Abstract: An imaging system (500) includes a data acquisition system (515) configured to produce projection data and at least one memory device with reconstruction algorithms (518) and at least one blending algorithm (524). The imaging system further includes a reconstructor (516) configured to reconstruct the projection data with the reconstruction algorithms and generate at least first spectral volumetric image data corresponding to a first basis material content and second spectral volumetric image data corresponding to a second basis material content, and blend the first spectral volumetric image data and the second spectral volumetric image data with the at least one blending algorithm to produce blended volumetric image data.

Abstract: A computing system (118) includes a computer readable storage medium (122) with computer executable instructions (124), including a biophysical simulator (126), and a reference location (128), and a processor (120) configured to the biophysical simulator and simulate a reference FFR value at a predetermined location along a segmented coronary vessel indicated by the reference location. A computer readable storage medium encoded with computer readable instructions, which, when executed by a processor of a computing system, causes the processor to simulate a reference FFR value at a predetermined location along a segmented coronary vessel indicated by a predetermined reference location. A method including simulating a reference FFR value at a predetermined location along a segmented coronary vessel indicated by a predetermined reference location.
