Figure 1. This overview image displays the 3D streamlines representing the DTI tracks, several functional areas, the vasculature and the underlying anatomy clipped at an oblique angle. The focus of this poster is the addition of the track geometry to an existing fMRI visualization application. On the right we can see the cortical spinal track (cyan) projecting from the left hand motor region (g...

the purpose of this study was to determine the influence of platform switching on stress distribution of two different implant systems using three-dimensional (3d) finite element models.six 3d finite element models were created to replicate two different implant systems with peri-implant bone tissue, in which six different implant-abutment configurations were represented: model xive-a: 3.8-mm-d...

Fig. 1. Multi-slice ECG-gated CT scan (slice thickness, 1.25 mm). (A) Contrast enhanced axial image, the right pulmonary artery was completely occluded by a mass (arrowhead). Endovascular component and extension into the surrounding pulmonary parenchyma were well shown. (B) 3D volume-rendered reconstruction (oblique view) shows the extension (arrowheads) and bronchial artery hypertrophy (arrows...

OBJECTIVES The present study was designed to test the null hypothesis that there is no difference in the fracture resistance of pulpless teeth restored with different types of post-core systems and full coverage crowns. METHODS Extracted human upper premolars were restored with a fiber post, prefabricated metallic post or cast metallic post-core. Teeth with full crown preparations without pos...

The generation of photo-realistic city model is an important task for many geospatial applications, such as 3D GIS, urban planning, virtual city tourism, car navigation, real estate, etc. The purpose of this research is to automatically generate façade texture from aerial oblique imagery. The developed algorithm can be applied to any oblique imagery taken from the air, such as UAV, airplane, or...

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...

the sofeh mountain in the south of isfahan (iran) has a development of shafts (vertical cave). simorgh cave with a depth of 42 m and a length of 52 m has developed along significant fault structures. structural analysis indicates relationships of orientation between the faults and fractures and shafts and chambers geometries. considering the main ne-sw trend of tectonic structures in the area, ...

Airborne oblique cameras such as Fairchild T-3A were initially used for military reconnaissance in 30s. A modern professional digital oblique camera such as MIDAS (Multi-camera Integrated Digital Acquisition System) is used to generate lifelike three dimensional to the users for visualizations, GIS applications, architectural modeling, city modeling, games, simulators, etc. Oblique imagery prov...

AIM To use 3D ultrasonography (3DUS) for the diagnosis of retinoblastoma. METHODS Five eyes of three children with retinoblastoma were evaluated using a commercially available computerised 3DUS system. Interactive sectioning of the stored and reconstructed 3D volumes were performed. 3DUS and histopathological findings were correlated after enucleation. RESULTS 3DUS examination revealed char...

STUDY DESIGN Retrospective radiographic study. OBJECTIVE The optimal radiographic modality for assessing cervical foraminal stenosis is unclear. Determination on conventional axial cuts is made difficult due in part to the complex, oblique orientation of the cervical neuroforamen. The utility of 3-dimensonal (3D) computed tomography (CT) reconstruction in improving neuroforaminal assessment i...
