CAUTION:
Note that for switches other than those marked *, the MI/TI
value may change in a direction not intended for the above
parameters.
24.1.4 Operating procedures for MI/TI
The control of ultrasound output and the most useful switches for this purpose are
described below.
(1)
[ACOUSTIC POWER]
knob
The output intensity is one of the available
ultrasound output control parameters. It can
be adjusted with the
[ACOUSTIC POWER]
knob at the right end of the main panel. To
decrease ultrasound output, turn the knob
counterclockwise and to increase ultrasound
output, turn the knob clockwise.
(2) Setting the defaults for
[ACOUSTIC POWER]
Selection of diagnostic applications is the most important factor for controlling
ultrasound output.
The permissible level of intensity of ultrasound differs depending on the region of
interest. For fetal examinations, in particular, much care must be exercised. For
this reason, the
switch must be used to reset the parameters for each new
patient, and the
[Preset]
menu must be used to select the settings appropriate for
each new region of interest.
In this system, imaging presets can be created using the ultrasound output set by
the user. At this time, the default function is disabled.
Any changes to the default setting value are the responsibility of the user.
Default choices
Initial power
0% to 100%*
* Definition of 100%:
The maximum acoustic power of a transducer determined by the
increase in transducer surface temperature in the selected mode and
the acoustic power restrictions specified by the FDA.
* Any value less than 1% is displayed as 0.XX%.
