高空间分辨率的磁共振图像(MRI)提供了详细的解剖学信息，通常是精确定量分析所必需的。然而，高空间分辨率通常是以较长的扫描时间、较少的空间覆盖和较低的信噪比为代价的。单幅图像超分辨率(SISR)是一种从单一低分辨率(LR)输入图像恢复高分辨率(HR)细节的技术，近年来深度学习的突破使其得到了极大的改善。本文提出了一种新的神经网络结构--三维密集连接超分辨率网络(DCSRN)来恢复结构脑MR图像的HR特征。通过对1113个被试的数据集的实验，我们证明了我们的网络在恢复4x分辨率降低的图像方面优于双三次插值和其他深度学习方法。

英文摘要：
Magnetic resonance image (MRI) in high spatial resolution provides detailed anatomical information and is often necessary for accurate quantitative analysis. However, high spatial resolution typically comes at the expense of longer scan time, less spatial coverage, and lower signal to noise ratio (SNR). Single Image Super-Resolution (SISR), a technique aimed to restore high-resolution (HR) details from one single low-resolution (LR) input image, has been improved dramatically by recent breakthroughs in deep learning. In this paper, we introduce a new neural network architecture, 3D Densely Connected Super-Resolution Networks (DCSRN) to restore HR features of structural brain MR images. Through experiments on a dataset with 1,113 subjects, we demonstrate that our network outperforms bicubic interpolation as well as other deep learning methods in restoring 4x resolution-reduced images.
