Interest in the placing of landmarks and subsequent morphometric analyses of shape for 3D data has increased with the increasing accessibility of computed tomography (CT) scanners. However, current computer programs for this task suffer from various practical drawbacks. We present here a free software tool that overcomes many of these problems.
The TINA Manual Landmarking Tool was developed for the digitization of 3D data sets. It enables the generation of a modifiable 3D volume rendering display plus matching orthogonal 2D cross-sections from DICOM files. The object can be rotated and axes defined and fixed. Predefined lists of landmarks can be loaded and the landmarks identified within any of the representations. Output files are stored in various established formats, depending on the preferred evaluation software.
The software tool presented here provides several options facilitating the placing of landmarks on 3D objects, including volume rendering from DICOM files, definition and fixation of meaningful axes, easy import, placement, control, and export of landmarks, and handling of large datasets. The TINA Manual Landmark Tool runs under Linux and can be obtained for free from http://www.tina-vision.net/tarballs/.
随着计算机断层扫描（CT）扫描仪的普及，人们对 3D 数据的地标定位和后续形态计量分析的兴趣日益增加。然而，目前用于此任务的计算机程序存在各种实际问题。我们在此介绍一款免费软件工具，它克服了许多这些问题。
TINA 手动地标定位工具是为 3D 数据集的数字化而开发的。它可以生成可修改的 3D 体积渲染显示，以及来自 DICOM 文件的匹配正交 2D 横截面。可以旋转对象并定义和固定轴。可以加载预定义的地标列表，并在任何表示形式中识别地标。输出文件以各种已建立的格式存储，具体取决于首选的评估软件。
本文介绍的软件工具提供了几种方便在 3D 对象上放置地标选项，包括从 DICOM 文件进行体积渲染、定义和固定有意义的轴、轻松导入、放置、控制和导出地标，以及处理大型数据集。TINA 手动地标定位工具在 Linux 下运行，可以从 http://www.tina-vision.net/tarballs/ 免费获得。
