ABSTRACT:
For a purpose of improving homogeneity of an image obtained in a self-calibration by a parallel imaging method generally referred to as SENSE (SENSitivity Encoding), sensitivity factors Sn(p) are calculated using an additive image Ab=Σ|Cn| of complex images Cnobtained by conducting a calibration scan of an entire FOV for phased array coils Coil_n (n=1–N, N≧2) (Steps V2, V3). Moreover, sensitivity maps Snare generated by conducting curve fitting by the method of least squares weighted by the square of a pixel value Ab(p) of the absolute value additive image Ab(Step V4).
