CPC G01R 33/5616 (2013.01) [G01R 33/4824 (2013.01); G01R 33/5611 (2013.01)] | 11 Claims |
1. An Echo-Planar-Imaging (EPI) magnetic resonance imaging (MRI) method combined with a variable-density undersampling scheme, comprising:
generating a radio frequency (RF) pulse;
applying a switched frequency-encoding read out gradient in a variable time interval; and
applying simultaneously an intermittently blipped low-magnitude phase-encoding gradient with a variable value of an integral of the intermittently blipped low-magnitude phase-encoding gradient, such that k-space is at least partially undersampled,
wherein a time interval of the switched frequency-encoding read out gradient is varied depending on a value of the integral of the intermittently blipped low-magnitude phase-encoding gradient such that a ratio between (i) the variable time interval of the switched frequency-encoding read out gradient, and (ii) the value of the integral of the corresponding intermittently blipped low-magnitude phase-encoding gradient is maintained above or at a predetermined value, and
wherein the predetermined value is based upon a predetermined criteria of image quality.
