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
The length of two line segments, which are perpendicular to each
other.
Parallel
The distance between each pair of parallel lines in a sequence.
Trace Length
Measures the length of a curve on the image.
Double Dist
Measures the length of two line segments, which are
perpendicular to each other.
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
Blood flow through some vascular cross section per unit time.
IMT
Measures the distance between LI (Lumen-Intima) and MA
(Media-Adventia).
Volume
Measures the volume of the target object.
