The Insight Toolkit, Version 4 (Pennsylvania)

1999年，NLM高性能计算和通信办公室授予了多份合同，以组建一个软件开发联盟，创建和开发一个应用程序编程接口（API），并首次实现一个分段和注册工具包，随后命名为Insight Toolkit（ITK）。最初的奖项包括六个承包商：通用电气全球研究，洞察力，公司，Kitware，Inc.，位于查佩尔山的北卡罗来纳州大学、宾夕法尼亚大学和田纳西大学。这六个承包商与五个分包商合作：哈佛大学医学院、宾夕法尼亚大学、匹兹堡大学、哥伦比亚大学和犹他州大学。最初的ITK奖项的表演期从1999年开始，到2003年结束。由此产生的系统最初是为了计算机辅助探索国家医学图书馆（NLM）可见人（VHP）数据集。该小组的最终成果是一个专注于分割和配准算法的开源软件库，直接插入公共领域，现在有助于支持全球图像分析和其他领域的研究。ITK等开放源代码倡议通过提供进行高级调查所需的软件基础设施的基础，有助于降低进入复杂研究领域的门槛。修订ITK被认为是通过软件对国家基础设施的贡献。我们仔细考虑了该软件的培养和维护，向开发人员保证该软件将继续支持新版本，错误修复和持续增长。Insight Toolkit（ITK）目前随ITK 3.16版本发布，该版本于2009年9月发布（参见URL：http://www.itk.org）。尽管通过系统技术合同继续提供支持，但NLM希望此时重新审视ITK的基本设计和软件架构。ITK的初步设计会议于1999年11月初举行，虽然该软件的设计决定是针对2004年的预期技术，但这些决定现在已经过时。

In 1999, the NLM Office of High Performance Computing and Communications awarded multiple contracts for the formation of a software development consortium to create and develop an application programmer interface (API) and first implementation of a segmentation and registration toolkit, subsequently named the Insight Toolkit (ITK). The original awards included six contractors: GE Global Research, Insightful, Inc., Kitware, Inc., the University of North Carolina at Chapel Hill, the University of Pennsylvania, and the University of Tennessee. The six contractors were partnered with five subcontractors: Harvard University Medical School, the University of Pennsylvania, the University of Pittsburgh, Columbia University, and the University of Utah. The period of performance for the original ITK awards began in 1999 and ended in 2003. The resulting system was originally intended for computer-assisted exploration of the National Library of Medicine (NLM) Visible Human (VHP) data sets. The final deliverable for this group was an open-source software library concentrating on segmentation and registration algorithms, directly inserted into the public domain that now helps support research worldwide in image analysis and in other domains. Open-source initiatives such as ITK help to lower the barriers to entry in complex research fields by providing the foundations of the software infrastructure necessary to conduct advanced investigations. Revising ITK is considered a contribution to the nation's infrastructure through software. Careful thought has been placed on the cultivation and maintenance of this software, assuring developers that the software will remain supported with new releases, bug fixes, and continuing growth. The Insight Toolkit (ITK) is currently available with the release, ITK version 3.16, announced in September 2009 (see the URL: http://www.itk.org). Despite continued support through systems technology contracts, NLM wishes to revisit the underlying design and software architecture for ITK at this time. The initial design meeting for ITK was held in early November 1999, and while the design decisions for this software were targeted for the anticipated technology of 2004, those decisions are now showing their age.
