Welcome to the National Library of Medicine **Insight  Segmentation and Registration Toolkit (ITK)**（http://www.itk.org/）.  ITK is an open-source, cross-platform system  that provides developers with an extensive suite of software tools for image  analysis.  Developed through extreme  programming methodologies, ITK employs leading-edge algorithms for registering  and segmenting multidimensional data. The goals for ITK include:

• Supporting the Visible Human Project.

• Establishing a foundation for future research.

• Creating a repository of fundamental algorithms.

• Developing a platform for advanced product development.

• Support commercial application of the technology.

• Create conventions for future work.

• Grow a self-sustaining community of software users and developers.

ITK的配置过程与配置VTK的时候大体相同，在这就不做详细说明了。可参考之前的VTK的配置流程。

配置好ITK后，编译Example/Installation下的HelloWorld程序，其运行结果如下所示：

接下来，可详细阅读下ITK官方提供的Documentation了。
