[Gate-users] Reconstruction image by using MATLAB

[Ville-Veikko Wettenhovi]

Hi,


I have no experience with SPECT, only PET, so I can't give you exact details or code, but the main issues should be the same. You can import GATE ASCII files into Matlab with the dlmread command. This will make a matrix of the ASCII file. After that you need to collect all the events from the same detector (accumarray can be helpful). Then you either form an observation vector or a sinogram and use that in whatever algorithm you wish to test.


Hopefully that will help. As I mentioned above, I've done this with ASCII PET data and have working Matlab codes for that, but they aren't compatible with SPECT data.


Regards,

Ville-Veikko

Hi dear GATE users.

I simulated a SPECT camera. How can I use ASCII output of GATE  simulation and reconstruct it by MATLAB.

What commands should be used?



Best regards
