Abstract

Computer-implemented methods for monitoring the functional state of a system for the computer-tomographic examination of workpieces by carrying out one or more computer-tomographic measurements on the workpiece. The measurements each result here in at least one measured value for at least one measurement variable. The method for monitoring the functional state selects measured values for at least one measurement variable from at least two measurements on one or more workpieces. At least one degree of variation for the selected measured values of the at least one measurement variable as well as at least one reference degree of variation for measured values of the at least one measurement variable is determined. The functional state of the system is determined by comparing the at least one determined degree of variation with the at least one reference degree of variation for the at least one measurement variable.
