This study describes the first case of biliary peritonitis after radiofrequency ablation diagnosed by magnetic resonance (MR) imaging with gadolinium ethoxybenzyl diethylenetriaminepentaacetic acid (Gd-EOB-DTPA), a hepatocyte-specific MR imaging contrast agent. The image acquired 300 minutes after the administration of Gd-EOB-DTPA was useful to make a definite diagnosis and to identify the path...

The paper discussed pipeline inner-outer defects inspection and identification methods in pipeline magnetic flux leakage (MFL) inspection. Inspection vehicle got across defects in some velocity, bringing residual MFL, its signal frequency and peak value depend on defects size, defects shape, defects in inner or outer, inspected by Hall element sensors. The results of this research indicate diff...

Rupture of a right hepatic artery pseudoaneurysm into the gallbladder is very rare. We demonstrated a 20-mm dumbbell-shaped pseudoaneurysm in the gallbladder lumen by using contrast-enhanced magnetic resonance angiography in a 73-year-old man with acute right upper abdominal pain. Inflammation of the gallbladder caused by calculous cholecystitis, which leads to biliary leakage and erodes the ri...

Deformable models often require some degree of user-interaction to produce an accurate segmentation of the feature object. We propose an automatic deformable surface for segmenting the femur from magnetic resonance volumes of the knee. In order to overcome the limitations of many existing deformable models, probabilistic labelling is used to drive the deformation process, together with a surfac...

The paper deals with magnetic shields for distribution systems mainly devoted to MV/LV substation. In the category of passive system, a new multilayer shielding plate is presented. The main purpose of the proposed solution is the reduction of the gap between the ferromagnetic sheets by a proper overlapping in order to reduce the local leakage fluxes. Plates characterised by different conductive...

We report the utility of contrast-enhanced magnetic resonance cholangiography (MRC) using gadoxetic acid (Gd-EOB-DTPA) in the diagnosis of bronchobiliary fistula associated with liver hydatid cyst. Contrast-enhanced MRC clearly delineated the leakage of contrast agent from the biliary duct and its communication with the bronchial tree. Providing functional information about physiologic or patho...

The traditional grid-connected PV inverter includes either a line frequency or a high frequency transformer between the inverter and grid. The transformer provides galvanic isolation between the grid and the PV panels. In order to increase the efficiency, to reduce the size and cost, the effective solution is to remove the isolation transformer. It leads to appearance of common mode (CM) ground...

Quantum-dot spin qubits characteristically use oscillating magnetic or electric fields, or quasi-static Zeeman field gradients, to realize full qubit control. For the case of three confined electrons, exchange interaction between two pairs allows qubit rotation around two axes, hence full control, using only electrostatic gates. Here, we report initialization, full control, and single-shot read...

This paper reports on a feasibility study of using eddy current (EC) and magnetic flux leakage (MFL) methods to detect corrosion damage in rebars that anchor concrete barrier rails to the road deck of bridge structures. EC and MFL measurements were carried out on standalone rebars with and without artificial defects of 25% and 50% material loss, using a commercial EC-based rebar locator and a M...

The high neutral densities and short neutral mean free paths in the Alcator C-Mod divertor have provided a unique testing ground for our understanding of the role of neutrals in a tokamak. The high neutral pressures found in the C-Mod divertor can only be reproduced in models by including such collisional processes as ion-neutral and neutral-neutral collisions, neutral viscosity, as well as tak...
