摘要

A process for the evaluation of the intensity values of data of a nuclear magnetic resonance, wherein at least a relaxation signal of a sample is determined whose changes with a time constant t₂* are characterized and, furthermore, the intensity values in at least two different dependencies of an echo time t_E be separated, characterized by the,that a standard deviation σ (δt₂*) determined as well as a quotient σ (δt₂*)/T₂* is formed, the quotient as a measure of an activity is detected, and, furthermore, a standard deviation σ (g) of a noise signal g is formed, wherein σ (δt₂*) and σ (g) are determined by subsequent steps:(i) the recorded data are in an at least two-dimensional field is detected, wherein a field axis (dte) echo times t_E and a different field axis (dtr) repetitions of excitations at a time interval of t_R reproduces;(ii) by means of adjusting dtr averaged signals to an exponential decay in a function of dte and determining s₀ and t₂*, wherein as a start intensity represents;(iii) calculation of σ (δt₂*) and..
