摘要

血管疾病可发生在上肢,病变可跨越整个血管长度。超声多普勒成像是诊断血管疾病最常用的方法之一。然而,传统的二维(2D)超声多普勒成像不能在一张图像中捕获长血管的整个长度。医学专业人员经常不得不费力地利用二维超声图像重建三维(3D)数据来定位病变,特别是对于大血管。三维超声多普勒成像可以更直接地显示血管的形态结构和病变的分布,比二维成像提供更全面的视角。在这项工作中,我们提出了一种双模态的大范围三维容积超声多普勒成像系统,其中采用高清摄像机自动跟踪超声换能器的运动,同时捕获相应序列的二维超声多普勒图像。我们使用我们提出的系统和x射线计算机断层扫描(X-CT)分别对人体手臂进行了实验。对比结果证明了该系统在手臂血管疾病诊断中的潜在价值。

Volumetric B-mode ultrasound and Doppler Imaging: Automatic Tracking With One Single Camera.

Vascular diseases may occur in the upper extremities, and the lesions can span the entire length of the blood vessel. One of the most popular methods to identify vascular disorders is ultrasound Doppler imaging. However, traditional two-dimensional (2D) ultrasound Doppler imaging cannot capture the entire length of a long vessel in one image. Medical professionals often have to painstakingly reconstruct three-dimensional (3D) data using 2D ultrasound images to locate the lesions, especially for large blood vessels. 3D ultrasound Doppler imaging can display the morphological structure of blood vessels and the distribution of lesions more directly, providing a more comprehensive view compared to 2D imaging. In this work, we propose a wide-range 3D volumetric ultrasound Doppler imaging system with dual modality, in which a high-definition camera is adopted to automatically track the movement of the ultrasound transducer, simultaneously capturing a corresponding sequence of 2D ultrasound Doppler images. We conducted experiments on human arms using our proposed system and separately with X-ray computerized tomography (X-CT). The comparison results prove the potential value of our proposed system in the diagnosis of arm vascular diseases.
