METHOD AND DEVICE TO FORM IMAGES OF MAGNETIC RESONANCE Russian patent published in 2003 - IPC

Abstract RU 2216751 C2

FIELD: generation of images with use of magnetic resonance of object placed in static magnetic field. SUBSTANCE: method includes simultaneous measurement of series of families of magnetic resonance signals by employment of gradients and network of induction coils of receiving facility, formation of series of images of induction coils of receiving facility from families of measured magnetic resonance signals and formation of final image from sensitivity of induction coils of receiving facility depending on distance and of first assemblage of images of induction coils of receiving facility of device. Number of stages of phase coding corresponding to gradient of phase coding is decreased by means of conversion coefficient by comparison with standard formation of Fourier image with preservation of same field of vision as in process of standard formation of Fourier image. Computation of complex matrix inversion can be simplified with the aid of determination of vector of final image from combination of generalization of sensitivity matrix and vector of image of induction coils of receiving facility. EFFECT: diminished artifact of mixing in final image and possibility of utilization of noninteger conversion factors. 10 cl, 4 dwg
