摘要 研究快速获取血管造影的方法,提出了一种基于有序体数据的新的最大密度投影算法.该算法采用Shear-Warp投影思想,通过调整对有序体数据遍历的阈值实现快速绘制,在不影响显示有效信息的情况下,对中等规模的体数据能达到每秒10帧以上的绘制速度,并在微机上实现了血管造影图像的实时绘制. A new maximum intensity projection algorithm is presented based on the sorted volumetric data. the new algorithm adopts the principle of projection from the ShearWarp algorithm, which is the fastest projection algorithm. By means of adjusting the threshold, which determines the termination of traversing the sorted volumetric data, realtime rendering can be realized on the personal computer. The proposed algorithm reaches the speed of 10 frames/second against the medium volume data without affecting the display of effective information.
