P2B-3 A New Motion Estimation and Compensation Method for Real-Time Ultrasonic Synthetic Aperture Imaging

In synthetic aperture imaging (SAI), it is well known fact that focusing quality will be degraded without estimation and compensation of the target movement. Various methods are available for compensation of the target movement. In this paper, simpler and more robust computational method compare to...

Description
Summary:In synthetic aperture imaging (SAI), it is well known fact that focusing quality will be degraded without estimation and compensation of the target movement. Various methods are available for compensation of the target movement. In this paper, simpler and more robust computational method compare to the conventional method will be presented. Presented method combines autocorrelation method of conventional two dimensional- tissue Doppler imaging (2D-TDI) with SAI, only the transmit sequence is appropriately changed. Computer simulation and the phantom experiment are used to show effectiveness of the presented method.
