Grayscale Analysis of Carotid Plaque: An Overview

Colorization of Grayscale Images: an Overview

An efficient colorization scheme for images based on prioritized source propagation is proposed in this work. A user first scribbles colors on a set of source pixels in an image. The proposed algorithm then propagates those colors to the other non-source pixels and the subsequent frames. Specifically, the proposed algorithm identifies the non-source pixel with the highest priority, which can be...

an infinite planar array of rectangular microstrip patch antenna analysis

the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...

Atherosclerotic plaque rupture: an overview

Symptomatic ulcerative carotid plaque.

A 65-year-old man with a history of smoking, hypertension, and diabetes mellitus presented because of sudden-onset left hemiparesis. On admission, neurological examination disclosed a mild left-sided weakness, a normal consciousness level, and a right carotid bruit. The blood pressure, ECG, echocardiogram, and laboratory studies were all unremarkable. He was taking daily aspirin, enalapril, and...

The symptomatic carotid plaque.

BACKGROUND The natural histories of equally severe symptomatic and asymptomatic carotid stenoses are very different, which suggests dichotomy in plaque behavior. The vascular biology of the symptomatic carotid plaque is presented in this review. SUMMARY OF REVIEW Histology studies comparing asymptomatic and symptomatic plaques were identified from MEDLINE. Reports in which stenosis severity w...
