Patent ID: 8111893

Claim:
A method for reconstructing an image of a subject with an x-ray imaging system, the steps comprising: a) acquiring, with the x-ray imaging system, a time series of image data of the subject; b) forming an expanded image frame data set by combining image data associated with a current time frame with image data not associated with the current image frame; c) selecting an estimate image of the subject; d) reconstructing a prior image of the subject from the time series of image data acquired in step a); e) producing a sparsified image of the subject using the prior image and the estimate image; and f) reconstructing an image of the subject corresponding to the current time frame using the sparsified image, the estimate image, and the acquired time series of image data, wherein the image is reconstructed while enforcing consistency between the expanded data set and a forward projection of the image of the subject.
