摘要:
Methods and systems are provided for motion compensation in computed tomography imaging. In one embodiment, a method comprises reconstructing at least two images from projection data, calculating a motion metric based on the at least two images, selecting a view-weighting function based on the motion metric, and generating a display from the projection data based on the selected view-weighting function. In this way, an image can be reconstructed with the selected view-weighting function which down-weights slices in the image containing motion artifacts. As a result, the image quality of the reconstructed image may be improved with computational efficiency.
