Abstract

Deep learning for biomedical image reconstruction

Recently, deep learning approaches with various network architectures have achieved significant performance improvement over existing iterative reconstruction methods in various imaging problems. However, it is still unclear why these deep learning architectures work for specific inverse problems. To address these issues, here we show that the long-searched-for missing link is the convolutional framelets for representing a signal by convolving local and non-local bases. This discovery reveals the limitations of many existing deep learning architectures for inverse problems, and leads us to propose a novel deep convolutional framelets} neural network. Using extensive experiments with x-ray computed tomography (CT), magnetic resonance imaging (MRI), microscopy, diffuse optical tomography, ultrasound, etc, we demonstrated that our deep convolution framelets network shows consistent improvement over existing reconstruction methods.
