Hemodynamic parameters estimation from cineangiograms using optical flow

In this paper, physical constraints are used to adapt known optical flow algorithms to study blood circulation in healthy and stenosed arteries by tracking dye dispersion using radiological image sequences. To this end, the penalty functional method of constrained optimization is put forward. Simulated radiological images taking into account blood flow and contrast medium dispersion are computed to test the proposed algorithms. Results from these simulated radiological images are presented and discussed.
