61
The horizontal axis represents the gray scale of the image ranging from 0 to 250.
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.
6.2.5 Profile
Profile 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.
