FDA Acoustic Output Data

The following tables list the typical maimum acoustic output
levels achievalbe with LOGIQ 7 for all probes and operational
modes. It is intended that this is information be useful in making
ALARA decisions and selecting the most appropriate probe for
the application. In accordance with US FDA Guidelines, the
overall maximum acoustic SPTA intensity for LOGIQ 7 is limited
2
to 720 mW/cm and MI is limited to 1.9. Modes for which TI does
not exceed 0.1 are indicated by <0.1.
Table 1-1 shows all of the probes' operating modes. The
following pages contain probe acoustic output tables for those
noted in Table 1-1.
