Abstract: A method for controlling a gas turbine, wherein measurement signal values are measured at different times, namely at least a first time and a second time, wherein the first time lies before the second time and wherein attenuated signal values are generated from the measurement signal values by smoothing the measured measurement signal values by means of a attenuation factor, wherein a different attenuation factor is used depending on the difference of the measurement signal value at the second time and the attenuated signal value at the first time.

Abstract: To simplify the reconstruction of structural data of an object (7) examined using a tomography device (1), it is proposed to implement a radiation source (4) in such a way that radiation bundles (6) with parallel beam geometry are produced.
