Method, Apparatuses and System for Presenting a Target, and a Storage Medium and a Program Product

Techniques are provided for presenting a target in X-ray imaging. The techniques include acquiring N 3D images of an imaging target, with each 3D image being provided with a respective camera coordinate system and N being a positive integer greater than or equal to 2. The techniques also include generating a virtual 3D image on the basis of the N 3D images, with a camera coordinate system of the virtual 3D image taking an X-ray source as the origin, and converting the virtual 3D image into a 2D image. Finally, the technique includes presenting the 2D image. By means of the 2D image, the X-ray imaging target may be fully observed. In addition, distortion, such as warping or deformation, is not present in an imaging region and an automatic exposure region.
