Abstract: A method for positioning sensor units in a detector module for a CT device includes arranging a connecting layer on a positioning substrate. Sensor units and readout units, forming sensor readout arrangements, are positioned relative to the positioning substrate. The sensor units are temporarily connected to the positioning substrate at a fixed position by the connecting layer. Electronics boards are positioned, and conductive connections are produced between the electronics boards and contacts of the readout units, such that sensor boards are obtained. The sensor units are then positioned by the positioning substrate relative to a module carrier and are attached to the module carrier, such that a detector module is obtained.

Abstract: A detector module for an X-ray detector is disclosed, which includes, in a stacked structure, a sensor layer with a sensor surface to which a high voltage can be applied for the detection of X-rays. A coherent protective film is arranged on at least two side surfaces of the stacked structure. An X-ray detector is also disclosed, including a number of corresponding detector modules.
