X-ray imaging is indispensable in medical diagnostics and material characterization. To generate an image, a detector converts X-rays that pass through the object into electrical signals. Higher detector sensitivity enables lower radiation doses, which is particularly important in medical applications.

Currently used X-ray detectors consist of inorganic compounds of elements with medium to high atomic numbers. In recent years, inorganic perovskite compounds have also been tested as X-ray detectors with very good results.
