Description
Distance(mm)
Measures the distance between two points on the image.
Depth
The distance between transducer surface and the probing point along ultrasound
beam.
Angle
The angle between two intersected planes.
Area (Ellipse, Trace,
Cross, Spline)
Measures the area and perimeter of a closed region.
Volume (Ellipse),
Volume (Ellipse
distance)
The volume of a target.
Double dist
Measures the length of two line segments perpendicular to each other.
Parallel Line
Measures the distance between every two line segments of five parallel line
segments, namely, four distances in total.
Trace length, Spline
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
Measures and counts the gray distribution of ultrasonic echo signals within a
closed region.
B profile
Measures the gray distribution of ultrasonic echo signals on 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.
Strain Ratio
Measures the strain ratio.
Elasto ratio
Measure the elastography ratio
Anisotropic elasto
ratio
Measure the anisotropic elasto ratio
Strain-Hist
Display the strain value of the ROI in a histogram.
Elasto-Hist
Display the elasto value of the ROI in a histogram
IMT
Measure intima-media thickness
