A system for three-dimensional (3D) presentation of intravascular ultrasound (US) images was designed. A standard hardware configuration based on personal computer equipment was used for acquisition and processing of image data. Pullback imaging with the US catheter was controlled by a specially designed motor assembly and performed either in equidistant 1-10 mm steps or at a constant retraction speed. Curvature of the vessel was documented on biplane digital subtraction angiograms and the US images were arranged according to the vessel shape in the angiograms. 3D reconstruction appears essential for spatial orientation of intravascular US and may be helpful in the planning of vascular interventions for a better appreciation of the extent and morphology of vascular lesions.
设计了一种用于血管内超声（US）图像三维（3D）呈现的系统。基于个人计算机设备的标准硬件配置用于图像数据的采集和处理。使用美国导管进行回撤成像由专门设计的电机组件控制，并以1-10毫米等距步长或以恒定回撤速度进行。在双平面数字减影血管造影上记录血管的曲率，并根据血管造影中血管的形状排列US图像。三维重建对于血管内超声的空间定位似乎至关重要，并且可能有助于血管介入治疗的规划，以便更好地了解血管病变的范围和形态。
