摘要： An adaptive transmit-focusing and beam-forming method and apparatus is provided, which in connection with beam-forming applies adaptive patterns of delay profiles to reflected ultrasonic pulses from a group of ultrasonic pulses, received by transducer arrays, forms multiple sets of preliminary scan-line data, and combines the multiple sets of preliminary scan-line data into single scan-line data; and in connection with transmit-focusing performs focusing a group of ultrasonic pulses by applying a plurality of delay profiles in accordance with propagation velocities within an object region to be ultrasonic imaged. The adaptive transmit-focusing and beam-forming method and apparatus reduces transmit-focusing and beam-forming errors generated from applying a single pattern of delay profile, and provides clear ultrasonic images.
