Patent number: 9629591Abstract: An X-ray imaging system includes a digital X-ray detector configured to acquire X-ray image data without communication from a source controller and to send the X-ray image data to a portable detector control device for processing and image preview. The source controller is configured to command X-ray emissions of X-rays from an X-ray radiation source for image exposures.Type: GrantFiled: January 21, 2011Date of Patent: April 25, 2017Assignee: GENERAL ELECTRIC COMPANYInventors: James Zhengshe Liu, Paul Richard Granfors, Kenneth Scott Kump, Ping Xue, Donald Fayette Langler, Brian John Kost

Patent number: 8779907Abstract: A control circuit for a portable x-ray medical imaging system detector. The control circuit operates to reduce power consumption of the portable x-ray detector. The detector control circuit includes a multi-function switch coupled to the portable detector, and a detector control module installed in the portable detector, the detector control module receiving an input from the multi-function switch and based on the received input reconfiguring the portable detector from a first operational mode to a different second operational mode. A portable detector including the detector control circuit and a method of operating the portable detector are also provided.Type: GrantFiled: August 31, 2009Date of Patent: July 15, 2014Assignee: General Electric CompanyInventors: James Zhengshe Liu, Scott William Petrick, Donald Fayette Langler, Gary Vernon McBroom, Roy Allan Schley

Patent number: 8768035Abstract: A method for processing X-ray image data includes exposing a digital detector to X-ray radiation. The method also includes sampling data via the digital detector including X-ray image data and offset image data. The method further includes calculating an average offset image without prior knowledge of a total number of offset image frames sampled.Type: GrantFiled: April 27, 2011Date of Patent: July 1, 2014Assignee: General Electric CompanyInventors: James Zhengshe Liu, Paul Richard Granfors, Kenneth Scott Kump, Ping Xue, Donald Fayette Langler, Brian John Kost

Patent number: 8576986Abstract: An X-ray imaging method includes in a digital X-ray detector including an array of discrete picture elements each including a photodiode and a transistor, applying a first voltage to the transistors of the discrete picture elements. The method also includes preparing for acquisition of X-ray image data by sampling data from the discrete picture elements while applying a second voltage to the transistors of the discrete picture elements not then being sampled, the second voltage being more negative than the first voltage. The method further includes receiving X-ray radiation on the detector from a source. The method yet further includes sampling X-ray image data from the discrete picture elements while applying the second voltage to the transistors of the discrete picture elements not then being sampled.Type: GrantFiled: January 21, 2011Date of Patent: November 5, 2013Assignee: General Electric CompanyInventors: James Zhengshe Liu, Paul Richard Granfors, Kenneth Scott Kump, Ping Xue, Donald Fayette Langler, Brian John Kost

Patent number: 8396188Abstract: An X-ray imaging method includes performing an X-ray exposure via an X-ray radiation source responsive to a source controller. The method also includes sampling X-ray image data via a digital detector without communication of timing signals from the source controller. The method further includes combining the sampled X-ray image data of at least one imaging frame or two or more imaging frames with at least one of the frames spanning a duration in which the exposure occurred, to produce X-ray image data capable of being reconstructed into a user-viewable image.Type: GrantFiled: January 21, 2011Date of Patent: March 12, 2013Assignee: General Electric CompanyInventors: James Zhengshe Liu, Paul Richard Granfors, Kenneth Scott Kump, Ping Xue, Donald Fayette Langler, Brian John Kost
