Is X-ray photography just analog photography?

Not just analog photography. X-ray photography is not only analog photography, but also digital imaging. Computer X-ray photography is the first digital technology applied to radiography, and it is an advanced X-ray machine formed by combining computer digital image processing technology with X-ray radiation technology. On the basis of the original diagnostic X-ray direct film imaging, the real-time image is digitally processed by A/D conversion and D/A conversion, and then the image is digitized. Its appearance broke the concept of traditional X-ray machine and realized the transformation from analog X-ray image to digital X-ray image. Digital image is superior to traditional X-ray imaging in displaying bone structure, articular cartilage and soft tissue, and quantitative analysis of mineral salt content is also feasible.
