Patent number: 9958522Abstract: A method for determining the spatial distribution of magnetic resonance signals from at least one of N subvolumes predefines a reception encoding scheme and determines unique spatial encoding for at least one of the subvolumes but not for the entire volume under examination (UV). A transmission encoding scheme is also defined, wherein encoding is effected via the amplitude and/or phase of the transverse magnetization. The temporal amplitude and phase profile of the RF pulses is then calculated and each reception encoding step is carried out I times with variations according to the I transmission encoding steps in the transmission encoding scheme. The method makes it possible to largely restrict the spatially resolving MR signal encoding and image reconstruction to subvolumes of the object under examination without the achievable image quality sensitively depending on imperfections in the MR apparatus.Type: GrantFiled: April 18, 2012Date of Patent: May 1, 2018Assignee: Bruker BioSpin MRI GmbHInventors: Wolfgang Ruhm, Johannes Schneider, Peter Ullmann

Patent number: 9958563Abstract: A solid scintillator member is provided in the internal space of a container. The scintillator member is an aggregate of a plurality of pellets. The internal space also confines a gas produced through the vaporization of a liquid sample containing a radioactive substance. When radiation emitted from a plurality of particles within the gas reaches the scintillator member, light is generated. That light is detected by a pair of photomultipliers. A plurality of particles may be produced outside of the container and introduced into the container.Type: GrantFiled: July 17, 2015Date of Patent: May 1, 2018Assignees: OCHANOMZU UNIVERSITY, Hitachi, Ltd.Inventors: Etsuko Furuta, Yuka Kato, Kiyoshi Ogiwara

Patent number: 9958566Abstract: An airborne ElectroMagnetic (EM) survey system wherein the system includes; first, a series of transmitter coils, which induce a primary (EM) field into the earth resulting in a secondary EM field being created in any sub-surface electrically conductive bodies; and second, a set of three orthogonal receiver coils which detect the secondary EM field. Multiple transmitter coils through which an electric current is pumped, form part of the structural, aluminum framework of a multi-rotor drone. The receiver sensor may be an EM induction sensor, comprised of multi-turn, copper windings, mounted inside an aerodynamic bird and separated by non-conductive sphalerite, which acts as an electrical insulator to limit self-induction and capacitance. Additionally a lighter-than-air balloon may be used to add vertical lift and increase a pendulum effect.Type: GrantFiled: November 5, 2015Date of Patent: May 1, 2018Inventor: Isaac Max Porterfield

Patent number: 9958567Abstract: In one example of rotational ranging in a wellbore in which a wellbore component having an axis of rotation is disposed, a wellbore ranging sensor is disposed on a circumferential area surrounding the axis of rotation. The sensor is moved on the circumferential area to multiple distinct sensing positions. At each sensing position, a magnetic field from another wellbore that is apart from the wellbore is measured resulting in multiple magnetic field measurements at the multiple distinct sensing positions. The multiple magnetic field measurements are provided to determine a position of the wellbore relative to the other wellbore using at least a subset of the multiple magnetic field measurements.Type: GrantFiled: July 31, 2013Date of Patent: May 1, 2018Assignee: Halliburton Energy Services, Inc.Inventors: Christopher A. Golla, Randal T. Beste, Svetozar Simeonov, Burkay Donderici, Luis E. San Martin
