Abstract
A method for registering a two-dimensional image data set with a three-dimensional image data set of a body of interest is discloses herein. The method includes the following steps: defining a first vector of a registered virtual camera in a coordinate system of the three-dimensional image data et; 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.
