Abstract: A method is for exchanging a first detector module (m), in an X-ray detector in a computed tomograph having a module configuration a, for a second detector module (m?). The first detector module has an associated correction table (TS(a,m,x)) for eliminating temperature-dependent signal changes, which is dependent on the respective module configuration of the detector and which is recreatable following the exchange of a detector module. For the first and second detector modules (m, m?) in a detector in a reference computed tomograph having the module configuration b, a respective correction table (TS(b,m,x), TS(b,m?x) is created. Differences, preferably only in the area of the channels of the detector module which is to be exchanged, are ascertained. Finally, the new correction table (TS(a,m?,x)) for operating the second detector module (m?) in the computed tomograph having the module configuration a is calculated by transferring the ascertained difference values to the old correction table (TS(a,m,x)).

Abstract: A method is for exchanging a first detector module (m), in an X-ray detector in a computed tomograph having a module configuration a, for a second detector module (m′). The first detector module has an associated correction table (TS(a,m,x)) for eliminating temperature-dependent signal changes, which is dependent on the respective module configuration of the detector and which is recreatable following the exchange of a detector module. For the first and second detector modules (m, m′) in a detector in a reference computed tomograph having the module configuration b, a respective correction table (TS(b,m,x), TS(b,m′x) is created. Differences, preferably only in the area of the channels of the detector module which is to be exchanged, are ascertained.
