[Gate-users] Material image dose scoring

[Emmanuel Marfo]

Hello

Thanks for the quick response. Please, the images are density images obtained by dividing linear attenuation(energy information) values by mass attenuation(material basis).

Attached is a dropbox link of a folder containing the material decomposed images for your assessment. thanks

Hi Emmanuel,

When you said material decomposed image, are you talking about Rho/Z image (effective density and atomic number - image)?
What info do you have in your image?

Best regards
Maikol

Hello Gate Users,

Please, I need help on this or if anyone has the knowledge of how it can be done I would be grateful. I am using a spectral CT system to obtained material decomposed image based on mass attenuation and energy information. I want to do dose deposition on the material decomposed images without the use of Schneider material converter employed in GATE.  My problem is I want to know if GATE architecture supports it and second I can not import the material decomposed image into GATE because is always requesting for a conversion text file. Can I bypass it? Can someone help me, please? Thanks


Best regards,
