Switch Function
Used to select whether the 2D (CDI) mode image is displayed in
real time (
[2D REAL] ) or the M-mode or Doppler mode image is
displayed in real time ( [MD REAL] ), when Doppler mode is
entered from 2D (CDI) mode.
Used to select whether the Doppler scale is set to velocity ( [cm/s] )
or frequency ( [Hz] ).
Used to set high-velocity support mode to ON/OFF in 2D+PW
display mode.
(*)
Used to specify whether or not the color mode (CDI/Power/ADF)
steering operation and PW steering operation are to be performed
independently in oblique scan.
ON : Independent operation for CDI steering and PW steering.
OFF : Simultaneous operation for CDI steering and PW steering.
(*)
Used to invert the Doppler oblique scan angle. When this switch
is pressed while the Doppler oblique scan angle is set to an angle
other than 0°, the oblique scan angle is inverted.
(*)
Used to select whether the ±10° PW steering angle setting is
skipped when
[Indep. Steer] is set to ON. The linear transducer
can normally be set to a maximum PW oblique scan angle of ±30°
in increments of ±10°.
ON : PW steering angle settings 0°, ±20°, ±30°
OFF : PW steering angle settings 0°, ±10°, ±20°, ±30°
(*)
Used to reverse the velocity direction automatically according to
the angle of CDI or Doppler steering.
Specify whether or not the steering direction relative to the center
(from right to left or from left to right), the color velocity range, the
Doppler velocity range, and the Doppler Angle Corr. mark are
reversed when steering is performed for the Color ROI or
sampling marker using the linear transducer with
[Indep. Steer]
set to ON.
The selection menu is as follows:
[Off] : Even if the steering direction is reversed, the
velocity ranges and the Doppler Angle Corr.
mark are not inverted.
[COL & Angle] : If the steering direction is reversed, the color ROI
and the Doppler Angle Corr. mark are inverted.
[PW & Angle] : If the steering direction is reversed, the sampling
marker (PWD) and the Doppler Angle Corr.
mark are inverted.
[ALL] : If the steering direction is reversed, the color
ROI, the sampling marker, and the Doppler
Angle Corr. mark are inverted.
[Angle only] : If the steering direction is reversed, the Doppler
Angle Corr. mark is inverted.
Used to select the display type for Doppler auto trace line.
[PEAK] : Only the peak velocity trace is displayed.
[MEAN] : Both the peak velocity trace and the mean velocity
trace are displayed.
