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:
defining a first vector of a registered virtual camera in a coordinate system of the three-dimensional image data set;
obtaining a first transformed vector of an unregistered virtual camera in the coordinate system of the three-dimensional image data set by transforming the first vector of the registered virtual camera through at least one transforming matrix;
defining a focal point of the unregistered virtual camera at a reference point of the two-dimensional image data set in the coordinate system of the three-dimensional image data set; and
repositioning the unregistered virtual camera according to the first transformed vector and the focal point of the unregistered virtual camera for generating an update reconstructed image based on the reposition of the unregistered virtual camera.
