title: [Experimental determination of weighting functions in magnetic resonance tomography].
abstract: Weighting functions are defined and calculated for the pulse sequences spin-echo and inversion recovery. These weighting functions make possible a qualitative discussion of the term "weighting" in MR imaging. Furthermore, a new method has been developed to determine weighting functions experimentally. A comparison between the results obtained and the theoretical predictions shows a sufficiently good agreement. This method can also be applied with other pulse sequences.
