1. A method for registering a two-dimensional image data set with a three-dimensional image data set of a body of interest, the method comprising:
obtaining a first spatial parameter of a first registered virtual camera, wherein the first registered virtual camera is positioned corresponding to a first two-dimensional image of the two-dimensional image data set, wherein the first spatial parameter of the first registered virtual camera comprises a position and/or an orientation data which are used to define a position and/or an orientation of the first registered virtual camera corresponding to a three-dimensional subject or the three-dimensional subject corresponding to the first registered virtual camera; and
adjusting a second spatial parameter of a first unregistered virtual camera with the first spatial parameter of the first registered virtual camera for generating an update reconstructed image based on reposition of the first unregistered virtual camera, wherein the first unregistered virtual camera is failed to be positioned corresponding to the first two-dimensional image of the two-dimensional image data set,
wherein the second spatial parameter of the first unregistered virtual camera comprises a position and/or an orientation data which are used to define a position and/or an orientation of the first unregistered virtual camera corresponding to the three-dimensional subject or the three-dimensional subject corresponding to the first registered virtual camera.
