8.2 General Measurements
8.2.1 2D General Measurements
2D general measurements are general measurements on images in 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
Measures the distance between the probe surface and the probing point
along the ultrasound beam.
Angle Measures the angle between two intersecting planes.
Area Measures the area and perimeter of a closed region.
Volume Measures the volume of a target.
Double Dist.
Measures the length of two line segments which are perpendicular to each
other.
Parallel Measures the distances between each pair of parallel lines in a sequence.
Trace Length Measures the length of a curve.
Distance Ratio Measures the lengths of any two lines and calculates the ratio.
Area Ratio Measures the areas of any two regions and calculates the ratio.
B histogram
Measures the grayscale distribution of ultrasonic echo signals in a closed
region.
B profile Measures the grayscale distribution of ultrasonic echo signals across a line.
Color Velocity Measures the color flow-velocity (only in Color mode).
Volume Flow Measures the blood flow through a vascular cross section per unit time.
Strain Ratio Measures the strain ratio in the image.
Elasto ratio Measure the elastography ratio
Strain-Hist Displays the strain ratio using the histogram.
Elasto-Hist Display the elasto value of the ROI in a histogram
IMT Measure intima-media thickness
8.2.2 M General Measurements
M general measurements are general measurements on M-mode, CM-mode and AM-mode
images. The measurements listed below can be performed:
Measurement
Tools
Function
Distance Measures the vertical distance between two points.
Time Measures the time interval between any two points.
Slope
Measures the distance and time between two points and calculates the
slope.
