A scoring system using computerised analysis of digital stored images of knee radiographs has been developed. Measurement is based on the assessment of joint space size. It is sensitive, rapid, and reproducible. Plain radiographs are positioned on an acetate grid; a computer generated grid is superimposed on a digital image of the radiograph viewed on a closed circuit television monitor and the joint space measured automatically. Area and distance have been assessed; area measurements are more reproducible. Application of microcomputer based digital image analysis to radiological scoring systems is an important step in understanding the nature and progression of arthritis.
一种利用计算机对膝关节X线片数字存储图像进行分析的评分系统已被开发出来。测量基于关节间隙大小的评估。它灵敏、快速且可重复。普通X线片放置在醋酸纤维网格上；计算机生成的网格叠加在闭路电视监视器上显示的X线片数字图像上，关节间隙自动测量。已对面积和距离进行了评估；面积测量的重复性更好。将基于微型计算机的数字图像分析应用于放射学评分系统是理解关节炎本质和进展的重要一步。
