Frequency
On some low fre-
quencies, the sys-
tem switches
automatically to
second-harmonic
mode. The word
“Octave” appears
in the status win-
dow.
Enables the adjustment of the probe's operating frequency.
The selected frequency is displayed in the status window. For
some probes/applications the lowest frequency settings will be
Octave imaging settings.
Note
: While changing the Frequency value on display, the
operator actually selects different transmit patterns associated
with that value, which includes transmit pulse shape, frequency
and transmit sequence.
Octave
Enables quick switching over between Octave imaging and
corresponding fundamental frequencies, without rotating the
Frequency selection rotary knob.
Invert
•
Left/Right Invert
: enables a mirror image of the 2D image
to be created. The left/right reference marker
V
moves to
the other side of the image.
•
Up/Down Invert
: enables the 2D image to be flipped
180 degrees.
Dual focus
Activates Dual focus mode (optionally available in cardiology
applications only). To adjust the location of the Dual focus,
activate the
FOCUS
assignable.
B Color maps
Displays a color map menu to optimize the greyscale
presentation. The menu enables an option from a list of
non-linear gray-curves or different 2D-colorized curves to be
selected. Use the assignable rotary knob to highlight and
activate the desired map.
Compound
Compound is a process of combining three frames from
different steering angles into a single frame. The combined
single image has the benefits of reduced speckle noise,
reduced clutter, and continuity of specular reflectors. Therefore,
this technique can improve contrast resolution.
