Plot of mean and standard deviation of error in attenuation slope in (a) percent and in (b) decibels per megahertz versus the number of echoes used to determine E[|Vscat(f)|2]compensated for the 0.5 dB/cm·MHz tissue-mimicking phantom with the focus of the transducer positioned 2.23 cm into the phantom using the SS algorithm. The rectangular window length used to gate the time-domain signals was 6.16 mm.
