ULTRASONIC IMAGING APPARATUS AND CONTROL METHOD FOR THEREOF

摘要

Provided are an ultrasonic imaging apparatus which is capable of accurately and quickly estimating a point spread function necessary for restoring an ultrasonic image, and a control method thereof. An ultrasonic imaging apparatus according to an embodiment includes a probe configured to irradiate ultrasonic waves toward a target area of an object, to receive an ultrasonic echo which is reflected from the target area, to convert the received ultrasonic echo into an electrical signal, and to output as an ultrasonic signal; a receiving beam forming part for beam forming the ultrasonic signal and to output the beam forming ultrasonic signal; a point spread function database configured to store a point spread function which is acquired based on a situational variable, and a phase parameter which is determined based on the situational variable, for the beam forming ultrasonic signal; and an image generator configured to select the acquired point spread function and the determined phase parameter from the PSF database based on the beam forming ultrasonic signal, and to perform a deconvolution using an estimated point spread function based on the selected PSF and the selected phase parameter in order to generate an image.
