 **Classification of Liver Segments**
-By departing from the standardized Couinaud classification of the liver in segments, the implemented approach enables a more individualized representation of liver segmental distribution [@{d'Albenzio:2023}] \autoref{fig:couinaud_segments}. Particularly noteworthy is the method’s estimation of segments 8 and 5, resulting in a classification that is more applicable to real-world surgical scenarios, as shown in \autoref(fig:couinaud_segments.svg)[@Bismuth:1982].  While improvements, particularly in automating the landmark marking process, are needed, the approach holds promise for improving liver surgery planning and has the potential to optimize surgical outcomes.
