This paper investigates a 3D reconstruction based on the ultrasonic scanned data for tissue mimicking material (TMM) sample. A two-step varied window filter is developed to smooth ultrasound backscatter signals at first. Next, the anisotropic diffusion filter with a triangular window is presented to reduce the noise of the 2D images by aligning one-dimensional signals. Finally, the 3D structure of the object embedded in the TMM sample is reconstructed using the detected edges images. The performance of the proposed method is analyzed and validated through a number of experiments in both 2D imaging and 3D reconstruction.
本文研究了基于组织仿体材料（TMM）样本超声扫描数据的三维重建。首先开发了一种两步可变窗口滤波器对超声后向散射信号进行平滑处理。接下来，提出了一种带三角形窗口的各向异性扩散滤波器，通过对齐一维信号来降低二维图像的噪声。最后，利用检测到的边缘图像重建TMM样本中嵌入物体的三维结构。通过在二维成像和三维重建方面的大量实验，对所提方法的性能进行了分析和验证。
