A Learning-from-noise Dilated Wide Activation Network for denoising Arterial Spin Labeling (ASL) Perfusion Images

no code implementations15 May 2020 Danfeng Xie, Yiran Li, Hanlu Yang, Li Bai, Lei Zhang, Ze Wang

The results showed that the learning-from-noise strategy produced better output quality than ASLDN trained with relatively high SNR reference.

Denoising Arterial Spin Labeling Cerebral Blood Flow Images Using Deep Learning

no code implementations29 Jan 2018 Danfeng Xie, Li Bai, Ze Wang

Arterial spin labeling perfusion MRI is a noninvasive technique for measuring quantitative cerebral blood flow (CBF), but the measurement is subject to a low signal-to-noise-ratio(SNR).


Tensor Based Second Order Variational Model for Image Reconstruction

no code implementations27 Sep 2016 Jinming Duan, Wil OC Ward, Luke Sibbett, Zhenkuan Pan, Li Bai

Second order total variation (SOTV) models have advantages for image reconstruction over their first order counterparts including their ability to remove the staircase artefact in the reconstructed image, but they tend to blur the reconstructed image.

Automated Segmentation of Retinal Layers from Optical Coherent Tomography Images Using Geodesic Distance

no code implementations7 Sep 2016 Jinming Duan, Christopher Tench, Irene Gottlob, Frank Proudlock, Li Bai

OCT image segmentation to localise retinal layer boundaries is a fundamental procedure for diagnosing and monitoring the progression of retinal and optical nerve disorders.
