Accelerated block-based 2D motion estimation for pre-processing in elastography

Résumé

In intravascular ultrasound, we investigate vessel motion due to pulsating blood flow. Relatively large lateral displacements are observed. To incorporate these, we propose an initially 2D displacement estimation based on an accelerated block matching algorithm for preprocessing. In this paper, an accelerated algorithm based on the Successive Elimination Algorithm is described. Furthermore, we evaluated the algorithm based on intravascular ultrasound data. The proposed algorithm is compared to an exhaustive search. The results show a reduction in search time and identical motion field.
