  • Publication number: 20150213633
    Abstract: Exemplary devices, procedures and computer-readable mediums for providing a projection image associated with at least one target. The projection image can be formed from a plurality of locations of a source arrangement. At each source location, a plurality of panoramic projection images associated with a target can be acquired. At least two of the panoramic projection images can be obtained at view angles which are different from one another. These panoramic projection images can be stitched together or otherwise combined. A resulting image can then be generated using a computed tomography procedure based on the stitched or combined projection images that are generated at the plurality of location.

  • Publication number: 20130289400
    Abstract: Exemplary embodiments of an apparatus and a system for generating at least one radiation are provided. For example, an exemplary system can include at least one radiation source arrangement configured to generate the at least one radiation, is translatable on at least one track, and is pivotable about at least two axes; a tracking assembly configured to track an internal movement of a target tissue within a living structure and provide tracking information to facilitate directing the radiation(s) generated by the radiation source arrangement(s) at the target tissue; and a collimator assembly configured to move in a curved path so as to shape and direct the at least one radiation generated by the radiation source arrangement(s).
