Patent number: 9349197Abstract: The left ventricle epicardium is estimated in medical diagnostic imaging. C-arm x-ray data is used to detect an endocardium at different phases. The detected endocardium at the different phases is compared to sample endocardiums at different phases. The sample endocardiums have corresponding sample epicardiums. The transformation between the most similar sample endocardium or endocardiums over time and the detected endocardium over time is applied to the corresponding sample epicardium or epicardiums. The transformed sample epicardium over time is the estimated epicardium over time for the C-arm x-ray data.Type: GrantFiled: June 26, 2012Date of Patent: May 24, 2016Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Mingqing Chen, Yefeng Zheng, Kerstin Mueller, Christopher Rohkohl, Günter Lauritsch, Jan Boese, Gareth Funka-Lea, Dorin Comaniciu

Patent number: 9240071Abstract: A 3D result image of an object is reconstructed from a set of X-ray two-dimensional projections of the object. A 3D reference image of the object is reconstructed by employing a compressed sensing technique based on at least some of the 2D projections at a reference motion state of the object. By employing an algebraic and/or analytic reconstruction technique, 3D intermediate images are reconstructed for various motion states of the object. The 3D intermediate images are registered with the 3D reference image to obtain spatial transformations for the various motion states of the object. Based on the spatial transformations, the 3D intermediate images are transformed to a joint phase and combined to obtain the 3D result image.Type: GrantFiled: August 5, 2013Date of Patent: January 19, 2016Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Kerstin Mueller, Christopher Rohkohl, Günter Lauritsch, Chris Schwemmer

Patent number: 9147268Abstract: Background information is subtracted from projection data in medical diagnostic imaging. The background is removed using data acquired in a single rotational sweep of a C-arm. The removal may be by masking out a target, leaving the background, in the data as constructed into a volume. For subtraction, the masked background information is projected to a plane and subtracted from the data representing the plane.Type: GrantFiled: June 26, 2012Date of Patent: September 29, 2015Assignee: Siemens AktiengesellschaftInventors: Mingqing Chen, Yefeng Zheng, Kerstin Mueller, Christopher Rohkohl, Günter Lauritsch, Jan Boese, Gareth Funka-Lea, Dorin Comaniciu
