MEDICAL IMAGE PRESENTATION

我们的节目继续调查医疗报告的呈现方式 来自各种成像方式的图像。这项研究，涉及 六个项目和两个核心，涉及技术和临床应用 三维和二维显示，用于诊断和放射治疗计划。 对物体定义和人类视觉的研究开发了模型和 支持显示技术发展的方法。 在3D显示领域，1)我们将开发3D勘探技术 医学图像数据和用于可视化的复杂组合 解剖和规划对象，以及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展示工作中，1)我们 将评估乳房X光照相对比度改善的诊断用途， 放射治疗门户和CT胸部图像，以及b)我们将开发和 在现场和现场评估临床可用的诊断工作站 实验室，用于多种检查和乳房X光检查。我们的 人类视觉项目和我们的对象定义项目将专注于形状- 和基于分组的复杂情境中的感知和分析 在医学图像中发现，并将产生形状的视觉模型。这个 对象定义项目将包括交互式3D应用程序 放射治疗门户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价。 统计核心不仅将为以下方面提供设计和数据分析 观察者实验，也是改进的统计或 在相关观察的小样本观察者研究中的分析， 无论是在感知能力被评级的地方，还是在给出连续回答的地方。 研究结果将允许较小的样本提供有保证的类型 I错误率和统计能力。 设施核心将支持软件和硬件设施， 管理和人体工程学咨询。

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.
