METHOD FOR INSPECTION USING NUCLEAR MAGNETIC RESONANCE AND ITS APPARATUS

摘要

PURPOSE: To obtain a chemical shift image with an improved N/S ratio by a method wherein a plurality of chemical shift images based on each corresponding echo train signal obtd. in each process are prepd. and corresponding pixels of each chemical shift image are added together. CONSTITUTION: An inclined magnetic field Gr for lead out is applied on an inclined magnetic field Gx by making a spin echo signal coincide with a measuring time to generate an echo train signal Sig1 contg. both a space information in the X axis direction and a chemical shift information. Then, after the echo train signal is divided respectively into a group of the odd number-th echos and a group of the even number-th echos, they are rearranged into a three- dimensional data arrangement which scans kδ axis, kx axis and ky axis of the three-dimensional k space connected with δ axis, X axis and Y axis of the three-dimensional real space chemical shift by Fourier transformation. Thereafter, a new chemical shift image is prepd. by adding informations of corresponding coordinates each other.
