The X-ray-based cancer imaging simulation toolkit (XCIST) project was supported by the National Cancer Institute of the National Institutes of Health under Award Number U01CA231860 (ITCR grant). Its content is solely the responsibility of the authors and does not necessarily represent the official views of the National Institutes of Health.
The XCIST toolkit includes material files and software developed by Members of the Geant4 Collaboration (http://cern.ch/geant4). Specifically, it builds on the X-ray attenuation cross-sections produced by Geant4.
The XCIST toolkit includes spectra produced using XSPECT (https://websites.umich.edu/~ners580/ners-bioe_580/labs/_doc/XSPECT_v3-5c.pdf).
