Microwave tomography has been proven to successfully reconstruct the dielectric profile of a human breast when used in breast imaging applications, thereby providing an alternative to other imaging modalities. However, the method suffers from high computational requirements which restrict its use in practical imaging systems. This paper presents a novel parallelization strategy to accelerate mi...

Time reversal imaging method based on full wave numerical technique for likely breast tumors biological tissue in the Microwave-Induced Thermo-Acoustic Tomography (MITAT) system is discussed. In this paper, the mechanism of microwave-induced thermo-acoustic is strictly described based on thermodynamics and thermo-diffusion principles; the equivalent relationship between the absorbed microwave e...

Microwave testing has the advantage of detecting surface and sub-surface flaws and anomalies under coatings, paint or dirt. Thus, major application of microwave sensors is imaging to determine the shape, size, and location of buried flaws using scattered field measurements. A typical microwave system consists of transmitting and receiving antennas and requires that both sides of the material un...

BACKGROUND AND PURPOSE High-resolution MR imaging is an emerging tool for evaluating intracranial artery disease. It has an advantage of defining vessel wall characteristics of intracranial vascular diseases. We investigated high-resolution MR imaging arterial wall characteristics of CNS vasculitis and reversible cerebral vasoconstriction syndrome to determine wall pattern changes during a foll...

Microwave imaging techniques have shown excellent capabilities in various fields such as civil engineering, nondestructive testing, industrial applications, and have in recent decades experienced strong growth as a research topic in biomedical diagnostics. Many research groups throughout the world work on prototype systems for producing images of human tissues in different biomedical applicatio...

In this paper, we compare the performance of multilook application for sparse microwave imaging with two different linear models. One is based on the inverse of conventional multilook procedures with frequency-domain multilook observation (FMO) and the other employs the decomposition of synthetic aperture to yield a time-domain multilook observation (TMO). From the comparisosn, we found that FM...

Many proposed extensions of the standard model of particle physics predict the existence of weakly interacting sub-eV particles (WISPs) such as hidden-sector photons and axions, which are also of interest as dark matter candidates. In this paper we propose a novel experimental approach in which microwave photonic lattice structures form part of a ‘light shining through the wall’-type experiment...

Protective capabilities were studied of carboxymethylated (1-->3)-beta-D-glucan from Saccharomyces cerevisiae cell wall against lipid peroxidation in phosphatidylcholine liposomes induced by OH radicals produced with Fenton's reagent (H2O2/Fe2+) and also by microwave radiation using absorption UV-VIS spectrophotometry. A significant decrease in the conjugated diene production, quantified as Kle...
