Hz Scan Repetition Rate is the rate of the same identical point of
successive frames, sectors, or scans and applies to automatic
scanning systems (modes) only.
mm Output beam dimensions are the dimensions of the ultrasound
beam (-6dB pulse beamwidth) in a specified direction normal to
the beam alignment axis and at the transducer output face. In
scanning modes, these shall refer to the center scan line only.
MHz The Arithmetic-mean Acoustic Working Frequency is the
arithmetic mean of the frequencies f1 and f2 at which the
amplitude of the spectrum of the acoustic signal first becomes
3dB lower than the peak amplitude.
% Acoustic Power-up Fraction is the ratio of the peak rarefactional
acoustic pressure when the system is in Powerup mode to the
maximum value of the the peak rarefactional acoustic pressure
for any system settings of a specified mode of operation. This
ratio is determined from measurements made at the position
which yields the maximum pulse-pressure-squared integral (or
maximum mean square acoustic pressure for CW)
% Acoustic Power-up Fraction is the ratio of the peak rarefactional
acoustic pressure when the system is in Initialization mode to the
maximum value of the the peak rarefactional acoustic pressure
for any system settings of a specified mode of operation. This
ratio is determined from measurements made at the position
which yields the maximum pulse-pressure-squared integral (or
maximum mean square acoustic pressure for CW)
mW This is the Maximum Temporal Average power output. For
scanning modes, this shall be the total power output of all the
acoustic pulses.
