FAN-BEAM COHERENT-SCATTER COMPUTED TOMOGRAPHY

摘要

A reconstruction of data from CSCT data usually requires a long reconstruction time. According to the present invention, a filtered back-projection of CSCT data, wherein the CSCT data comprises a spectrum acquired by means of an energy resolving detector element is provided, wherein the filtered back-projection is performed along curved lines represented by the wave-vector transfer in the reconstruction volume. Advantageously, a reconstruction time may be reduced, while allowing for a good image quality.
