6.2.1 2D Gain
With the “Gain” control the overall brightness of the 2D image is adjusted. The adjustment of
the gain control determines the amount of amplification applied to the received echoes. All
incoming echoes are amplified with the same gain value regardless of depth.
[2D Mode] key Rotate this key to adjust the gain (brightness) of the entire image.
When the GAIN control is turned clockwise the entire image becomes brighter. When the
GAIN control is turned counterclockwise the entire image becomes less bright.
Remarks:
•
The current gain value is displayed on the screen [GN ...].
•
To change the 2D Gain is possible with 2D Mode (Single, Dual, Quad) on and real time
mode (scan mode) active (independently of additional modes like CF or PW and also
possible with 2D Mode frozen)
6.2.2 2D Mode Depth
When the [Depth] control is flipped downwards, the depth range of the 2D image is enlarged
and the display size of the image is reduced to display the entire depth range. When the
[Depth] control is flipped upwards, the depth range of the 2D image is reduced and the
display size of the image is magnified.
With this function the depth range of the ultrasound image for the region of interest is adjusted.
The number of image lines and the frame rate are automatically optimized. Changing the
depth is only possible in real time (scan mode).
When you change the Depth, the 2D image display, the depth scale, acoustic power indices
(MI, TIS, TIB, TIC), frame rate, and focal depth will change accordingly.
