Our aim was to assess reproducibility of three different lumen reduction measuring methods--North American Symptomatic Carotid Endarterectomy Trial, European Carotid Surgery Trial, and common carotid--using power Doppler and color Doppler sonography before and after Levovist enhancement. We included 20 symptomatic patients with mild or severe carotid disease. North American Symptomatic Carotid ...
Video enhancement plays an important role in various video applications. It includes.1) to achieve high intra frame quality of the entire picture where multiple regions-of-interest (ROIs) can be adaptively and its well simultaneously enhanced and 2) It guarantee the inter frame quality Consistencies among video frames. HE is a useful technique for improving image contrast, but its effect is too...
BACKGROUND AND PURPOSE Magnetization transfer ratio (MTR) histogram analysis and volumetric MR imaging are sensitive tools with which to quantify the tissue destructive effects in patients with white matter or neurodegenerative disease. Our purpose was to determine whether whole brain MTR and fractional brain parenchyma volume measurements are altered in HIV-1-infected patients who are neurolog...
Integral histogram image can gather speed the computing process of feature algorithm in computer vision, butex habits high working out complexity and incompetent memory access. In this paper, we propose a configurable parallel architecture to improve the computing efficiency of integral histogram. The design in the several integral objects is well supported for an integral histogram image such ...
IntroductionPlatelet count estimation is an important element of the diagnostic and treatment process in many disorders. The present study aims to determine the incidence of improper impedance platelet count in severe microcytosis and to state the sensitivity and specificity of various parameters like histogram, red cell distribution width (RDW), mean platelet volume (MPV), platelet flags Metho...
introduction: content based image retrieval (cbir) is a method of image searching and retrieval in a database. in medical applications, cbir is a tool used by physicians to compare the previous and current medical images associated with patients pathological conditions. as the volume of pictorial information stored in medical image databases is in progress, efficient image indexing and retri...
Decreased renal perfusion plays an important role in the progression toward renal failure. In this study, a novel measure was proposed to quantify renal perfusion using canine model. Serial renal vascular images at different vascular areas including the whole vascular tree, interlobar, arcuate and interlobular vessels were captured. Image processing software was designed to analyze the changes ...
Choriocarcinoma is a highly malignant disease of trophoblastic cells, which affects young women in the reproductive years. The main sites of metastasis from choriocarcinoma are lung, vagina, liver, gastrointestinal tract and kidneys, and the involvement of the ovaries is extremely rare. The diagnosis of ovarian metastasis is made mainly by two-dimensional ultrasonography (2DUS) with color Doppl...
A new event detection scheme for power quality analysis based on the statistical analysis of adaptive decomposition signals is proposed. Proposed scheme is implemented using MATLAB Simulink DSP Blockset. The combination of an adaptive prediction filter based subband decomposition structure with a rule based histogram analysis block produced successful detection and classification results on ou...
