ADMM-SVNet: An ADMM-Based Sparse-View CT Reconstruction Network
Photonics, 2022 In clinical medical applications, sparse-view computed tomography (CT) imaging is an effective method for reducing radiation doses. The iterative reconstruction method is usually adopted for sparse-view CT.

Reconstruction of Missing Data using Iterative Harmonic Expansion [PDF]
MNRAS (October 11, 2016) 462 (1): 588-600, 2013 In the cosmic microwave background or galaxy density maps, missing fluctuations in masked regions can be reconstructed from fluctuations in the surrounding unmasked regions if the original fluctuations are sufficiently smooth. One reconstruction method involves applying a harmonic expansion iteratively to fluctuations in the unmasked region.

Iterative reconstruction of the transducer surface velocity [PDF]
IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2013 Ultrasound arrays used for medical imaging consist of many elements placed closely together. Ideally, each element vibrates independently. However, because of mechanical coupling, crosstalk between neighboring elements may occur. To quantify the amount of crosstalk, the transducer velocity distribution should be measured.

Iterative Forward-Backward Pursuit Algorithm for Compressed Sensing
Journal of Electrical and Computer Engineering, 2016 It has been shown that iterative reweighted strategies will often improve the performance of many sparse reconstruction algorithms. Iterative Framework for Sparse Reconstruction Algorithms (IFSRA) is a recently proposed method which iteratively enhances ...
