Abstract

A simple scheme for the polarity correction of absolute images from inversion recovery multi-image T1 measurement sequences is described and demonstrated. This method is less sensitive to errors from eddy currents than the conventional full phase correction schemes and does not involve an increase in measurement time as it requires no additional scans.

摘要

本文描述并演示了一种用于反转恢复多图像T1测量序列的绝对图像极性校正的简单方案。该方法对涡流误差的敏感度低于传统的全相位校正方案，并且由于不需要额外扫描，因此不会增加测量时间。
