- 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
該系統(tǒng)采用32體表電極進(jìn)行阻抗測(cè)量，用加權(quán)反投影算法進(jìn)行圖象重構(gòu)。 - 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
根據(jù)這一投影重建理論，導(dǎo)出了impsar目標(biāo)投影重建的卷積-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
經(jīng)過理論分析和數(shù)值仿真，本文提出的基于可分離mra去噪小波重建算法、基于不可分離mra的小波重建算法和基于不可分離mar的去噪小波重建算法，都有一定的創(chuàng)新性和實(shí)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
這種算法具有局部重建特性，從而降低了x射線的輻射劑量和算法的運(yùn)行時(shí)間，在保證和傳統(tǒng)的濾波反投影法具有基本相同的圖像重建質(zhì)量的條件下還具有一定的去噪性能。
