摘　　要：目的:系统完整分析计算机X线摄影伪影,并寻求解决方法有效避免其再次发生。方法:收集各类伪影图像,并按照与成像过程的关联程度进行划分归类。结果:造成伪影出现的原因包括成像板因素、影像读取装置因素、图像后处理、激光打印机原因、操作者错误。结论:如果操作员能够认知产生伪影的原因,就能有效的消除。Objective：To systematically analyze artifacts found in computed radiography and obtain the effective means to avoid them. Methods：To collect various kinds of images with artifacts and classify them in terms of concerning with the imaging flow. Results： The causes producting artifacts were involved in imaging plate, imaging reader, imaging process, laser printer, operator errors. Condusion： If operator can be aware of the causes to result in artifacts, it will be eliminated easily.
