We developed an X-ray imaging detector using single-crystal diamond, which has unique properties like high radiation tolerance and a similar atomic number to human tissue. The system includes an indium plate electrode, a pixelated silver electrode, and a photon-counting ROIC. We successfully imaged a 1 mm-thick lead plate using 100 kV X-rays, motivating further optimization for single-crystal diamond detectors.
