Abstract
It has been shown that magnetic resonance image data can be corrected for the effects of motion by using retrospective adaptive techniques which employ navigator (NAV) echoes. We demonstrate the accuracy with which NAV echoes can measure motion, as well as the independent nature of the respective view-to-view and intraview corrections.
摘要
已经表明，通过使用采用导航（NAV）回波的回顾性自适应技术，可以校正磁共振图像数据的运动影响。我们展示了NAV回波测量运动的准确性，以及各个视图间和视图内校正的独立性。
