Control elements that affect the acoustic output
The potential for producing mechanical bioeffects (MI) or thermal bioeffects (TI) can be influenced by certain control ele-
ments.
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
bioeffect portion of each control in the Image Optimisation chapter.
Always observe the acoustic output display for possible effects.
Best practices while scanning
TIPS: Only amplify the acoustic output power after attempting image enhancement with the controls that have no effect on
the acoustic output, such as gain and TGC.
WARNING
Be sure to read the descriptions of the individual controls for each operating mode you use, and make
sure that you have understood them before attempting to adjust the acoustic output power or other con-
trols that affect the acoustic output power.
Use the minimum necessary acoustic output power for achieving the best diagnostic photogrammetry during an
examination. Begin the exam with the probe that provides an optimum focal depth and penetration.
Acoustic output default levels
In order to assure that an examination does not start at a high output level, the system initiates scanning at a
reduced default output level. This reduced level is programmable by default and depends upon the examina-
tion icon and probe selected. It takes effect when the system is switched on or when the New Patient func-
tion is selected. To modify the acoustic output, adjust the power output level in the soft menu.
