A collimator (12) for a beam detector, comprises at least two juxtaposed collimator plates (20); and at least one supporting element (13), arranged between at least two juxtaposed collimator plates, for stiffening the collimator. The supporting elements are constructed from a material transparent to X-rays and support the collimator plates laterally. The collimator includes at least two supporting elements, interconnected in such a way that the collimator includes a device including slots between the supporting elements, each one slot being provided for holding a collimator plate. Die Erfindung betrifft einen Kollimator (12) für einen Strahlendetektor (5), aufweisend mehrere nebeneinander angeordnete Kollimatorbleche (20), zwischen denen zur Versteifung des Kollimators (12) jeweils wenigstens ein aus einem röntgentransparenten Material ausgebildetes, die Kollimatorbleche (20) seitlich stützendes Stützeelement (13) angeordnet ist. Die Erfindung betrifft außerdem ein einen derartigen Kollimator (12) aufweisenden Computertomographiegerät (1).
