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.
Claims30
An intra-oral x-ray sensor, comprising:
- an x-ray image component configured to acquire intra-oral x-ray image information associated with a patient;
- and
- an intra-oral radiation shield structure configured to reduce at least one of x-ray scattering, transmission, or re-radiation by at least 50%, wherein a portion of the intra-oral radiation shield structure is flexible or jointed so as to conform to a portion of an oral cavity.
An intra-oral x-ray sensor, comprising:
- an x-ray image component configured to acquire intra-oral x-ray image information associated with a patient;
- and
- an intra-oral radiation shield structure configured to reduce at least one of x-ray scattering, transmission, or re-radiation by at least 50%, wherein the intra-oral radiation shield structure includes a composition having a carrier fluid and a plurality of x-ray shielding particles each having at least a first x-ray shielding agent and a second x-ray shielding agent, the second x-ray shielding agent having one or more absorption edges different from the first x-ray shielding agent.
An intra-oral x-ray sensor, comprising:
- an x-ray image component configured to acquire intra-oral x-ray image information associated with a patient;
- an intra-oral radiation shield structure configured to reduce at least one of x-ray scattering, transmission, or re-radiation by at least 50%;
- 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.
