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 ...
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 ...
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 ...
AU Smart Cart Senior Design Project Report Fall 2012
Team 3 consists of six members working together to design and build a fully autonomous shopping cart. The purpose of the cart is to perform as a personal shopping assistant to the user as he/she shops in different environments. ...
