[Gate-users] Activity ~ mAs

[Järvinen Jukka Ilari]

Hi,
 
I'm interested in simulating CT-dose and have modelled my system and phantom (attempted to import interfile multiple times using multiple programs, but to no avail). Currently I'm a little bit puzzled as to how to correctly use activity in case of a CT. 
 
The classic example had a preset value of 350000 Bq and so far I have approximated my system to require activity between 10 to 100 times that. I also read that I can input dose in Gy in the activity. Which dose exactly should I input to the system? Is there a way to take into account the mAs-value of a CT?
 
Best regards,
Jukka
