CR图像处理窗技术研究

目的：提高计算机X线摄影（Computed Radiography，CR）的质量和工作效率。材料与方法：收集我科1000例病人胸部、脊椎、骨盆、四肢关节的CR图像效果的临床应用及探讨。结果：1000例采集病人CR图像男性487例，女性513例，其中儿童63例，系统计算机与X线摄影结合起来系一种新的成像方法，优点为减少X线曝光剂量使病人受照射剂量降低至更安全，并有强大的图像后处理功能。窗技术应用提高胶片质量及工作效率。结论：CR数字图象在临床运用中与技师投照技术，印板选择，图象的缩小放大以及窗宽（window width，WW）、窗位（Window level，WC）的调节有关，并可总结出参考数据。

Study to Window Setting Technique in CR Image Maniqulation

Purpose:To promote quality and work efficiency of computed radiology.Materials and Methods:Analysis the clinical application of 1000 cases CR images which of chest,vertebrae,pelvis and four limbs were performed by our department.Results:There are 1000 cases CR images were received CR exam.among the total,man in 487,female in 513,children in 63.It is a new imaging method that combine radiology with computer.Its preponderances are that the patients are more safety due to reduce X-ray dose,powerful image postp...
