本文首次描述了一种计算机程序系统，该系统能够使用计算机层析成像数据，以精确和一致的方式自动定位、测量和描述[人体]解剖结构。系统的输入包括任何数字化的射线照相数据。计算机辅助断层扫描（CAT）的头部扫描被用于第一次实施。使用这些数据和代表平均正常图像的理想化视图的预定义地图集图像，创建了个性化地图集。从个体化图谱中，可以计算出结构尺寸、密度、位置位移和变形。使用高分辨率数据（如CAT扫描）创建的个性化地图集可以直接叠加在使用低分辨率模式（如正电子发射断层扫描图像）获得的图像上。这允许结构的精确定位较差的二次成像方式可视化。该系统能够使用二维或三维数据。
A system of computer programs is described which, for the 1st time, is able to use computerized tomographic data to automatically locate, measure and describe [human] anatomatical structures of interest with accuracy and consistency. Input to the system consists of any digitized radiographic data. Computer assisted tomographic (CAT) scans of the head were used in this first implementation. Using these data and a predefined atlas picture representing an idealized view of the average normal image, an individualized atlas was created. From the individualized atlas, structure size, density, location displacement and distortion may be calculated. The individualized atlas created using high resolution data, such as the CAT scan, may then be directly superimposed on pictures obtained using lower resolution modalities, such as positron emisison tomographic scan images. This allows the precise location of structures poorly visualized by the secondary imaging modality. This system is capable of using either 2- or 3-dimensional data.
