ABSTRACT:
In a pulse sequence according to the turbo-spin echo method, only a part of the raw data matrix (MR) that lies asymmetrically relative to a zero line and that contains this zero line is filled with samples, whereby phase-coding gradients (GPS) are switched such that the echo signals that are only slightly dephased by the phase-coding gradient are acquired closely following a radio-frequency excitation pulse (RF1). These signals are thus entered into the central lines of the raw data matrix (MR) which are the ruling factor in determining the weighting of the reconstructed image.
