摘要

本文提出了一种利用FastICA分离功能MRI序列组分的新方法。在本文中，我们将证明，如果我们从其他主成分中减去背景(通过PCA从源中分离)，算法收敛得非常快。所提出的方法比以前用于功能MRI序列中组分分离的方法更具鲁棒性和计算效率。

A New Approach for Separation of Functional MRI Images' Components Using Modified FastICA Algorithm

This paper proposes a new approach for separation of components in functional MRI sequences using FastICA. In this paper we will demonstrate that if we subtract background (which is separated from sources by PCA) from other principal components, the algorithm converges very fast. The proposed method is more robust and much more computationally efficient than methods, which previously has been applied for separation of components in functional MRI sequences.
