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.
Claims27
An intra-oral x-ray sensor, comprising:
- circuitry configured to communicate intra-oral x-ray sensor position information to a remote x-ray source;
- circuitry configured to verify an x-ray beam characteristic of an x-ray beam received from the remote x-ray source by the intra-oral x-ray sensor;
- an x-ray image component configured to acquire intra-oral x-ray image information;
- an x-ray backscatter component operably coupled to the x-ray image component;
- wherein the x-ray image component is configured to detect backscattering, and the x-ray backscatter component is configured to modify the intra-oral x-ray image information responsive to one or more inputs from the x-ray image component indicative of the presence of backscatter;
- and
- circuitry configured to communicate an x-ray beam field of view parameter to the remote x-ray source responsive to verifying the x-ray beam characteristic of the x-ray beam received from the remote x-ray source.
An intra-oral x-ray sensor operation method, comprising:
- communicating intra-oral x-ray sensor position information from an intra-oral x-ray sensor to a remote x-ray source, the intra-oral x-ray sensor including an x-ray image component configured to acquire intra-oral x-ray image information and an
- x-ray backscatter component operably coupled to the x-ray image component, wherein the x-ray image component is configured to detect backscattering, and the x-ray backscatter component is configured to modify the intra-oral x-ray image information responsive to one or more inputs from the x-ray image component indicative of the presence of backscatter;
- receiving an x-ray beam from the remote x-ray source with the intra-oral x-ray sensor;
- verifying an x-ray beam characteristic associated with the x-ray beam received from the remote x-ray source;
- and
- communicating an x-ray beam field of view parameter to the remote x-ray source responsive to verifying the x-ray beam characteristic associated with the x-ray beam received from the remote x-ray source.
