摘要： Methods for energy-sensitive computed tomography systems that use checkerboard filtering. A method of enhancing image analysis of projection data acquired using a detector configured with a checkerboard filter includes disposing in a system a detector to receive a transmitted beam of X-rays traversing through an object, where the system is configured so the detector receives both high- and one of total- and low-energy projection data; receiving the high- and one of total- and low-energy projection data at the detector; and then estimating an effective atomic number of the object and/or processing the projection data so as to mitigate reconstruction artifacts. The present invention has been described in terms of specific embodiment(s), and it is recognized that equivalents, alternatives, and modifications, aside from those expressly stated, are possible and within the scope of the appended claims.

摘要： A technique is provided for the temporal interpolation of a projection data set acquired of a dynamic object, such as a heart. The projection data set is acquired using a slowly rotating gantry and a distributed X-ray source. The projection data may be interpolated at each view position to a selected instant of time, such as relative to a cardiac phase. The resulting interpolated projection data characterize the projection data at each view location at any instant in time. The set of interpolated projection data may then be reconstructed to generate images and/or volume with improved temporal resolution.

摘要： A method, computed tomography (CT) system and computer-readable medium for reconstructing an image volume of an object scanned in helical mode. An embodiment of the method includes determining discrete focal lengths within an imaging plane of the reconstructed field of view comprising the image volume; generating a circular scan sinogram(s) for the discrete focal lengths by interpolating the helical views; selecting within a backprojection operation a circular scan sonogram(s), for one or more image points within the imaging plane, over one or more circular views. The method then includes using the selected circular scan sinogram(s), in the backprojection of the image points point(s) over the circular views view(s) and performing a backprojection for all the image points over all the circular views to generate a reconstructed image of the object.

摘要： 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.

摘要： 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.
