摘要：
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.
