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 
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.
