Values
The list of available depth values depends on the type of probe used. Measurement units used -
millimeters (mm). The painted depth scale on the ultrasound image displays tick marks at 10 mm intervals.
Adjustment
Click “Depth” button and do sweeps on ultrasound image.
Relations to other controls
After adjusting the Depth you may need to adjust the Gain, TGC (Time Gain Compensation) and the
Focus controls.
Smaller scanning depths usually allow you to achieve higher frame rates (FPS - Frames Per Scond).
7.1.3. Dynamic Range
Description
Dynamic range is a measure of the ultrasonic device's ability to display both very weak and very
strong signals at the same time while ensuring their levels can still be visually distinguished. The greater the
dynamic range the better the above-mentioned ability. As a rule, every observation should be started using
the maximum possible dynamic range since it provides you with the most complete diagnostic information.
Narrowing or reducing the dynamic range leads to the echo image displaying more contrast. Dynamic Range
is useful for optimizing tissue texture for different anatomical structures.
Values
The values available depend on the type of probe used. Measurement units used - decibels (dB).
Adjustment
Click “Dynamic Range” button and do sweeps on ultrasound image.
Hints
Adjust the Dynamic Range so that the highest amplitude edges appear as white while the lowest
levels (such as for blood) are only just visible.
7.1.4. Power
Description
Power adjustment increases or decreases the acoustic power of the transmitted ultrasound signal.
Larger power values allow you to increase the penetration depth and can help to achieve better image
quality when observing tissues at greater depths.
Values
Available power values usually are in the interval [-20;0] dB. Measurement units used - decibels (dB).
Adjustment
Click “Power” button and do sweeps on ultrasound image.
