5.1 Conventional measure
5.1.1 2D Conventional measure
2D conventional measurements are suitable for regular measurements of 2D images such as B,
Color, Power and so on. The items of measurement are as follows:
Measure item
Function
Distance
Measure the distance between two points on an ultrasonic image.
Angle
Measured the angle between the two intersecting planes on the ultrasonic
image.
Area
Measure the area and perimeter of an enclosed area on an ultrasonic
image.
Three distance
volume
Measure the volume of the target object.
Recording length
Measure the length of a curve on an ultrasonic image.
Recording area
Measure the area and perimeter of a closed curve area on the ultrasound
image.
Length ratio
Measure the length of the two lines on the ultrasonic image and calculate
the ratio.
Area ratio
Measure the area of two enclosed areas on ultrasonic images and
calculate the ratio.
Histogram
Measure the gray distribution of ultrasonic echo signal in a closed area of
ultrasonic image.
5.1.2 Conventional measure in M mode
M mode measurements are as follows:
Measure item
Function
Distance
Measure the distance between any two points on a vertical line at a given
time.
Time
Measure the time interval between two points on the M image.
Gradient
The average slope between two points is calculated by measuring the
distance and time of the two points.
Heart rate
On M cardiogram, the interval between two cardiac cycles was measured
and the heart rate was calculated.
