  • Publication number: 20150078647
    Abstract: A computer-implemented method of implant detection includes receiving a three-dimensional (3D) image of an anatomy portion of a patient from computed tomography (CT) projections of the patient in an image processing computing system. A cluster of voxels forming an implant candidate is identified on a CT slice of the 3D image and the identified implant candidate is compared with artifacts of implants from an implant database stored in a memory of the computing system. A best-fit implant is selected from the implant database and a graphical image of the best-fit implant is overlaid on the CT slice on a display of the computing system.

  • Patent number: 8948338
    Abstract: An x-ray imaging system for imaging a subject includes an x-ray source configured to project an x-ray radiation toward a portion of the subject and a panel detector positioned opposite the x-ray source relative to the subject and configured to receive x-ray radiation passing through the subject. The panel detector includes a scintillation layer converting x-ray radiation to light rays of a selected spectrum and a plurality of microelectromechanical scanners. Each microelectromechanical scanner includes a photodetector mounted on a corresponding movable platform and configured to detect light in the selected light spectrum. The panel detector includes a scanning control module configured to move each platform in a selected scan pattern.

  • Publication number: 20140314296
    Abstract: A system and a method are disclosed that allow for generation of a model or reconstruction of a model of a subject based upon acquired image data. The image data can be acquired in a substantially mobile system that can be moved relative to a subject to allow for image acquisition from a plurality of orientations relative to the subject. The plurality of orientations can include a first and final orientation and a predetermined path along which an image data collector or detector can move to acquire an appropriate image data set to allow for the model of construction.

  • Publication number: 20140050303
    Abstract: A system and a method for acquiring image data of a subject with an imaging system is provided. The system can include a gantry that completely annularly encompasses at least a portion of the subject, which can be positioned along at an isocenter of the imaging system. The system can include a source and a detector positioned within and movable relative to the gantry on a rotor. The system can include a move control module that sets move data for each of the source, detector and rotor that causes the source, detector and rotor to move in a desired motion profile to acquire image data of a portion of the subject off the isocenter of the imaging system.

  • Publication number: 20120330134
    Abstract: An array emitter including a plurality of emitting portions can be used to individually emit selected energy, such as x-ray radiation, from the emitter ray rather than powering or emitting radiation from all portions of the emitter array. According, providing a plurality of cells within an emitter array, and selectively emitting x-rays from individual cells can allow for selection of which cells to emit x-rays from to acquire selected image data. A process is disclosed for selecting, including automatically, which portions to power to emit energy.

  • Publication number: 20120250822
    Abstract: An X-ray imaging system can include an X-ray source that projects a beam of X-ray radiation and an X-ray detector positioned to receive the beam of X-ray radiation at a location. The X-ray detector can include: (i) a monolithic substrate having a first side and a second side opposite the first side, (ii) a scintillation layer arranged upon the first side and including a first region and a second region, the first region having a first X-ray sensitivity and the second region having a second X-ray sensitivity different than the first X-ray sensitivity, and (iii) a photosensor array arranged upon the second side. The X-ray source and X-ray detector can be configured to adjust the location at which the X-ray detector receives the beam of X-ray radiation such that the location is primarily within the first region or the second region.
