METHOD FOR OBTAINING MULTIPLE IMAGE BY HIGH-SPEED SPIN ECHOR NMR SCAN

摘要

PURPOSE: To shorten the scan time required for acquiring NMR data for multiple images with a high-speed spin echo pulse train. CONSTITUTION: This NMR imaging system implements a series of a high-speed spin echo pulse train to acquire the data for multiple images having different contrasts weighted by T2 (1/T2 indicates an attenuation constant). Only the low-order phase-coded data are individually acquired for each image, and the scan time is sharply shortened when the common high-order phase-coded data are used for all images.
