SUPER-RESOLUTION MAGNETIC RESONANCE IMAGING

摘要

A method for obtaining a magnetic resonance image of an object with a given pulse sequence, wherein the method comprises applying a first modulation of the longitudinal magnetization for producing a periodic spatial modulation of the longitudinal magnetization with a wavelength of a pixel width, performing the pulse sequence with a given field of view to acquire a first image of the object, applying a second modulation of the longitudinal magnetization that is spatially shifted by a part of the wavelength, performing the pulse sequence with a field of view shifted by a part of a pixel width to acquire a second image of the object, merging the first image and the second image in the image domain in an interleaved fashion pixel by pixel, and deconvolving the merged image using the modulation function.
