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 digital X-ray detector includes a width of a data line or a gate line extending across a dummy pixel area is smaller than a width of the data line or the gate line extending across an active area, a width of a dummy gate line or a dummy data line extending across the dummy pixel area is smaller than a width of the gate line or the data line extending across the active area, so that static electricity generated during a manufacturing process does not randomly flow into the active area, but rather flows into the dummy pixel area having the lowest capacitance, and the static electricity may be guided not to the active area but to the dummy gate line or dummy data line in the dummy pixel area, thereby minimizing line defects or block luminance deviation defects caused by the static electricity generated during the manufacturing process.
