Controls Affecting Acoustic Output
The potential for producing mechanical bioeffects (MI) or
thermal bioeffects (TI) can be influenced by certain controls.
Direct. The Acoustic Output control has the most significant
effect on Acoustic Output.
Indirect. Indirect effects may occur when adjusting controls.
Controls that can influence MI and TI are detailed under the
Bioeffects portion of each control in the Optimizing the Image
chapter.
Always observe the Acoustic Output display for possible effects.
Best practices while scanning
NOTE: Refer to the sections of the Optimizing the Image chapter for a
complete discussion of each control.
Acoustic Output Default Levels
In order to assure that an exam does not start at a high output
level, the LOGIQ 7 initiates scanning at a reduced default output
level. This reduced level is preset programmable and depends
upon the exam category and probe selected. It takes effect
when the system is powered on or
New Patient is selected.
HINTS
Raise the Acoustic Output only after attempting image
optimization with controls that have no effect on Acoustic
Output, such as Gain and TGC.
WARNING
Be sure to have read and understood control explanations for
each mode used before attempting to adjust the Acoustic
Output control or any control that can effect Acoustic Output.
Acoustic
Output
Hazard
Use the minimum necessary acoustic output to get the best diagnostic image
or measurement during an examination. Begin the exam with the probe that
provides an optimum focal depth and penetration.
