摘要：

<正> The purpose of the study is to reconstruct the coronary arteries in 3 dimension (3D) from serial intravascular ultrasound (IVUS) images generated during a pullback of IVUS catheter. Slowly pullback. real-time, cross-sectional IVUS images of 18 patients (2 with normal coronary arteries. 1 with coronary aneurysm. and 15 post PTCA) were obtained by using a 20 MHz. 3.5F IVUS catheter and recorded on video tape. A series of 90-frame consecutive IVUS images were digitized into a SUN Spare 11 workstation. Digitized data were reconstructed to 3D images with use of voxel space modeling and were generated in both sagittal and cylindrical formats. The sagittal format results in a longitudinal
