Abstract
An image, such as a radiographic diagnostic image, is increased in brightness by an image intensifer (B). A multiport image distributor (C) receives the image from an convergent lens (34) and distributes it among a plurality of outlet ports (38, 42, 44, 46, 48). A plurality of cameras (D) or other image receiving processing devices are connected with the outlet ports. The image distributor includes a plurality of modules (50A, 50B, 50C), each of which moves a beam splitter (60) into and out of a beam splitting position. In the beam splitting position, each beam splitter divides the received image between two of the output ports. The four modules in the preferred embodiment enable the image to be distributed among up to five output ports.
