useful for analysis of the anthropometric characteristics of the soft tissue of the face.Methods: The analysis was carried out according to a new clinical instrumental protocol that comprises four distinct phases: (1) setup of portable equipment in the space in which field analysis will be performed, (2) preparation of the subject and spatial positioning, (3) scanning of the subject with different facial expressions, and (4) treatment and processing of data. The protocol was tested on a sample comprising 66 female subjects (64 Caucasian, 1 Ethiopian, and 1 Brazilian) who were the finalists of an Italian national beauty contest in 2010. To illustrate the potential of the method, we report here the measurements and full analysis that were carried out on the facial model of one of the subjects who was scanned.Results: This new protocol for the acquisition of faces is shown to be fast (phase 1, about 1 h; phase 2, about 1.5 min; phase 3, about 1.5 min; phase 4, about 15 min), simple (phases 1 to 3 requiring a short operator training period; only phase 4 requires expert operators), repeatable (with direct palpation of anatomical landmarks and marking of their positions on the face, the problem of identification of these same landmarks on the digital model is solved), reliable and precise (average precision of measurements, 0.5 to 0.6 mm over the entire surface of the face).Conclusions: This standardization allows the mapping of the subjects to be carried out following the same conditions in a reliable and fast process for all of the subjects scanned.
