摘要
第八届三维图像重建及核医疗学国际会议于2005年7月在美国盐湖城召开。该会议是在CT、PET 及SPECT 图像重建领域最负盛名的会议之一。本文主要介绍在本次会议上提出的几种最新锥束CT 精确重建算法,包括MD-FBP 算法、R-line 算法等;还讨论了这两种精确锥束重建算法的各自优点,并对CT图像重建领域下一步的研究方向做了展望。
The intemational meeting on fully three-dimensional image reconstruction meeting in radiology and nuclear medicine was hold in July 2005, USA. It is one of the most fan.us meetings in CT, PET and SPECT image reconstruction field This paper introduces some novel developments in PET, SPECT and CT imaging upon lifts meeting. According to our interest, we focus on exact conebeam CT reconstruction including Minimum data filtered-backprojection algorithm （MD-FBP）, the R-line algorithrn and so on. In the end, we discuss the different advantages of the above two exact algorithms and research prospects in conebeam reconstruction
