Patent number: 8331536Abstract: A method, system, and apparatus including an x-ray detector unit that includes an anti-scatter grid free of at least one of a top cover and a bottom cover, a flat panel x-ray detector having an x-ray conversion layer, and an integrated anti-scatter grid assembly configured to provide structural support to the anti-scatter grid and to provide mechanical protection to the flat panel x-ray detector. The anti-scatter grid is configured to absorb a plurality of scattered x-rays impinging on the anti-scatter grid while substantially allowing un-scattered x-rays to pass through the anti-scatter grid. The x-ray conversion layer is configured to convert an x-ray into visible light or an electronic signal. The flat panel x-ray detector is fixed relative to the anti-scatter grid such that the anti-scatter grid remains stationary relative to the flat panel x-ray detector during operation of the x-ray detector.Type: GrantFiled: September 18, 2009Date of Patent: December 11, 2012Assignee: General Electric CompanyInventors: Jeffrey Jon Shaw, Kevin Matthew Durocher, Kenneth S.

Publication number: 20080192899Abstract: A process of data calibration and correction is disclosed that utilizes feedback from a temperature sensor of an x-ray detector to isolate or otherwise select an appropriate calibration or correction map that is specific to the temperature of the x-ray detector during data acquisition. The method is also designed to take into account changes in power transients of an x-ray detector between the acquisition of imaging data and the acquisition of offset data. The method is particularly applicable in optimally selecting and applying gain correction, conversion factor, bad pixel, and offset calibrations.Type: ApplicationFiled: February 12, 2008Publication date: August 14, 2008Inventors: Kenneth S.

Patent number: 7177455Abstract: A method includes obtaining a first image of a subject at a first position, changing a position between the detector and the subject, obtaining a second image, and pasting the first and images to obtain a composite image. The first image and the second image may have an amount of overlap equal to no more than about 30 percent of a field of view of the detector in a direction of movement between the first image and the second image, and, according to some embodiments, may have an overlap of about 4 percent to about 16 percent. This may, in some embodiments, amount to an amount of overlap of about 1.5 cm to about 6.5 or 12 cm. In some embodiments, the span of overlap of the images is at least about 30 cm. The geometry of the images may be used to help paste the images together appropriately.Type: GrantFiled: January 25, 2005Date of Patent: February 13, 2007Assignee: General Electric CompanyInventors: Richard J.

Patent number: 7139417Abstract: The present technique involves remote processing and comparison of medical diagnostic images obtained over a period of time. A remote processing system is provided to match and subtract the medical diagnostic images, which may be received from users and gathered from remote image storage systems. Users are able to interact with the remote processing system through uniform interfaces, which may be disposed at medical institutions to provide platform independent interaction with, and remote processing by, the remote processing system. The technique also uses compression routines to facilitate network transfers of images between the uniform interface and the remote processing system.Type: GrantFiled: August 14, 2001Date of Patent: November 21, 2006Assignee: GE Medical Systems Global Technology Company LLCInventors: Francois S.

Patent number: 7127032Abstract: A method and system of electronically detecting and measuring gravitational loads placed on an x-ray detector is disclosed. An x-ray detector incorporates an accelerometer that detects and provides an output as to the extent of gravitational loads or forces placed thereon. The accelerometer may also time and/or date stamp each recorded event such that a technician may determine when the x-ray detector was subjected to a particular load. A microcontroller/microprocessor may also compare a current reading of the accelerometer to a threshold and, based on the comparison, provide an audio or visual indication that the x-ray detector has been subjected to a potentially damaging gravitational load.Type: GrantFiled: April 21, 2006Date of Patent: October 24, 2006Assignee: General Electric CompanyInventor: Kenneth S.

Patent number: 6944265Abstract: A device for use in image pasting is described. The device includes a digital x-ray detector capable of automatic digital imaging without the use of an image intensifier; the detector preferably being a flat-panel detector. Additionally, an image pasting system using a solid-state detector is described. The system can connect the detected images to a display via a network (such as a WAN, a LAN, or the internet). Further, an image geometry measurement device for use in pasting x-ray images is disclosed. The geometry measurement device helps determine the relative position of two images to be used in image pasting. This information can be used alone, or in connection with an image pasting algorithm. Still further, methods of forming composite images are disclosed using a flat-panel detector and using the geometry of the images. The disclosed devices and systems can be integrated with other digital image pasting technology.Type: GrantFiled: November 25, 2002Date of Patent: September 13, 2005Assignee: GE Medical Systems Global Technology Company, LLCInventors: Richard J.

Patent number: 6795526Abstract: A method and system for of defining, or identifying, regions of interest for exposure management in a digital x-ray imaging system, and especially in the case of multiple consecutive image acquisitions. According to the most basic embodiment of the present invention, simple geometric shapes arranged in a matrix configuration are used to aid an operator in identifying a region of interest for a diagnostic x-ray image. Each region of interest is selectable from a low-dose preshot image and may be corrected, or processed, in order to enhance the results of a subsequent diagnostic image. The processing of the preshot image allows the system to automatically make predictions for the diagnostic image exposure requirements, thereby avoiding unnecessary multiple images.Type: GrantFiled: March 4, 2002Date of Patent: September 21, 2004Assignee: GE Medical Systems Global Technology Co., LLCInventors: Kenneth S.

Publication number: 20020181661Abstract: An x-ray system (10) include a digital detector (400) that defines two regions: a first region (404) suitable for generating data useful for creating a patient x-ray image and a second region (406) less suitable for generating such data than the first region. A source (20) transmits x-rays through a phantom (420) located between the source and the second region (406) so that the detector (400) generates test data in the second region. A processor (302) measures at least one parameter in response to the test data and stores a value of the parameter at one point of time. The processor compares the first value with a second value of the one parameter generated at a later second point in time. The processor also generates a result signal representing the results of the comparison.Type: ApplicationFiled: June 5, 2001Publication date: December 5, 2002Inventors: Habib Vafi, Farshid Farrokhnia, Donald F.
