Abstract: Disclosed are embodiments of methods for reconstructing x-ray projection data (e.g., one or more sinograms) acquired using a multi-source, inverse-geometry computed tomography (“IGCT”) scanner. One embodiment of a first method processes an IGCT sinogram by rebinning first in “z” and then in “xy,” with feathering applied during the “xy” rebinning. This produces an equivalent of a multi-axial 3rd generation sinogram, which may be further processed using a parallel derivative and/or Hilbert transform. A TOM-window (with feathering) technique and a combined backprojection technique may also be applied to produce a reconstructed volume. An embodiment of a second method processes an IGCT sinogram using a parallel derivative and/or redundancy weighting. The second method may also use signum weighting, TOM-windowing (with feathering), backprojection, and a Hilbert Inversion to produce another reconstructed volume.
Abstract translation: 公开了用于重建使用多源反相几何计算机断层摄影（“IGCT”）扫描仪获取的x射线投影数据（例如，一个或多个正弦图）的方法的实施例。 第一种方法的一个实施例通过在“z”中首先重新组合，然后在“xy”中重新组合来处理IGCT正弦图，在“xy”重组期间应用羽化。 这产生等效的多轴向第三代正弦图，其可以使用平行导数和/或希尔伯特变换进一步处理。 TOM窗口（具有羽化）技术和组合的反投影技术也可以应用于产生重建体积。 第二种方法的实施例使用并行导数和/或冗余加权处理IGCT正弦图。 第二种方法还可以使用信号加权，TOM窗口（具有羽化），反投影和希尔伯特反演来产生另一个重建的体积。

Abstract: Approaches are described for generating an initial reconstruction of CT data acquired using a wide-cone system. The initial reconstruction may be processed (such as via a non-linear operation) to correct frequency omissions and/or errors in the reconstruction. Corrected frequency information may then be added to the reconstruction to improve the reconstructed image.
