  1. On the basis of investigation and research about the technology of reconstruction for ict image up - to - date, this paper is devoted to develop an algorithm for image reconstruction based on wavelet theory. in this paper, time - frequency distribution for spatially varying filter was used to construct convolve - kernel by dwt, to modify convolve - back - projection algorithm

    本文在國內外有關ct圖像重建的研究狀況基礎上，根據小波分析理論，利用小波變換在時頻空間的可變性，用dwt變換構造卷積核，對卷積反投影演算法做了改進。
  2. The image reconstruction algorithms is thoroughly researched. the filter back projection ( fbp ), algebra reconstruction technology ( art ) and fan beam data rearrangement algorithm used in medical computer tomography are improved. the noser algorithm, linear neural networks method and hopfield neural networks method are presented and gain the better result of image reconstruction

    深入研究了圖像重建演算法，改進了醫學ct的濾波反投影演算法、代數重建技術和扇束投影數據重排方法，提出了帶圖像光滑約束的noser演算法、線性神經網路方法和hopfield神經網路方法，並得到了較好的圖像重建結果。
  3. The image of computed tomography ( ct ) is of good quality and high resolution. it can be processed and analyzed digitally therefore, ct has become a new nondestructive detection technique, which is applied widely in aviation, shipping, automobile, public security and other areas. the filter back - projection ( fbp ) technique and the algebraic reconstruction

    =計算機層析成像（簡稱ct ）技術檢測精度高、重建的圖像具有無影像重疊、空間解析度和密度解析度高、可以直接數字化處理與分析等特點，成為近十幾年發展起來的一種新的無損檢測技術，廣泛應用於航空、航天、機械、船舶、公安、海關等諸多領域。
