9.2.1  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(not 
available for M7T) 
The grayscale distribution of ultrasonic echo signals across a line. 
Color Velocity  Color flow velocity (only valid for Color mode). 
VF Diam 
Measures the distance between two points on the image to obtain 
the vessel flow diameter.

M general measurements refer to general measurements on M mode, Color M mode, 
Free Xros M mode images. The measurements listed below can be performed: 
Measurement 
Tools 
Function 
Distance  The vertical distance between two points. 
Time  The time interval between any two points. 
Slope 
Measures the distance and time between two points and calculates 
the slope.
