  • Publication number: 20250017567
    Abstract: The disclosure provides an ultrasound imaging device including a linear array, a first phased array, a second phased array, and a signal processing unit, wherein the linear array transmits and receives an image ultrasound signal to acquire an ultrasound image inside a human body; the first phased array provides a first Doppler ultrasound transmission signal to a vascular region included in the ultrasound image; and the second phased array provides a second Doppler ultrasound transmission signal to the vascular region; and an ultrasound imaging device including a dual-mode probe identifying a vascular region where blood vessels are located based on an ultrasound image acquired using a linear array at every predetermined time interval, focusing a Doppler ultrasound transmission signal on the vascular region using one or more phased arrays disposed on both sides of the linear array, and calculating a blood flow velocity by a received Doppler ultrasound reception signal.
