1. An ultrasound imaging system comprising:
a processor comprising hardware, the processor being configured to:
generate data of an ultrasound image of a subject;
set a first boundary in the ultrasound image across which luminance values of pixels in the ultrasound image changes by a predetermined amount, the first boundary representing a boundary between a first portion of the subject and an external portion external of the first boundary;
set, based on the first boundary set, a second boundary from within the first boundary in the ultrasound image, the second boundary representing a boundary between the first portion of the subject external of the second boundary and a second portion of the subject internal of the second boundary;
delete a region between the first boundary and the second boundary; and
after deleting the region between the first boundary and the second boundary, invert a magnitude relationship of a luminance value of each pixel in the ultrasound image.
