Publication number: 20170197279Abstract: Apparatus and methods are disclosed for performing laser ablation. In an example arrangement a spatial light modulator (54) is used to modulate a pulsed laser beam from a solid state laser (52). A two-stage de-magnification process (58, 62) is used to allow radiation intensity to be kept relatively low at the spatial light modulator (54) while allowing access to feedback sensors (64) in an intermediate imaging plane.Type: ApplicationFiled: August 19, 2015Publication date: July 13, 2017Applicant: M-SOLV LTD.Inventors: David Charles MILNE, Philip Thomas RUMSBY, David Thomas Edmund MYLES

Publication number: 20160166205Abstract: This invention relates to a system that adaptively compensates for subject motion in real-time in an imaging system. An object orientation marker (30), preferably a retro-grate reflector (RGR), is placed on the head or other body organ of interest of a patient (P) during a scan, such as an MRI scan. The marker (30) makes it possible to measure the six degrees of freedom (x, y, and z-translations, and pitch, yaw, and roll), or “pose”, required to track motion of the organ of interest. A detector, preferably a camera (40), observes the marker (30) and continuously extracts its pose. The pose from the camera (40) is sent to the scanner (120) via an RGR processing computer (50) and a scanner control and processing computer (100), allowing for continuous correction of scan planes and position (in real-time) for motion of the patient (P).Type: ApplicationFiled: August 17, 2015Publication date: June 16, 2016Inventors: Thomas Michael Ernst, Thomas Edmund Prieto, Brian Stewart Randall Armstrong

Publication number: 20150023468Abstract: A portable x-ray system includes a light weight x-ray head including an x-ray tube and a high voltage (HV) tank, wherein the HV tank comprises a compact voltage multiplier configured to receive a low voltage signal and generate a high voltage signal based on the received low voltage signal. Also, the portable x-ray system includes a carrying case comprising low voltage power electronics coupled to the light weight x-ray head through a low voltage cable, and configured to send the low voltage signal to the light weight x-ray head. In addition, the low voltage power electronics is distributed in a predefined space in the carrying case in such a way that a weight of the light weight x-ray head is counter weighed by a weight of the low voltage power electronics to stabilize the portable x-ray system when the light weight x-ray head is rotated in one or more directions.Type: ApplicationFiled: July 17, 2013Publication date: January 22, 2015Inventors: Yun Zou, Scott Stephen Zelakiewicz, Fengfeng Tao, Xi Zhang, Timothy Powers, Thomas Edmund Sjoberg, Marc Weasler, Denis Perrillat-Amede

Patent number: 8923484Abstract: A motion correction system and method for motion correction for an x-ray tube is presented. One embodiment of the motion correction system includes a sensing unit coupled to an x-ray tube to determine a distance with which an impingement location of an electron beam generated by the x-ray tube deviates from a determined location due to motion of the x-ray tube. The motion correction system further includes a control unit coupled to the sensing unit to generate a control signal corresponding to the distance with which the impingement location of the electron beam deviates. Also, the motion correction system includes a deflection unit coupled to the control unit to steer the electron beam to the determined location based on the generated control signal.Type: GrantFiled: August 31, 2012Date of Patent: December 30, 2014Assignee: General Electric CompanyInventors: Yun Zou, Scott Stephen Zelakiewicz, Floribertus P.

Patent number: 8771129Abstract: A limited slip differential assembly includes first and second output gears in constant meshed engagement with a pinion gear. Each of the gears is rotatably positioned within a carrier housing. The second output gear is axially moveable. A rotary to linear motion actuator includes a rotatable first member and a second member axially moveable in response to rotation of the first member. A primary clutch drivingly interconnects the second output gear and the first member of the actuator. The primary clutch includes an apply plate coupled to the second output gear such that an axial force acting on the second output gear during torque transmission through the differential assembly is transferred to the primary clutch via the apply plate. A secondary clutch drivingly interconnects the second output gear and the carrier housing. The second member of the actuator provides an apply force to the secondary clutch.Type: GrantFiled: January 16, 2013Date of Patent: July 8, 2014Assignee: Magna Powertrain of America, Inc.Inventor: Thomas Edmund Bradford, Jr.

Patent number: 8548636Abstract: Loads on an electric power system are configured with under-frequency relays in which the frequency setpoints and delay times for reclosure are uniformly distributed. If demand exceeds supply in the system, frequency will decrease. The decrease in frequency will actuate relays and reduce load to the point where demand will meet the available supply. After its engineered delay time, each relay will attempt to close contact and reestablish the load.Type: GrantFiled: September 25, 2009Date of Patent: October 1, 2013Assignee: Lawrence Livermore National Secuirty, LLC.Inventor: Thomas A.

Patent number: 8374411Abstract: This invention relates to a system that adaptively compensates for subject motion in real-time in an imaging system. An object orientation marker, preferably a retro-grate reflector (RGR), is placed on an organ of interest of a patient during a scan, such as an MRI scan. The marker allows measuring the six degrees of freedom or “pose” required to track motion of the organ of interest. A detector, preferably a camera, observes the marker and continuously extracts its pose. The pose from the camera is sent to the scanner via an RGR processing computer and a scanner control and processing computer, allowing for continuous correction of scan planes and position (in real-time) for motion of the patient. This invention also provides for internal calibration and for co-registration over time of the scanner's and tracking system's reference frames to compensate for drift and other inaccuracies that may arise over time.Type: GrantFiled: December 27, 2011Date of Patent: February 12, 2013Assignees: The Queen's Medical Center, The University of Hawaii, The Medical College of Wisconsin, Inc., UWM Research Foundation, Inc.Inventors: Thomas Michael Ernst, Thomas Edmund Prieto, Brian Stewart Randall Armstrong

Patent number: 8121361Abstract: Current MRI technologies require subjects to remain largely motionless for achieving high quality magnetic resonance (MR) scans, typically for 5-10 minutes at a time. However, lying absolutely still inside the tight MR imager (MRI) tunnel is a difficult task, especially for children, very sick patients, or the mentally ill. Even motion ranging less than 1 mm or 1 degree can corrupt a scan. This invention involves a system that adaptively compensates for subject motion in real-time. An object orientation marker, preferably a retro-grate reflector (RGR), is placed on a patients' head or other body organ of interest during MRI. The RGR makes it possible to measure the six degrees of freedom (x, y, and z-translations, and pitch, yaw, and roll), or “pose”, required to track the organ of interest. A camera-based tracking system observes the marker and continuously extracts its pose.Type: GrantFiled: May 18, 2007Date of Patent: February 21, 2012Assignees: The Queen's Medical Center, The University of Hawaii, The Medical College of Wisconsin, Inc., UWM Research Foundation, Inc.Inventors: Thomas Michael Ernst, Thomas Edmund Prieto, Brian Stewart Randall Armstrong
