Yesterday, I went to the county hospital with my friends for a chest X-ray, but in the end we only got a report and asked the doctor for an X-ray.

At present, chest X-rays are usually DR or CR, and there is basically no need to take X-rays. CR and DR are different from the original imaging methods, and their principles are similar to those of film cameras and digital cameras. When taking chest radiographs, some hospitals do not charge filming fees, while others do, which is related to local policies. If it is the former category, you need to pay extra when you need film, and the latter has film directly, so you don't have to pay any more.
