Patent number: 8090178Abstract: A medical imaging system is used to recognize an internal structure from a three-dimensional image. The image includes image sub-volumes. An image sub-volume is selected using a non-linear search pattern. The selected image sub-volume is analyzed for the presence of the internal structure. The steps of selecting an image sub-volume using the non-linear search pattern and analyzing the selected sub-volume for the presence of the internal structure are repeated until the internal structure is found in an image sub-volume. Bounds of the internal structure are identified based on the location of the image sub-volume within which the internal structure is found.Type: GrantFiled: March 30, 2007Date of Patent: January 3, 2012Assignee: Siemens Medical Solutions USA, Inc.Inventors: Dinesh Mysore Siddu, Mausumi Acharyya, Jonathan Stoeckel

Patent number: 7822240Abstract: The invention concerns an image processing device, including an input for receiving a time series of data sets representing comparable volume digital images, each data having a position component and an intensity component, pre-processing means for modifying the data sets so as to obtain images updated in position and intensity, and comparative processing means for examining sets of time series of image elements and to detect therein signs of variations. The processing means include a modeling function for adjusting a parametric model separately on some of the sets of time series of image elements, to obtain pairs of data (image element, time) and a function for statistical analysis of said pairs of data to isolate the pairs of data representing a significant variation.Type: GrantFiled: October 4, 2002Date of Patent: October 26, 2010Assignee: Inria Institut National de Recherche en Informatique et en AutomatiqueInventors: Nicholas Ayache, Grégoire Malandain, David Rey, Jonathan Stoeckel

Publication number: 20100135562Abstract: Described herein is a technology for supporting an efficient workflow. In one implementation, a computer system receives at least one image of a subject and at least one corresponding image finding (302). The image finding identifies one or more regions-of-interest in a subject area of the image. The computer system generates enhanced annotations based on the image finding (306), overlays the enhanced annotations on the image (310) and displays (312) the resulting image to facilitate image assessment by a skilled user.Type: ApplicationFiled: November 24, 2009Publication date: June 3, 2010Applicant: Siemens Computer Aided Diagnosis Ltd.Inventors: Michael Greenberg, Isaao Leichter, Jonathan STOECKEL

Publication number: 20100138240Abstract: Computer assisted detection (CAD) is made accessible to more medical offices. The CAD is provided as a service. Customers gain access to CAD service through a computer network but without the purchase of expensive software and/or hardware. The customers use software for extracting needed patient data to use the CAD service. The CAD service provider uses a server farm or third party server facilities, allowing growth without as substantial upfront costs. The CAD service provider collects patient data by providing the service. The aggregated patient data allows training of different or improved CAD algorithms. The service also identifies suspect data, such as associated with incorrect imaging settings, and provides help to the customers.Type: ApplicationFiled: November 23, 2009Publication date: June 3, 2010Inventors: David Leib, Jonathan Stoeckel

Patent number: 7684602Abstract: A method of visualizing an object in an image includes presenting an image, selecting a point in an object of interest in said image, estimating a gradient of the image in a region about the selected point, calculating a structure tensor from the image gradient, analyzing said structure tensor to determine a main orientation of said object of interest, and presenting a visualization of said object of interest based on the main orientation of the object. Various techniques can be used to increase the robustness of the gradient estimation with respect to noise, and to enhance the visualization of the object-of-interest presented to a user.Type: GrantFiled: April 11, 2005Date of Patent: March 23, 2010Assignee: Siemens Medical Solutions USA, Inc.Inventors: Pascal Cathier, Jonathan Stoeckel

Patent number: 7634120Abstract: We propose using different classifiers based on the spatial location of the object. The intuitive idea behind this approach is that several classifiers may learn local concepts better than a “universal” classifier that covers the whole feature space. The use of local classifiers ensures that the objects of a particular class have a higher degree of resemblance within that particular class. The use of local classifiers also results in memory, storage and performance improvements, especially when the classifier is kernel-based. As used herein, the term “kernel-based classifier” refers to a classifier where a mapping function (i.e., the kernel) has been used to map the original training data to a higher dimensional space where the classification task may be easier.Type: GrantFiled: August 10, 2004Date of Patent: December 15, 2009Assignee: Siemens Medical Solutions USA, Inc.Inventors: Arun Krishnan, Glenn Fung, Jonathan Stoeckel
