Multidimensional 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 کاملUltrasound Frontiers: 3D Doppler, Automatic Fetal Biometry, Handheld Ultrasound
Ultrasound frontiers are infinitive and some recent developments are discussed in this review. The author aims to provide the reader with the definition of 3D Doppler and its potential clinical applications. It also describes automatic fetal biometry and discusses clinical potentials of handheld ultrasound. The rapid development of these new sonographic techniques will continue to enlarge the s...
متن کاملAdvances 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 کامل[Doppler ultrasound velocimetry for fetal surveillance: critical analysis].
A avaliação da vitalidade fetal é, sem dúvida, de grande utilidade em Obstetrícia, sendo a dopplervelocimetria um dos métodos disponíveis para essa finalidade. Na atualidade, apesar do reconhecimento da utilidade da dopplervelocimetria para avaliação do bem-estar fetal, tem sido necessário que se reflita sobre que casos realmente se beneficiam dessa tecnologia e também sobre algumas particulari...
متن کاملDoppler ultrasound assessment of fetal anaemia in an alloimmunised pregnancy
Introduction While the use of elevated middle cerebral artery peak systolic velocity (MCA PSV) in assessing fetal anaemia is well known, its occurrence is uncommon due to the current practice of giving prophylactic doses of ultrafiltered Rh (D) immunoglobulin (anti-D) in Rh (D) negative women. In mothers who do not receive prophylaxis with Rh immunoglobulin, the overall risk of immunisation for...
