INTRODUCTION Many physicians target the interventricular septum for pacemaker implantation, but the lead may inadvertently end up in an anterior position. AIMS We sought to compare two stylet shapes to achieve mid-septal lead placement, as well as the utility of a novel right anterior oblique (RAO) fluoroscopic landmark. METHODS AND RESULTS Patients undergoing pacemaker implantation were en...

OBJECTIVE To evaluate the benefit of three-dimensional (3D) ultrasound in the examination of the fetal nasal bone at 11-14 weeks of gestation. METHOD We examined the fetal nasal bone in 120 stored volumes acquired transabdominally with a 3D scanner from singleton pregnancies at 11-14 weeks of gestation. The volume acquisition had been performed following conventional ultrasound examination th...

plagiocephaly (oblique skull) is premature fusion of one of the coronal sutures. frontal plagiocephaly is a rare congenital deformity in the skull that is the most complicated form of craniosynostosis to treat. examination of all sutures is necessary for diagnosis of craniosynostosis in this article, a 10-month-old, healthy girl with deformity of the right forehead and orbit that is caused by f...

From a single view that contains a three dimensional scene is possible to obtain substantial information about the object and even its partial reconstruction. This analysis can provide, in the case of Photogrammetry, measures of the original object, and in the case of Computer Vision, useful information to 3D reconstruction. Nevertheless, to carry out this analysis, a critical part of the proce...

It is proposed to use a single base platform in the Persian Gulf considering its low depth and more appropriate environmental conditions in comparison to North Sea and Mexico Gulf where this kind of platform is very popular. The pile of platform is responsible for transmission of environmental loads resulted from waves, currents, wind and dead loads to foundation of platform. Using SACS 5.3 sof...

Hip fractures due to osteoporosis are accompanied with increased mortality and morbidity. Bone mineral density (BMD [g/cm(2)]) measured by dual-energy X-ray absorptiometry (DXA) is the most important risk factor. However, an overlap exists between results of fractured and nonfractured populations. Macro-architectural parameters of the femur are independent risk factors of fracture. They have be...

Radiol Bras. 2016 Mar/Abr;49(2):V–VI The use of fast spin-echo (FSE) magnetic resonance imaging (MRI) sequences is the most versatile way of evaluating the musculoskeletal system. Anisotropic, two-dimensional (2D) sequences have greater resolution in the acquisition plane whereas the voxel resolution in isotropic three-dimensional (3D) volumetric sequences is the same in all planes with no loss...

Oblique photogrammetry-based three-dimensional (3D) urban models are widely used for smart cities. In 3D models, road signs small but provide valuable information navigation. However, due to the problems of sliced shape features, blurred texture and high incline angles, cannot be fully reconstructed in oblique photogrammetry, even with state-of-the-art algorithms. The poor reconstruction common...
