用于法医学同一认定的额窦CT编码

Forensic Identification by Coding of Frontal Sinus Characteristics of CT

目的使用头颅CT图像重建冠状位鼻骨切面研究额窦观测指标,以编制特异的识别编码。方法通过距离数值量和形态学描述对额窦CT图像进行分析。额窦同一认定识别编码为:右侧额窦部分隔数,形态-额窦中间隔位置,形态-左侧额窦部分隔数,形态;右侧额窦上缘弓形弯曲数(右侧最高峰位置,最低峰位置)-左侧额窦上缘弓形弯曲数(左侧最高峰位置,最低峰位置);右侧额窦宽度,高度-额窦总宽度-左侧额窦宽度,高度。结果额窦识别编码具有高度个人特异性,但性别差异无统计学意义(P>0.05)。结论额窦CT片的识别编码可用于法医学同一认定,但不能作为性别判断的指标。

Objective To explore observing parameters of frontal sinus using reconstructive coronal nose bone sections of the head CT images and to establish the special identification codes.Methods CT images of the frontal sinus were analyzed by using distance measurement and morphological description.The discrimination codes of frontal sinus identification were： the number of right partial septa,shape-the location of the central septa,shape-the number of left partial septa,shape;the number of arches of right upper scalloping（the location of the right highest scalloping,the location of the right lowest scalloping）-the number of arches of left upper scalloping（the location of the left highest scalloping,the location of the left lowest scalloping）;the width,height of the right sinus-the total width of sinus-the width,height of the left sinus.Results The identification codes of the frontal sinus were highly variable individually,but the codes were not statistically differences between males and females（P0.05）.Conclusion The identification codes of frontal sinus could be used for forensic individual identification,but not for sex determination.
