基于深度学习的MEG源定位

MEG Source Localization via Deep Learning

Dimitrios Pantazis, Amir Adler

摘要:

我们提出了一种深度学习解决方案,以解决脑磁图(MEG)大脑信号的定位问题。所提出的深度模型架构针对单个和多个时间点MEG数据进行调整,并且可以估计不同数量的偶极子源。从模拟脑磁图数据上的一个真正的人类受试者的皮质表面的结果表明,在特定的情况下,不同的SNR水平,源间相关值,和源的数量的改进对流行的RAP-MUSIC定位算法。重要的是,深度学习模型具有强大的性能来转发模型误差,并将计算时间显著减少到1 ms的一小部分,为实时MEG源定位铺平了道路。

英文摘要:

We present a deep learning solution to the problem of localization of magnetoencephalography (MEG) brain signals. The proposed deep model architectures are tuned for single and multiple time point MEG data, and can estimate varying numbers of dipole sources. Results from simulated MEG data on the cortical surface of a real human subject demonstrated improvements against the popular RAP-MUSIC localization algorithm in specific scenarios with varying SNR levels, inter-source correlation values, and number of sources. Importantly, the deep learning models had robust performance to forward model errors and a significant reduction in computation time, to a fraction of 1 ms, paving the way to real-time MEG source localization.
