Patent ID: 6891372

Claim:
An echo-planar imaging method in which high-frequency pulses are emitted; at least one magnetic gradient field is applied in order to select slice or volume areas in which nuclear magnetic resonances are excited and ascertained as measuring signals whereby, through the magnetic gradient field, several slice or volume areas are consecutively selected and the appertaining measuring signals are detected, and whereby, following the detection of the measuring signals for various slice or volume areas, slice or volume images are formed of the individual slice or volume areas, and a high-resolution reference image (REF<hi-res>) is made, in that additional images having a lower resolution (KEY<low-res>) are made and in that the resolution of the additional images is improved by being linked to the reference image (REF<hi-res>); and keyhole images are reconstructed by means of a phase correction in order to generate completely resolved images.
