Brain Imaging Generation with Latent Diffusion Models - Brain volume measure

[andreaboscutti]

Hi,
Thank you for the amazing work on generative models.
I have a question regarding the generative model for Brain Imaging generation by @Warvito (https://github.com/Warvito/generative_brain). In the paper (https://arxiv.org/abs/2209.07162), what is "Brain volume" referring to? Assuming the Freesurfer output was used, could you please clarify on which of these three measures was used for "Brain volume" (see link: https://www.freesurfer.net/fswiki/BrainVolume):

• BrainSegNotVent
• BrainMask/BrainMaskNVox
• BrainSeg/BrainSegVol

Thank you,

Andrea
