A detector unit for detecting X rays passed through a collimator having a plurality of collimator single plates, includes a substrate attached to a collimator support for supporting the collimator, a photodetecting device array including photodetecting devices mounted on the substrate, a scintillator block arranged corresponding to the photodetecting device array and provided on the photodetecting device array to convert the X rays into light, and an engaging component having an engaging portion provided on the collimator single plate side of the substrate, and engaged with the collimator single plate to regulate a position of the photodetecting device array or the scintillator block in a channel direction with respect to the collimator single plate.

Detector unit, X-ray computer tomographic photographing device, X-ray detector, and X-ray detector manufacturing method

A collimator for a scintillator, having a number of through holes formed side by side, each for guiding and passing radiation from one end thereof to an other end and focusing the radiation at a predetermined position, including a frame made of a radiation shielding material, and defining a radiation transparent field of view, and a septa section provided in a lattice form in the field of view so as to define the through holes. The septa section includes a plurality of first partition plates arranged at substantially equal intervals and a plurality of second partition plates crossing the first partition plates in a lattice form. The first and second partition plates are made of a material, preferably tungsten or lead alloy, that sheilds the radiation. A plurality of focused slits are formed in at least either the first or second partition plates with the other partition plates being fitted in the slits.
