Patent ID: 6883963

Claim:
A method for exchanging a first detector module (m), including K channels (x) from k to j in an X-ray detector in a computed tomograph including a module configuration a with a total of M detector modules and K×M channels, for a second detector module (m′), wherein the first detector module includes an associated correction table (T S(a,m,x) ), for eliminating temperature-dependent signal changes, which is dependent on the respective module configuration of the detector and is recreatable following the exchange of a detector module, comprising: creating, for the first and second detector modules in a detector in a reference computed tomograph including the module configuration b, a respective correction table (T S(b,m,x) , T S(b,m′x) ; ascertaining difference values in the correction tables; and calculating a new correction table (T S(a,m′,x) ), for operating the second detector module (m′) in the computed tomograph including the module configuration a, by transferring the ascertained difference values to the old correction table (T S(a,m,x) ).
