TI or MI ≥ 1.0
Transducer Model

Even if MI is less than 1.0, the system provides a continuous real-time display of MI in all imaging modes, in increments
of 0.1.
The system meets the output display standard for TI and provides a continuous real-time display of TI in all imaging
modes, in increments of 0.1.
The TI consists of three user-selectable indices, and only one of these is displayed at any one time. In order to display
TI properly and meet the ALARA principle, the user selects an appropriate TI based on the specific exam being
performed. FUJIFILM SonoSite provides a copy of
determining which TI is appropriate.

MI and TI output display accuracy

The accuracy result for the MI is stated statistically. With 95% confidence, 95% of the measured MI values will
be within +18.0% to -20.3% of the displayed MI value, or +0.2 of the displayed value, whichever value is larger.
The accuracy result for the TI is stated statistically. With 95% confidence, 95% of the measured TI values will be
within +21.0% to -27.8% of the displayed TI value, or +0.2 of the displayed value, whichever value is larger.
A displayed value of 0.0 for MI or TI means the calculated estimate for the index is less than 0.05.
