Attenuation correction

Hi All,

I am passing an attenuation image with the option –atn to castor-recon for a histogram format data, but the output is the same (the images are not attenuation corrected) whether I include the attenuation option or not. Any advice?

Thanks,

Sadek

Hi Sadek,

We did not implemented yet having an attenuation map with histogram reconstructions.

This option is only valid for list-mode.

Attenuation should be directly embedded into the histogram datafile.

Sorry for the delayed answer.
