[Gate-users] Energy spectrum in CT source example

[Hyun-Ju Ryu]

Hello,

I'm using virtual GATE v6.

In the CT source, x-ray energy spectrum was put as list of histpoint.

When i simulate x-ray spectrum using SRS78 or SpekCalc program, number of
photon at each energy point was calculated as decimal.

However CT source example put number of photon as integer.

Would you explain the calculation standard of CT source example or the
hidden information of CT source example?

ex) N[keV cm^2 mAs]^-1 @ 1 meter
Also, source activity value could be calculated by sum of number of photon?

Thank you.
Best regards,
Ryu.
