"Webtion in ultrasound system is digital beamforming. Digital beamforming, as applied to the medical ultrasound, is defined as phase alignment and summation [3] of signals that are gen-erated from a common source, by received at different times by a multi-elements ultrasound transducer [4]. The commonly use arrays are linear, curved, or phase array. " - Ultrasound dynamic beamforming
