本文介绍了正在进行的研究交互式体积可视化与体积分析工具。为了建立一个易于使用的应用程序，三维可视化已被嵌入到最先进的远程放射学系统，其中额外的功能往往是需要超出基本的图像传输和管理的状态。主要的临床需求，衍生空间措施的工具，以实现扩展的诊断支持和治疗计划。介绍了一个通用的插件机制，这项工作示范性地描述了一个批准的应用程序的有用的扩展。交互式可视化是通过一种混合的方法来实现的，该方法利用了基于海德堡光线跟踪模型的精确体积可视化和现代工作站的图形加速能力。几种用于体积分析的工具扩展了三维视图。它们由适当的输入设备控制，以选择数据体积中的位置，测量解剖结构或启动分割过程。此外，可以连接触觉接口以在三维重建内导航时提供更真实的反馈。这项工作与心脏、肝脏和头部外科领域的研究密切相关。通过与我们的医疗合作伙伴的合作，所提供的工具的开发有助于将图像分析集成到临床常规中。
This paper describes ongoing research concerning interactive volume visualization coupled with tools for volumetric analysis. To establish an easy to use application, the three-dimensional-visualization has been embedded in a state of the art teleradiology system, where additional functionality is often desired beyond basic image transfer and management. Major clinical requirements for deriving spatial measures are covered by the tools, in order to realize extended diagnosis support and therapy planning. Introducing a general plug-in mechanism, this work exemplarily describes the useful extension of an approved application. Interactive visualization was achieved by a hybrid approach taking advantage of both the precise volume visualization based on the Heidelberg raytracing model and the graphics acceleration capabilities of modern workstations. Several tools for volumetric analysis extend the three-dimensional-viewing. They are controlled by adequate input devices to select locations in the data volume, measure anatomical structures or initiate a segmentation process. Moreover, a haptic interface can be connected to provide a more realistic feedback while navigating within the three-dimensional-reconstruction. The work is closely related to research in the field of heart, liver and head surgery. In cooperation with our medical partners the development of tools as presented facilitates the integration of image analysis into the clinical routine.
