Remarks:
•
The maximum and minimum depth depend on the selected probe. The actual depth in
[cm] is displayed in the Information Header.
•
freeze mode: The displayed 2D image is positioned on the monitor again without change
in the depth range.
6.2.3 2D Image Angle
Use the [Angle] control to select a part of interest of the 2D image. The advantage of the
decreased field-of-view is an increased 2D frame rate due to the smaller sector width.
Turn the control clockwise to increase the image width. Τurn the control counterclockwise to
decrease the image width.
Remarks:
•
If the selected probe has the possibility to adjust the 2D angle, the display above the
digipot control will show its value.
•
Digipot display: curved array probe: Angle [degree]
6.2.4 TGC Slider Controls
The “TGC slide 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 gain (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 central position because of the preset time
gain compensation for each scanhead.
•
The slider setting is not stored in a user program, because of the absolute position of the
sliders.
