Patent number: 8803910Abstract: A two-dimensional contouring tool that allows a user to maintain a minimum distance away (in 3D) from other structures. The contouring tool allows the user to rapidly define a series of contours that conform to the shape of one or more existing contours (or targets) with user-specified margin limits between the new contour and the existing contours (or targets).Type: GrantFiled: August 28, 2009Date of Patent: August 12, 2014Assignee: Tomotherapy IncorporatedInventors: Kevin S. Menningen, David T. Gering, Kenneth J. Ruchala

Patent number: 8577115Abstract: A system and method of identifying anatomical structures in a patient. The method includes the acts of acquiring an image of the patient, the image including a set of image elements; segmenting the image to categorize each image elements according to its substance; computing the probability that the categorization of each image element is correct; resegmenting the image starting with image elements that have a high probability and progressing to image elements with lower probabilities; aligning at least one of the image elements with an anatomical atlas; and fitting the anatomical atlas to the segmented image.Type: GrantFiled: March 4, 2009Date of Patent: November 5, 2013Assignee: Tomotherapy IncorporatedInventors: David T. Gering, Kenneth J. Ruchala

Patent number: 8125484Abstract: A graphical user interface and method allows a user to interactively select an arterial input function. An anatomical image and time-course data corresponding to a selected region of interest are displayed simultaneously. The time-course data is displayed as an array of graphs, annotated with best-fit curves and parameters derived from fitting the time-course data. The region displayed in the graphs may be updated by panning and zooming with a mouse in the image. Time-course data corresponding to a graph is selected for use in deriving an arterial input function. The arterial input function is used to calculate maps of hemodynamic parameters.Type: GrantFiled: November 10, 2006Date of Patent: February 28, 2012Assignee: General Electric CompanyInventor: David T. Gering

Patent number: 7831077Abstract: A method for generating an image of a region of interest of a subject includes obtaining a set of magnetic resonance (MR) data for the region of interest. In addition, photographic data for at least one surface of the region of interest is obtained, for example, from a database or by using a camera for photographing the region of interest. An image is generated by using the set of MR data to generate a depiction of at least one structure of the region of interest and by using the photographic data to generate a depiction of at least one surface of the region of interest.Type: GrantFiled: March 7, 2007Date of Patent: November 9, 2010Assignee: General Electric Co.Inventor: David T. Gering

Patent number: 7693349Abstract: System and method for incorporating user input on the fly during an otherwise automatic registration process. During rigid registration, user input adjusts the current computed pose or transformation that relates the two images being aligned. During warping, user input adjusts the flow field locally, and is gradually smoothed into the surrounding flow field. During multi-scale registration where images are first aligned at a course resolution, and subsequently at progressively finer resolutions, user input is applied at the current scale. User input is detected during the automated process either by interrupts or polling. Between user inputs the registration results are re-rendered.Type: GrantFiled: August 15, 2006Date of Patent: April 6, 2010Assignee: General Electric CompanyInventor: David T Gering

Patent number: 7643662Abstract: Systems and methods are provided for accessing three dimensional representation of an anatomical surface and flattening the anatomical surface so as to produce a two dimensional representation of an anatomical surface. The two dimensional surface can be augmented with computed properties such as thickness, curvature, thickness and curvature, or user defined properties. The rendered two dimensional representation of an anatomical surface can be interacted by user so as to deriving quantitative measurements such as diameter, area, volume, and number of voxels.Type: GrantFiled: August 15, 2006Date of Patent: January 5, 2010Assignee: General Electric CompanyInventor: David T Gering

Patent number: 5761376Abstract: A method and system are provided for controlling a motor to rapidly accelerate and synchronize with an external synchronization pulse. First, the motor is accelerated to only half of the desired speed. At this point, the phase error with the sync pulse is calculated, and the motor continues "cruising" at half speed until the phase discrepancy diminishes. Then the motor rises to the full desired speed at the optimal time such that it is in phase with the sync pulse just as it reaches full speed. The acceleration is performed at a constant, yet slow enough, rate to receive at least three speed feedbacks. Then the instantaneous speed can be accurately measured and the next (and final) speed command during acceleration is interpolated between the ideal command for rising and the ideal command for cruising at the desired speed.Type: GrantFiled: May 5, 1997Date of Patent: June 2, 1998Assignee: General Electric CompanyInventor: David T.
