Patent number: 11103205Abstract: A method of operating a mobile fluoroscopic imaging system includes positioning an x-ray source and a DR detector about a patient. Data defining a spatial configuration of the x-ray source and the collimator is stored in the system. The system is configured to determine a source-to-image distance of the x-ray source and the DR detector including by activating the x-ray source and capturing a scout image in the DR detector. Dimensions of the scout image are calculated and the source-to-image distance is determined based on the data defining the spatial configuration of the x-ray source and the collimator and on the dimensions of the scout image.Type: GrantFiled: March 26, 2018Date of Patent: August 31, 2021Assignee: Carestream Health, Inc.Inventors: Dennis J. O'Dea, Xiaohui Wang, Samuel Richard, Michael Ficarra, Joseph E. Stagnitto, Michael C. Lalena, Kenneth J. Brown

Patent number: 9179886Abstract: 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.Type: GrantFiled: August 22, 2014Date of Patent: November 10, 2015Assignee: Carestream Health, Inc.Inventors: Joseph E.

Patent number: 9155509Abstract: 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.Type: GrantFiled: July 31, 2014Date of Patent: October 13, 2015Assignee: Carestream Health, Inc.Inventors: Michael C.
