In pinhole-assisted point-projection x-ray radiography (or "backlighting"), pinholes are placed between the sample of interest and an x-ray source (or "backlighter") to effectively limit the source size and hence improve the spatial resolution of the system. Pinholes are generally placed close to such ,x-ray backlighters to increase the field-of- view, leading to possible vaporization and pinhole closure due to x-ray driven ablation, thereby potentially limiting the usefulness of this method. An experimental ,study and
