Is there a standard way to extract the features (body composition, bone density, ...) of DXA images?

Hi RG,

I want to get features of DXA images (e.g. legs lean mass) that generate using the device, but I need to do it manually. Is there a standard way to extract them or we have to train a model for it based on prepared targets?
