    摘要: A method for performing a volume rendering of an image uses a computer having a processor, memory, and a display. The method includes globally segmenting image data that represents an image to thereby locate boundaries in the image, determining regional opacity functions using the image data in a vicinity of the boundaries, and volume rendering the image data utilizing the regional opacity functions to display an image. The method provides a presentation of improved images of structures. These improved images are obtained using a regional optimization of the opacity function such that the perceived object boundary coincides more closely with a segmented boundary.

    摘要: A method and system for slice alignment in multiple image views are provided. The method includes determining an adjustment of one of a plurality of image views to align an imaged object with at least one alignment marker. The method further includes updating the plurality of image views based on the adjustment. The updating includes at least one of rotating and translating the image views with respect to an intersection of the at least one alignment marker with another alignment marker.

    摘要: A method is provided for improving a segmentation of a 3D image and/or validating a segmentation of a 3D image includes rendering an acquired 3D image and a segmentation of the acquired 3D image on a segmentation display that has at least one spatially fixed slice and an interactive slice with a reference mark corresponding to the cursor location in the spatially fixed slice or slices on the display. The method further includes utilizing an interactive user input to update image data of the interactive slice and the reference mark to coincide with the cursor in the spatially fixed slice or slices. The method further includes using the cursor and the reference mark to verify that cursor locations on the boundaries of the segmentation of the acquired 3D image correspond to object boundaries in the image data of the interactive slice.
