| 摘 要： | 采用代数重建算法处理由电容层析成像系统所采集的投影数据可以获得较高质量的图像，介其耗时较多。本文着重提出一种准则并以此优化迭代过程中投影的选取顺序，以提高代数重建算法的收敛速度，从而改善成像系统的整体性能。

| Abstract: | Algebraic reconstruction algorithm(ART) is used to process projections from electrical capacitance tomographic systems and to reconstruct high qualitative images, but it need more time.A rule is proposed and it is used as an optimistic criterion to select projection order during iteration. Hence the convergent speed of ART is increased.The whole performance of electrical capacitance tomographic systems is improved. |
