摘要： 针对医学图像数据的特点以及应用中的实际要求,通过对不同重建算法的比较,提出了以光线投射技术为基础的医学图像三维重建方案,同时提出了基于空间跳跃技术和序列相关性的综合加速算法,对重建算法进行加速·最后在PC机平台上实现了该方案,获得了接近实时的交互速度·由于所有重建算法的核心都是光线投射技术,因此在获得高质量重建结果的同时,极大地降低了系统的复杂性,提高了开发的效率,为医学图像三维重建的实用化提供了一种非常好的解决方案·

Abstract: Compared with different reconstruct algorithms and taking account of the features of medicine images and actual requirements, a scheme based on the ray-casting technique was proposed to solve the problem of the 3D reconstruction of medical images. To improve the rendering speed of ray casting and make the technique shown in the scheme a practical routine in medical applications, a synthesized accelerate algorithm based on space leaping and series correlativity was suggested. Finally, a 3D reconstruction system of medicine image in the proposed scheme was implemented on a PC platform to obtain a nearly real-time interactive speed. Because the kernel of all these reconstruction algorithms is the ray-casting technique, a high quality result of reconstruction can be acquired. At the same time, the complexity of the whole system can thus be reduced greatly with the R and D efficiency improved. The results are very helpful to the development of the 3D reconstruction of medicine images.
