Abstract

Enhanced 3-D reconstruction in NMR diffractive imaging technique which is a new approach to MR angiography, has been investigated. The expression of NMR signals obtained in the NMR diffractive imaging technique is similar to the equation for Fresnel diffraction in light waves or sound waves. Therefore, it is possible to reconstruct images focusing on optional plane in the depth direction using the data scanned two-dimensionally. However blurred image components out of focal-plane superimpose on the focal-plane image and the spatial resolution in the longitudinal direction is degraded. We have developed a new algorithm by which blurred image components are effectively removed. These studies demonstrate the possibility of the proposed method as a fast imaging technique for MR angiography.
