Dear all, I am using the SARTConeBeamReconstructionFilter recently and it works well. Thanks for providing this helpful toolkits. I got one question when using this filter that there is one parameter called ‘m_NumberOfProjectionsPerSubset’. On your website(http://www.openrtk.org/Doxygen/classrtk_1_1SARTConeBeamReconstructionFilter.html), the description for it is Number of projections processed before the volume is updated (1 for SART, several for OS-SART, all for SIRT).
According to my knowledge, if we update the volume each time when one projection was processed, shouldn’t it be ART algorithm? And all projections represents SART, several represents OS-SART. So I got confused about the description and how SIRT was introduced here. Could anyone please give me some hints on how should I understand this? Thanks in advance. Best regards, Zhehao
