Provided is an ultrasound imaging system configured to generate data of an ultrasound image based on an echo signal received by each of a plurality of elements included in an ultrasound transducer that transmits and receives ultrasound. The ultrasound imaging system includes: a determining circuit configured to determine, using a signal corresponding to the echo signal received by each of the plurality of elements, whether each of the plurality of elements has a sensitivity decrease； a region specifying circuit configured to specify a region where sensitivity decreases in the ultrasound image, based on a contribution degree indicating a ratio of transmission intensity contributing to an ultrasound beam by an element that has been determined as having the sensitivity decrease by the determining circuit； and a sensitivity display circuit configured to generate data for displaying the region specified by the region specifying circuit.
