摘要
颜面部软组织三维图像信息的获取方法有莫尔云纹、激光扫描和三维立体摄影测量。莫尔条纹法具有成本低、非介入性等优点,但其面部重建还是不够直观且灵敏度较低。激光扫描精度高,立体重构快捷逼真;但其易伤害眼睛,只捕捉表面形貌,无法观察软组织质地;数据采集时间较长,易增加运动伪影。三维立体摄影测量为非介入性的,安全无创;拍摄迅速,图像采集时间短,无运动伪影的风险;数据存储方便,查询快捷,可对归档的图像进行后续的反复分析;提高了测量速度和精度;与被检查对象无接触;医师与患者间的沟通更加便捷,有利于医师设计和调整更符合患者要求的个体化治疗方案。三维立体摄影测量也令今后正畸和正颌专家的远程网上诊疗成为可能,有可能成为口腔颜面部修复重建的常规检查项目。
3D surface imaging technologies include Moire topography, laser scanning, and three-dimensional stereophotogrammetry. Although Molte topography presents the advantages of low-cost and non-invasiveness, its facial reconstruction is still not intuitive and lacks sensitivity. Laser scanning is high-precision, realistic, and efficient in three- dimensional reconstruction but can easily damage the eyes. Only capture surface morphology renders the observation of soft tissue texture difficult. Moreover, longer capture time is likely to increase motion artifacts. Three-dimensional stereophotogrammetry offers significant advantages, such as safety, non-invasive, rapid capture speeds without the risk of motion artifacts, data storage convenience, and ease of inquiry, which enables subsequent and repeated analysis of archived images without contact with the inspected objects. This approach is more convenient for communication between doctors and patients and benefits the design and adjustment of the patient＇s individual treatment plan. Three-dimensional stereophotogrammetry also renders future remote online clinical diagnosis and treatment possible and may also become a routine examination for oral and maxillofacial reconstruction.
