We report the plain film and sonographic findings in six children (2 1/2 months to 5 years old) with a subgaleal dermoid cyst at the anterior fontanelle. Plain films of the skull made in all patients showed a soft-tissue mass superficial to the anterior fontanelle with a normal subcutaneous fat layer above it. In three children, the margins of the anterior fontanelle were beveled to match the c...

This paper describes the development of a device that combines the electropalatographic measurement of tongue-palate contact with optical distance sensing to measure the mid-sagittal contour of the tongue and the position of the lips. The device consists of a thin acrylic pseudopalate that contains both contact sensors and optical reflective sensors. Application areas are, for example, experime...

Background: The aims of this study were to: (i) to analyze the morphometric characteristics cervical vertebral column in sagittal plane; and (ii) compare methods used for determinating lordosis angle. Materials Methods: Direct radiographs 175 adults analyzed angle was evaluated by Cobb (C2-C7), central angle, posterior tangent, Risser & Ferguson methods. In addition, occipitocervical (o...

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...

Background: In the current study, we investigated that how sagittal femoral bowing can affect the sagittal alignment ofthe femoral component in total knee arthroplasty (TKA).Methods: There were 25 patients underwent TKA. Long leg radiography in lateral view was performed. The sagittalfemoral bowing (SFB) and component alignment in relation to the sagittal mechanical axis and distal anterior cor...

this paper represents a new region-based active contour model that can be used to segment images with intensity non-uniformity and high level noise. the main idea of our proposed method is to use gaussian distributions with different means and variances with incorporation of intensity non-uniformity model for image segmentation. in order to integrate the spatial information between neighboring ...
