Abstract
A new method is presented for reducing artifact caused by translational motion along phase-encoded direction in magnetic resonance imaging (MRI). The method using the wavelet analysis of magnetic resonance signals has advantages beyond earlier methods: (1) a standard spin-warp imaging sequence is used to postprocess magnetic resonance signals; (2) ghost artifacts can be reduced without blurring of the image; and (3) it is not necessary to know a priori information on the patient. The availability of the method is illustrated by a computer simulation and analysis of magnetic resonance signals obtained from a real MRI system.
