Abstract
Systems, devices, and methods are described for providing, among other things, an intra-oral x-ray imaging system configured to reduce patient exposure to x-rays, reduce amount of scatter, transmission, or re-radiation during imaging, or improve x-ray image quality. In an embodiment, an intra-oral x-ray imaging system includes an intra-oral x-ray sensor configured to communicate intra-oral x-ray sensor position information or intra-oral x-ray sensor orientation information to a remote x-ray source.
Claims66
An intra-oral x-ray imaging system, comprising:
- an intra-oral x-ray sensor configured to acquire intra-oral x-ray image information associated with a patient;
- and
- an x-ray beam limiter assembly including a controllable x-ray collimator module, the controllable x-ray collimator module including an x-ray beam collimation adjustment mechanism responsive to one or more inputs including information associated with a border location of the intra-oral sensor in the mouth of the patient.
