Researchers went through 17 studies that examined the penis size of more than 15,000 men. They found that the average flaccid penis lengthâfrom the base to the opening on the tipâwas 3.6 inches and the circumference, measured around the base or mid-shaft, was 3.7 inches.
Reverberation artifact is a common ultrasound artifact and occurs when a sound pulse reverberates back and forth between two strong parallel reflectors.With the exception of comet-tail artifact, a subtype of reverberation, reverberation artefact has little diagnostic use.: Reverberation artifact occurs when an ultrasound pulse gets trapped between two strong parallel reflectors.
reverberation. an artifact in ultrasound imaging resulting from the production of spurious echoes which are caused by reflections at the skin-transducer interface or by bone or gas.See also comet-tail.entioned in? 1  amphoric resonance. 2  anechoic chamber. 3  artifact. 4  axial resolution. 5  circuit. 6  comet sign. 7  comet tail artifact. 8  comet tail sign. 9  comet-tail. 10  dirty shadowing. 11  echo. 12  mirror-image artifact. 13  neural oscillation. 14  NMR. 15  nuclear magnetic resonance. 16  palpatory percussion. 17  resonance. 18  ring-down artifact. 19  skodaic resonance.
