Clutter ultrasound
WebApr 10, 2024 · This adaptive SVD filtering method was applied to each block of ultrasound data to extract microbubble signal from tissues and noise. After clutter filtering, individual microbubbles were localized using the radial symmetry (RS) algorithm [30], which utilizes the intensity gradient to find the center of a microbubble. The intensity gradient in ... WebIn this work, a novel technique for real-time clutter rejection in ultrasound Color Flow Imaging (CFI) is proposed. Suppressing undesired clutter signal is important because clutter prohibits an unambiguous view of the vascular network.
