摘　　要：随着近年来高新技术的迅速发展，对医学图像处理的需求日益增加，尤其是医学图像三维重建技术，表明其在诊断中的重要性。在当前软件当中，成本和计算能力都没有显示出好的效果。针对这种情况，提出了一种基于VTK的三维重建方法，它是对DICOM源图像进行灰度插值、光线投射和体绘制等一系列操作实现的。该方法对CT、MRI和超声图像进行体绘制，可以提供更多可视的信息帮助医疗工作者做出准确的诊断。With the advanced technology in recent years, the increasing demand for an effective medical imaging system, especially the three-dimensional medical image reconstruction, has addressed its significance in diagnosis. None of the existing software show efficiency in terms of cost and computational performance. Owing to this fact, a method of 3D reconstruction using VTK has been discussed in this paper, which has been achieved through a series of processes including DICOM source data, gray interpolations, ray casting and volume rendering. The method shows its future utilities in CT, MRI and Ultrasound image volume rendering, and provides a more informative view in order to assist the medical worker.
