摘要： A method for Computed Tomography (CT) imaging is provided. The method comprises rotating a gantry at a substantially slow rotation speed about a volume of interest. The gantry comprises a combination of X-ray source points. The X-ray source points comprise one or more discrete emission points and an arc of discrete or continuous X-ray source points. The method then comprises obtaining projection data from the combination of X-ray source points and performing a suitable reconstruction based on the projection data obtained from the combination of X-ray source points, to generate one or more reconstructed images.

摘要： A method and computer-readable medium for reconstructing an image volume of an object scanned in helical mode is provided. The method and computer-readable medium include obtaining one or more helical views corresponding to an image volume of an object and determining a plurality of discretized focal lengths within an imaging plane of the reconstructed field of view comprising the image volume. The method then comprises generating a plurality of circular scan sinograms for the plurality of discretized focal lengths. The plurality of circular scan sinograms are generated by interpolating the helical views. The method then comprises selecting one or more circular scan sinograms from the plurality of circular scan sinograms, based on the plurality of discretized focal lengths, wherein the selection is performed within a backprojection operation, for one or more image points within the imaging plane, over one or more circular views. The method then comprises using one or more of the selected circular scan sinograms, in the backprojection of one or more of the image points over one or more of the circular views. The method finally comprises performing a backprojection for all the image points over all the circular views to generate a reconstructed image of the object.
