FIELD: computer tomography.
SUBSTANCE: imaging system includes an energy resolving detector (20) which generates data indicative of detected radiation having at least first and second energies. The system also includes an energy pre-processor (24), a motion calculator (26), and a reconstructor (22). In one embodiment, the apparatus uses a k-edge imaging technique to perform a motion compensated reconstruction of projection data indicative of an object under examination.
EFFECT: enhanced object reconstruction with motion compensation.
