Doppler Histogram Vessel Density Analysis

2013
Three-dimensional (3D) sonography and power Doppler angiography have been introduced recently as important sonographic diagnostic tools as discussed in Chap. 5. With Virtual Organ Computer-Aided Analysis (VOCAL) software, the following vascularity indices can be calculated automatically: the vascularization index (VI), flow index (FI), and ...

Blood vessel density in canine osteosarcoma.

Canadian journal of veterinary research = Revue canadienne de recherche veterinaire, 1998
Canine osteosarcoma is a prevalent bone neoplasm which has similarities to the human disease. We used a retrospective study to investigate the possibility that tumor vascularity may provide useful prognostic information, indicative of the role of this parameter in progression of this cancer.

Mast cell population density, blood vessel density and histamine content in normal human skin

British Journal of Dermatology, 1979
Mast cell population density was determined in normal skin from two regions of the arm of several healthy men and compared with blood vessel density and histamine concentration in the same sites. Mast cell and blood vessel counts were made in 1--1.5 micrometer thick plastic sections, by light microscopy and tissue-histamine concentrations were ...

Increased gingival blood vessel density in SLE patients.

Quintessence international (Berlin, Germany : 1985), 2012
Systemic lupus erythematosus (SLE) is a serious multisystem disease with a variety of cutaneous and oral manifestations. It is an autoimmune disorder whereby patients develop autoantibodies to many of their cells, cell components, and tissue. The microvascular changes in SLE play a role in the pathogenesis of this disease.

Polyp Localization in Colonoscopy Images Using Vessel Density

2018 Medical Technologies National Congress (TIPTEKNO), 2018
In this paper, we present a new approach for polyp localization in colonoscopy images. This approach is based on the determination of the polyp location using the vessel density in colon images. Primarily, we used pre-processing procedures on the colon images, and then blood vessel extraction techniques were employed.

Neutron Flux Density Effect on Vessel Steel Embrittlement

Atomic Energy, 2017
The effect of the neutron flux density on the embrittlement of the reactor vessel materials is analyzed in an investigation of the impact of neutron irradiation on their properties. The evaluation of the dependence of radiation embrittlement of the vessel steel on the neutron flux density is made to a fi rst approximation for conventional virtual ...

Two-tier vessel for photoautotrophic high-density cultures

Journal of Applied Phycology, 2015
Two-tier vessels, developed for culturing of microalgae and cyanobacteria at high cell density on a shaken platform, were assembled from a flat lower chamber to be filled with a CO2 buffer and an upper flat sterile chamber for the culture that was separated from the lower chamber by a porous polypropylene membrane.
