Figure 9.

Comparison of MANTIS-generated PRFs with PRFs from the analytical model after the 2D fit. All PRFs have been generated with a CsI thickness of 150 μm and an x-ray energy of 25 keV. The incident x-ray beam is modeled in MANTIS as an infinitesimal pencil beam. The incidence angle of the x-ray beam is indicated in the leftmost column, followed by the corresponding MANTIS-generated PRFs, analytical model PRFs, FOMs from the comparison between the MANTIS and analytical PRFs, and, finally, the FOM from the comparison between MANTIS and 2D symmetric Gaussian fits to the normal incidence MANTIS PRF. All PRFs are 0.315×0.315 mm² with 9 μm pixels. Contours are shown for levels of 0.01, 0.05, and 0.1 times the maximum of the PRF.
