Abstract
An apparatus for measuring parameters preparatory to a stent replacement of an aneurytic blood vessel in a patient (26) includes a computed tomography (CT) scanner (10) that acquires image data (28) corresponding to multiple two-dimensional image slices. A reconstruction processor (32) reconstructs a three-dimensional image representation (34) from the image data (28). A tracking processor (40) produces a tracked vessel (92) including at least a centerline (80) and selected vessel boundaries (86). A user interface (44) displays a rendering (242) of the image representation to an associated user (42), measures selected vascular parameters corresponding to the stent parameters (276), and graphically superimposes the measured parameters on the rendering of the image representation (270, 272).
