Automatic Measurements

All automatic measurements are proposed by the software. They can be reviewed and
edited by the user.
Automatic measurements are based on numerical models of anatomical structures which
are detected in the ultrasound data.

Data: 4D Data, 2D B-Mode
Comments: Distance = Distance between two points; Displacement = Distance between a
point at a reference time point and a time point t; Regional Strain = Relative length change
of a distance; Global Strain = Relative length change of a curved contour; Sphericity Index =
Distance ratio; Velocity = First derivative of displacement;
