NIPPON-KOKEN's Indirect X-ray Camera

Direct shooting of X-ray required huge equipment and darkroom. To solve this problem, a method of fluorescent image photographing by an X-ray indirect imaging apparatus was established.

In 1942, the Ministry of Health and Welfare of Japan established a fluorescent screen size of 35 cm x 35 cm as a standard. The screen size of the X-ray camera film was 24 mm x 24 mm. It was possible to take 50 pictures with one film magazine.
