1. An ultrasonic diagnostic apparatus comprising:
a memory storing a program; and
one or more processors which, by executing the program, function as:
an ultrasonic image generation unit configured to generate a first brightness mode image of a subject;
an inference unit configured to infer a region of interest on the first brightness mode image generated by the brightness mode image generation unit by using a trained model trained with a region of interest to cover on a blood flow region and a surrounding region of the blood flow region on a second brightness mode image by using teaching data including the blood flow region of the second brightness mode image and the region of interest set on the second brightness mode image, wherein the trained model is used for identifying a blood flow region from the first brightness mode image and setting the region of interest on the first brightness mode image;
a blood flow image generation unit configured to generate a blood flow image in the region of interest inferred by the inference unit; and
a display unit configured to display at least one of the blood flow image and the first brightness mode image generated by the ultrasonic image generation unit.
