The difference between photographic bed and remote control bed

Diagnostic bed should mean that the fluoroscopy radiation is large, and the sensitive screen accepts it, but most dynamic images have a small field of view (for example, chest X-rays can't see the whole lung field), so they are generally not produced and are cheap.

Photography is a small radiation, using film, IP board (CR) or receiver (DR), with film, wide field of vision and high image definition.
