| 摘 要： | 传统的超声心脏图像三维重建技术只限于描述三维及动态三维解剖结构,不能对心脏动态功能做出准确有效的评价。本研究将建立组织多普勒超声心脏图像的动态三维重建方法,通过超声医学图像三维重建技术和组织多普勒超声成像技术的结合,重建心脏运动的动态三维加速度场,为心脏功能的准确评价提供一条新的途径。论文解决了加速度矢量场重建过程中关键的矢量插值和融合显像的问题,从组织多普勒加速度图像中分别重建心肌运动三维加速度场和三维解剖结构,并进行融合显像。试验结果证明了二者之间相对空间位置正确,该方法可以为心脏疾病的诊断和心脏功能的评价提供更多信息,在心脏靶点起搏和心内消融等领域有潜在的应用价值。 |

| Abstract: | Traditional 3D ultrasound reconstruction system can just depict 3D anatomical structure, so it is very difficult to give an accurate assessment of the functionality of the heart. In this study, a dynamic 3D reconstruction method of tissue Doppler ultrasound heart images is set up based on the combination of 3D reconstruction and tissue Doppler imaging technique. Dynamic 3D acceleration field of heart movement is reconstructed to supply a new approach of accurate assessment of functionality of the heart. The key problem of vector interpolation and fusion imaging in the process of acceleration vector field reconstruction is solved. The 3D acceleration field of heart movement and anatomical structure is reconstructed separately from the original tissue Doppler acceleration images and showed in the same field. The experimental results testified that the 3D space relationship of acceleration and anatomical structure is correct and this method can supply more information for the assessment of heart functionality. |
