摘要：

背景：医学图像的三维模型，能够准确的三维结构在临床诊断上凸显重要性。
目的：对连续多帧的超声图像进行三维结构重建。
方法：利用可视化工具VTK和图像的配准分割工具ITK，在VC++的平台下，采取直接体绘制的方法，对连续多帧的DICOM医学超声图像进行了三维重建，并且用户可以利用鼠标与图片进行交互，实现任意角度的旋转。
结果与结论：合成体绘制在重建中的效果较优，相对而言更适合超声图像的三维重建。

Abstract:

BACKGROUND: Three-dimensional model of medical images can provide direct visual reference for medical workers. Accurate three-dimensional structure of cardiac has an increasingly prominent on the clinical diagnosis.
OBJECTIVE: To accomplish the three-dimensional structure reconstruction of continuous multi-frame ultrasound images from the B scan.
METHODS: With the help of the toolkits including Visualization Toolkit (VTK) and Segmentation & Registration Toolkit (ITK), the method of Ray Casting was adopted to realize the three-dimensional construction of cardiac ultrasonic image using the given DICOM continuous multi-frame of medical ultrasound images, under the platform of VC++. In the designed system, user could interact with the three-dimensional images through clicking the mouse and figure the image from any view.
RESULTS AND CONCLUSION: The results show that composite volume rendering is more feasible in the reconstruction.
