  • Publication number: 20050190878
    Abstract: A technique is provided for imaging a field of view using an X-ray source comprising two or more emission points. Each emission point is configured to emit a fan of radiation encompassing less than the entire field of view. The emission points are activated individually and rotate about the field of view, allowing respective streams of radiation to be emitted at various view angles about the field of view. The emission points, which may correspond to different radial regions of the field of view, may be differentially activated to emphasize a region of interest within the field of view. The multiple emission points may be extrapolated along the longitudinal axis in duplicate or offset configurations.

  • Publication number: 20050169420
    Abstract: A method for computing volumetric perfusion using a computed tomography imaging (CT) system is presented. The method includes irradiating a spatially dynamic object within a field of view of the computed tomography imaging system for requisite view angle positions of the gantry. Furthermore, the method includes operating the computed tomography imaging system in a continuous data acquisition mode to acquire projection data representative of the spatially dynamic object. In addition, the method includes processing the projection data to generate time-resolved projection data. Reconstructions are generated using the time-resolved projection data. Additionally, the method includes computing the volumetric perfusion in the spatially dynamic object using the reconstructed data. Computer-readable medium that afford functionality of the type defined by this method is also contemplated in conjunction with the present technique.

  • Publication number: 20050111610
    Abstract: Configurations for stationary imaging systems are provided. The configurations may include combinations of various types of distributed sources of X-ray radiation, which generally include addressable emitter elements which may be triggered for emission in desired sequences and combinations. The sources may be ring-like, partial ring-like, or line-like (typically along a Z-axis), and so forth. Combinations of these are envisaged. Corresponding detectors may also be full ring detectors or partial ring detectors associated with the sources to provide sufficient coverage of imaging volumes and to provide the desired mathematical completeness of the collected data.

  • Publication number: 20050100127
    Abstract: A method for imaging an object that includes utilizing a computed tomography imaging apparatus having a distributed x-ray source to acquire samples of projection data of an object in angular and temporal space utilizing a predetermined sampling lattice. Acquired projection data is filtered utilizing a two-dimensional linear filter to produce filtered data, and the filtered data is then backprojected to obtain a reconstructed image of the object.

  • Publication number: 20050094771
    Abstract: The present invention provides a method for determining a geometry of a scanning volumetric computed tomographic (CT) system having a rotation axis, a rotational plane, an x-ray source and a detector. The method includes scanning a phantom having a series of spatially separated discrete markers with the scanning volumetric computed tomographic system, wherein the markers are configured on a supporting structure of the phantom so as to permit separate identification of each marker in a collection of projection images. The method further includes locating images of the markers in each projection, using the located marker images to assign marker locations to tracks, and using the assigned tracks, determining a relative alignment between the detector, the source, and the rotation axis of the scanning volumetric computed tomographic system.

  • Publication number: 20050031075
    Abstract: A system and method for ascertaining the identity of an object within an enclosed article. The system includes an acquisition subsystem utilizing a stationary radiation source and detector, a reconstruction subsystem, a computer-aided detection (CAD) subsystem, and a 2D/3D visualization subsystem. The detector may be an energy discriminating detector. The acquisition subsystem communicates view data to the reconstruction subsystem, which reconstructs it into image data and communicates it to the CAD subsystem. The CAD subsystem analyzes the image data to ascertain whether it contains any area of interest. Any such area of interest data is sent to the reconstruction subsystem for further reconstruction, using more rigorous algorithms and further analyzed by the CAD subsystem. Other information, such as risk variables or trace chemical detection information may be communicated to the CAD subsystem to be included in its analysis.
