Sensor board of a detector module and process for its preparation

The invention relates to a sensor board (1, 41, 71, 131, 181) of a detector module (46, 127) comprising, in a stacked structure (13, 31, 53, 75, 145, 186) at least a reading unit (15, 33, 55, 83, 143, 187) and one (in the stacking direction 16, 34, 56, 81, 146, 191) spaced apart from the read-out unit (15, 33, 55, 83, 143, arranged 187) sensor layer (9, 27, 47 , 77, 137, 183), wherein the sensor layer (9, 27, 47, 77, 137, 183) in a longitudinal direction (42, 99, 133, 177) transversely to the stacking direction (16, 34, 56, 81, 146, 191) in at least one edge region (97, 115, 195) has a projection (101, 107) opposite to the read-out unit (15, 33, 55, 83, 143, 187), wherein the (by the spacing between the sensor layer 9, 27 , 47, 77, 137, 183) and the read-out unit (15, 33, 55, 83, 143, 187) existing space (19, 37, 57, 85, 149, 203) in such a way with a cured filler (116, 167, 201) is filled, that at least one edge region (67, 102, 166, 207) of the sensor layer (9, 27, 47, 77, 137, 183) is free (of the filling material 116, 167, 201). Furthermore, the invention relates to a method for producing a corresponding sensor boards (1, 41, 71, 131, 181, as well as a detector module (46, 127) for an X-ray detector having a plurality of adjacent to each other on a module carrier arranged sensor boards (1, 41, 71, 131, 181).
