Abstract: The invention is directed to a handheld portable ultrasound device comprising a transducer further comprising piezoelectric elements that emit ultrasonic waves and capture echoes from tissues inside of a patient; a processing unit Field Programmable Gate Array comprising a General Control Device module, a Pulse Emission Control module, a Wave Conformation module, and an Image Processing module; Pulse Generation and Front-End Unit having a pulse generator, a plurality of switches transmission/reception, and a Front-End circuit generating digitized signals; an Imaging and Transmission Unit; and a Visualization Device. The General Control Device module coordinates operations of the Pulse Emission Control modules of Beamforming and Image Processing; the Pulse Emission Control module drives the Pulse Generator; the Beamforming module receives digitized signals or samples stream from the Front-End Circuit delivers a coherent summation of digitized signals by applying selective delays to digitized signals.
