Patent number: 9655592Abstract: A method for rendering an image from ultrasound image data includes dividing the ultrasound image data into at least a first group of voxels and a second group of voxels, based on comparing voxel echo intensity to a threshold value. The method further includes processing the first group of voxels according to a first protocol and processing the second group of voxels according to a second protocol. The method further includes generating an image that includes both the first group of processed voxels and the second group of processed voxels to enhance realism of the rendered image.Type: GrantFiled: November 21, 2014Date of Patent: May 23, 2017Assignee: GENERAL ELECTRIC CORPORATIONInventors: Gerald Schroecker, Eduard Gröller, Alexey Karimov, Stefan Bruckner, Daniel Buckton

Patent number: 9390546Abstract: Methods and system for visualizing 3D ultrasound data are provided. One method includes obtaining image slices from a volumetric image data set and generating a ray profile using one or more rays through at least one of the image slices, wherein the one or more rays extend along a depth of the volumetric image data set. The method further includes identifying one or more seed points along the one or more rays and defining a clipping surface using the one or more seed points, wherein the clipping surface defines a rendering region within the volumetric image data set. The method also includes rendering a 3D image of the rendering region within the volumetric image data set.Type: GrantFiled: October 30, 2013Date of Patent: July 12, 2016Assignee: General Electric CompanyInventors: Daniel John Buckton, Gerald Schroecker, Andrej Varchola, Stefan Bruckner, Eduard Groeller, Johannes Novotny

Publication number: 20090002366Abstract: A method and a corresponding apparatus for volume rendering of medical data sets comprises a display (11) for displaying at least one slice view (12) of a medical data set (18) of an object, in particular a patient. A user selection unit (13, 14, 15) enables a user to select a position on a structure of interest (SOI) in the at least one displayed slice view (12), a volume rendering unit (16) for determines a volume rendering (17) of the structure of interest (SOI) based on one or more first parameters. The first parameters characterize the view of the displayed volume rendering (17, 31) of the structure of interest (SOI), the volume rendering (17, 31) of the structure of interest (SOI) being displayed on the display (11).Type: ApplicationFiled: June 6, 2008Publication date: January 1, 2009Applicant: AGFA HEALTHCARE N.V.Inventors: Armin Kanitsar, Peter Kohlmann, Stefan Bruckner, M.
