Abstract
In coronary angiography the coronary blood flow velocity
can be assessed by tracking a contrast agent in
an image sequence. The contrast agent flow velocity
is used to estimate the functional behavior of the coronary
arteries using TIMI frame count (TFC). In this paper
we descibe the 3D reconstruction algorithm used
in our method towards the automation of TFC. The
method creates a two dimensional map of the contrast
agent in which the opacification of the vessel centerline
is plotted against time. This map is used to find
the velocity of the contrast agent and subsequently the
TFC. The vessel centerline is obtained using the Fast
Marching Method to find the minimum cost path between
the catheter point and the end of the vessel. The
determination of the start and endpoint is estimated
using a 3D model reconstructed from bi-plane 2D image
data. The final reconstructed coronary model only
includes the segments matching our error criterion.
