The difference between X-ray and filming.

X-ray photography and fluoroscopy are both X-ray irradiation, but X-ray photography is a short-time irradiation on the negative film, and the imaging method is the same as photography, while fluoroscopy is a long-time X-ray irradiation, which is mainly used for operations such as contrast intubation or physical examination. In terms of radiation dose, fluoroscopy is much more than filming.
