Abstract

Abstract Translated from German Die Erfindung betrifft ein Verfahren zur Bestimmung der räumlichen und der spektralen Vertelung der Kernmagnetisierung in einem Untersuchungsbereich. Dabei wird im Anschluß an einen Hochfrequenzanregungsimpuls ein periodisch seine Polarität änderndes magnetisches Gradientenfeld eingeschaltet. Das Auflösungsvermögen wird dabei dadurch erhöht, daß auch während der Zeiträume, während der sich der Gradient dieses Feldes ändert, Abtastwerte erfaßt und einer Fourier-Transformation unterzogen werden. The invention relates to a method for determining the spatial and spectral interconnection of the nuclear magnetization in an examination area. Following a high-frequency excitation pulse, a periodically changing magnetic gradient field is switched on. The resolving power is increased in that sampling values are acquired and subjected to a Fourier transformation even during the periods during which the gradient of this field changes.
