  • Publication number: 20160202336
    Abstract: A new method is developed to accelerate high-resolution magnetic resonance spectroscopic imaging (MRSI). The method is built on a low-dimensional subspace model exploiting the partial separability of high-dimensional MRSI signals and uses this subspace model for data acquisition, processing, and image reconstruction. Specifically for two and three dimensional MRSI with one spectral dimension, this method sparsely samples the corresponding (k,t)-space in two complementary data sets, one with dense temporal sampling and high signal-to-noise ratio but limited k-space coverage and the other with sparse temporal sampling but extended k-space coverage. The reconstruction is then done by estimating a set of temporal/spectral basis functions and the corresponding spatial coefficients from these two data sets. The proposed subspace model can be further extended to incorporate multiple signal components for nuisance signal removal in 1H-MRSI and more generalized reconstruction methods.

  • Patent number: 9389767
    Abstract: A method for tracking an object in a plurality of frames includes obtaining a contour of an object in a frame. For each remaining frame among the plurality of frames, the following steps are performed. A probability map generator generates a plurality of probability maps containing probability values for one or more pixels for a current frame. A contour is estimated for the current frame based on the plurality of probability maps. User input is obtained for refining the estimated contour. Based on the user input, one or more local regions to be added and/or removed are identified and recorded in a local region list. The local region list is maintained and updated during the tracking process and is used together with the probability map generator.

The server receives a query segmentation request including a search query, and the search query further includes an ordered sequence of semantic elements. Each semantic element is correlated with one or more predetermined search terms each at least including the respective semantic element. The server further modifies the search terms by replacing irrelevant semantic elements with segmentation identifiers. The modified search terms are then combined to form combined search queries each of which includes the ordered sequence of semantic elements and at least one segmentation identifier that separates the semantic elements. A specific combined search query is identified based on search probabilities of the combined search queries, and the search query is segmented according to a location of at least one segmentation identifier in the specific combined search query.
