Dear Castor Dev,

I need to forward-project SPECT images and save them in histogram format. I am wondering if there is any piece of code for that?

_Met vriendelijke groet, kind regards,_

Dear all,

I would also appreciate it if I can get one such forward-project code too. Thank you very much!

Best regards,

Dear Esmaeel Jafargholi and Zekun,

There is a rudimentary tool to perform forward projection from an interfile image and store it as a (CASToR) histogram. I will email it to both of you.

Best regards,
