A method for the analysis of a measurement signal in particular a medical image detector on the extreme deviations

摘要

A method for the analysis of individual signal values (s (k)) existing measuring signal (s) to extraordinary deviations, in particular a measuring signal (s) of a medical image detector (8), wherein the measuring signal (s) with a plurality of channels (k) and detector (8) has been detected and each channel (k) a respective signal value (s (k)) is associated, wherein in a first step, the measurement signal (s) is subjected to a preprocessing, in a second step the preprocessed signal (s^K) for determining a filtered signal (tp) is subjected to a filtering, in a third step the measurement signal (s) and the filter signal (tp) are compared with each other, whereby by means of the preprocessing of a signal group (sg (m)) in the measurement signal (s) is determined, which has an extraordinary deviation, and in the region of the signal group (sg (m)) the measurement signal (s) is corrected, in such a way,that an artifact (af) in the filter signal (tp (s^K)) in particular in the edge region of adjacent signal groups is avoided.
