Abstract:
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.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
