thank you ,the I/I you explain is the old type a bit like a large jam pot
the face or bottom of j/p coved in phosphor the top j/p has 35cm phosphor target , the x rays hit the base phosphor and give off photons which are excelerate to the viewing target two or three round anode are place in the jar to excelerate the photons to the taget,and to focus the photons [ the anode volt are about 25kv] the target face then
has an optical lens fitted and the a television camera.
The device I was looking for look like a large sandwidge bok about 12inches square and 6inches deep, used on cardiac C armes .
I think it may be the same technology as flat screen t/v.
