# SENSITIVE DETECTORS
# GATE provides two sensitive detectors, which have two different functions
# Using them properly is very important for getting accurate results
 
# Crystal SD
# The crystal SD makes it possible to record hits in a sensitive volume ( e.g.,. in a scintillation crystal)
# It must be attached to any volume for which hit-data must be obtained
# For recording hits in the NaI volume only, the name of which is crystal, this volume is attached
# to the crystal SD

# Phantom SD
# The phantom SD makes it possible to record Compton events in the volumes within the field of view
# This can provide information for result analysis to discriminate between
# scattered and unscattered photons
# It must be attached to each and every volume for whom Compton interactions have to be recorded
