An ultra-wideband microwave imaging system that employs a heterogeneous breast phantom and covers the ultrawideband (UWB) frequency range (3.1 GHz to 10.6 GHz) is presented. The platform scanning system allows monostatic and bistatic mode of operation. In this work, developed heterogeneous phantoms are used to mimic the realistic breast tissues. A utilized tapered slot antenna array allows for ...

Diffuse photon density waves have lately been used both to characterize diffusive media and to locate and characterize hidden objects, such as tumors, in soft tissue. In practice, most biological media of medical interest consist of various layers with different optical properties, such as the fat layer in the breast or the different layers present in the skin. Also, most experimental setups co...

BACKGROUND AND PURPOSE The diagnosis of dural sinus thrombosis is often difficult because of its variable and nonspecific clinical presentation and the overlapping signal intensities of thrombosis and venous flow on conventional MR images and MR venograms. We compared 3D contrast-enhanced magnetization-prepared rapid gradient-echo (MP-RAGE) sequences with 2D time-of-flight (TOF) MR venography, ...

ionospheric slab thickness is defined as the ratio of tec to maximum electron density of the f-region (nmf2), proportional to the square of the f2-layer critical frequency (fof2). it is an important parameter in that it is linearly correlated with scale height of the ionosphere, which is related to electron density profile. it also reflects variation of the neutral temperature. therefore, ionos...

Abstract Tectonic processes control hot spring temperature and geochemistry, yet how this in turn shapes microbial community composition is poorly understood. Here, we present geochemical 16 S rRNA gene sequencing data from 14 springs contrasting styles of subduction along a convergent margin the Peruvian Andes. We find that tectonic influence on geochemistry composition. Hot flat-slab back-arc...

Tumours are heterogenous growths that consists of different types cells with varying genetic expressions. The complex structure the tumour makes cancer treatment difficult due to heterogeneity each react differently radiation treatment. Therefore, effective requires proper characterization heterogeneity, which is be assessed by most current medical imaging technologies. purpose this study was d...
