Patent number: 8885904Abstract: Systems and methods for landmark correction in Magnetic Resonance Imaging (MRI) are provided. One method includes acquiring at least one calibration image or at least one localizer image of an object, identifying in the calibration or localizer images a region of the object as a reference point, wherein the reference point defines a landmark position. The method further includes determining an offset between an initial landmark position and the identified landmark position. The method also includes using the determined offset for MRI.Type: GrantFiled: April 19, 2012Date of Patent: November 11, 2014Assignee: General Electric CompanyInventors: Robert David Darrow, Thomas Foo, Maggie Fung, Vivek Prabhakar Vaidya, Xiaodong Tao

Patent number: 8110382Abstract: A process is provided for producing glycolic acid from formaldehyde and hydrogen cyanide. More specifically, heat-treated formaldehyde and hydrogen cyanide are reacted to produce glycolonitrile having low concentrations of impurities. The glycolonitrile is subsequently converted to an aqueous solution of ammonium glycolate using an enzyme catalyst having nitrilase activity derived from Acidovorax facilis 72W (ATCC 57746). Glycolic acid is recovered in the form of the acid or salt from the aqueous ammonium glycolate solution using a variety of methods described herein.Type: GrantFiled: August 12, 2008Date of Patent: February 7, 2012Assignee: E. I. du Pont de Nemours and CompanyInventors: Robert DiCosimo, Anna Panova, Jeffery Scott Thompson, Robert D. Fallon, F. Glenn Gallagher, Thomas Foo, Xu Li, George C. Fox, Joseph J. Zaher, Mark S.
