How to add two dicom dose .bnn files together？

Scoring
1

The RT Plan contains two BEAMs, each of which is recalculated in FLUKA to get a .bnn file of the dose distribution, and now I want to add up the two .bnn files from the two BEAMs to see what dose distribution was obtained for the whole plan. How do I add them up?

I have two BEAMs in two source files, maybe I can define two BEAM cards, and calculate the dose distribution of both BEAMs in one input file at the same time? If so, how to implement it?

Dear Jin,

  1. you can use the usbscw tool to manipulate (addition, multiplication) USRBIN results.

  2. Two BEAM cards won’t work, because the second one will overwrite the first. However, you can use the SPECSOUR card with the option BEAMSPOT to set up multiple beams in a single simulation.

Cheers,
David

Thank you very much for your reply！
But I didn’t find this tool in Flair GUI, where can I find the tool usbscw?

Dear Jin,

This is a command line tool located in the <FLUKA>/bin directory. You just need to type usbscw in a terminal to launch it.

Cheers,
David
