Driven‐equilibrium radiofrequency pulses in NMR imaging
暂无分享,去创建一个
Driven-equilibrium pulse techniques are applied to NMR imaging to extend the possibilities of manipulating image contrasts in pulse sequences with a high repetition rate. In many cases the data acquisition time can be much shorter than in more conventional pulse techniques. Both calculations and experiments reveal that the intensity of tissue with slowly relaxing nuclear magnetizations can significantly be enhanced, thus facilitating the detection of a number of pathologies.
