The imagery equipment is one thing, the other is the skill to interpret what you see. Sure, a bad fracture might be obvious but there are many very subtle things that are not so easy to see or understand. The radiographer will know the equipment but will usually have to defer to the Doctor for expert advice. Mobile equipment does exist, however it is usually used at smaller hospitals who don't have the space or money for a permanent unit.
