The Harmonic control invokes and exits harmonic imaging.
While in harmonic imaging the control is highlighted and an
„H‟ is displayed in the B-mode frequency field. Depending on
the transducer, there may be multiple harmonic frequencies.
Spatial Compounding combines images derived from
multiple angles to reduce speckle, reduce shadow artifacts,
and enhance contrast resolution. Spatial compounding is an
on/off control.
Focus Number adjusts the number of foci is displayed. As
the number of foci increases, image uniformity across depth
will increase, but the frame rate will decrease.
Focus Position adjusts the depth of the focus or foci. Upward
presses move the focus shallower, regardless of the U/D
invert status of the image.
Gray Map adjusts the postprocessing map used on the
B-mode image. In general, higher map numbers correspond
to more contrast in the image.
The Colorize control adds a color tint to the B-mode image.
The Tint control changes the color tint being used. There are
20 tint maps available. If Colorize had been off, changing the
Color map control will automatically activate it.
The Left/Right invert control is indicated by a backward R
and is used to toggle the left/right orientation of the image.
The Edan E orientation marker at the top of the image
switches with the left/right invert to match the orientation
marker on the transducer.
The Up/Down invert control is indicated by an upside-down
R and is used to toggle the up/down orientation of the image.
The TGC curve is also re-oriented with Invert On, so that the
top of the TGC curve corresponds to the top of the image on
the screen.
