  • Publication number: 20230371912
    Abstract: A radiographic imaging system may be deployed in an ICU unit of a medical facility that may benefit from isolating patients and health care providers. The radiography system provides a plurality of patient beds each having a digital radiographic detector positioned therein. An x-ray source is operable to be selectively positioned relative to each of the patient beds using a remote control system. The remote control system also controls firing of the x-ray source.

  • Publication number: 20230027305
    Abstract: Radiographic imaging identifies a subject anatomy for radiographic image content and automatically identifies a subject’s position from one or more sensor signals. The imaging apparatus issues re-positioning guidance signals for re-positioning the patient. Signals are generated to set an imaging exposure technique and component positions according to data associated with the subject anatomy. A radiographic image of the subject is acquired according to the component and technique signals by automatically energizing the x-ray source. The acquired radiographic image is analyzed using trained logic to determine clinical diagnostic suitability of the image and to identify one or more abnormalities in the subject anatomy.

  • Publication number: 20220409146
    Abstract: A plurality of radiographic images are captured of a portion of a patient in periodic motion, such as cardiac images (heartbeat motion) or lungs (breathing motion). A first subset of the captured radiographic images are identified as having a common first capture time relative to a phase of the periodic motion. A first 3D image is reconstructed using the first subset of captured radiographic images. Additional subsets of the radiographic images are processed similarly based on their common capture time relative to the phase of the periodic motion.

  • Patent number: 10307115
    Abstract: A system for cone beam computed tomography of an extremity has an x-ray source and a digital radiographic detector both revolved about a central imaging axis so that the detector moves at least partially around a first extremity of a patient and, if the extremity is the leg of the patient, the detector moves between the legs of the patient. The detector path has a radial distance less than that of the source path. A housing that encloses the source and detector includes a pivoting door to allow sideways access for the patient's leg to be placed at the central imaging axis.
