摘要/Abstract

摘要：

目的探讨建立双侧内耳统计形状模型的方法和影响因素，并探讨使用平均双侧内耳模型作为带空间信息的标准模型。方法通过Otsu法以及手动分割37例双侧内耳模型，对模型进行配准并生成统计形状模型，观察测量标准模型空间信息。结果 Otsu 法可以分割获取高质量内耳模型，模型配准后使用Statismo 0.81软件可以生成稳定的内耳统计形状模型，其导出的平均模型空间方向信息具有代表性。结论双侧内耳统计形状模型可以导出平均模型作为带空间方向信息的标准模型。

Abstract:

Objective To explore the method and influencing factors of establishing a statistical shape model of the bilateral inner ears, and to investigate the use of the mean model as a standard bilateral inner ear model with spatial information. Methods A total of 37 bilateral inner ear models were segmented through Otsu method and manual segmentation. Those models were registered to generate a statistical shape model. The mean model as a standard model was observed for the spatial information. Results High quality inner ear model was obtained through Otsu method segmentation. After those models were registered, the Statismo software was used to generate inner ear statistical shape model stably. The spatial direction information of the model was representative. Conclusion The statistical shape model of the bilateral inner ear can derive the mean model as the standard model with spatial orientation information.
