Automatic identification and extraction of bone contours from x-ray images is an essential first step task for further medical image analysis. In this paper we propose a 3D statistical model based framework for the proximal femur contour extraction from calibrated x-ray images. The automatic initialization to align the 3D model with the x-ray images is solved by an Estimation of Bayesian Networ...

<p>Isolated fractures of the shaft femur are relatively common injuries. Ipsilateral multifocal less with an additional proximal femoral fracture estimated to occur in up 5% diaphyseal and distal occurring 3-4%. Trifocal consisting ipsilateral proximal, diaphyseal, extremely rare. These patterns seen young adult population following high velocity trauma such as fall from height road traff...

central to vygotsky-inspired sociocultural theory (sct) is the notion of zpd seen by sla researchers as a useful framework within which l2 teaching and learning can take place. van lier (2004) argues that the zpd could be activated in diverse proximal contexts (pcs) and is not limited to the expert-novice scenario. . this study probed whether iranian efl learners' collaborative task performance...

In many clinical applications, 3D reconstruction of patient-specific structures is major interest. Despite great effort put in 2D-3D reconstruction, gold standard bone obtained by segmentation on CT images still mostly used – at the expense exposing patients to significant ionizing radiation and increased health costs. State-of-the-art methods are based non-rigid registration digitally reconstr...

AIM Resin infiltration of proximal lesions is a new approach to stopping caries progression. Therefore, the aim of the present study was to evaluate four-year efficacy of proximal infiltrates in adolescents. MATERIALS AND METHODS In ten adolescents, a total of 21 proximal infiltrates (ICON® (DMG, Germany) were applied to initial proximal lesions of permanent incisors and premolars according t...

A 29-year-old female presented with an unusual case of Wallenberg's syndrome due to a dissecting aneurysm of the posterior inferior cerebellar artery (PICA) manifesting as a sensation of heaviness in the occipital region and vertigo. Magnetic resonance imaging revealed infarction of the lateral aspect of the medulla oblongata. Digital subtraction angiography (DSA) revealed a spindle-shaped dila...

The reticular motility in 144 cattle with vagal indigestion was evaluated by ultrasonography; 97 had proximal functional stenosis (reticulo-omasal stenosis) and 47 had distal functional stenosis (pyloric stenosis). A 3.5 MHz linear transducer was used to measure the frequency, amplitude, duration and speed of the reticular contractions per three minutes while the animals were standing and unsed...

Contour Crafting is an emerging technology that uses robotics to construct free form building structures by repeatedly laying down layers of material such as concrete. The Contour Crafting technology scales up automated additive fabrication from building small industrial parts to constructing buildings. Tool path planning and optimization for Contour Crafting benefit the technology by increasin...

statement of problem: dental caries is one of the common diseases in the world. it is an infective disease which is caused by loss of minerals and destruction of dental tissues. one of the most effective ways to diagnose the interproximal caries is radiography. bitewing radiography is the best way for caries diagnosis. purpose: the aim of this study was to evaluate the prevalence of the interpr...
