Demonstration collection for miscellaneous ECE documents. Another alternative is to create an ECE sub-community under engineering, then create multiple ECE releated collections under that sub-community.
Trust region methods for estimation of a complex exponential decay model in MRI with a single-shot or multi-shot trajectory (in review) Joint estimation of spin density, R2* decay and off-resonance frequency maps is very useful in many magnetic resonance imaging (MRI) applications. The standard multi-echo approach can achieve high accuracy but requires a ...
Characterization of Plenoptic Imaging Systems and Efficient Volumetric Estimation from Plenoptic Data Plenoptic imaging is a rapidly growing field driven by the ever-declining cost of imaging systems and the promise of image focus, perspective, and depth of field manipulation during post-processing. While plenoptic ...
On the Characterization and Reduction of Ill-Conditioning in Jointly Estimating Proton Density, T2* Decay and the Field Map We employ principal angles as a tool to demonstrate that the complex frequency is the main cause for ill-conditioning of model-based MRI reconstruction. We show that kernels of EPI and spiral trajectories have different ...
