2D Soft menu controls
Compress
Controls the amount of contrast in the 2D image. An index
number is displayed in the status window to indicate the
relative level of compression.
Reject
Adjust reject level. When this control is increased, low-level
echoes are rejected and appear darker in the 2D image. An
index number is displayed in the status window to indicate the
relative level of rejection.
Dynamic Range
Enables control of the dynamic range or contrast of the image.
When dynamic range is set high, the image is softer and more
low-level data is visible.
Smart Depth
For every setting of scan-depth there is an optimal Frequency /
Transmit Pattern setting.
The Frequency/Transmit Pattern should be optimized to
produce both a clean signal, and maximal spatial resolution.
With Smart Depth turned ON, the system will optimize the
Frequency/Transmit Pattern to follow above guideline, and
automatically set optimal setting for the currently selected
depth.
The Frequency control value displayed on screen will be
modified to display the updated value with every change of
depth setting by the operator.
The operator may change the Frequency control at any time to
any desired Frequency/Transmit Pattern.
If the depth setting is changed anytime after the user has
manually modified the frequency, the system will attempt to
optimize the Frequency/Transmit Pattern, taking into account
the different frequency-preference as set by the manual
modification by the user.
With Smart Depth turned OFF, the Frequency control setting
will remain unchanged even when depth setting is changed.
