[Castor-users] Attenuation correction using .hdr format?

[Ashok Tiwari]

Dear CASToR users,

I’ve generated an attenuation map of the phantom using DICOM images (CT) in MATLAB. I managed to save the linear attenuation coefficients (cm^-1) in interfile (.hdr header and .img data) format. Then, I fed these files in castor reconstruction using ‘-atn atten_map.hdr’ command. But I could not able to perform the attenuation correction correctly. Attached is the screenshot of errors that generated during the reconstruction. Do I have to convert the attenuation map data in castor file format?

Any help will be appreciated. Thank you.

Regards,
Ashok
