X-ray images are life size. No lens. Just throw the right amount of photons at something and it makes an image on film. Kinda like something we did in first or second grade, where we laid leaves and other items on light sensitive paper, exposed the whole mess to sunlight for a few moments and the result was a shadow of whatever blocked the light, and with leaves they looked like x-ray images.
Actually these shots of my foot and hip are digital, so they must be using some sort of sensor. The technician had several plates, or cassettes, just like they used for film imaging, but she just set them aside while composing and making the next image with another. They aren't connected with cables, so I suspect there is some sort of electronic telepathy going on to transfer the image data. As she was working, composing the next shot, the software was processing the last image. It took about 10 to 15 seconds for each one to get done.
Neat stuff.
