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.
