introduction: accurate estimation of gestational age (ga) early in pregnancy is necessary for obstetric care decisions and for determining fetal growth and other conditions that may need intervention or delivery. this study was aimed to compare m enstrual versus ultrasound scan-based gestational age estimates of ga in kermanshsh during 2004-2005. materials and methods: a diagnostic study was do...

Accurate prenatal estimation of birth weight is useful in the management of labour and delivery. This study compared the accuracy of ultrasound, clinical and maternal estimates of fetal weight in 246 parous women with singleton, term pregnancies admitted for scheduled caesarean section. The sensitivity and specificity of predicting birth weight by ultrasound measures were 12.6% and 92.1%, by cl...

BACKGROUND Accurate determination of fetal weight prior to delivery can have a significant bearing on the management decision in labour, thereby markedly improving perinatal outcome. OBJECTIVE To determine the accuracy of prediction of birth weight by fetal ultrasound. METHODS This is the retrospective observational hospital based study done at Kathmandu medical college teaching hospital, S...

This paper proposes a fetal gender and weight estimation method using ultrasound images. Normally the gender and weight estimation is done by the physician through the observation only. The accuracy of the gender and weight estimation strongly dependent on the experiences of the physician as the images of ultrasound are not clear for those low cost two dimension (2D) ultrasound. In order to inc...

Ultrasound elastography is a promising imaging technique that can assist in diagnosis of thyroid cancer. However, the complexity of the tissue movements under freehand compression requires the use of a parametric displacement model and a specific estimation method adapted to sub-pixel motion. Therefore, the aim of this study was to develop a motion estimation method for ultrasound elastography ...

Tissue deformation in ultrasound imaging is an inevitable phenomenon and poses challenges to the development of many techniques related to ultrasound image registration, including multimodal image fusion, freehand three-dimensional ultrasound, and quantitative measurement of tissue geometry. In this thesis, a novel trajectory-based method to correct tissue deformation in ultrasound B-mode imagi...
