2D Gain
2D When rotated clockwise, increases the overall gain applied to the received echo
signals equally for all depth.
Time Gain Compensation TGC
2D Compensates for depth-related attenuation in an image. The sliders nearest the
operator affect the far field. TGC amplifies returning signals to correct for the
attenuation caused by tissue at increasing depths.
Auto
2D Turns Auto Tissue setting on/off (see ‘Auto Tissue’ on
page 5-51
).
Depth
2D Sets the maximum (far field) distance that will be imaged. Decreasing the depth
may allow higher frame rates.
Line Density
2D (non-cardiac) Controls the spatial resolution of the image versus the image update rate.
HD (High Definition)
2D Smoothens the speckle and reduces the noise in the image.
Width/2D width
2D, CF, TVI, TT, SRI,
SI, TSI Controls the size or angular width of the 2D image. A smaller angle generally
produces an image with a higher frame rate.
