First Claim
Patent Images
1. A system for imaging an artery contained in an arterial tree, the artery having an axis, comprising:
- a a microprocessor configured to aa generate a three-dimensional reconstruction of the arterial tree from two or more angiographic images of the arterial tree obtained from different perspectives;
ab determine an orientation of the axis of the artery in the arterial tree;
ac determine from the three-dimensional reconstruction of the arterial tree at least one perspective of the artery perpendicular to the axis of the artery; and
ad generate a three dimensional reconstruction of the artery from angiographic images obtained essentially from the determined at least one perspective.

Abstract
A method and system for imaging an artery contained in an arterial tree. A microprocessor generates a three-dimensional reconstruction of the arterial tree from two or more angiographic images obtained from different perspectives. The orientation of the axis of the artery in the arterial tree is then determined, and a perspective of the artery perpendicular to the axis of the artery is determined. A three dimensional reconstruction of the artery from angiographic images obtained from the determined perspective is then generated.
