摘要： The present invention provides a method and system for progressive multi-resolution three-dimensional image reconstruction using region of interest information. The method and system significantly reduces the amount of time required to display high quality three-dimensional fluoroscopic images by utilizing progressive multi-resolution image reconstruction techniques. In addition, by employing manual or automated selection of one or more regions of interest in which to focus the progressive image reconstruction, high quality 3D images of region(s) of interest may be obtained soon after image data acquisition.

摘要： Certain embodiments of the present invention provide systems and methods for image composition. Certain embodiments include acquiring a first image of an object using an imager, obtaining first positional information for the imager with respect to the object, acquiring a second image of the object using the imager, obtaining second positional information for the imager with respect to the object, and creating a composed image using the first and second images. A spatial relationship between the images is maintained using the positional information. A composed image may be created by constructing a memory map of image data related to the object and inserting the images into the memory map based on the positional information, for example. A composed image may be created by combining the images based on the positional information, for example.
