Table 5.4 Recommended Image Optimization Sequence
Select the appropriate procedural
setting from the procedural toolbar.
Select the depth required to
see the target structure.
Adjust focus to align with
the target structure.
Adjust frequency according
to the target depth.
Adjust Gain and/or TGC
to user preference.
Start from a known optimized image.
Visualize target depth/structure to start optimizing image.
The focal point on the image has the best image resolution.
Higher frequency has the best resolution and should be used for shallow imaging.
Lower frequency has the best penetration and should be used for deep imaging.
Gain adjusts overall image brightness.
TGC adjusts brightness in sections of the image.
Adjust Contrast to user preference
and procedural need.
Adjust power.
Save as user preset.
High contrast is black and white.
Low contrast is many shades of gray.
Higher power makes the image brighter.
Once the image is adjusted, the clinician may want to save these custom
settings for future use.
STEP
Note: All steps may not be required to optimize the image.
Note: Depth, Focus, Frequency, and Power affect the acoustic output and the MI (Mechanical Index) and TI (Thermal Index) values.
The MI and TI values should be monitored as these parameters are adjusted so that the lowest values of MI and TI are used that
achieve the desired image. See the Site~Rite Vision* Ultrasound System instructions for use for further information regarding MI, TI
and prudent use.
