Abstract

The present disclosure provides a method for rendering of CT image data. The method includes acquiring 2D image data of a background and 2D image data of a target; rendering the 2D image data of the target into a 3D image of the target to obtain a first hit position of a ray; rendering the 2D image data of the background into a 3D image of the background; adjusting the 3D image of the background based on the first hit position; and synthetically rendering the 3D image of the background and the 3D image of the target. The present disclosure also provides apparatus for implementing the method.
