Bedside monitoring plays an important role in the treatment of lung cancer. As a mostly used technique, X-ray computed tomography cannot provide medical surveillance for patients suffering from cancer real-time. In comparison, technique electrical impedance (EIT) has potential to solve issue by visualizing human respiratory system; however, most cases, its spatial resolution is too low locate real pulmonary lesions. One feasible method improve image quality incorporate <italic...
As an advanced measurement technique of non-radiant, non-intrusive, rapid response, and low cost, the electrical tomography (ET) has developed rapidly in recent decades. The ET imaging algorithm plays important role process. Linear back projection (LBP) is most used due to its advantages dynamic process, real-time easy realization. But LBP spatial resolution natural 'soft field' effect 'ill-posed solution' problems; thus applicable ranges are greatly limited. In this paper, original data...
Abstract In air/oil lubrication systems, the flow parameters, e.g., pattern, liquid film thickness, and rate, are of great importance to transportation efficiency. most cases, on-going two-phase is annular with oil moving along tube wall air travelling at high speed in center. This usually results formation a thin film, thickness which key parameter determining efficiency system. As varies dynamically, there actually no applicable method for non-intrusive test. this paper, use electrical...
Adhesion energies of Cu-low k dielectric interfaces, measured with the technique four-point bending, show a correlation to chemical mechanical polish results. A limit 5 J/m/sup 2/ is established, below which thin film delamination and cracking are observed. In general, spin-on polymer dielectrics exhibit better adhesion barrier films than carbon-doped oxide dielectrics. PVD barriers low CVD barriers. Surface treatments before deposition found strongly modulate adhesion.
In water conservation projects, reservoirs play a key role in controlling and regulating floods. recent years, extreme rainfall events have occurred more frequently. Urban danger under happen occasionally. The breaching of urban seriously threatens the lives property population downstream. A lack clarity regarding characterization flooding response remains owing to reservoir overtopping different conditions. This study used observed data from heavy event Zhengzhou on July 20, 2021, with...
The elastic modulus and hardness of low k dielectric films rapidly decrease as porosity increases. By contrast, interfacial adhesion is relatively insensitive to porosity. Adhesion energy values measured by the four-point bend method are similar for porous non-porous films. Additionally, much stronger polymer than organosiloxane films, regardless E-beam treatments significantly improve sacrificing only a slight increase in constant. Solid-state NMR pore size measurements indicate that...
Early lung cancer identification is a very promising way to prevent and cure cancer. The current method based on the X-ray computed tomography difficultly identify early cancer, while electrical resistance (ERT) technique has potential overcome problem by visualizing human respiratory system. original ERT system poor quality of reconstructed images. One feasible improve image incorporate prior information into ET imaging process. In this paper, we first extract from group patient's CT images...
Electrical impedance tomography (EIT) is a visual imaging technique for obtaining the conductivity and permittivity distributions in domain of interest. As an advanced technique, EIT has potential to be valuable tool continuously bedside monitoring pulmonary function. The applications any three-dimensional (3 D) field are very limited 3 D effects, i.e. distribution electric spreads far beyond electrode plane. effects can result measurement errors image distortion. An important way overcome...

Electrical impedance tomography (EIT) aims to estimate the electrical properties at interior of an object from current-voltage measurements on its boundary. It has been widely investigated due advantages low cost, non-radiation, non-invasiveness, and high speed. Image reconstruction EIT is a nonlinear ill-posed inverse problem. Therefore, regularization techniques like Tikhonov are used solve A sparse based L1 norm exhibits superiority in preserving boundary information sharp changes or...
Electrical impedance tomography (EIT) is a noninvasive imaging technology that widely used in industrial and medical applications. The reconstruction methods are ill-posed sensitive to the scale of perturbations prior assumptions, so differential mostly practice. Absolute promising but has always been challenge practical One obstacles determine reference measurement frame from uniform distributed domain. In this article, we develop estimation technique for homogeneous conductivity...
The possibility to design wearable devices based on electrical impedance tomography (EIT) has recently given a boost this technology. However, the coverage of sensor array will vary with size difference measured object, resulting in an incomplete measurement set. If set is directly invested solution inverse problem, imaging quality be significantly degraded. In case, it necessary take measures reduce impact missing data reconstruction. article, new method (MinR-DFF) proposed which provides...
In the application of oil-air lubrication system, electrical capacitance tomography (ECT) provides a promising way for monitoring oil film in pipelines by reconstructing cross sectional distributions real time. While case small diameter pipe and thin film, thickness is hard to be observed visually since interface air not obvious reconstructed images. And existence artifacts reconstructions has seriously influenced effectiveness image segmentation techniques such as level set method. Besides,...
