I want to do image reconstruction but I don't have the skill about image reconstruction of multi- pinhole collimator. I have done image reconstruction for the parallel hole with STIR. I think that STIR software is limited for image reconstruction of multi- pinhole collimator. I'm a beginner in image reconstruction. What software is suggested for image reconstruction of multiple pinhole collimator (CASTOR, STIR, MATLAB,...)?<o:p></o:p></p><p class=MsoNormal>I will be so pleased if anyone can guide me.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Thanks and Regads<o:p></o:p></p><p class=MsoNormal>Maryam Saed <o:p></o:p></p></div></body></html>
