High-speed compressed-sensing fluorescence lifetime imaging microscopy of live cells

Proceedings of the National Academy of Sciences of the United States of America, 2020
Significance This paper describes a high-speed fluorescence lifetime imaging method, compressed-sensing fluorescence lifetime imaging microscopy (compressed FLIM), which can produce high-resolution two-dimensional (2D) lifetime images at an unprecedented

Permutation Meets Parallel Compressed Sensing: How to Relax Restricted Isometry Property for 2D Sparse Signals

, 2013
Traditional compressed sensing considers sampling a 1D signal. For a multidimensional signal, if reshaped into a vector, the required size of the sensing matrix becomes dramatically large, which increases the storage and computational complexity ...

Segmented Multistage Reconstruction of Magnetic Resonance Images

Advances in Electrical and Computer Engineering, 2021
Compressed sensing of magnetic resonance imaging refers to the reconstruction of magnetic resonance images from partially sampled k-space data. The k-space data reduces reconstruction processing time but at the cost of increasing artifacts - especially

SISSO: A compressed-sensing method for identifying the best low-dimensional descriptor in an immensity of offered candidates [PDF]

PHYSICAL REVIEW MATERIALS, 2017
The lack of reliable methods for identifying descriptors---the sets of parameters capturing the underlying mechanisms of a material's property---is one of the key factors hindering efficient materials development.

Sequential Compressed Sensing [PDF]

, 2009
Compressed sensing allows perfect recovery of sparse signals (or signals sparse in some basis) using only a small number of random measurements. Existing results in compressed sensing literature have focused on characterizing the achievable performance ...

Effect of Foot Orthoses on Midfoot Pain and the Volume of Bone Marrow Lesions in the Midfoot: A Randomized Mechanism of Action Study

Arthritis Care &Research, EarlyView.
Objective Foot orthoses are thought to improve pain by potentially modifying internal mechanical forces. To test this, we explored whether foot orthoses can modify patterns of bone marrow lesions (BMLs) in people with midfoot pain. Methods Forty‐two people were recruited with midfoot pain, and magnetic resonance imaging–confirmed midfoot BMLs ...

Blockchain-Watermarking for Compressive Sensed Images

IEEE Access, 2021
With the application of multimedia big data, the problems such as information leakage and data tampering have emerged. The security of images which is one of the most typical multimedia has become a major problem facing the large-scale open network ...

A Deep Information Sharing Network for Multi-Contrast Compressed Sensing MRI Reconstruction [PDF]

IEEE Transactions on Image Processing, 2018
Compressed sensing (CS) theory can accelerate multi-contrast magnetic resonance imaging (MRI) by sampling fewer measurements within each contrast. However, conventional optimization-based reconstruction models suffer several limitations, including a ...

Assessment of skin in patients with systemic sclerosis using high‐frequency ultrasound and shear wave elastography: A comparative study with histology, molecular and clinical parameters

Arthritis Care &Research, Accepted Article.
Objective Ultrasound (US) has been proposed as a potential tool for assessing skin fibrosis in systemic sclerosis (SSc). However, a large‐scale comparison of US‐based assessment with histological markers of skin fibrosis has not been reported. We evaluated the US‐based skin assessments for their face validity (differentiation between involved SSc and ...
