Isolation of aneurysm and parent vessel in volumetric image data

Abstract

A framework for isolating an aneurysm and parent vessel in volumetric image data is provided herein. In accordance with one aspect, the framework generates a refined mask by performing region growingstarting at an aneurysm dome point to eliminate vessels that are indirectly connected to an aneurysm or parent vessel in volumetric image data. A final mask may be generated based at least in part onthe refined mask by eliminating any kissing vessel connected with the aneurysm from the refined mask. The final mask may then be used for segmentation of the aneurysm and the parent vessel in the volumetric image data.

Description

technical field [0001] The present disclosure relates generally to digital image data processing, and more particularly to isolation of an aneurysm from its parent vessel in volumetric image data. Background technique [0002] An aneurysm is a localized, congestive dilation or bulge of a blood vessel caused by disease or weakening of the vessel wall. Aneurysms can appear anywhere there are blood vessels, although they are most commonly found in arteries. Aneurysms most commonly occur in arteries at the base of the brain, in the circle of Willis, and in the aorta. Rupture and blood clotting are the risks involved with an aneurysm. In particular, if the patient suffers from elevated blood pressure, this bulge in the blood vessel can burst at any time and cause bleeding and possibly death. Except for ruptures in extremities, the risk of death is higher. The larger an aneurysm becomes, the more likely it is to burst. [0003] X-ray C-arms are routinely used in medicine to a...

Problems solved by technology

As shown, aneurysms 102a-h have been incorrectly detected due to leakage (or overflow) into adjacent vessels outside the region of interest
