3D-2D IMAGE REGISTRATION FOR MEDICAL IMAGING

摘要

A method of 3D-2D registration for medical imaging includes the following steps: providing a first input interface for acquiring a three-dimensional image; providing a second input interface for acquiring a fixed two-dimensional image using an imaging system that includes a source and a detector and that has an unknown source-detector geometry; initializing image transformation parameters and source-detector geometry parameters; generating a reconstructed two-dimensional image from the three-dimensional image using the image transformation parameters and the source-detector geometry parameters; determining an image similarity metric between the fixed two-dimensional image and the reconstructed two-dimensional image; and updating the image transformation parameters and the source-detector geometry parameters using the image similarity metric, and a corresponding non-transitory computer-readable medium and apparatus.
