摘要
基于Shear-Warp算法提出一种改进的体绘制算法·在对传递函数进行预设定时,基于边界模型并结合交互式操作,可以方便地设定最优传递函数值·在重采样过程中,结合Shear-Warp算法的特点对传递函数值进行修正,以保证重建后的图像质量·实验结果证明:该算法不仅效率高,而且显示效果好·
An improved volume rendering algorithm called ISWA, based on Shear-Warp method, is proposed in this paper. It is convenient and meaningful to pre-specify the transfer function for volume rendering based on the boundary model and interactive operation. In addition, to improve the reconstruction effect of medical images, the parameters of the transfer functions are corrected during the re-sampling process using the intermediate slice interpolation method. Experiments demonstrate the good performance of the proposed method.
