[Gate-users] How to model kinetics of different ROIs

[dimitris]

Hi Sara,

the only way you can do that at the moment with the current release is 
by simply launching multiple simulations at different time points of 
your TAC.

We have already created the necessary classes that will do that in a 
real fashion for both physiological motion on the voxellised phantoms 
and TACs at different organs or ROIs. This work was presented in the 
IEEE MIC meeting last year (see proceedings paper attached) and it is 
currently undergoing further validation. Although the paper describes 
the implementation with the NCAT phantom it is equally possible to do 
that with any 4D patient datasets. It will be part of one of the future 
releases of GATE but at this point it has not been fixed. In the 
meantime if you have specific applications in mind you may want to take 
part in our validation studies.

Best regards

Dimitris
