Abstract: An ultrasound imaging system includes an ultrasound imaging device configured to transmit and receive a signal based on transmission and reception of an ultrasound wave. The ultrasound imaging device includes a processor including hardware. The processor is configured to: generate a plurality of pieces of data of ultrasound images of an inside of a subject based on the signal, the ultrasound images being spatially separated from one another; invert a magnitude relationship of a luminance value of each of pixels in each of the ultrasound images; automatically set a first boundary across which the luminance value changes by a predetermined amount based on data of one of the ultrasound images; and automatically detect a second boundary in each of the ultrasound images based on the set first boundary.
