PURPOSE
To develop an anatomic atlas of the human head based on a volume model derived from MR and CT.
METHODS
Every voxel of this model was labeled by a neuroanatomist concerning its membership to a structural and/or functional region. A computer program was written that, instead of displaying precomputed images, allows the user to choose and compose arbitrary views.
RESULTS
The user can subtract parts and ask for annotations just by using the mouse. Conversely, one can compose images by choosing objects from the list of anatomical constituents which is displayed on the screen. A set of dissection tools allows a "look and feel" that comes near to a true dissection. Operations that are not possible in a real dissection, such as reassembly or filling cavities, can be performed.
CONCLUSION
The authors have developed a computerized model that can be used for anatomy teaching and also as a reference for radiologists or surgeons. To replace classical atlases, the spatial resolution must be improved and speed must approach real time. Functional imaging data (position emission tomography and single photon emission CT) can be added to the system. The system is mobile and can be situated in classrooms, operating rooms, reading rooms, and libraries.
目的
基于从磁共振成像（MR）和计算机断层扫描（CT）获取的体模型开发人体头部解剖图谱。
方法
该模型的每个体素由神经解剖学家根据其所属的结构和/或功能区域进行标记。编写了一个计算机程序，该程序并非显示预先计算好的图像，而是允许用户选择并组合任意视图。
结果
用户仅通过使用鼠标就能减去部分并要求添加注释。相反，用户可以从屏幕上显示的解剖成分列表中选择对象来组合图像。一组解剖工具营造出一种接近真实解剖的“观感”。可以执行在真实解剖中无法进行的操作，例如重新组装或填充腔体。
结论
作者开发了一种计算机化模型，可用于解剖学教学，也可作为放射科医生或外科医生的参考。为了取代传统图谱，必须提高空间分辨率且速度必须接近实时。功能成像数据（正电子发射断层扫描和单光子发射计算机断层扫描）可添加到该系统中。该系统便于移动，可放置在教室、手术室、阅览室和图书馆。
