Abstract
A system and method of 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 attenuated by the object, a data acquisition system (DAS) operably connected to the detector, and a computer operably connected to the DAS. The computer is programmed to obtain CT scan data with two or more incident energy spectra, decompose the obtained CT scan data into projection CT data of two or more basis materials, reconstruct linearly weighted projections of the two or more basis materials, determine an optimized energy for the two or more basis materials within a region-of-interest (ROI), and form a monochromatic image of the projection CT data at the optimized energy using the two or more basis material projections.
