PA.3

@MI

max

the derated pulse average intensity at the point of maximum reported MI

(Watts per square centimeter).

The Acoustic Measurement Precision and Acoustic Measurement Uncertainty are

summarized below.

Quantity Precision Total Uncertainty

Pll.3 (derated pulse intensity integral) 3.2 % +21 % to –24 %

Wo (acoustic power) 6.2 % +/– 19 %

Pr.3 (derated rarefaction pressure) 5.4 % +/– 15 %

Fc (center frequency) < 1 % +/– 4.5 %

Explanatory Notes

(a) This index is not required to this operating mode.

(b) This probe is not intended for adult transcranial uses.

(d) The maximum index value is less than 1.0

* If the MI comes from a scanning mode Transmit Pattern (pulse), the ‘prr’ listed is

the average per second for the 'worst case' scan line. ‘prr’ for scanning modes is the

product of the frame rate and the number of pulse per line of the Transmit Pattern .

** The max TIS unscanned value is an ‘at_surface’ value and occurs for aperture > 1.0

, OR The max TIS unscanned value is a ‘below_surface’ value and occurs for

aperture <= 1.0 cm

+ The max TIB for this combinational mode = the at_surface TIS_scanned value. The

non–scanned_TIB value indicated is the below_surface max. A “+” is used when the

TIB value is less than the TIS_scanned value for the operating condition.
