o1:
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 For non–scanning modes and/or non–scanning components
o1x1:
of combinational modes: time average acoustic power at the source,

per cm , in milliwatts. This is the acoustic power emitted from the
2
central 1 cm of the active non–scanned aperture through which the
highest acoustic power is being transmitted.
