U.S. doctor here. I think "ownership" is not the correct way of thinking about this. I would argue that "access" is the better concept. If a dentist creates an xray in his office, then she should have access to the image to be able to prove that she provide standard-of-care treatment should claims of malpractice be leveled. A patient of this dentist should also have ready access to this as it is their body and their information. And perhaps an insurance company may require that they have the right to access the image and ensure the dentist is no submitting fraudulent charges. And many more examples could be created. Throw in privacy considerations adds yet another wrinkle. Again, I think "ownership" or "copyright" is not the best concept.
