• Segmentation possible due to 3D quantitative accuracy
• 3D algorithm – necessity of 3D model of field
• Proximity to the chest wall with 3D modelling of field
• Retromammary fat – glandular interface
• Retromammary fat – pectoralis interface
• “Distribution of cancers in the breast is uneven with clusters
in the posterior tissue region – the retromammary fat
glandular interface is an important area for cancer”
