Ultrasound imaging device including dual mode probe

An ultrasound imaging device comprising:

• a linear array transmitting and receiving an image ultrasound signal to acquire an ultrasound image inside a human body;
• one or more phased arrays providing a Doppler ultrasound transmission signal to a vascular region included in the ultrasound image;
• and
• a region divider dividing the vascular region into a plurality of division regions;
• wherein,
• the one or more phased array comprises a first phased array providing a first Doppler ultrasound transmission signal to the vascular region included in the ultrasound image and a second phased array providing a second Doppler ultrasound transmission signal to the vascular region;
• and
• the ultrasound imaging device focuses the first Doppler ultrasound transmission signal and the second Doppler ultrasound transmission signal on a selection region disposed farthest, among the division regions of the vascular region, from the positions on which the first Doppler ultrasound transmission signal and the second Doppler ultrasound transmission signal are focused.
