[Gate-users] Track length within a volume

[Nils Krah]

Hi Andreas,
I cannot share any first hand experience with the examples you provided. Maybe these publications help:
https://hal.archives-ouvertes.fr/hal-01015846
https://hal.archives-ouvertes.fr/hal-01912041
(if you do not know them already anyhow).

Some of the authors are part of the Gate collaboration, so maybe they can provide more insight.

Cheers,
Nils

I tried to attach the actor to the volume I want to measure the track length within (pixel), and then I add a particle filter for protons since I only want to know the track length of protons within the pixel volume. The script I have used below does not seem to give me the track length of protons inside the pixel volume, it seems to give the entire track lengths of protons in the simulation. Is it possible to do what I want?
