摘　　要：在数字化X光影像仪中,图像信息是通过医生的视觉来获取的,所以在图像处理中,应充分考虑人眼的视觉特性.从人眼视觉的生理特性和人的心理特性出发,测试分析了图像的灰度分辨能力和图像结构的敏感性.根据测试结果总结了在复杂背景下视觉对目标的分辨能力,建立了相应的数学模型和具体实现方法.将该方法应用于X光图像处理系统中,提高了图像质量,增加了医生诊断的准确性.In a digital X-ray imager, the image information is obtained through human vision, so the visual property of human eye should be fully taken account into image processing. Starting with the physiological property of human eye and human psychological property, both gray resolution of an image and sensitivity of an image structure are investigated and tested. The related regularities for the vision are summarized, the corresponding mathematical model and concrete realizing method are set up according to the tested results. The method has been applied to the practical X-ray image processing systems and the image quality is improved. In this way the accuracy of the doctor diagnosis is improved.
