摘要:

超高频超声(UHFUS)能够可视化手中高度变形的中小血管。复杂的基于血管的测量,例如内膜壁厚度和血管壁顺应性,需要在B扫描之间进行亚毫米血管跟踪。我们的快速基于GPU的方法结合了局部相位分析,距离正则化水平集和扩展卡尔曼滤波器(EKF)的优点,快速分割和跟踪变形血管轮廓。我们验证了35 UHFUS序列的血管在手中,我们展示了该方法的可转移性,以5个更多样化的数据集,由传统的高频超声(HFUS)机。据我们所知,这是第一个能够快速分割和跟踪2D UHFUS图像中可变形血管轮廓的算法。它也是2D HFUS图像最快、最准确的系统。

英文摘要:

Ultra High Frequency Ultrasound (UHFUS) enables the visualization of highly deformable small and medium vessels in the hand. Intricate vessel-based measurements, such as intimal wall thickness and vessel wall compliance, require sub-millimeter vessel tracking between B-scans. Our fast GPU-based approach combines the advantages of local phase analysis, a distance-regularized level set, and an Extended Kalman Filter (EKF), to rapidly segment and track the deforming vessel contour. We validated on 35 UHFUS sequences of vessels in the hand, and we show the transferability of the approach to 5 more diverse datasets acquired by a traditional High Frequency Ultrasound (HFUS) machine. To the best of our knowledge, this is the first algorithm capable of rapidly segmenting and tracking deformable vessel contours in 2D UHFUS images. It is also the fastest and most accurate system for 2D HFUS images.
