    摘要： Disclosed is a method and apparatus for detecting endplates of vertebra, comprising the steps of providing a filtered curvature map derived from filtering an intensity curvature map of a spine image in a direction relative to a spine axis, computing minimum and maximum curvature projections for each point along said spine axis, at a plurality of points on said spine axis, computing a score from said curvature projections, said score indicating the likelihood that the point is located on an endplate, and subjecting said score calculation to at least one of the following constraints (1) that the angle between neighboring endplates not exceed a certain value, and (2) that the variation in height of vertebra of said spine image should satisfy a global model.

    摘要： The present disclosure is directed at a system and method for analyzing clinical trial data over a network. The system and method specifics image protocols, encodes a number of protocols and communicates that information to an acquisition unit that appends the protocols to a digital image. When the image needs to be analyzed to gather clinical trial data, the encoded information is extracted and the correct software application is initialized and used to analyze the image.

    摘要： Methods, systems, and programs for real-time surgical procedure assistance are provided. A first set of 3D poses of the 3D points on the organ may be received. An electronic organ map built for the organ via pre-surgical medical information may be retrieved. A tissue parameter of the organ may be obtained based on the first set of 3D poses and their corresponding 3D poses from the electronic organ map. A deformation transformation of the electronic organ map may be calculated based on the obtained tissue parameter and the first set of 3D poses during the surgical procedure. The deformed electronic organ map may be projected onto the organ with respect to the first set of 3D poses during the surgical procedure.

    摘要： A method and system is provided for data/process sharing. A decapsulating unit is provided and resides on first system where a first application system resides. The decapsulating unit monitors, on the first system, when encapsulated data from a second application system residing on a second system, is present in the first application system. The encapsulated data, once present on the first system, is decapsulated by the decapsulating unit to obtain a trigger corresponding to the second application system and encapsulated in the encapsulated data. The obtained trigger is analyzed and the second application system is launched on the first system based on the trigger.
