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.
artifact. 1. any artificial product; a structure or appearance that is not natural, but is due to manipulation. 2. distortion or fuzziness of an image caused by manipulation, such as during compression of a digital file. film artifact artificial images on x-ray films due to storage, handling, or processing. phantom artifact artificial images seen with conventional tomography. standardization artifact an electrical stimulus of 1 mV deliberately introduced into the electrocardiogram so that pulse amplitudes on the tracing can be adjusted to 10 mm.
