  • Patent number: 7963697
    Abstract: A gain correction and calibration technique for digital imaging systems is provided. In one embodiment, a method may include acquiring a plurality of dark images via a digital detector of an X-ray system. Acquiring the plurality of dark images may include acquiring data from a plurality of data channels of the digital detector during an analog test mode of the digital detector in which calibration voltages are applied to the data channels. The method may also include calibrating a channel gain map of the detector based on the plurality of dark images. Additional systems, methods, and devices are also disclosed.

  • Publication number: 20100111263
    Abstract: Systems, methods and apparatus are provided through which in some implementations a portable digital X-ray detector includes a modular handle that is removeable from a housing of the detector, the modular handle includes component(s) that perform functions that are specific to a number of portable digital X-ray detectors, such as data communication with external devices and/or power conditioning, and the housing of the detector includes the pixel array and component(s) that perform functions that are common to the pixel array. In some implementations, the modular handle includes an interface to the housing to support data communications and/or power supply with the component(s) in the housing and the housing also includes an interface that operably couples to the modular handle.

  • Publication number: 20070223654
    Abstract: Systems, processes and apparatus are described through which non-destructive imaging is achieved, including a process for variable binning of detector elements. The process includes accepting input data indicative of image quality goals and descriptors of an imaging task, as well as parameters characterizing a test subject, relative to non-destructive imaging of an internal portion of the test subject and determining when the non-destructive imaging system is capable of achieving the image quality goals using binning of more than four pixels.

  • Publication number: 20070102643
    Abstract: Certain embodiments of the present invention provide for an imaging system including an index value source, a transmitter, a receiver, and an image processing component. The index value source is capable of generating an index value. The index value source is part of and/or included in an imaging system detector. The transmitter is in communication with the index value source. The receiver is in communication with the transmitter. The image processing component is in communication with the receiver. The image processing component includes a lookup table. The image processing component is capable of generating a pixel value based at least in part on an index value and a lookup table. The pixel value has a bit-width greater than the index value. In an embodiment, the receiver is in wireless communication with the transmitter.

  • Publication number: 20060109958
    Abstract: A method and system of aligning an x-ray detector and x-ray tube for data acquisition are presented. The x-ray detector and x-ray tube are equipped with transmitters and receivers designed to provide feedback relating to the orientation, spacing, and general position thereof. In this regard, a user can effectively and efficiently position the x-ray tube and x-ray detector relative to one another for data acquisition.

  • Publication number: 20060083351
    Abstract: A method for x-ray scatter correction during simultaneous bi-plane imaging using digital image processing. The basic concept includes correcting the image from each plane by combining it with an image of the scatter generated from the exposures of the opposite plane in such a way that the scatter effects are removed. The correction image is formed by sampling images from the detector with only the x-ray exposure of the scatter producing plane being active. These sampled images of scatter are processed to form the scatter correction image. The scatter correction image is stored in an image memory so that it is available for combination with subsequent x-ray images to remove scatter distortion.

  • Publication number: 20050207534
    Abstract: Systems and methods are provided for managing power consumption of a medical imaging detector by the use of triggering signals, environmental condition data, and/or determination of a variable time interval triggering event that is unique for each power consumption state. Systems and methods are provided for managing power and temperature of a device, after receiving a request for a function to be performed by the device determining an “on” trigger component, an “off” trigger component, associated circuits for performing the received function, providing power to the associated circuits upon the occurrence of the “on” trigger component, and removing power to the associated circuits upon the occurrence of the “off” trigger component. Further, an instruction is described for determining and displaying a variable time interval that is indicative of a time to change from one state to a desired state.
