The PW key is used for activating the Pulsed Wave Doppler (PW), CW for
activating the Continuous Wave Doppler (CW); both keys activate the positioning
cursor if necessary. As in M-Mode, there are five viewing formats: the three split
formats, the dual format and the full screen format.
TV Mode In PW, the buttons on the touchscreen allows the operator to switch to Tissue
Velocity (TV) mode. TV sets Doppler filters to display the strong signals with low
motion such as the heart walls motion, rather than flow. TV mode is available with
specific probes.
During the exam, the format can be preset or varied interactively through the
menu.
In 2D or CFM, the cursor can be interactively activated or disabled to select the M-
Mode or Doppler line (taste
LINE UPDATE ). When a trace is active, the same key
freezes the trace acquisition and reactivates the 2D reference.
The AUTO keys, available both in B-Mode and Doppler, automatically adjusts
some controls of the active mode to make the echo acquisition easier.
The touchwheel around the Auto button, on the left side of the panel acts on B-,
M-Mode CFM, Power Doppler and Doppler signals, adjusting amplification over
the entire depth of the image.
To increase gain, scroll clockwise, to reduce it, scroll counter-clockwise.
In Doppler modes, gain acts on the video component of the signal. The level of
the audio signal can be independently adjusted with the
AU DI O
rotating knob.
The NEARFIELD & FARFIELD GAIN buttons adjust the gain in the near or far field
of the image. Left side will reduce the gain while the right side will increase the gain.
This key stops the current analysis or scan and puts the system in Freeze mode. To
re-activate real time, press
FREEZE a second time or directly press the key of the
required mode.
Multiformat Controls
Depending on system presets or on the active selections on the displayed menu,
these keys activate multiple views of two (dual) images both in real time and in
freeze.
