Method of improving quality of ultrasound image and ultrasound imaging apparatus therefor

Abstract

Provided is an ultrasound imaging apparatus and method of controlling the ultrasound imaging apparatus. The ultrasound imaging apparatus includes an ultrasound transceiver module, a display, an input interface, and at least one processor, wherein the at least one processor is configured to control the ultrasound transceiver module to transmit an ultrasound signal to a fetus and receive an ultrasound echo signal reflecting from the fetus, obtain ultrasound volume data of a face of the fetus based on the ultrasound echo signal, the ultrasound volume data including a lossy volume area where the ultrasound echo signal has a value equal to or less than a threshold value due to a strong reflector, display a two dimensional (2D) rendered image of the face of the fetus based on the ultrasound volume data and an ultrasound cross-sectional image of the face of the fetus through the display, the 2D rendered image including a lossy area not represented of the face of the fetus due to the lossy volume area, indicate an area to be restored among the lossy area on the 2D rendered image or the cross-sectional image of the ultrasound volume data, and restore the indicated area to be restored based on a user input to restore the 2D rendered image or the ultrasound cross-sectional image of the ultrasound volume data being received through the input interface. The ultrasound imaging apparatus may display a location of a landmark of a face on a 2D rendered image of the face of a fetus, and clearly enhance the shape of the landmark at the location of the landmark.
