摘　　要：目的使用坐标转换的数学方法处理颅脑影像数据,寻找成人颅内松果体、侧脑室额角体表颞侧投影点与同侧外耳门的空间关系。方法在CT后处理工作站记录30例影像正常人的外耳门、外眦、松果体、侧脑室额角的原始数据。经数学方法转化为平行大脑镰的头皮听眦线(OM线)为基础,外耳门为原点,听眦线和对侧外耳门为平面的新三维坐标系下的坐标数据,得出松果体和侧脑室额角体的新坐标数据,并将数据进行统计处理。结果松果体在X、Y、Z轴上数值及侧脑室额角在X轴上数值男女差异有统计学意义(P<0.01);Y、Z轴上侧脑室额角,男女差异无统计学意义(P>0.05)。结论松果体和侧脑室额角距外耳门前后、内外及上下均有相对固定的区间值,二者在男女中OM线的前后位置有明显差异,该数据可为临床手术相关定位提供参考。Objective To investigate the spatial relationship between adult acusticus externus and the pineal gland,cornu frontale ventriculi lateralis by using the mathematical methods of coordinate transformation.Methods The original 3-dimensional coordinate data of 30 patients were obtained on thinner CT scan from CT workstation,including meatus acusticus externus,angulus oculi lateralis,the pineal gland,cornu frontale ventriculi lateralis.Then,the original cordinate values were transformed to those in the new cordinate system （line between angulus oculi lateralis and meatus acusticus externus,meatus acusticus externus as origin,OM line and contralaterally meatus acusticus externus as flat）and statistics data were processed. Results The values of the pineal gland on X,Y,Z axis and cornu frontale ventriculi lateralis on X axis had significant difference between male and female（P〈0.01）.The values of cornu frontale ventriculi lateralis on Y,Z axis had no significant difference between male and female（P〉0.05）. Conclusion In this new cordinate system,the pineal gland and cornu frontale ventriculi lateralis in male and female adults had relatively stable spatial values,and had significant difference on OM＆amp;nbsp;line,which can be reference for operations.
