Development of a calibration protocol for medical color displays

本研究计划针对医学影像解译中使用的数位彩色显示器所呈现的一致色彩与一致灰度。目前，由于空间分辨率、对比度分辨率和最大亮度不够，通常不能在彩色显示器上观看胸部、骨骼和乳房x线摄影图像。有证据表明，与单色显示相比，彩色显示会对这些图像的诊断准确性产生负面影响。然而，彩色显示器正在迅速进入显示灰度和彩色信息的市场。在病理和远程医疗中，由于病理和皮肤医学图像固有的颜色，需要彩色显示，但是没有有效的方法来可靠地校准这些彩色显示。一种包括灰度和颜色校准方法的彩色显示器校准协议将极大地有利于医学成像。本研究的最终目标是开发和实现这样一个协议。

This research proposal addresses consistent color and consistent grayscale presentation for digital color displays used in medical image interpretation. Currently, radiographic images such as chest, bone, and mammography are usually not viewed on color monitors because the spatial resolution, contrast resolution and maximum luminance are not adequate. Evidence suggests that diagnostic accuracy for these images are affected negatively when displayed on color compared to monochrome displays. Nevertheless, color monitors are quickly entering the market for displaying grayscale and color information. In pathology and telemedicine, color displays are required because of the inherent color in pathology and dermatology images, but there are no validated methods available to reliably calibrate these color displays. A calibration protocol that includes both a grayscale and color calibration methods for color displays would benefit medical imaging greatly. The ultimate goal of this research is to develop and implement such a protocol. After revising the proposal to a duration of 2 years and a budget for a direct cost of $ 250,000 per year (or a total direct-cost of $ 500,000), the overall goal is still Consistent color and grayscale presentation for digital color displays used in medical image interpretation.
