9.5 Sound power setting

Acoustical power adjustment
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 responsible for the default settings.
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 you turn on the scanner, change transducer, set a new patient, the system
settings will be the default ones.. 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. For a definition of terms used in the
acoustical output tables, see Appendix C
