Abstract:
The present disclosure provides method and apparatus for marking a target in a 3D image. The method include steps of: acquiring Computed Tomography (CT) image data of a scene; rendering a 3D image of the scene using ray casting based on the CT image data; removing a transparent region from the 3D image based on a fixed 2D transfer function; and marking the target in the 3D image.
