Most medical images are presented in two dimensions by intensity on a film or electronic media such as video. The display process of transforming the recorded image into a viewable image on these media fails to transmit some or much of the useful information in the recorded image. We propose research to improve this information transfer in the 2D display process. To achieve this improvement, we will accomplish the following objectives: (1) Develop and prove a methodology for standardizing the display system so that, independent of the display device, changes in display driving intensity produce a predictable perceptual result, and one that optimizes the effect of contrast enhancement methods designed to maximally transmit diagnostic information. (2) Determine the display scale sensitivity that is optimal for presentation of medical images or classes of medical images, as a function of target sharpness and signal to noise ratio. (3) Study the effect of image structure on the contrast required for feature discrimination in medical images. This study will not only produce results necessary for achieving the other objectives, but it will also develop further understanding of the process of perception of medical images that can lead to other improvements in imaging, processing, and display.

大多数医学图像在胶片上按强度以二维方式呈现 或视频等电子媒体。 变换的显示过程 将图像录制到这些媒体上的可视图像中无法传输某些内容 或记录图像中的许多有用信息。 我们建议 研究改善二维显示过程中的信息传输。 为了实现这一改进，我们将实现以下目标： (1) 开发并证明一种标准化显示系统的方法，以便 独立于显示设备，显示驱动的变化 强度产生可预测的感知结果，并且可以优化 旨在最大限度地传输对比度增强方法的效果 诊断信息。 (2) 确定最适合的显示刻度灵敏度 将医学图像或医学图像类别表示为函数 目标清晰度和信噪比。 (3)研究图像结构对所需对比度的影响 医学图像中的特征歧视。 这项研究不仅会产生 实现其他目标所必需的结果，但它也将 加深对医学认知过程的理解 图像可以带来成像、处理和其他方面的改进 展示。
