Patent number: 8675929Abstract: Certain embodiments of the present invention provide a system and method for synchronized viewing of a plurality of images of an object. Corresponding landmarks of an object are synchronized between a first image set and a second image set. In an embodiment, the landmarks are folds of a human colon and the first image set and second images sets are computerized tomography scans, at least one image set being a prone scan of a portion of anatomy and at least one image set being a supine scan of a portion of the anatomy. An indicator for at least a first location in a first image set is displayed. The location of a second location in a second image set of an object is determined, wherein the second location corresponds to the first location of the object. The second location in the second image set is displayed.Type: GrantFiled: August 9, 2007Date of Patent: March 18, 2014Assignee: GE Medical Systems Global Technology Co., LLCInventors: Saad Ahmed Sirohey, Gopal B.

Patent number: 8165358Abstract: A system and method for displaying a set of data with a virtually dissected anatomical structure. In an embodiment, the anatomical structure is a colon and various attributes of the colonic lumen are assigned a color. In an embodiment, a virtual dissection of the colon is created by mapping a three-dimensional data set to a two dimensional data set. A plurality of display index values are computed which correspond to the three-dimensional data set. Various colors are assigned to specific display index values. The three-dimensional display index values are mapped to a two-dimensional set of display index values. As directed by a user, various color cues may be displayed with the virtually dissected lumen to provide color highlights to various aspects of the colon, such as highlighting shape, fluid, or fecal presence.Type: GrantFiled: January 12, 2004Date of Patent: April 24, 2012Assignee: GE Medical Systems Global Technology Co., LLCInventors: Saad Ahmed Sirohey, Gopal B.

Patent number: 8036490Abstract: To measure the dimensions of a tubular vessel, it is planned to plot a set of wall lines on the surface of the vessels. Then, the lengths of these wall lines are measured between a starting section and an arrival section. The plotting of the wall lines starts from a central line of the vessel divided into segments. For each central line segment, a wall line segment is defined on the wall by intersection of a plane containing this central line segment and intersecting this wall. Other wall line segments are distributed all around and all along the wall. Then, the lengths are measured.Type: GrantFiled: November 15, 2007Date of Patent: October 11, 2011Assignee: General Electric CompanyInventors: Renaud Capolunghi, Pascal Pineau, Laurent Launay

Patent number: 7565000Abstract: A system and method for segmenting and editing anatomical objects from medical images is disclosed. The system may be a medical diagnostic imaging system. A computer unit may execute computer software for segmenting anatomical objects from medical images. The computer software may extract an anatomical object from planar curves. The computer software may extract an anatomical object by computing the centerline of the anatomical object. A set of reformatted images may then be derived based on the centerline of the object. A user may then provide input in the form of user drawn contours on a plurality of reformatted images. In an embodiment the reformatted images may include a reformatted longitudinal view, a curved reformatted view, or a lumen view. The user drawn contours may correspond to the boundaries of the anatomical object to be segmented. The anatomical object may then be extracted based on the user drawn contours.Type: GrantFiled: November 23, 2005Date of Patent: July 21, 2009Assignee: General Electric CompanyInventors: Renaud Capolunghi, Laurent Launay, Jerome Knoplioch, Pál Csongor Sprencz

Patent number: 7274811Abstract: Certain embodiments of the present invention provide a system and method for automatically synchronizing multiple images. Multiple image sets of a single object are converted into a one dimensional data stream used to synchronize multiple image sets. A common reference point is located in the image sets. Various landmarks of the object are also located in the image sets. Corresponding landmarks among the image sets are noted. Distances from landmarks to the reference point and distances between landmarks are determined. Locations of the landmarks in relation to each other and in relation to the reference point are used to locate landmarks in another image set that correspond to landmarks in a selected image set. A first location in an image set may be identified using a first indicator. A second indicator corresponding to the location of the first indicator may then be determined in another image set.Type: GrantFiled: October 31, 2003Date of Patent: September 25, 2007Assignee: GE Medical Systems Global Technology Company, LLCInventors: Saad Ahmed Sirohey, Gopal B.
