Abstract
During measurement cycles for generating and sampling FID signals in NMR imaging devices, a 180.degree. pulse and subsequently a 90.degree. excitation pulse are added to the pulse sequence. The 180.degree. pulse produces an additional echo signal. During (the maximum of) the echo signal, the 90.degree. pulse is generated. The waiting period occurring before the beginning of a next measurement cycle can thus be substantially reduced without giving rise to a significant signal loss in the echo signals to be generated during said cycle. In addition to a reduction of the measurement time, NMR images with different contrasts (other intensity distribution) can be provided.
