ABSTRACT:
A radiation diaphragm has an arrangement for introducing at least one radiation filter into the beam path of a radiation bundle emanating from a radiation transmitter. A light transmitter is provided for creating a light beam which optically represents the area of the radiation beam. A filter identifier is provided in the diaphragm housing for changing the color of the light beam dependent on whether a radiation filter is located in the radiation beam path. Based on the color of the light beam incident on the examination subject, it is possible to determine whether a radiation filter is located in the radiation beam path, and if so, which filter.
