1. A collimator blade aligning device for aligning mutually facing absorption surfaces of two neighboring collimator blades of a radiation collimator in accordance with a given blade spacing during the production thereof, comprising:
an aligning section, of rod type design, positionable parallel to a longitudinal axis in a positioning position at a given distance along at least one absorption surface and rotatable into an aligning position to align the collimator blade and which has, with reference to a first direction running perpendicular to its longitudinal axis, a first thickness assigned to the aligning position and substantially equal to the given blade spacing, wherein the aligning section includes a second thickness assigned to the positioning position with reference to a second direction running perpendicular to the longitudinal axis and transverse to the first direction and smaller than the blade spacing.
