Abstract

A method for generating an image using nuclear magnetic resonance signals, which substantially eliminates the presence of so-called "N/2 ghosts," includes the steps of dividing a measurement matrix into a first sub-matrix containing the even-numbered rows of the measurement matrix and into a second sub-matrix having the odd-numbered rows of the measurement matrix, setting the entries in the remaining rows of the sub-matrices to zero, subjecting both sub-matrices to a Fourier transformation at least in the column direction, thereby generating respective intermediate image matrices, multiplying one of the intermediate image matrices by a factor which is calculated from the edge rows of the intermediate image matrices, and adding the intermediate image matrices after the multiplication.
