Ultrasound is a fast, cost-effective, and noninvasive imaging modality increasingly being used as a diagnostic tool in emergency departments, at bedside, and in the clinic. Its portability and easy operation makes ultrasound accessible to medical professionals in all specialties and stages of training. However, the unique geometry and contrast of structures on ultrasound sections often appear c...

Ultrasound analysis plays an important role in the assessment of morphology of different forms of cancerous lesions. However, owing to the large number of false positive results, the accuracy of the technique has been largely restrictive in nature. Pulsed Doppler spectral analysis and color Doppler imaging enable the evaluation of blood vessel distribution, tumor blood flow, and quantitative me...

background: with the technical development, ultrasound tends to overpass its limits and to become the main investigation tool even for situations when it was traditionally considered second best. it is more convenient both for patient and doctor, less expensive and has real diagnostic value. objective: the present paper, and its graphic back-up, are intended as a visual testimony of the fact th...

Alkali-activated materials (AAMs) have been extensively studied due to their high performance and low carbon emissions. However, the long-term durability of AAMs remains a major concern, which is closely related microstructures pore networks. X-ray computed tomography (CT) has emerged as powerful non-destructive technique for threedimensional microstructural analysis in field civil engineering....

The fabrication of three-dimensional (3D) diamond photonic crystals with controllable nanoroughness (≤120 nm) on the surface from epoxy-functionalized cyclohexyl polyhedral oligomeric silsesquioxanes (POSS) is reported. The nanoroughness is generated on the 3D network due to microphase separation of the polymer chain segments in a nonsolvent during the rinsing step in holographic lithography pr...
