Publication number: 20150025358Abstract: A stand-alone MR or hybrid PET-MR imaging system incorporating a surface stationary RF coil structure is disclosed. The imaging system includes a support assembly comprising a cradle to accommodate a subject and a bridge to receive the cradle and provide for translation therealong to enable an acquisition of imaging data. An RF coil structure is positioned between the bridge and the cradle, and includes a base portion, a cover portion, and an array of RF coil elements positioned on the cover portion. The cover portion includes contoured features that enable placement of RF coil elements in proximity to a subject and to provide a constant and uniform gap between the RF elements and the cradle. The RF coil structure also includes structural elements that support the cradle when rolling over the array of RF coil elements without deforming the RF coil elements.Type: ApplicationFiled: July 17, 2013Publication date: January 22, 2015Inventors: Edward Emaci, Michael James Calloway

Patent number: 8027433Abstract: An x-ray imaging system includes a detector positioned to receive x-rays, and an x-ray tube coupled to a mount structure. The x-ray tube is configured to generate x-rays toward the detector and includes a target, a cathode cup, an emitter attached to the cathode cup and configured to emit a beam of electrons toward the target, the emitter having a length and a width, and a one-dimensional grid positioned between the emitter and the target and attached to the cathode cup at one or more attachment points. The one-dimensional grid includes a plurality of rungs that each extend in a direction of the width of the emitter, and the plurality of rungs are configured to expand and contract relative to the one or more attachment points without substantial distortion with respect to the emitter.Type: GrantFiled: July 29, 2009Date of Patent: September 27, 2011Assignee: General Electric CompanyInventors: Yun Zou, Carey Shawn Rogers, Sergio Lemaitre, Mark Alan Frontera, Edward Emaci, Vance Robinson

Patent number: 7519157Abstract: Systems, methods and apparatus are provided through which in some embodiments, a wrap-around capture device of an X-ray collimator frame limits movement of an X-ray tube mounting bracket away from the X-ray collimator. In some embodiments, a C-shaped passive capture device is attached or mounted on the wrap-around capture device, having a portion that is positioned in between the wrap-around capture device and the X-ray collimator frame, which further limits movement of the X-ray tube mounting bracket.Type: GrantFiled: July 23, 2005Date of Patent: April 14, 2009Assignee: General Electric CompanyInventors: Ron Kent Hockersmith, Edward Emaci, James Lorne Dodge, Eric Matthew Plate

Patent number: 7450690Abstract: An x-ray tube assembly is provided comprising a tube casing assembly including a plurality of vertical mount posts. An insulator plate is mounted to the plurality of vertical mount posts such that the insulator plate can translate vertically on the posts. A cathode assembly is mounted to the insulator plate and generates both an eccentric moment and a vertical expansion in response to a cathode power load. A semi-compressible element is positioned between at least one of the vertical mount posts and the insulator plate. The semi-compressible element becomes incompressible at a cathode power threshold such that the vertical expansion is translated into a correction moment countering the eccentric moment.Type: GrantFiled: July 8, 2005Date of Patent: November 11, 2008Assignee: General Electric CompanyInventors: Wayne Frederick Block, Edward Emaci, Sergio Lemaitre, Ron Kent Hockersmith

Publication number: 20080257939Abstract: A method is disclosed for brazing components in a structure using a gap setting surface and brazing foil as brazing filler between the parts in order to form uniform joints having optimal dimensions, shape and strength. The components are assembled in an unconstrained stack, and a controlled load is applied to the top of the stack. The stack is then heated to a temperature at which the brazing foil melts and reacts with the components to form the joints. The stack is cooled resulting in a brazed structure having the desired dimension.Type: ApplicationFiled: April 18, 2007Publication date: October 23, 2008Inventors: Edward Emaci, Kent Shue

Publication number: 20020171556Abstract: A sensor detects skewed adjacent movable components. The sensor may be used to detect harmful skews of aircraft control surfaces, such as slats or flaps on aircraft wings, which may be caused by an actuator disconnection from the surface it drives. Harmful skew, which is a relative asymmetrical motion of control surfaces beyond a predetermined limit, is detected by the sensor, but the relatively smaller harmless skew caused by normal flight is ignored. The sensor comprises first and second arms connected to a common base that may be attached to a first control surface. A constraining means such as a mechanical fuse holds the arms together while a separating means such as a spring exerts a separating force on the arms when the fuse breaks. A switching means is integral to the two arms. A striker pin on a second control surface strikes the first or second sensor arm when the relative motion between the control surfaces exceeds a certain predetermined limit.Type: ApplicationFiled: May 21, 2001Publication date: November 21, 2002Inventors: Edward Emaci, Scott Wilkinson, William Leden
