Digital Radiography — Engineer Field Guide

Top failure modes

1. Detector panel battery aging — wireless panels lose charge faster over 3–4 years.
2. Panel scintillator aging — CsI efficiency drops; rarely catastrophic, measured in lost DQE.
3. Ceiling-tube cable tracks — long-term wear.
4. Tube anode end-of-life — anode bearing noise.
5. Generator arcing — HV tank oil contamination.
