Our program involves the means of presentation of medical images from a wide range of modalities. The research, consisting of six projects, concern 3D and 2D display for diagnosis and for planning of radiotherapy. For 3D display we will investigate methods for fast, interactive 3D visualization of medical image information, directly from the image intensity data. We will also investigate a number of approaches for visualizing the spatial relationships among 3D information from two imaging modalities. Qualitative clinical evaluation will support these investigations. Object definition methods that operate in both 2D and 3D and which are based on multiresolution image descriptions will be developed, so as to support the 3D display investigation. Here evaluation will be based on the time to produce an accurate definition of an object of clinical interest. For 2D display we will investigate contrast enhancement, workstation design for effective navigation through large image sets, and fundamental aspects of visual perception of contrast in grey-scale images, leading to effective display. The visual perception research will focus on the relation of an image's spatial structure on the perception of contrast in that image. The contrast enhancement technique of contrast-limited adaptive histogram equalization will be investigated for a wide range of clinical applications, and it will be heavily evaluated and improved for radiotherapy treatment applications. The workstation research will compare the use of traditional and electronic means of display and will develop prototype workstation functions. Controlled observer studies will form the basis of all the 2D perception and display research.

我们的计划涉及医疗表现的手段， 来自各种模式的图像。 研究，包括 在六个项目中，涉及用于诊断的3D和2D显示， 放疗计划。 对于3D显示，我们将研究快速，交互式 医学图像信息的三维可视化，直接从 图像强度数据。 我们还将调查一些 3D空间关系的可视化方法 来自两种成像模式的信息。 定性临床 评价将支持这些调查。 对象定义 在2D和3D中操作并且基于 将开发多分辨率图像描述，以便 支持3D显示调查。 评价将在 基于产生物体精确定义的时间 临床感兴趣。 对于2D显示，我们将研究对比度增强， 用于在大图像中有效导航工作站设计 集合，以及对比度视觉感知的基本方面， 灰度图像，导致有效显示。 视觉 感知研究将集中在图像的关系， 空间结构对图像中对比度的感知。 的 对比度受限自适应对比度增强技术 直方图均衡化将被研究用于广泛的 临床应用，它将被大量评估， 改进了放射治疗应用。 的 工作站研究将比较传统和 电子显示手段，并将开发原型 工作站功能。 对照观察员研究将构成 所有2D感知和显示研究的基础。
