Microwave-induced thermoacoustic tomography (MI-TAT) is an imaging technique that exploits dielectric contrast at microwave frequencies while creating images with ultrasound resolution. We propose the use of microbubbles as a dielectric contrast agent for enhancing the sensitivity of MI-TAT for breast cancer detection. As an initial investigation of this concept, we experimentally studied the e...

Introduction As the son of an artist, I grew up surrounded by drawings, paintings, and sculpture. Perhaps for that reason, making images is central to my work as a scientist. The problem I study, organ morphogenesis, requires analysis of the cell wall. Fertile approaches stretch out in many directions (see the rest of this book) but I have been drawn to architectural problems, revealing how com...

Microwave-induced thermal acoustic imaging (MITAI) is a promising early breast cancer detection technique, in which image construction is based on thermo acoustics signals generated by the illumination of microwave pulses in tissue. In this work we have performed a microwave induced thermal acoustic signal generation simulation study using Comsol Multiphysics. A biological tissue model irradiat...

This paper presents a magnetic resonance imaging (MRI)-based virtual cystoscopy system, which extracts the bladder wall from T1-weighted MR images where the wall is enhanced while the urine and surrounding fat tissues are suppressed by a fully non-invasive imaging procedure. The system analyzes the extracted wall and detects abnormal features automatically. Test results are encouraging by FROC ...

An inverse scattering problem (ISP) for synthetic aperture radar (SAR) data in application to through-the-wall imaging is addressed. In contrast with the conventional algorithms of SAR imaging, which work linearized mathematical model based on Born approximation, fully nonlinear case considered here. To avoid local minima problem, so-called “convexification” globally convergent inversion scheme...
