  • Publication number: 20090112251
    Abstract: Embodiments of the present invention are directed to occluder devices and methods for treating various target sites, such as the gonadal vein. For example, an occluder device according to one embodiment includes a tubular structure having proximal and distal ends and a preset, expanded configuration. The tubular structure is configured to be constrained to a reduced configuration for delivery to the target site and to at least partially return to the preset, expanded configuration within the target site when unconstrained. The preset, expanded configuration includes a plurality of expanded volume members and articulating members arranged in a repeating pattern with each articulating member coupling a pair of expanded volume members. In addition, at least one expanded volume member has a cross-sectional dimension that is larger than a cross-sectional dimension of a respective articulating member and that is at least as large as a cross-sectional dimension of the target site.

  • Patent number: 7315304
    Abstract: Method and system for multiple volume exploration is disclosed. A first 3D volume is rendered in a first region. One or representations are displayed in a second region, where each representation signifies a stack of 2D images. A first stack represents one or more 2D images of cross sections of a certain orientation from the first 3D volume. Each of the other stacks includes one or more 2D images of cross sections of the same orientation from a 3D volume related to the first 3D volume.

  • Patent number: 7088850
    Abstract: Method and system for lesion detection is disclosed. A lesion is detected from each data set in the spatial domain based on an organ intensity subtracted (OIST) image. In the temporal domain, the lesion is detected based on a maximum frequency-magnitude difference (MFMD) map across a plurality of data sets. The detection result from the spatial domain and the detection result from the temporal domain are integrated to produce an integrated lesion detection result.

  • Publication number: 20060064396
    Abstract: System and graphical user interfaces are disclosed for liver disease diagnosis. A visual data manipulation page is used for manipulating one or more liver visual data sets, retrieved together with non-visual information associated with a subject and specific to a liver disease. The visual data manipulation page includes a first area for manipulating the one or more data sets and a second area for providing a plurality of selectable means to activate one or more data manipulation operations to be performed with respect to the one or more data sets displayed in the first area. When the first area is configured to manipulate more than one data set, each image is from a corresponding data set and images from different data sets can be displayed synchronously.

  • Publication number: 20050251014
    Abstract: Method and system for quality assurance in lesion marking is disclosed. A marking is created based on a patient study on display in a manner in accordance with an electronically enforced protocol. One or more features are generated based on the marking. Quality of the marking is assessed based on such computed one or features.

  • Patent number: 5652411
    Abstract: A top loading load cell mass comparator having a load cell and a cantilevered beam connected between the load cell and a weight supporting platform which is self-centering to compensate for off-center loading when moving or replacing weights on the platform. A preload compressive force is applied to the load cell to minimize hysterisis and creep error in the load cell during weight exchanges on the weight supporting platform.
