Function
Distance Measures the distance between two points of interest.
Depth
The distance between probe surface and the probing point along
ultrasound beam.
Angle The angle between two intersected planes.
Area Measures the area and perimeter of a closed region.
Volume The volume of a target.
Cross Line
The length of two line segments, which are perpendicular to each
other.
Parallel Line The distance between each pair of parallel lines in a sequence.
Trace Length Measures the length of a curve on the image.
Distance Ratio
