Objective- The aim of this study was to test the repeatability, the variability, and to establish the reference values of PW measurements in healthy Markhoz goats.Design- Retrospective study.Animals- 20 female Markhoz goats.Procedure- Using a standardized PW Doppler echocardiographic protocol, 20healthy adult unsedated female Markhoz goats were investigated three times at one-...

Objective- The purpose of this study was to investigate the feasibility of performing echocardiography in apparently healthy pigeons, and measurement of the quantitative cardiac indices using B-mode and Doppler techniques. Design- Experimental study Animals- Ten apparently healthy pigeons Procedures- Echocardi...

The authors consider the possibility of using color Doppler of the ductus venosus and the measurement of nuchal translucency as a screening test for alterations in fetal cardiac functions in the first trimester of gestation. Review of the literature suggests that the combination of the ultrasonographic measurement of nuchal translucency and Doppler at 10 and 14 weeks of gestation can be effecti...

conclusions both ua and mca doppler tests were associated with some neonatal outcomes. however, sensitivity of both ua and mca assessments was low in the prediction of adverse neonatal outcomes. by the comparison of these two methods, we found that ua doppler assessment is a better predictor of neonatal outcomes. results based on the findings, poor outcomes were detected in 48 women. nearly 17....

The frequency errors dominated by the dynamic Doppler is analyzed for mobile satellite communication systems employing fast-moving satellites. Methods are proposed and analyzed for the basestations to measure and compensate the dynamic Doppler of large range. It is shown that the proposed methods give the minimum uncertainty of the dynamic Doppler for the modem to handle. Therefore, these metho...

Real-time respiratory measurement with Doppler Radar has an important advantage in the monitoring of certain conditions such as sleep apnoea, sudden infant death syndrome (SIDS), and many other general clinical uses requiring fast nonwearable and non-contact measurement of the respiratory function. In this paper, we demonstrate the feasibility of using Doppler Radar in measuring the basic respi...
