Abstract: A method is provided including acquiring imaging data of an object to be imaged from a computed tomography (CT) detector. The method also includes reconstructing the acquired imaging data into an initial reconstruction image, and performing material characterization of an image volume of the initial reconstruction image to provide a re-mapped image volume. Further, the method includes performing forward projection on the re-mapped image volume to provide forward projection data, and providing an error projection based on the forward projection data. Also, the method includes filtering at least one of the initial reconstruction image, the re-mapped image volume, the forward projection data, or the error projection. The method also includes using the error projection to update the initial reconstruction image to provide an updated reconstruction image.

Abstract: Various methods and systems for generating a computed tomography image in real-time are provided. In one embodiment, a method for imaging comprises acquiring x-ray projection data; calibrating the x-ray projection data; generating at least two basis image volumes by reconstructing the calibrated x-ray projection data, each of the at least two basis image volumes including different centerviews and a temporal width corresponding to an x-ray source rotation between 180 degrees and 360 degrees; and generating a final image volume by Fourier blending the at least two basis image volumes based on a selected temporal window width. In this way, a user may scroll between Fourier-blended images of varying durations of temporal window in real-time to select an optimal image for review without a reconstruction of calibrated x-ray projection data for each image.

Abstract: Systems and methods for iterative multi-material correction are provided. A system includes an imager that acquires projection data of an object. A reconstructor reconstructs the acquired projection data into a reconstructed image, utilizes the reconstructed image to perform a multi-material correction on the acquired projection data to generate a multi-material corrected reconstructed image, and utilizes the multi-material corrected reconstructed image to perform one or more iterations of the multi-material correction on the projection data to generate an iteratively corrected multi-material corrected image.

Abstract: Methods and systems are provided for boosting the contrast levels in an image reconstructed from projection data acquired at a single energy. In one embodiment, a method comprises modifying projection data corresponding to a material based on an absorption behavior of the material at a selected energy, wherein the projection data is acquired at an energy higher than the selected energy. In this way, contrast levels may be enhanced in an image reconstructed from projection data acquired at a typical single energy as though the image were reconstructed from projection data acquired at a lower energy.
