Acoustic Output Tables
IEC 60601-2-37 Tables
Symbols and Denitions
Standard 60601-2-37 published by the International Electrotechnical Commission (IEC)
requires the declaration of acoustic output information. The denitions and units of the
symbols in those tables are listed below, and are consistent with IEC 60601-2-37 and IEC
62359. Denitions for CAPITALIZED parameters, if not found here, can be found in the
reference documents.
All table entries have been obtained at the operating conditions that give rise to the
Maximum Index Value (shown in the second row of the table). Due to the complexities
of the system user interface, it may be dicult to exactly replicate the declared condition.
Contact Samsung Medison for further information as needed.
Note that Samsung Medison provides information for both of the TIS non-scanned
columns. The ‘Aaprt≤1’ (cm
2
) column is an ‘at_sur face’ TIS value and the ‘Aaprt>1’ (cm2)
column is a ‘below surface’ TIS value. The tables will provide additional informational ags
(‘**’) in the event that the largest TIS non-scanned value is an ‘at_surface’ value with Aaprt >
1 cm2, or if the largest TIS non-scanned value is a ‘below_sur face’ value with Aaprt ≤ 1 cm2
case (very rare).

P the time -average ultrasonic OUTPUT POWER radiated by the transducer
for the transmit pattern(s) associated with the report-ed Index. For
TIS_non_scan and TIB_non_scan this is the total acoustic power of
the non-scanned beam(s). For TIC it is the total acoustic power of the
contributing modes (which will be list-ed separately, for the reader to
sum). The reported maximum TIS_scan value may (likely) come from a
combinational mode. In this case, P = P1 + P1x1. P1 is the BOUNDED
OUTPUT POWER (the maximum power emitted from a one cm width
of the active (scanned) transmit aperture of the transducer in the scan
plane direction) of each the scanned transmit modes. For instance in
2D color mode P1_2D and P1_Col will be listed. P1x1 is the ma-ximum
contribution from any one square centimeter of the non-scanned
transmit mode(s) active aperture. (milliwatts).

Explanatory Notes
(a) This index is not required in this operating mode.
(b) This probe is not intended for adult transcranial or neonatal cephalic applications.
(c) This formulation for TIS is less than that for an alternate formulation in this mode.
(d) The maximum index value is less than 1.0 in all modes.
* 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 non-scanned value is an ‘at_sur face‘ value and occurs for aperture > 1.0
cm
2
, OR The max TIS non-scanned value is a ‘below_surface‘ value and occurs for
aperture <= 1.0 cm2.
+ 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 this TIB value
is less than the TIS_scanned value for the operating condition.

FDA Tables
Symbols and Denitions
All table entries have been obtained at the same operating conditions that give rise to
the maximum Index Value in the second row. Due to the complexities of the system user
interface, it may be dicult to exactly replicate the declared condition. Contact Samsung
Medison for further information.
Symbols used in the table are described below.
MI the Mechanical Index.
TIS
scan
the Soft Tissue Thermal Index in an auto scanning mode.
TIS
non–scan
the Soft Tissue Thermal Index in a non auto scanning mode.
TIB the Bone Thermal Index.
TIC the Cranial Thermal Index.
A
aprt
the area of the active aperture (square centimeters).
p
r.3
the derated peak rarefactional pressure associated with the transmit pattern
giving rise to the value reported under MI (meg zapascals).
W
o
For TIB and TIC: time average acoustic power at the source, in milliwatts. (Also
see the denitions for W01 and W
01x1
that follow.)
For TIS scan, W
o =
W
o1 +
W
o1x1
For TIS non–scan, W
o
=
W
o1x1
W
o1:
For scanning modes and/or scanning components of combinational modes:
time average acoustic power at the source, per cm, in milliwatts. This is the
acoustic power emitted from the central 1–cm length, in the scan direction, of
the aperture corresponding to the scanned pulses.
W
o1x1:
For non–scanning modes and/or non–scanning components of combinational
modes: time average acoustic power at the source, per cm2, in milliwatts.
This is the acoustic power emitted from the central 1 cm2 of the active
non–scanned aperture through which the highest acoustic power is being
transmitted.
W
.3(z1
) the derated ultrasonic power at axial distance z1 (milliwatts).
I
TA.3(z1
) the derated spatial peak, temporal average intensity at axial distance z1
(milliwatts per square centimeter).
z
1
the axial distance corresponding to the location of max[min( W.3(z), I
TA.3
(z) x 1
cm2)], where z = zbp (centimeters).
z
bp
(centimeters).
z
sp
For MI, the axial distance at which p
r.3
is measured for TIB, the axial distance at
which TIB is a maximum (i.e., zsp = z
B.3
) (centimeters).
d
eq
(z) the equivalent beam diameter as a function of axial distance z, and is equal to
[(4/3.14)(Wo/ITA(z))]
0.5
where ITA(z) is the temporal average intensity as a function
of z (centimeters).
f
c
is the center frequency (MHz). For MI, fc is the center frequency associated
with the transmit pattern giving rise to the maximum reported value of MI.
For TI, for combined modes involving transmit patterns of unequal center
frequency, fc is dened as the overall range of center frequencies of the
respective transmit patterns.
Dim. of A
aprt
the active aperture dimensions for the azimuthal and elevational planes
(centimeters).
PD the pulse duration (microseconds) associated with the transmit pattern giving
rise to the reported value of MI.
PRF the pulse repetition frequency associated with the transmit pattern giving rise
to the reported value of MI (Hz).
p
r
@PII
max
the peak rarefactional pressure at the point where the free-eld, spatial peak
pulse intensity integral is a maximum (megapascals). See Section 6.2.4.1 of the
Output Display Standard, entitled "Measurement Methodology for Mechanical
and Thermal Indices".
d
eq
@PII
max
the equivalent beam diameter at the point where the free-eld, spatial peak
pulse intensity integral is a maximum (centimeters). See Section 6.2.5.1 of the
Output Display Standard, entitled "Measurement Methodology for Mechanical
and Thermal Indices".
Page 63
Reference Manual 59
FL the focal length, or azimuthal and elevational lengths, if dierent (centimeters).
I
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
PII.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.
(c) This formulation for TIS is less than that for an alternate formulation in this mode.
(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 cm2,
OR The max TIS unscanned value is a ‘below_surface’ value and occurs for aperture <=
1.0 cm2.
+ 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.
