Transmit-focusing and beam-forming method and apparatus

摘要

The present invention relates to an adaptive transmit-focusing and a beam-forming method and apparatus. The present invention 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. The present invention 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 present invention reduces transmit-focusing and beam-forming errors generated from applying a single pattern of delay profile, and provides clear ultrasonic images. <IMAGE>
