Patent number: 10677939Abstract: Improvement of the dynamic range of a radiation detector is described. In one embodiment, one or more non-destructive readout operations are performed during a radiation exposure event to acquire data used to improve the dynamic range of the detector. In one implementation, one or more non-destructive readouts of pixels are performed prior to saturation of the pixels during an X-ray exposure so as to obtain non-saturated measurements at the pixels. In an additional implementation, non-destructive readouts of pixels are performed between exposure events so as to obtain an estimate of electronic noise during a multi-exposure examination.Type: GrantFiled: October 29, 2015Date of Patent: June 9, 2020Assignee: GENERAL ELECTRIC COMPANYInventors: Biju Jacob, Hao Lai, Remy Andre Klausz, John Eric Tkaczyk

Patent number: 10568599Abstract: According to some embodiments, a method and a system to create a medical image are disclosed. The method comprises receiving a plurality of patient tissue images during an x-ray dose. Furthermore, during the x-ray dose, a determination is made if motion occurred in the plurality of patient tissue images. In a case that no motion is determined, a diagnostic image of the patient tissue comprising the plurality of patient tissue images is created.Type: GrantFiled: November 16, 2016Date of Patent: February 25, 2020Assignee: GENERAL ELECTRIC COMPANYInventors: Biju Jacob, Remy Andre Klausz, John Eric Tkaczyk, Emad Abutabanjeh

Patent number: 10568694Abstract: A method and system for performing a biopsy guided by a 3D image of the object obtained from digital tomosynthesis is performed. The method includes applying a compression paddle to an object; performing a tomosynthesis scan; reconstructing at least a portion of the scan; locating a lesion using a displayed or reprojected marker to determine a location of the lesion; correlating the location of the lesion in the scan to a marker on the compression paddle or tool holder; and proposing a needle entry point of a biopsy tool based off of the correlation so that a needle or penetration device will effectively reach the lesion or target if it is inserted at the proposed entry point. A system for performing a biopsy is further disclosed.Type: GrantFiled: April 22, 2015Date of Patent: February 25, 2020Assignee: GENERAL ELECTRIC COMPANYInventors: Giovanni John Jacques Palma, Remy Andre Klausz

Patent number: 9898840Abstract: A method of continuous motion digital tomosynthesis includes exposing an object to a programed intensity x-ray beam as an x-ray source travels a pre-determined path, accumulating a signal charge from the x-ray beam, recording the accumulated signal charge into a digital frame image representing raw baseline data, acquiring information on the source's and the detector's position when the recording occurs, compressing the raw baseline data into compressed views, where each respective compressed view is formed by combining the raw data readouts of the respective compressed view, and reconstructing a volumetric breast image by processing each respective compressed view with a reconstruction process function that incorporates the acquired position information and a spatial sampling corresponding to the compressed views. A system configured to implement the method and a computer-readable medium are also disclosed.Type: GrantFiled: May 15, 2014Date of Patent: February 20, 2018Assignee: General Electric CompanyInventors: Remy Andre Klausz, John Eric Tkaczyk, Henri Souchay, Scott Stephen Zelakiewicz
