◆
Measure the histogram by ellipse or trace method: The method is the same as that to measure ellipse or
trace method, press [
UPDATE
] to change the measurement between ellipse and trace.
The horizontal axis represents the gray scale of the image ranging from 0 to 255.
The vertical axis represents the distribution ratio of each gray scale. The value shown on the top of vertical
axis represents the percentage of the maximally distributed gray in the whole gray distribution.

Cross-section Diagram
Cross-section Diagram is used to measure the gray distribution of the ultrasound signals in the vertical or
horizontal direction on a certain profile (section).
This measurement is only available in the frozen mode.
Measurement steps:
1.Press [
Calc
] to enter into measurement, press [
Change
] to switch measurement menu to [
General
]
measurement.
2.Press [
ENTER
] on [
Profile
] menu to enter into measurement status.
3.Draw a straight line at the measuring position. The method is the same as that to measure distance.
4.The calculated result of the profile will be displayed at the center of the screen.
1-The horizontal (or vertical) axis represents the projection of the profile line on the horizontal direction.
2-The vertical (or horizontal) axis represents the gray distribution of the corresponding points on the profile
line. The range is 0 to 255.
