彩色多普勒方法可以利用超声波的多普勒效应实时测量流速，适合于观察血流，并有助于诊断循环系统疾病。然而，测量的结果被表示为2-D图像，这对于理解复杂流的状态没有用。本文介绍了彩色多普勒血流图像的三维可视化方法。为了诊断和研究，血流的可视化必须满足以下特征：（1）客观性;（2）交互性;（3）多方面性。该系统通过提供实时可视化方法和直观的界面满足上述要求。此外，与幻影通道的实验表明，该系统使观察者能够识别整个流的状态，如湍流的发生和射流的区域。
The color Doppler method, which can measure velocity of a flow in realtime using the Doppler effect of ultrasound, is suitable for observation of a blood flow and has contributed to diagnosis of circulatory illness. However, the result of measurement is represented as a 2-D image, which is not useful for understanding a state of a complex flow. This paper presents 3-D visualization methods of a blood flow from color Doppler images. For diagnosis and investigation, the visualization of a blood flow must fulfill the following features : (1) objectivity (2) interactivity and (3) multi-aspect. The proposed system meets the above requirements by providing realtime visualization methods and intuitive interfaces. Moreover, an experiment with a phantom channel shows that the proposed system enables observers to recognize a state of an entire flow, such as occurence of turbulence and an area of regurgitant jets.
