Single-pass Object-adaptive Data Undersampling and Reconstruction for MRI
Zhishen Huang, Saiprasad Ravishankar
There is much recent interest in techniques to accelerate the data acquisition process in MRI by acquiring limited measurements. Often sophisticated reconstruction algorithms are d…
Physics-Driven Learning of Wasserstein GAN for Density Reconstruction in Dynamic Tomography
Zhishen Huang, Marc Klasky, Trevor Wilcox +1
Object density reconstruction from projections containing scattered radiation and noise is of critical importance in many applications. Existing scatter correction and density reco…
Comparing One-step and Two-step Scatter Correction and Density Reconstruction in X-ray CT
Alexander N. Sietsema, Michael T. McCann, Marc L. Klasky +1
In this work, we compare one-step and two-step approaches for X-ray computed tomography (CT) scatter correction and density reconstruction. X-ray CT is an important imaging techniq…
Blind Primed Supervised (BLIPS) Learning for MR Image Reconstruction
Anish Lahiri, Guanhua Wang, Saiprasad Ravishankar +1
This paper examines a combined supervised-unsupervised framework involving dictionary-based blind learning and deep supervised learning for MR image reconstruction from under-sampl…
