Automated ultrasound assessment of amniotic fluid index using deep learning

چکیده

The estimation of antenatal amniotic fluid (AF) volume (AFV) is important as it offers crucial information about fetal development, well-being, and perinatal prognosis. However, AFV measurement cumbersome patient specific. Moreover, heavily sonographer-dependent, with accuracy varying greatly depending on the sonographer’s experience. Therefore, development accurate, robust, adoptable methods to evaluate highly desirable. In this regard, automation expected reduce user-based variability workload sonographers. automating very challenging, because accurate detection AF pockets difficult owing various confusing factors, such reverberation artifact, mimicking region floating matter. Furthermore, pocket exhibits an unspecified variety shapes sizes, ultrasound images often show missing or incomplete structural boundaries. To overcome abovementioned difficulties, we develop a hierarchical deep-learning-based method, which consider clinicians’ anatomical-knowledge-based approaches. key step segmentation using our proposed deep learning network, AF-net. AF-net variation U-net combined three complementary concepts - atrous convolution, multi-scale side-input layer, side-output layer. experimental results demonstrate that method provides index (AFI) robust precise from clinicians. achieved Dice similarity 0.877±0.086 for mean absolute error 2.666±2.986 relative 0.018±0.023 AFI value. best knowledge, first time, automated AFI.

assessment of the efficiency of s.p.g.c refineries using network dea

data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...

The predictive value of ultrasound assessment of amniotic fluid index, biophysical profile score, nonstress test and foetal movement chart for meconium-stained amniotic fluid in prolonged pregnancies.

OBJECTIVE To evaluate the value of non-stress test (NST), biophysical profile score (BPS), amniotic fluid index (AFI) and foetal movement charted (FMC) by mother in the prediction of meconium passage in post-date pregnancies. METHODS In a cross-sectional study performed from 2003 to 2005, in the Ali-Ebne-Abitaleb Hospital, all post-date singleton pregnant women were included and evaluated a f...

radial amniotic fluid index as a new and accurate method for measurment of amniotic fluid volume

amniotic fluid volume (afv) is one of the important parameters in the assessment of fetal well-being. the ability of ultrasound measurements to represent the actual afv is unproven. this study was undertaken to compare correlation of conventional amniotic fluid index (afi) and radial amniotic fluid index (rafi) as a new method with actual fluid volume on phantom. as an experimental study, 10 to...

Towards Automated Tuberculosis detection using Deep Learning

Tuberculosis(TB) in India is the world’s largest TB epidemic [1]. TB leads to 480,000 deaths every year [2]. Between the years 2006 and 2014, Indian economy lost US$340 Billion due to TB. This combined with the emergence of drug resistant bacteria in India makes the problem worse [3]. The government of India has hence come up with a new strategy which requires a high-sensitivity microscopy base...
