“…Among these beamformers, APES provided the lowest value inside the cyst region together with the MV with temporal averaging, indicating a low amount of energy leakage into this area. Speckle statistics are quantified using the pixel signal-tonoise ratio (SNR p ) (1.91 for fully developed speckle), defined as the mean value divided by the standard deviation within a speckle region [13]. Table I summarizes these values for each of the beamformers.…”

“…A constant check of the correct functioning of the probes and calibration of ultrasound signal emitted are mandatory to ensure the reliability of the technique (157,185). Each device has a specific calibration procedure and requires its own calibration phantom (generally composed of plastic material or Plexiglas) for QC (157).…”
