[Castor-users] Collimator resolution

[Michael Ljungberg]

Hi Thibaut

Yes – I have read about this in the manual but since I am an old Fortran guy and not so experienced in C I took a first easy step.

By the way, would it be possible to add the output file name as a patient name in the output interfile in the next release? 

Hälsningar / Best regards
 
Michael

    Dear Michael,
    
    Up to now, I haven't heard/read of anyone who did such a translation.
    
    I just wanted to point out that there is the possibility to implement a 
    custom collimator model in the code. The model has to be defined as 
    "custom" in the geom file, and the implementation could be made in the 
    src/scanner/iScannerSPECTConv.cc file, inside the 
    ComputeFocalPositions() function (around lines 840 and 916 to compute 
    the axial and transaxial focal points respectively). From there, the 
    parameters of the model can be accessed.
    
    This feature lacks some flexibility for the moment, but we'll work at 
    making it more practical and modular as some other Castor features.
    
    Kind regards,
    
    Thibaut
