The sequential detection of artery sectional area using optical flow technique
Kamil Říha, I. Potucek · 2009
The main goal of presented work is reliable detection of sectional area of an artery during a time in the in the B-mode ultrasound video sequence frames. Presented algorithm is a part of a long-term project [1]. The innovative concept of the work rests in the automatic monitoring of artery border tissue movement using the Lucas-Canade optical flow technique [2]. Invariant features uniformly selected in the artery border area are tracked in whole video sequence. Volume cut is estimated by using fitted ellipse from set of these points, so that the most suitable artery shape will be denoted in every frame. Output cardiac cycle curve can be used for analysis of volumetric changes of artery in arbitrary body part which can be displayed using a B-mode sonograph.
