计算机X线摄影伪影及相应处理

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。

Artifacts found in computed radiography and corresponding disposal

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.Conclusion:If operator can be aware of the causes to result in artifacts,it will be eliminated easily.
