Abstract: Imaging and Doppler ultrasounds creatively employing recent radar and sonar technologies are rapidly growing with numerous new exciting developments. Velocity sensing techniques can be as simple as C.W. Doppler up to the multi-channel MTL High density, multi-elements linear array, phase array and annular array transducers benefit from the synthetic aperture and open a new era of a real time scanning of the biological structures with unprecedented quality. Flow velocity color mapping, power Doppler, tissue Doppler, contrast agents echo enhancement and other new, exciting developments will be discussed
