Synthetic transmit aperture (STA) has been widely investigated in ultrasound system recently with characteristics of high frame rate and low hardware cost. Since the high-resolution image (HRI) of STA is formed by summation of low-resolution images (LRIs), it is susceptible to inter-firing motions. In this paper, we propose a low-complexity global motion compensation algorithm. We use the common region...
Synthetic transmit aperture (STA) has been widely investigated in ultrasound system recently due to its high frame rate and low cost characteristics. Since the highresolution image (HRI) of STA is formed by summation of low-resolution images (LRIs), it is susceptible to motion between firings. In this work, we propose a low-complexity two-dimensional motion compensation algorithm. The velocity and...
