Abstract

A method has been developed to reduce a magnetic resonance image artifact arising from the Fourier transformation of data truncated in the phase-encoding direction. The discontinuity is eliminated between the phase of the complex data sample associated with the maximum negative phase-encoding gradient and the phase of the maximum positive gradient sample. Images retain sharper edges than if low-pass filtering is employed. The method is demonstrated on clinical images, then an explanation of the method is presented.
