1. An information processing device comprising:
a control unit configured to:
acquire a plurality of frame images generated by using line data indicating intensity of a reflection wave with respect to an ultrasound radially transmitted from an ultrasound transducer moving inside a biological tissue;
extract a first region from the plurality of frame images based on a ratio between an average of luminance in a first region of interest included in the plurality of frame images and a dispersion of luminance in the first region of interest;
extract a second region from the plurality of frame images based on at least one feature amount in a second region of interest included in the plurality of frame images; and
determine a region commonly included in the first region and the second region as a specific region.
