Patent abstract
Systems and methods are provided for angiographic roadmapping. In accordance with one aspect, the framework generates one or more two-dimensional (2D) digitally reconstructed radiograph (DRR) images from a four-dimensional (4D) digital subtraction angiography (DSA) image volume. A maximally opacified image is generated from at least one of the one or more 2D DRR images over a window of time. The maximally opacified image may then be integrated with a live fluoroscopic image and displayed for angiographic roadmapping.
