What is it about?
This is to extract the corresponding points in two x-ray images. The next step is to reconstruct the image in three dimensions using algorithms like Discrete Linear Transform (DLT). The reconstruction of 3D scenes can be described as taking as input a pair of 2D stereo photos and producing as output a scene of 3D points constructed using those photos.

Why is it important?
3D reconstruction from multiple images is the creation of three-dimensional models from a set of images. It is the reverse process of obtaining 2D images from 3D scenes. The essence of an image is a projection from a 3D scene onto a 2D plane, during which process the depth is lost. The 3D point corresponding to a specific image point is constrained to be on the line of sight.
Perspectives
In recent decades, there is an important demand for 3D content for computer graphics, virtual reality and communication, triggering a change in emphasis for the requirements. Many existing systems for constructing 3D models are built around specialized hardware (e.g. stereo rigs) resulting in a high cost, which cannot satisfy the requirement of its new applications.
