  • Patent number: 9949703
    Abstract: An x-ray imaging apparatus revolves a digital radiation detector and a radiation source about an imaging area where a subject is positioned to be imaged. A housing encloses the source and the detector, and includes an open housing gap to allow movement of the subject into the imaging area by moving through the open gap. A housing extension may be deployed to close the housing gap and to enclose the detector as it revolves. Shielding assemblies prevent exterior access into the housing.

  • Patent number: 9179886
    Abstract: A method for aligning a radiation source with a portable image receiver in a radiographic imaging system generates a magnetic field with a predetermined field pattern and with a time-varying vector direction at a predetermined frequency from an emitter apparatus that is coupled to the radiation source, wherein the generated magnetic field further comprises a synchronization signal. Sensed signals from the magnetic field are obtained from a sensing apparatus that is coupled to the image receiver, wherein the sensing apparatus comprises three or more sensor elements, wherein at least two of the sensor elements are arranged at different angles relative to each other and are disposed outside the imaging area of the image receiver. An output signal is indicative of an alignment adjustment according to the amplitude and phase of the obtained sensed signals relative to the synchronization signal.

  • Patent number: 9155509
    Abstract: A radiography system for obtaining a radiographic image of a subject has a radiation source energizable to direct radiant energy along a radiation path and an imaging receiver sensitive to the radiant energy for forming the radiographic image. A sensor apparatus is disposed to provide one or more output signals that are indicative at least of centering of the radiation path with respect to the receiver, of an angle of the receiver relative to the radiation path, and of a source-to-image distance along the radiation path. A display apparatus generates, in response to the one or more output signals, a display that indicates the centering of the radiation path with respect to the receiver and that provides one or more values indicative of at least the source-to-image distance and the angle of the receiver relative to the radiation path.
