> 中文摘要: 传统的自由臂三维超声成像系统不能做到实时交互的重建.介绍了实时交互的自由臂三维超声成像系统RIF-3DUSIS(real-time and interactive freehand three-dimensional ultrasound imaging system),包括其整体设计思想、三维重建方法和软硬件系统结构.RIF-3DUSIS的特点是:(1) 在扫描过程中,实时进行采集和三维重建,并使得操作者能够对重建体模型进行实时的交互操作;(2) 在扫描的同时,不仅通过动态显示重建体提供可视化的反馈信息,而且不断更新显示已重建的比率,以定量地引导扫描重建的进度;(3) 在每一步操作之前都会给出提示信息,引导操作者进行操作.实验结果表明了RIF-3DUSIS实时重建的有效性和动态交互的灵活性.

Abstract:Conventional freehand three-dimensional (3-D) ultrasound imaging systems cannot achieve real-time and interactive reconstruction. The overall design idea, 3-D reconstruction method, and hardware/software system structure of the developed real-time and interactive freehand 3-D ultrasound imaging system, which is called RIF-3DUSIS, is introduced in this article. The characteristics of RIF-3DUSIS are as follows: (1) acquisition, 3-D reconstruction, and interactive manipulation of the reconstructed volume model in real time during scanning process; (2) While scanning, not only displaying reconstructed volume dynamically to provide visual feedback, but also updating display of reconstructed ratio sequentially to conduct reconstruction plan quantitatively; (3) Showing instruction information before each operation step so as to instruct operator’s work. Experimental results indicate the effectiveness of real-time reconstruction and the flexibility of dynamic interaction of RIF-3DUSIS.
