Objectives. The aim of this study was to determine the relations between spontaneous echo
contrast, left atrial appendage blood flow velocity and thromboembolism. Background. Left …

Ultrasound imaging is one of the most important and widely used diagnostic tools in modern
medicine, second only to the conventional x-ray. Although considered a mature field …

Hemodynamic changes in the brain are often used as surrogates of neuronal activity to infer
the loci of brain activity. A major limitation of conventional Doppler ultrasound for the …

The objective of the present paper is to provide a detailed review of theoretical, experimental
and clinical works aimed at understanding the scattering of ultrasound by red blood cells …

Developing efficient brain imaging technologies by combining a high spatiotemporal
resolution and a large penetration depth is a key step for better understanding the …

The functional mapping of brain activity is essential to perform optimal glioma surgery and to
minimize the risk of postoperative deficits. We introduce a new, portable neuroimaging …

Functional ultrasound (fUS) is a novel neuroimaging technique, based on high-sensitivity
ultrafast Doppler imaging of cerebral blood volume, capable of measuring brain activation …

Over the last century, medicine has come out of the" black bag" and emerged as one of the
most dynamic and advanced fields of development in science and technology. Today …

(1). This is related in a complex way to the number of scatterers in the blood, with the
complexity due to the fact that such factors as hematocrit level, blood flow velocity, and shear …

A theory describing pulse Doppler ultrasound signals due to backscattering due to emboli in
flowing blood is presented. From this theory, the minimum detectable size of a formed …
