A new method is introduce for the three-dimensional (3D) reconstruction of the coronary stents in-vivo utilizing two-dimensional projection images acquired during rotational angiography (RA). The method is based on the application of motion compensated techniques to the acquired angiograms resulting in a temporal snapshot of the stent within the cardiac cycle. For the first time results of 3D reconstructed coronary stents in vivo, with high spatial resolution are presented. The proposed method allows for a comprehensive and unique quantitative 3D assessment of stent expansion that rivals current x-ray and intravascular ultrasound techniques.
介绍了一种利用旋转血管造影（RA）期间采集的二维投影图像对体内冠状动脉支架进行三维（3D）重建的新方法。该方法基于将运动补偿技术应用于采集的血管造影图像，从而获得心动周期内支架的时间快照。首次展示了体内3D重建冠状动脉支架的高空间分辨率结果。所提出的方法允许对支架扩张进行全面且独特的定量3D评估，可与当前的X射线和血管内超声技术相媲美。
