System And Method For Time-Resolved, Three-Dimensional Angiography With Flow Information

摘要

A system and method are provided for generating time resolved series of angiographic volume data having flow information integrated therewith. The method includes generating a series of 3D time-resolved vascular volumes from time resolved x-ray projection data and calculating blood velocity in the vascular volumes x-ray projection data to determine a rate of change of calculated contrast material arrival time at positions along the vascular volumes. The method also includes displaying the 3D time-resolved vascular volumes with a graphical indication of blood velocity in the vascular volumes.

1. A system for generating time resolved series of angiographic volume data having velocity or velocity-derived information integrated therewith, the system comprising:
an image processing system configured to:
receive angiographic volume data acquired from a subject having received a dose of a contrast agent using an imaging system;process the angiographic volume data to generate angiographic volume images;process the angiographic volume data to derive flow information associated with vessels in the angiographic volume images; and a display configured to display the angiographic volume images of the subject including the flow information coupled with at least a portion of the vessels in the angiographic volume images.
