Advances in Doppler Ultrasound Signal Processing for Fetal Monitoring
The fetal monitoring is based on a fetal heart rhythm analysis, and aimed at the detection of early symptoms of the intrauterine fetal hypoxia. The most often used method for acquisition of the fetal heart rate (FHR) during pregnancy is the Doppler ultrasound technique. When a penetrating beam is reflected from the moving parts, like valves of the fetal heart, its frequency is shifted according...
متن کاملMultidimensional Ultrasound Doppler Signal Analysis for Fetal Activity Monitoring.
Fetal activity parameters such as movements, heart rate and the related parameters are essential indicators of fetal wellbeing, and no device provides simultaneous access to and sufficient estimation of all of these parameters to evaluate fetal health. This work was aimed at collecting these parameters to automatically separate healthy from compromised fetuses. To achieve this goal, we first de...
متن کاملCardiotocography only versus cardiotocography plus ST analysis of fetal electrocardiogram for intrapartum fetal monitoring: a Swedish randomised controlled trial.
BACKGROUND Previous studies indicate that analysis of the ST waveform of the fetal electrocardiogram provides information on the fetal response to hypoxia. We did a multicentre randomised controlled trial to test the hypothesis that intrapartum monitoring with cardiotocography combined with automatic ST-waveform analysis results in an improved perinatal outcome compared with cardiotocography al...
متن کاملThe Effects of Sildenafil on Fetal Doppler Indices: A Systematic Review and Meta-Analysis
Background & Objective: Sildenafil citrate is a potential new strategy for the management of intrauterine growth restriction (IUGR) and preeclampsia, although its efficacy still needs to be approved. Accordingly, the aim of this study was to systematically assess the effectiveness of sildenafil on improving fetal Doppler indices, as well as the most common adverse effects of sildenafil. ...
متن کاملClinical application of three-dimensional ultrasound in fetal brain assessment.
AIM To clarify the usefulness of three-dimensional (3D) ultrasound in the assessment of the fetal head and brain, according to 3D ultrasound surface reconstruction, multiplanar image analysis, three-dimensional angiography, and volume calculation. METHODS We examined 326 normal fetuses between 10 and 40 weeks of gestation using 3D ultrasound (Voluson, 530D, Medison, Seoul, Korea), mainly with...
