backprojection algorithm meaning in Chinese
向后投射算法
Examples
- The system makes impedance measurements using an array of 32 electrodes on the surface of the body , and reconstructs the images using a veighted backprojection algorithm
该系统采用32体表电极进行阻抗测量，用加权反投影算法进行图象重构。 - The corresponding image formation algorithms , both in tune domain and frequency domain , are introduced . beginning with the projection reconstruction theory , convolution - backprojection and its approximated algorithm , backprojection algorithm are given
根据这一投影重建理论，导出了impsar目标投影重建的卷积-反投影算法及其近似算法-反向投影算法。 - And so the method whichhas the same quality as filtered backprojection algorithm , used the properties of wavelet to reconstruct a local region of the cross section of a body , using almost completely local data , and could reduce noise of the image
经过理论分析和数值仿真，本文提出的基于可分离mra去噪小波重建算法、基于不可分离mra的小波重建算法和基于不可分离mar的去噪小波重建算法，都有一定的创新性和实用性。 - This algorithm not only have the charicristic of local reconstruction that could reduce the amount of x - ray exposure and computations in reconstruction , but could reduce the noise in the conditions of keep same image quality as reconstructed in the filter - backprojection algorithm as well
这种算法具有局部重建特性，从而降低了x射线的辐射剂量和算法的运行时间，在保证和传统的滤波反投影法具有基本相同的图像重建质量的条件下还具有一定的去噪性能。
