Atherosclerotic plaque motion trajectory analysis from ultrasound videos
Date Issued
2006
Abstract
The paper describes the computation of motion
trajectories in ultrasound videos of atherosclerotic plaques.
Preliminary results indicate that motion trajectories follow the
cardiac cycles, forcing motions from different parts of the
plaque and arterial walls to appear in phase. Based on the
periodicity of the motion, we found that a Fourier series, using
a small number of harmonics, can approximate the periodic
motion due to the cardiac motion cycle. Furthermore, plaque
motion exhibited larger deviations and more abrupt changes
than arterial wall motion.
