Method for determining at least one diagnostic piece of information from signal patterns of medical sensor systems
First Claim
1. 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.

Abstract
A method for evaluating measured periodic or quasiperiodic signals of medical sensor systems. The method comprises 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. Also, 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 the stores signals and deriving a probability of the presence of a specific medical finding with reference to the measured signal from the degree of accumulation.
