ITERATIVE RECONSTRUCTION FOR SPECTRAL CT BASED UPON COMBINED DATA OF FULL VIEWS OF INTENSITY DATA AND SPARSE VIEWS OF SPECTRAL DATA

摘要

Full views of the intensity data and the sparse views of the spectral data are obtained so as to combine the two sets of the acquired data. An image is reconstructed using an iterative reconstruction algorithm to minimize a predetermined cost function based upon the combined two sets of full views of the intensity data and the sparse views of the spectral data.
