Abstract: A multiple frames imaging system is disclosed with capability of differential x-ray exposure of different input areas of an image intensifier or other x-ray detector. Collimators are provided to control the amount of radiation in various regions of the image and image processing is provided to provide the display of images of different qualities. Motion methods are provided to move the collimators to produce optimal image frames.
