Why do artifacts appear in images from DR X-ray machines?

Artifacts will appear in the images of DR X-ray machines, mainly due to the following reasons:
1. Radiation with uneven quality: If the radiation quality is uneven, the digital image will have uneven light and dark areas, which will lead to the generation of artifacts.
2. Artifact filter: Digital image processors often use filters to reduce noise, but improper use of filters may lead to the generation of artifacts.
3. Spatial resolution difference: Digital radiographic images are different from traditional radiographic images. Digital radiographic images are more detailed in pixel density. Therefore, if there is a spatial resolution difference, artifacts may result.
4. Machine failure: Failure in the DR X-ray machine may also lead to the generation of artifacts.
5. Human factors: Artifacts can also be caused if the operator accidentally causes the machine to move unsteadily or underexpose.
