Abstract

Accurate measurement of blood flow velocity profiles is important for diagnosing diseases such as heart failure, carotid stenosis, and renal failure. Speckle decorrelation (SDC) was developed to measure 2D out-of-plane blood flow over the entire luminal area using a conventional 1D array transducer. One of the main challenges in SDC is the tissue clutter interference with blood. Adaptive clutter filters can suppress the clutter from backscattered signals in ultrasound blood-flow imaging. This study aims to evaluate the performance of adaptive clutter filters, including the discrete cosine transform (DCT), polynomial regression (PR), and singular value decomposition (SVD), for SDC-based blood flow velocity measurement via ultrasound simulations. Among the adaptive clutter filters, the SVD filter with Pareto scaling exhibits the best performance for clutter rejection and SDC-based flow velocity measurements. The benefit of this study is that it significantly improves the accuracy of SDC-based blood flow velocity measurements.

基于斑点解相关性的血流测量的自适应杂波滤波器
准确测量血流速度曲线对于诊断心力衰竭、颈动脉狭窄和肾功能衰竭等疾病非常重要。斑点重复相关技术(SDC)的开发是为了使用传统的一维阵列传感器测量整个管腔区域的二维平面外血流。SDC 面临的主要挑战之一是组织杂波对血液的干扰。自适应杂波滤波器可以抑制超声血流成像中反向散射信号的杂波。本研究旨在通过超声模拟评估自适应杂波滤波器(包括离散余弦变换(DCT)、多项式回归(PR)和奇异值分解(SVD))在基于 SDC 的血流速度测量中的性能。在自适应杂波滤波器中,具有帕累托比例的 SVD 滤波器在杂波抑制和基于 SDC 的血流速度测量方面表现最佳。这项研究的益处在于它显著提高了基于 SDC 的血流速度测量的准确性。
