摘要:

磁共振成像是一种功能强大的成像方式,可以提供多方面的信息,但它有一个瓶颈问题“成像速度慢”。减少扫描的测量可以加速MR成像与强大的重建方法的帮助下,已经从线性分析模型的非线性迭代的。这一领域的新趋势是用从数据中学习的信号模型取代人类定义的信号模型。具体而言,从2016年开始,深度学习已被纳入快速MR成像任务,该任务从大数据集中提取有价值的先验知识,以促进从有限的测量中进行准确的MR图像重建。本次调查旨在回顾2016年至2020年6月期间基于深度学习的MR图像重建工作,并将讨论与此类方法相关的优点,局限性和挑战。最后但并非最不重要的是,本文将通过指出良好的教程资源,最先进的开源代码和有意义的数据源,为有兴趣为这一领域做出贡献的研究人员提供一个起点。

英文摘要:

Magnetic resonance imaging is a powerful imaging modality that can provide versatile information but it has a bottleneck problem "slow imaging speed". Reducing the scanned measurements can accelerate MR imaging with the aid of powerful reconstruction methods, which have evolved from linear analytic models to nonlinear iterative ones. The emerging trend in this area is replacing human-defined signal models with that learned from data. Specifically, from 2016, deep learning has been incorporated into the fast MR imaging task, which draws valuable prior knowledge from big datasets to facilitate accurate MR image reconstruction from limited measurements. This survey aims to review deep learning based MR image reconstruction works from 2016- June 2020 and will discuss merits, limitations and challenges associated with such methods. Last but not least, this paper will provide a starting point for researchers interested in contributing to this field by pointing out good tutorial resources, state-of-the-art open-source codes and meaningful data sources.
