IMG = PIFFT(KSP)

The input KSP is assumed to be a rectangular matrix with the number of rows equaling the number of phase encodes (lines) of the image's k-space. The first rows of the matrix should be the highest frequency phase encodes acquired so that the center of k-space is near the bottom of the matrix. The image is reconstructed for the next highest power of 2 greater than the number of phase encodes in the partial k-space data set.
