Abstract: A method of limiting a X-ray beam, for example in connection with an extraoral radiographic apparatus, includes moving at least two blades of a blade limiting device through one actuator only, so as to produce a X-ray beam having the desired shape, wherein the actuator moves the at least two blades at the same time, in a direct way and in the same direction, even in the event of inversion of the direction of movement of the blades.
