Reconstruction of Aneurysm Wall Motion

摘要

A framework for image-based reconstruction is provided herein. In accordance with one aspect, the framework receives three-dimensional projection image data of an aneurysm wall in a vascular structure of interest and electrocardiogram signal data, wherein the three-dimensional projection image data is correlated to phases of the electrocardiogram signal data. The framework may sort the three-dimensional projection image data into phase-binned image data according to the phases, and reconstruct three-dimensional layouts of the aneurysm wall in the vascular structure of interest using the phased-binned image data. The framework may then determine the motion of the aneurysm wall between the phases based on the reconstructed three-dimensional layouts.
