A dedicated X‐ray imaging detector for 200 keV high‐energy X‐ray microtomography was developed. The novelty of the detector is a large‐format camera lens employed for a wide field of view. Several scintillators were evaluated in terms of the degree of efficiency of detection for high‐energy X‐ray photons and the modulation transfer function. For tomographic measurement, a high‐definition CMOS camera was incorporated in the detector to achieve a high spatial resolution while keeping the field of view wide. Rocks with fossil inclusions were imaged to demonstrate the applicability of the detector to high‐energy X‐ray microtomography.
