I wonder if DR and chest radiograph are the same? Which one has more radiation?

Hello, chest X-ray and DR are actually the same, but the imaging technology is different. Chest X-ray passes through the chest and is projected on the film to form chest X-ray, while DR is digital imaging. X-ray photons are directly converted into digital images through electronic cassette, and the radiation to human body is basically the same.

Suggestion:

Whether it is DR or traditional X-ray films, the radiation dose to the human body during examination is very small, and the radiation dose is actually the staff who took the films. If you make a microscopic comparison, the chest radiograph may be slightly larger than Dr.
