9.5 Sound power setting
Acoustic output regulation
According to the bottom of the screen menu area [soft sound power] project regulating sound
power. Regulation at the same time, the soft menu item and the middle of the screen will display
the sound power offset position size. Numerical sound power level is big, said the sound output of
current energy increases.
In the frozen state of the image, the ultrasonic energy is not output.
Default settings description
The operator is the most important factor to control the sound output
The intensity level depends on the acoustic output in the scanning area. In the fetal examination,
be especially careful control of acoustic output intensity.
In this system, the user can preset the image parameters. Once the preset change default settings
for the original machine becomes invalid. Therefore, the user is responsibleforthedefault
settings.
Default setting range
Initial setting range of
sound output
10% to 100%
The maximum acoustic output limit depending on the selected mode of the probe surface
temperature rise and the provisions of the FDA acoustic output of each probe.
Be
careful
：
When the boot, probe switch, new patient or return to the preset value, the system will
automatically return to the user preset value. In a factory setting, sound power value is
lower than the preset value. The user in accordance with the principle of ALARA and
meet the FDA 510 (k) Guidance-Track3 limits, the user can through the corresponding
increase in the sound power soft menu you can also set the AP value in the preset level.
The sound output system is based on EN60601-2-37:2008, FDA510 (K) GUIDANCE, the
diagnostic ultrasound equipment acoustic output measurement standard (NEMA UD-2 2004) ","
diagnostic ultrasound equipment thermal and mechanical index real-time display standard (AIUM
and NEMA UD-3 2004) were measured and calculated. The acoustic output of published values
see Appendix C.
