The time-of-flight (ToF) technique is an emerging technique for rapidly acquiring distance information and is becoming increasingly popular for intra-operative surface acquisition. Using the ToF technique as an intra-operative imaging modality requires seamless integration into the clinical workflow. We thus aim to integrate ToF support in an existing framework for medical image processing.
MITK-ToF was implemented as an extension of the open-source C++ Medical Imaging Interaction Toolkit (MITK) and provides the basic functionality needed for rapid prototyping and development of image-guided therapy (IGT) applications that utilize range data for intra-operative surface acquisition. This framework was designed with a module-based architecture separating the hardware-dependent image acquisition task from the processing of the range data.
The first version of MITK-ToF has been released as an open-source toolkit and supports several ToF cameras and basic processing algorithms. The toolkit, a sample application, and a tutorial are available from http://mitk.org.
With the increased popularity of time-of-flight cameras for intra-operative surface acquisition, integration of range data supports into medical image processing toolkits such as MITK is a necessary step. Handling acquisition of range data from different cameras and processing of the data requires the establishment and use of software design principles that emphasize flexibility, extendibility, robustness, performance, and portability. The open-source toolkit MITK-ToF satisfies these requirements for the image-guided therapy community and was already used in several research projects.
飞行时间（ToF）技术是一种快速获取距离信息的新兴技术，在术中表面获取方面越来越受欢迎。将 ToF 技术用作术中成像模式需要无缝集成到临床工作流程中。因此，我们旨在将 ToF 支持集成到现有的医学图像处理框架中。
MITK-ToF 作为开源 C++医学成像交互工具包（MITK）的扩展实现，为快速原型设计和开发利用术中表面获取的距离数据的图像引导治疗（IGT）应用程序提供了基本功能。该框架采用基于模块的架构设计，将硬件相关的图像采集任务与距离数据的处理分离。
MITK-ToF 的第一个版本已作为开源工具包发布，支持多个 ToF 相机和基本的处理算法。该工具包、示例应用程序和教程可从 http://mitk.org 获取。
随着 ToF 相机在术中表面获取方面的日益普及，将范围数据支持集成到医学图像处理工具包（如 MITK）中是必要的一步。处理来自不同相机的范围数据采集和数据处理需要建立和使用强调灵活性、可扩展性、鲁棒性、性能和可移植性的软件设计原则。开源工具包 MITK-ToF 满足图像引导治疗社区的这些要求，并已在多个研究项目中使用。
