Compared with dr photography, cr photography.

Compared with dr photography, cr photography takes longer and the definition is not as high as DR photography.

Because DR belongs to direct digital photography, it can be directly imaged, and the imaging speed is relatively fast. Generally, it can be completed in 26 seconds without special processing. CR needs to be processed and belongs to indirect imaging. Therefore, compared with CR, DR shortens the examination time and improves the quality of service, so DR is used more in clinic, which shortens the waiting time of patients.
