Abstract

The invention relates to a method for determining and displaying medical informations, in which rough measurement data collected with the aid of different medical measuring methods in at least one measurement interval on the same test subject are stored and in which evaluation data are extracted from the rough measurement data. Further for generating medical informations for at least two selected measuring methods from among the different medical methods, the evaluation data extracted from the in each case associated rough measurement data of a measurement interval are interlinked and for the at least one measurement interval the linked evaluation data are processed as medical informations for outputting on a graphic output device. The invention also relates to an apparatus for performing this method.
