【摘要】 本文论述了超声图像多维重建与可视化系统MURVS的设计与实现。MURVS包括四个模块:数据输入输出模块、图像分割与排列模块、多维重建模块以及动态可视化模块。作者首先介绍了MURVS使用的相关算法。然后描述了MURVS系统设计的主要过程,包括模块设计、动态可视化以及代码实现。病例实验表明,MUR-VS能够在4s内重建一个病例在一个心动周期内的所有三维数据场,并流畅地动态显示重建结果。MURVS清晰地再现了心脏的运动情况,医生可以选择不同角度、不同层面来查看心脏的病变情况,观察心脏的收缩和舒张节律是否正常、心房和心室的容积是否有异常等,从而有助于医生形成更加准确的诊断结果。更多还原

【Abstract】 The design and development of multi-dimensional ultrasonic reconstruction and visualization system (MURVS) have been described in the present paper. This system is basically composed of four modules:the data input/output module,image segmentation and arrangement module,multi-dimensional reconstruction module,and the dynamic visualization module. At first,some algorithms used in the system are introduced by the authors,including the AVI segmentation algorithm,three-dimensional interpolation algorithm,and volume rendering algorithms. Then the key questions of techniques to be discussed are:how to design the main modules,how to solve the dynamic visualization problem,and how to implement the system. The experiments indicate that MURVS is able to reconstruct all three-dimensional data fields in one cardiac cycle of a patient within 4 seconds,and dynamically display the motion of the heart. It allows the medical professionals to select different parameters when observing the reconstructed results. This is very helpful for medical professionals to reach more accurate diagnoses of their patients’ diseases.更多还原
