Abstract:
Method of producing magnetic resonance images, wherein a (n+1) dimensional k space is scanned, comprising an imaging pulse sequence with at least one RF excitation pulse (1) followed by at least one RF refocusing pulse (4), wherein an incomplete complex spin echo signal Sx is measured and digitized in one part of a read-out interval [t0âˆ’Â½ta,t0+Â½ta] by means of a quadrature detector, which has a central part about the center (t=t0) of the spin echo signal Sx in the time interval [t0âˆ’&egr;, t0+&egr;] with (n=0, 1, 2, . . . ) phase encoding gradients (8) before the read-out interval, wherein the digitized, incomplete, complex spin echo signal Sx is completed through adding zeros for the entire read-out interval and the central part is weighted with a function which is substantially anti-symmetrical about the point t=t0 and has an amplitude of Â½ at the point t0 and is subsequently Fourier-transformed for producing a Fourier-transformed signal, and that the Fourier-transformed signal is phase-corrected.
