Assessment of umbilical arterial and venous flow using color Doppler.
OBJECTIVE To estimate the umbilical artery and vein blood volume flow using B-mode and Doppler ultrasound in the second and third trimesters of pregnancy. DESIGN This was a cross-sectional study of 129 singleton, healthy pregnancies at 23-33 weeks' gestation. The umbilical artery and vein cross-sectional area, time-averaged velocity and pulsatility index were measured in a free loop of cord, ...
متن کاملPatterns of Cavernosal Arterial Flow in Patients with Erectile Dysfunction, as Evaluated by Color Doppler Flowmetry
Background: Erectile dysfunction (ED) is a growing common health problem that affects men of different age groups. Despite it is thought to be a para-aging disease, it affects young and middle aged men as well. Color duplex Doppler is a non-invasive tool of evaluation of the vascular mechanism of erection in patients suspected to have an organic cause of ED. Objective: To demonstrate the color ...
متن کاملMathematical modelling of Sisko fluid flow through a stenosed artery
In the present study, the nonlinear model of non-Newtonian blood flow in cosine-shape stenosed elastic artery is numerically examined. The model is carried out for axisymmetric, two-dimensional and fully developed blood flow. The vessel wall is assumed to be have time-dependent radius that is important factor for study of blood flow. The cosine-shape stenosis convert to rigid artery by using a ...
متن کاملBetter Flow Estimation from Color Images
One of the difficulties in estimating optical flow is bias. Correcting the bias using the classical techniques is very difficult. The reason is that knowledge of the error statistics is required, which usually cannot be obtained because of lack of data. In this paper, we present an approach which utilizes color information. Color images do not provide more geometric information than monochromat...
متن کاملScene Flow from Depth and Color Images
In this paper we consider the problem of estimating a 3D motion field using multiple cameras. In particular, we focus on the situation where a depth camera and one or more color cameras are available, a common situation with recent composite sensors such as the Kinect. In this case, geometric information from depth maps can be combined with intensity variations in color images in order to estim...
