Abstract
Considering a rectangular panel of pixels arranged in a grid, we introduce a taxonomy of damages based on spatial arrangements of dysfunctional pixels. We detect these different types of damage in experimental data obtained from a detector from an X-ray machine used for additive layer manufacturing object visualisation. We model the spatial distribution of dysfunctional pixels using point pattern analysis including
intensity estimation and checking for CSR. As a practical application, we propose a protocol for performance monitoring for detector panels.
