Hello,
I have 3D dose distribution of photon plans and would like to obtain fluence maps to deliver the dose using OpenTPS.
I believe this can be done by optimizing the plans with dose-mimicking.
Does OpenTPS support a dose-mimicking function, or are there ways to implement it using existing functions?
Thank you in advance!

Hi Leehoy,
Unfortunately we do not support dose mimicking. However, implementing a basic quadratic dose penalty cost function inside opentps/opentps_core/opentps/core/processing/planOptimization/objectives/dosimetricObjectives/ and a new optimizer in opentps/opentps_core/opentps/core/processing/planOptimization/ will do the trick without being too cumbersome. Just be aware that for now OpenTPS does not support MLCs; therefore mimicking your dose map might be impossible if you used one to generate it.
We remain available to help you if further needed,
Regards,
Eliot
Thank you for the clarification and suggestion. I will try that out.
