Method for generating pulse train and imaging for it and nuclear magnetic resonance tomograph, uses high frequency pulse, preceding pulses, a k-space line coding and a two-layer acquisition module for generating data

摘要

A pulse train has an alpha high frequency pulse, a preceding 180 deg pulse, a 90 deg pulse to proceed the 180 deg pulse, a k space line coding and a two-layer acquisition module subsequent to it for generating data. Using a generated pulse sequence and imaging method acquires 20 layers of an image at 16 different points in time for a matrix size of 256 x 256 during a measuring time of 8 minutes and 28 seconds.
