  • Patent number: 10111638
    Abstract: A method and apparatus is provided to perform material decomposition based on spectral computed tomography (CT) projection data generated using registered reconstructed images. Registration is performed in the image domain, whereas material decomposition is performed in the sinogram domain. In the sinogram domain, material decomposition can include beam-hardening corrections. For at least two energy components, CT images are reconstructed, and registration is performed among the CT images. In certain implementations, the registered images are forward projected, and material decomposition is based on the resultant forward projections. In other implementations, motion images are generated from differences between the reconstructed CT images pre- and post-registration. The projection data is then corrected using forward projections of the motion images, and material decomposition is performed using the motion-corrected projection data.

The method includes acquiring a first set of data by under-sampling a first portion of a k-space at a first rate, and a second set of data by under-sampling a second portion of the k-space at a second rate. The method generates a first intermediate image and a second intermediate image based on the acquired first set of data and the acquired second set of data, respectively, and constructs a difference image including artifacts based on the generated first intermediate image and second intermediate image. The method includes reconstructing a final image, by selectively combining the first intermediate image with the second intermediate image, wherein the combining is based on identifying, for each artifact included in the difference image, one of the first intermediate image and the second intermediate image as being a source of the artifact.
