Hu Chen, Yi Zhang, Weihua Zhang, Peixi Liao, Ke Li, Jiliu Zhou, Ge Wang

摘要:

为了降低潜在的辐射风险,低剂量CT受到越来越多的关注。然而,简单地降低辐射剂量将显著降低成像质量。在本文中,我们提出了一种通过深度学习进行低剂量CT降噪的方法,而无需访问原始投影数据。深度卷积神经网络的架构被认为是将低剂量CT图像逐块映射到其对应的正常剂量CT图像。定性和定量评价表明,所提出的方法的最先进的性能。

英文摘要:

In order to reduce the potential radiation risk, low-dose CT has attracted more and more attention. However, simply lowering the radiation dose will significantly degrade the imaging quality. In this paper, we propose a noise reduction method for low-dose CT via deep learning without accessing the original projection data. An architecture of deep convolutional neural network was considered to map the low-dose CT images into its corresponding normal-dose CT images patch by patch. Qualitative and quantitative evaluations demonstrate a state-the-art performance of the proposed method.
