Abstract:
Method for evaluating measured periodic or quasiperiodic signals of medical sensor systems, comprising the steps of:digitizing the measured signals with a specific first sampling frequency; normalizing the periods of the measured signals to a predetermined period length; using a database in which previously measured signals are stored after digitization with specific second sampling frequencies and in which medical findings are assigned to the stored signals; if the first and second sampling frequencies are not identical, converting the measured signal of the signals stored in the database so as to have the same sampling frequencies; comparing at least a section of the digitized measured signal with a corresponding section of the signals stored in the database; determining an accumulation of correspondences between stored signals and the measured signals and determining a correspondence accumulation of medical findings assigned to said stored signals; and deriving a probability for the presence of a specific medical finding with reference to the measured signal from the degree of accumulation.
