  • Patent number: 9585857
    Abstract: This invention relates to pharmaceutical composition and methods of using vitamin A and/or RARB agonist for the treatment or prevention of diseases or conditions associated with high fat diet and/or vitamin deficiency. After smoking, high fat diet is said to be the second most lethal habit, causing 300,000 deaths each year in the U.S. alone. High fat diet leads to many health problems, including obesity, stroke, cancer, high blood pressure, diabetes, osteoarthritis, rheumatoid arthritis, multiple sclerosis, heart disease, and diseases in other organs such as liver and kidney.

  • Patent number: 9584617
    Abstract: Various embodiments of the present disclosure provide improved systems and techniques for intelligently allocating cache requests to caches based upon the nature of the cache objects associated with the cache requests, and/or the condition of the caches in the distributed cache system, to facilitate cache system utilization and performance. In some embodiments, an allocation of cache requests may be performed in response to detection of a problem at one of a group of cache servers. For example, in some embodiments, a particular cache server may be entered into a safe mode of operations when the cache's ability to service cache requests is impaired. In other embodiments, an allocation of cache requests may be performed based on an cache object data type associated with the cache requests.

  • Publication number: 20160217595
    Abstract: The present disclosure relates to systems, methods, and computer-readable storage media for segmenting medical image. Embodiments of the present disclosure may locate a target in a three-dimensional (3D) volume. For example, an image acquisition device may provide a 3D medical image containing a region of interest of the target. A processor may then extract a plurality of two-dimensional (2D) slices from the 3D image. The processor may also determine a 2D patch for each 2D slice, wherein the 2D patch corresponds to an area of the 2D slice associated with the target. The processor may also convert the 2D patch to an adaptive filter model for determining a location of the region of interest.

  • Publication number: 20160213947
    Abstract: The present disclosure relates to systems, methods, and computer-readable storage media for segmenting medical image. Embodiments of the present disclosure may locate and track a moving, three-dimensional (3D) target in a patient undergoing image-guided radiation therapy. For example, an adaptive filter model for a region of interest in the patient may be received, wherein the adaptive filter model is based on the target to be tracked. An image acquisition device may obtain a two-dimensional (2D) slice of a region of interest in the patient. A processor may then apply the adaptive filter model to the 2D slice, wherein the adaptive filter model includes an offset value. The processor may also determine a location of the target in the 2D slice based on the adaptive filter model. The processor may also estimate a potential location of the target based on the offset value. The processor may then repeat one or more of the above steps to track the moving target during image-guided radiation therapy of the patient.

  • Patent number: 9256965
    Abstract: Disclosed herein are techniques for translating a first image of a first type to a derived image of a second type. For example, a plurality of similarity indicators can be computed as between a plurality of patches of first image and a plurality of patches of a first atlas image, the first atlas image being of the first type. Weight factors can then be computed based on the computed similarity indicators. These weight factors can be applied to a plurality of data points of a second atlas image to compute a plurality of data points for the derived image such that each of at least a plurality of the data points for the derived image is a function of a plurality of the data points of the second atlas image. Such a technique can be used for pseudo-CT generation from an MR image.

  • Patent number: 9122959
    Abstract: Disclosed herein are techniques for performing automated structure delineation on image data using trained landmark detectors and a shape refinement tool. The landmark detectors can be trained to detect a landmark in the image data based on image features that are indicative of intensity variations over a plurality of windows of the image data points. A machine-learning algorithm can be used to train the landmark detectors. The landmarks in the image data that are detected by the trained landmark detects can be used to initialize an iterative shape refinement to thereby compute a refined shape estimate for a structure of interest such as a prostate.
