List of breast-mass-related DEVICE measurements. These measurements can be accessed only after a breast mass has been identified and marked.

DEVICE Metrics	Description	Controllable
T3DDN	Target center point 3D distance to nipple $\left|OT\right|$	No
T2DDN	Target center point distance to nipple projected in xy plane (2D) $\left|O{T}^{\prime }\right|$	No
T_ratio	Ratio between target 3DDN and target 2DDN	No
T_CFP	Target clockface position, i.e., angle $\widehat{T^{\prime }ON}$	No
T_height	Distance from target center point to nipple in z-axis $\left|T{T}^{\prime }\right|$	No
T_skin	Distance between target center point and skin $\left|PT\right|$	No
T_chest	Distance between target center point and chest surface $\left|TC\right|$	No
T_skin_chest_ratio	Ratio between target to skin and target to chest	No
T_diameter	Target’s longest diameter as measured on the ultrasound image	No
T_volume	Target’s volume measured using an ellipsoid fitting on the 3 main axes	No
