8.2 General Measurements
8.2.1 2D General Measurements
2D general measurements refer to general measurements on images of B, Color, Power
or iScape imaging modes. The measurements listed below can be performed:
Measurement
Tools
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
Measures the lengths of any two line segments and the calculated
ratio.
Area Ratio The areas of any two regions and the calculated ratio.
B histogram
The grayscale distribution of ultrasonic echo signals in a closed
region.
B profile The grayscale distribution of ultrasonic echo signals across a line.
Color Velocity Color flow velocity (only valid for Color mode).
Volume Flow
Measures blood flow through some vascular cross section per unit
time.
Color Velocity
Profile
Detects velocity profile as well as diameter of the maximum
diameter vessel to get blood flow volume per unit time.
Strain-Hist (Option)
Displays the strain ratio using the histogram, strain ratio = strain
(normal tissue)/strain (lesion).
