20160097664 | APPARATUS AND METHOD FOR MEASURING VELOCITY AND COMPOSITION OF MATERIAL IN AND ADJACENT TO A BOREHOLE - This disclosure provides systems, methods, and apparatus for measuring flow in and around a borehole of an earth formation. A flow measurement device can include a magnet configured to generate a static solenoidal magnetic field with a field intensity that decreases in strength peripherally from the magnet, an electromagnet disposed around the magnet and configured to generate a time varying solenoidal magnetic field, and a radio frequency (RF) coil disposed around the magnet and configured to generate an RF magnetic field transverse to the static solenoidal magnetic field. The flow measurement device can calculate a flow velocity in and around the flow measurement device based upon a signal received by the RF coil. | 04-07-2016 |
20150247906 | APPARATUS AND METHOD FOR MAGNETIC RESONANCE MEASUREMENT AND MAPPING OF ELECTRICAL IMPEDANCE, COMPLEX PERMITTIVITY AND COMPLEX CONDUCTIVITY AS APPLIED TO DETECTION AND EVALUATION OF SAMPLE PATHOLOGY - A method of measurement of or mapping the distribution of complex permittivity, complex conductivity, complex impedance, or electric loss angle during magnetic resonance imaging or analysis. The method includes applying a time-varying electric field of a Faraday shield to a sample and cross-correlating the line spectrum signal so produced with the voltage applied to the Faraday shield in a detection circuit. The method permits non-contrast magnetic resonance screening for breast cancer in vivo and/or continuous measurement of electrical characteristics of materials at variable frequencies in vitro. A system of detecting and evaluating sample pathology includes a Faraday shield device that includes parallel electrodes oriented orthogonal to the static magnetic field of a MRI device to produce a time varying electric field. A detector is coupled to the MRI device to detect at least one of a complex permittivity, a complex conductivity, and an electrical impedance of the sample. | 09-03-2015 |
20150137809 | APPARATUS AND METHOD FOR MAPPING AND MEASUREMENT OF SPATIALLY AND TEMPORALLY DISTRIBUTED INDUCED SMALL PHASE DEVIATIONS IN MAGNETIC RESONANCE UTILIZING DECONVOLUTION - Phase variations of the transverse magnetization in magnetic resonance induced by superimposed physical phenomenae or by intrinsic deviations of the main magnetic B0 field are separated from Feature Space set by demodulation and deconvolution, either by electrical circuits or by equivalent computational methods, permitting mapping and measurement of these induced phase variations independent of Feature Space. | 05-21-2015 |
