Hi,

I hope this message finds you well.

I am using the SlicerRT project in my research on Monte Carlo dose calculation in anthropomorphic phantoms, and I am particularly interested in the dataset **eclipse-8.1.20-phantom-breast** ([link](https://github.com/SlicerRt/SlicerRtData/tree/master/eclipse-8.1.20-phantom-breast)).

Could you share some details on how this dose was calculated? Specifically:

- Which dose calculation algorithm was used (AAA or Pencil Beam Convolution)?
- Was heterogeneity correction enabled, and if so, which method (e.g., for PBC: Batho, modified Batho, or equivalent TAR)?
- If available, could you also share the CT calibration curve (HU to relative electron density) that was used for the dose calculation?

I would like to compare my Monte Carlo results with this plan, so this information would be very helpful.

Best regards,
