Abstract
A production method for a sensor unit that includes a scintillator and a support plate on which a stack of collimator sheets is attached. The production method permits precise positioning of the collimator sheets in respect of the scintillator. In the process, individual scintillator strips are initially produced from a plurality of scintillator pixels adjoining one another along one dimension. Respectively one photodiode strip, made of a plurality of photodiodes in turn adjoining one another along one dimension, is attached to each of the individual scintillator strips along a longitudinal side in order to form a sensor strip. In an embodiment, respectively one photodiode is associated with respectively one scintillator pixel for readout purposes. The sensor strips are subsequently individually assembled on an outer side of the support plate facing away from the collimator sheets in order to form the scintillator.
