Development of large field of view and high-definition real-time digital radiography system

We have developed a high definition real-time DR system capable of 2000 line scan adopting a high resolution TV camera using a 2' Saticon imaging tube and a 16' high definition x-ray image intensifier. As a result, we obtained the dynamic range of a DR image, namely latitude of x rays, of 79 that is comparable to that of the film-screen system, and a limiting spatial resolution of 2.5 lp/mm for a maximum field-of-view of 16'.
