In accordance with a questionnaire survey of diagnostic X-ray equipment enforced in 2005, this report was focused mainly on a photography device. The paper questionnaire was mailed to 667 institutions, and the collection rate was 20.4%. Introductions of digital photographic devices are progressing and flat panel detectors (FPD) are spreading in addition to computed radiography (CR). Examination revealed that the spread rate of FPD was 14.4%. The inverter-type device occupied 73.4% in group of high-voltage-generation devices. We reason that the spread rate indicates changeover to an inverter-type device. Changes in photography equipment and photography devices will bring change in photographic technology. Such investigation will be necessary in the future.
