  1. The narrow fan - beams are reset into parallel beam then the image reconstruction is conducted by parallel beam " convolution back projection algorithm, which combines the high scan efficiency with the convenience of image reconstruction. this paper analyses the parallelism in narrow fan - beam " convolution back projection algorithm, divides the task of image reconstruction into several subtasks, and discusses the parallelization of narrow fan - beam " decomposition and reset, parallel beam " convolution back projection, and image accumulation

    對于窄角扇束掃描方式，把窄角扇束重排成平行束，再由平行束卷積反投影重建演算法來重建圖像，是把掃描的高效率和重建方式的簡便易行很好的結合起來。本論文對窄角扇束卷積反投影演算法進行了并行性分析，指出把圖像重建任務分解為多個子任務并行工作，並在工作站機群上討論了窄角扇束的分解、重排、平行束卷積反投影圖像重建、圖像合成的并行實現。
  2. How improving the capability of ict has become more and more an important task, for example, improving spatial resolution and density resolution, reducing scan time, enlarging the size of measure space, improving image quality, etc. moreover the question of the energy spectrum hardening and the photon scattering is one of important bottleneck to restrict the improvement of ict

    如何提高工業ct的性能指標，如怎樣進一步提高空間解析度、密度解析度，減少掃描時間，增大可測工件尺寸，改善圖像質量等等成為了ct界面臨的重要任務。而其中射線的能譜硬化和散射問題，又是制約工業ct各項性能指標提高的重要瓶頸之一。
