US Patent:

8073215, Dec 6, 2011
Filed:

Aug 6, 2008
Appl. No.:

12/186815
Inventors:

Xiaoguang Lu - Plainsboro NJ, US
Bogdan Georgescu - Plainsboro NJ, US
Yefeng Zheng - Dayton NJ, US
Joanne Otsuki - Oakland CA, US
Dorin Comaniciu - Princeton Junction NJ, US
Assignee:

Siemens Medical Solutions USA, Inc. - Malvern PA
International Classification:

G06K 9/00
US Classification:

382128
Abstract:

A plane position for a standard view is detected from three-dimensional echocardiographic data. The position of the plane within the volume is defined by translation, orientation (rotation), and/or scale. Possible positions are detected and other possible positions are ruled out. The classification of the possible positions occurs sequentially by translation, then orientation, and then scale. The sequential process may limit calculations required to identify the plane position for a desired view.

Appl. No.:

12/210419
Inventors:

International Classification:

A61B 8/00
A61B 8/08
US Classification:

600450, 600437, 600441, 600443, 600453, 600454, 600455, 600457, 600463
Abstract:

A view represented by echocardiographic data is classified. A probabilistic boosting network is used to classify the view. The probabilistic boosting network may include multiple levels where each level has a multi-class local structure classifier and a plurality of local-structure detectors corresponding to the respective multiple classes. In each level, the local structure is classified as a particular view and then the local structure is detected to determine whether the currently selected local structure corresponds to the class. The view classification may be used to determine gate locations, such as a gate for spectral Doppler analysis.

Filed:

Appl. No.:

12/214339

Assignee:

Siemens Corporation - Iselin NJ
International Classification:

G06K 17/00
US Classification:

382128
Abstract:

A method and system for detection of deformable structures in medical images is disclosed. Deformable structures can represent blood flow patterns in images such as Doppler echocardiograms. A probabilistic, hierarchical, and discriminant framework is used to detect such deformable structures. This framework integrates evidence from different primitive levels via a progressive detector hierarchy, including a series of discriminant classifiers. A target deformable structure is parameterized by a multi-dimensional parameter, and primitives or partial parameterizations of the parameter are determined. An input image is received, and a series of primitives are sequentially detected using the progressive detector hierarchy, in which each detector or classifier detects a corresponding primitive. The final detector detects configuration candidates for the deformable structure.

Filed:

Jul 10, 2007
Appl. No.:

11/775538
Inventors:

Shaohua Kevin Zhou - Plainsboro NJ, US
Joanne Otsuki - Oakland CA, US
Dorin Comaniciu - Princeton Junction NJ, US
Bogdan Georgescu - Plainsboro NJ, US

Assignee:

Siemens Medical Solutions USA, Inc. - Malvern PA
International Classification:

G06K 9/00
US Classification:

382128, 382224
Abstract:

A method for view classification includes providing a frame of an object of interest, detecting a region of interest within the object of interest for each of a plurality of detectors (e. g. , binary classifiers), wherein each binary classifier corresponds to a different view, performing a global view classification using a multiview classifier for each view, outputting a classification for each view, fusing outputs of the multiview classifiers, and determining and outputting a classification of the frame based on a fused output of the multiview classifiers.

Filed:

Oct 25, 1996
Appl. No.:

8/739112
Inventors:

Laurence S. McCabe - Sunnyvale CA
Donald R. Langdon - Moutain View CA

Assignee:

Acuson Corporation - Mountain View CA
International Classification:

A61B 506
US Classification:

600454
Abstract:

A method for interactively detecting a maximum velocity from acquired echo signals in an ultrasound system is provided. A processor with maximum velocity code is provided. The code has a variable. A user input provides a value for the variable while the ultrasound system is in a maximum velocity mode. The ultrasound system is operated in a maximum velocity mode. The echo signals are processed to determine said maximum velocity, and the processing is adjusted while remaining in said maximum velocity mode. During CINE playback, delimeters are generated for adjusting the time period of parameter calculation.
