Abstract

We present a method of multislice magnetic resonance imaging that utilizes simultaneous binary-encoded excitation. Signals are acquired from all slices at once, and the images are separated in the reconstruction process. This simultaneous multislice acquisition method has been implemented for multislice spin-echo imaging, and the results are compared with those for a standard interleaved multislice method. Advantages include improved signal-to-noise ratios and flexible slice placement. Phantom and volunteer studies are presented and evaluated in comparison with competing methods.

摘要

我们提出了一种利用同步二进制编码激发的多层磁共振成像方法。信号可一次性从所有层面采集,且图像在重建过程中被分离。这种同步多层采集方法已应用于多层自旋回波成像,并将结果与标准交错多层方法的结果进行了比较。其优点包括提高信噪比和灵活的层面放置。展示了体模和志愿者研究,并与其他竞争方法进行了比较评估。
