Ultrasound imaging system, operating method of ultrasound imaging system, and computer-readable recording medium

An operating method of an ultrasound imaging system configured to generate data of an ultrasound image based on an echo signal received from each of a plurality of elements included in an ultrasound transducer that transmit and receive ultrasound, the operating method comprising:

• determining, using a signal corresponding to the echo signal obtained by receiving from each of the plurality of elements, concerning the elements, whether a decrease in reception sensitivity occurs;
• and
• causing, based on a position of an element where the determining determines that the decrease in the reception sensitivity occurs, a display to display at least one of display data indicating an image region where sensitivity decreases in the ultrasound image and information for informing that a sensitivity decreased element in which a decrease in reception sensitivity occurs is present, wherein
• the determining includes
• acquiring sensitivity information of the plurality of elements,
• extracting an element having the sensitivity information smaller than a first threshold as a candidate element serving as a candidate of the sensitivity decreased element, and
• determining, using a statistical value of sensitivity information of a predetermined number of elements located in a near field region of the candidate element, whether a decrease in reception sensitivity occurs in the candidate element.

A non-transitory computer-readable recording medium with an executable program stored thereon, the program causing an ultrasound imaging system configured to generate data of an ultrasound image based on an echo signal received from each of a plurality of elements included in an ultrasound transducer that transmit and receive ultrasound, to execute:

• determining, using a signal corresponding to the echo signal obtained by receiving from each of the plurality of elements, concerning the elements, whether a decrease in reception sensitivity occurs;
• and
• causing, based on a position of an element where the determining determines that the decrease in the reception sensitivity occurs, a display to display at least one of display data indicating an image region where sensitivity decreases in the ultrasound image and information for informing that a sensitivity decreased element in which a decrease in reception sensitivity occurs is present, wherein
• the determining includes
• acquiring sensitivity information of the plurality of elements,
• extracting an element having the sensitivity information smaller than a first threshold as a candidate element serving as a candidate of the sensitivity decreased element, and
• determining, using a statistical value of sensitivity information of a predetermined number of elements located in a near field region of the candidate element, whether a decrease in reception sensitivity occurs in the candidate element.
