DERIVING TIME-AVERAGED MOMENTS

摘要

The invention relates to a method of deriving time-averaged moments of a convolution profile from dynamic input and arrival profiles. A convolutive relation exists between the arrival profile and the input profile. According to the invention the time-averaged moment of the convolution profile is calculated from time-averaged moments of the dynamic input and arrival profiles. The method is used notably for the study of perfusion effects by means of magnetic resonance imaging.
