Our program continues to investigate means of presentation of medical images from a wide range of imaging modalities. The research, involving six projects and two cores, concerns techniques and clinical applications of 3D and 2D display for diagnosis and the planning of radiotherapy. Investigations into object definition and human vision develop models and methods supporting display technique development. In the 3D display area, 1) we will develop techniques for 3D exploration of medical image data and for visualization of complicated combinations of anatomy and planning objects, and 2) we will investigate 3D display applications in radiotherapy and pathology. In our 2D display work, 1) we will evaluate diagnostic uses of contrast improvements of mammographic, radiotherapy portal, and CT chest images, and b) we will develop and evaluate clinically usable diagnostic workstations in the field and in the laboratory, for both multimodality and mammographic display. Both our human vision project and our object definition project will focus on shape- and grouping-based perception and analysis in the complicated contexts found in medical images and will produce models of vision of shape. The object definition project will include application in both interactive 3D display and automatic, on-line analysis of radiotherapy portal images. Controlled evaluations will be conducted in all of the project areas. A statistics core will not only provide designs and data analyses for observer experiments but also development of improved statistics or analyses in observer studies with small samples of correlated observations, both where perceivability is rated and where continuous responses are give. The research results will allow smaller samples to provide guaranteed type I error rates and statistical power. A facilities core will support software and hardware facilities, administration, and ergonomic consultation.

我们的计划继续研究医疗的呈现方式 来自多种成像方式的图像。 该研究涉及 六个项目两个核心，涉及技术和临床应用 用于诊断和放射治疗规划的 3D 和 2D 显示。 对物体定义和人类视觉的研究开发模型和 支持显示技术开发的方法。 在3D显示领域，1）我们将开发3D探索技术 医学图像数据以及复杂组合的可视化 解剖和规划对象，2) 我们将研究 3D 显示 在放射治疗和病理学中的应用。 在我们的 2D 显示工作中，1）我们 将评估乳房X光造影对比改进的诊断用途， 放射治疗门户和 CT 胸部图像，b) 我们将开发和 评估现场和现场临床可用的诊断工作站 实验室，用于多模态和乳腺X线摄影显示。 我们的 人类视觉项目和我们的对象定义项目将重点关注形状 以及复杂情境中基于分组的感知和分析 在医学图像中发现并将产生形状视觉模型。 这 对象定义项目将包括交互式 3D 中的应用 放射治疗射野图像的显示和自动在线分析。 将在所有项目领域进行受控评估。 统计核心不仅提供设计和数据分析 观察者实验，还开发改进的统计数据或 观察者研究中对相关观察结果的小样本进行分析， 既可以对可感知性进行评级，又可以给出连续的响应。 研究成果将为更小的样本提供有保证的类型 I 错误率和统计功效。 设施核心将支持软件和硬件设施， 管理和人体工程学咨询。
