PURPOSE To determine the feasibility of performing rapid, high-resolution, low-radiation-dose spiral CT scans of the temporal bone in unsedated pediatric patients. METHODS Axial spiral CT examinations with an effective section thickness of 1.25 mm were performed in 41 infants and children. Multiplanar reconstructions were generated using 360 degrees and 180 degrees linear interpolation algori...

OBJECTIVES To assess the 5-year survival rates and incidences of complications of cemented and screw-retained implant reconstructions. METHODS An electronic Medline search complemented by manual searching was conducted to identify randomized controlled clinical trials (RCTs), and prospective and retrospective studies giving information on cemented and screw-retained single-unit and multiple-u...

Past temperature variations are usually inferred from proxy data or estimated using general circulation models. Comparisons between climate estimations derived from proxy records and from model simulations help to better understand mechanisms driving climate variations, and also offer the possibility to identify deficiencies in both approaches. This paper presents regional temperature reconstru...

Experimental reconstructions of photon number distributions of both continuous-wave and pulsed light beams are reported. Our scheme is based on on/off avalanche photo-detection assisted by maximum-likelihood estimation and does not involve photon counting. Reconstructions of the distribution for both semiclassical and quantum states of light are reported for single-mode as well as for multi-mod...

A Simplified Approach to Fixed Metal-ceramic Reconstructions R estoring the edentulous patient with an implantsupported fixed complete denture prosthesis is a challenging procedure. Fixed metal-ceramic reconstructions are inherently different from fixed complete dentures or implant overdentures. From a prosthodontic perspective, there are 3 phases of treatment for these types of rehabilitations:

Figure 1: (A) Magnetic resonance imaging—primary sarcoma obstructing the pulmonary arteries. (B and C) Computed tomography (CT) reconstructions showing the almost complete obstruction of the bifurcation of pulmonary arteries. (D) CT angio of the reconstruction of the right ventricular outflow, main pulmonary artery and the bifurcation using homograft. (E and F) CT reconstructions of the repair ...

This paper is about the efficient generation of dense, colored models of city-scale environments from range data and in particular, stereo cameras. Better maps make for better understanding; better understanding leads to better robots, but this comes at a cost. The computational and memory requirements of large dense models can be prohibitive. We provide the theory and the system needed to crea...

Large-scale reconstructions of neuronal populations are critical for structural analyses of neuronal cell types and circuits. Dense reconstructions of neurons from image data require ultrastructural resolution throughout large volumes, which can be achieved by automated volumetric electron microscopy (EM) techniques. We used serial block face scanning EM (SBEM) and conductive sample embedding t...

The initial strength of the intact medial collateral ligament (MCL) of the elbow and the strength of 4 reconstruction techniques were compared. Twenty cadaveric upper extremities were mounted in a custom jig with the elbow at 90 degrees , and a pneumatic cyclic valgus loading protocol was used. The mean peak load to failure was 142.5+/-39.4 N for the intact ligaments and 53.0+/-9.5 N for the do...
