2D Mode
5.4 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 it to adjust the sensitivity (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 actual gain value is displayed on the screen [GN ...] )
* To change the 2D Gain is only possible with 2D mode (Single, Dual, Quad) on and real time
mode (write mode) active (independent of additional modes such as CFM or PW...)
5.5 TGC Slider Controls
The “TGC slider controls” vary the gain in certain depths of the 2D image to allow an exact
compensation for the attenuation of the echoes over time (depth).
TGC slide controls to selectively adjust the sensitivity (brightness) in depth
Slide a slide control to the left to decrease the gain in the corresponding specific
2D depth.
Slide a slide control to the right to increase the gain in the corresponding specific
2D depth.
Remarks:
* The standard adjustment of the sliders is the middle position because of the preset time gain
compensation for each scanhead.
* The setting of the sliders is not stored in an user program, because of the absolute position
of the sliders.
