Untethered small-scale robots can be potentially used in medical applications, such as minimally invasive surgeries and targeted drug delivery. This article introduces a new localization method using electrical impedance tomography, which is an emerging imaging technique, to dynamically track robots. The proposed approach provides the conductivity distribution within robot workspace from set of...

PURPOSE To realistically map the electric fields of biological tissues using a diffusion tensor magnetic resonance electrical impedance tomography (DT-MREIT) method to estimate tissue response during electrical stimulation. METHODS Imaging experiments were performed using chunks of bovine muscle. Two silver wire electrodes were positioned inside the muscle tissue for electrical stimulation. E...

The multifrequency electrical impedance tomography is considered in order to image a conductivity inclusion inside a homogeneous background medium by injecting one current. An original spectral decomposition of the solution of the forward conductivity problem is used to retrieve the Cauchy data corresponding to the extreme case of perfect conductor. Using results based on the unique continuatio...

Knowledge of permafrost structure, with accumulations free natural gas and hydrates, is indispensable for coping spontaneous emission other problems related to exploration production drilling in Arctic petroleum provinces. The existing geophysical methods have different potentialities imaging the base geometry, vertical fluid conduits (permeable zones), taliks, pockets, hydrate continental area...

in this paper, geographical information system (gis) is used as a support system for decision making in order to provide the map of high potential areas for the construction of greenhouses benefited from geothermal energy. the goal is to perform a geothermal energy resource assessment in eastern azerbaijan province as a base for further studies to achieve sustainable development objectives in t...

the objective of this research is to represent applicability of surface nuclear magnetic resonance (snmr) in aquifer characterization, based on snmr and electrical resistivity tomography data. snmr is the only geophysical method that directly detects water. two important parameters, porosity and permeability are available through inversion of initial amplitude and decay time constant versus pul...

neurolymphomatosis is a rare manifestation of non-hodgkin lymphoma characterized by infiltration of peripheral nerves, nerve roots, plexus and cranial nerves by malignant lymphocytes. this report presents positron emission tomography/computed tomography (pet/ct)imaging with 2-deoxy-2-18f-fluoro-d-glucose (18f-fdg) in 3 cases of non-hodgkin lymphoma with nerve infiltration, including one newly d...
