Abstract
Ultrasonic imaging method includes sequentially emitting by each transducer group of respective regions, into which transducers are divided, focused ultrasonic pulses to a focal point of an object; sequentially acquiring, by each transducer group, ultrasonic echo signals from the focal point based on the emitted ultrasonic pulses; calculating a normal vector of a surface of the object using emission directions of the focused ultrasonic pulses and intensities of the ultrasonic echo signals in correspondence to the focused ultrasonic pulses emitted by three of the transducer groups; calculating an attenuation rate of the ultrasonic echo signals using the normal vector and the emission directions of the focused ultrasonic pulses emitted by the three of the transducer groups, and correcting the ultrasonic echo signals based on the attenuation rate; beamforming the ultrasonic echo signals, an attenuation of which has been corrected, into ultrasonic image signals to be output as an ultrasonic image.
