Low-dose CT denoising with convolutional neural network

Understand

To reduce the potential radiation risk, low-dose CT has attracted much attention.

• However, simply lowering the radiation dose will lead to significant deterioration of the image quality.
• In this paper, we propose a noise reduction method for low-dose CT via deep neural network without accessing original projection data.
• A deep convolutional neural network is trained to transform low-dose CT images towards normal-dose CT images, patch by patch.
