摘　　要：医学Ｘ光病理检查片由于成象条件和显影条件等的限制，病灶图象的衬比（对比度）较低，某些重要的信息被掩盖了，影响医生对病情作出正确诊断。利甲数字图象处理方法选择适当的变换函数，用区域衬比增强方法对医学Ｘ光片进行处理，增强了图象的衬比，使图片中某些肉眼看不清的特征信息显现出来，提高了诊断的准确性。With a digital image processing system and with some suitable transform functions, a local contrast enhancement method is used for processing X-ray films to obtain better contrast of the images and get more diagnostic information that can not be observed by naked eyes. Hence the diagnostic accuracy can be improved.
