Development of Anatomically Realistic Numerical Breast Phantoms With Accurate Dielectric Properties for Modeling Microwave Interactions With the Human Breast
A collection of anatomically realistic 3-D numerical breast phantoms of varying shape, size, and radiographic density which can readily be used in finite-difference time-domain computational electromagnetics models of microwave interactions with the human breast. Expand

On the estimation of the worst-case implant-induced RF-heating in multi-channel MRI.
The increasing use of multiple radiofrequency (RF) transmit channels in magnetic resonance imaging (MRI) systems makes it necessary to rigorously assess the risk of RF-induced heating in multi-channel environment. Expand

Safety assessment of breast cancer detection via ultrawideband microwave radar operating in swept-frequency mode
Ultrawideband (UWB) microwave radar is a promising modality for detecting early-stage breast cancer. In our current prototype, we synthesize an antenna array by scanning a single antenna to eachExpand

Granular segregation studies for the development of a radar-based three-dimensional sensing system
The behavior of dense granular materials is difficult to measure in three-dimensions due to the opacity of the materials. We present a new radar-based sensing system that has the capability ofExpand
