Hi, I need some information on how to digitalize the X-rays applied to a body. (Replacing the x-ray film, obviously). It is not to make a device, only the theory of operation and some diagrams. I have heard there are to methods: direct and indirect. Via phosphor material or directly to a phototransistors array.There is a lot of info in web but no deep information about the electronics implied. Also, -as a bonus- a comparison between Toshiba, General Electric and Siemens. I'm confident there is someone who works on that field in Piclist. Thank you in advance for the links or books suggested.
