METHOD AND APPARATUS FOR BASIS MATERIAL DECOMPOSITION WITH K-EDGE MATERIALS |
摘要 |
A diagnostic imaging system includes a high frequency electromagnetic energy source that emits a beam of high frequency electromagnetic energy toward an object to be imaged, a detector that receives high frequency electromagnetic energy emitted by the high frequency electromagnetic energy source, and a data acquisition system (DAS) operably connected to the detector. A computer is operably connected to the DAS and is programmed to generate corresponding sets of projection values for three or more energy spectra through employment of attenuation coefficients of three or more basis materials to simulate responses of the diagnostic imaging system to a plurality of lengths of the three or more basis materials wherein the three or more basis materials comprise two or more non K-edge basis materials and one or more K-edge basis materials.
