Abstract

In an NMR tomography method, the nuclear spins are caused by a pulse sequence to supply in one pass a number of successive induction signals, whereupon the induction signals corresponding to each other as regards their succession in time are processed by calculation to form a plurality of image signal sets corresponding to a sequence of section images which differ from each other by the intensity of the induction signals varying according to the relaxation time T.sub.1 or T.sub.2. Thereafter one establishes for each image point associated with a single volume element of the body cross-section a function describing the variation in time of the image signals associated with the respective image points in the different image signal sets, and generates a further image signal set by extrapolating the functions thus established to a point of time situated before the pre-determined measuring moment defined by the start of a pulse sequence following a first output pulse, and uses the image signal set thus obtained for producing a section image.
