[Castor-users] CASToR Binary Datafile

[tmerlin]

Hello Reza,

Please see section 6.1 of the general documentation pdf to have a 
description of the mandatory/optional fields for the PET header and 
binary datafiles. The position of the line of response in your one 
coincidence example will be defined by the crystal ID1 and ID2 fields, 
which will be associated to the crystal ID look-up-table as created for 
your scanner.

Additionally, you can have a look at the datafiles provided in the 
benchmarks distributed on the website, or the 
/castor-datafileConversionEx /script in the toolkits directory, which 
provides indications regarding how to implement some script to generate 
a PET CASToR datafile from any system datafile.

Regards,

Thibaut
