How do you know if it’s a DR or a CR film?

The X-ray machine is a device used to emit X-rays. The basic components include tube components, beamers, high-voltage generators, etc.
The imaging method can use traditional CR or DR.
CR, that is, computer X-ray photography, is to receive X-rays through an IP imaging board, and then use a computer to record the data of the IP board.
An imaging method that converts data readings into images.
DR, that is, direct imaging, is a high-tech imaging that directly converts X-rays passing through the human body into images through a flat panel detector
equipment. The images can be directly transferred to the computer through the workstation software, and the pictures can be optimized and edited to help doctors make more accurate diagnosis of the patient’s condition.
The main difference between the two is the imaging equipment used. CR has now been replaced by DR.
