Figure 1
Charge sharing in pixelated X-ray detectors and photon location recovery. (a) Simulated sparse Gaussian charge clouds generated from weak X-ray scattering. (b) Magnified view of a region of interest from (a), showing an 8 × 8 pixel area. The solid white lines indicate the pixel boundaries. One can see photons that straddle across pixel boundaries. (c) Simulated detector image by binning (b) down to the outlined pixel grid and adding readout noise. Centers of the charge cloud representing the photon locations are indicated by circles. (d) Detector image after setting pixel readouts below a threshold to 0. In total four droplets are identified as indicated by the boundaries drawn in white. Photon positions recovered by the algorithm used in the work by Hruszkewycz et al. (2012  ) are plotted with `+'. The color bar is shared by (c) and (d). The nominal one photon readout is 151 in our simulation. |
