1. An analysis apparatus, comprising:
processing circuitry configured to:
generate a harmonic signal based on a reception signal that is collected by an ultrasound probe, and generate a fundamental wave signal based on the reception signal, the ultrasound probe transmitting ultrasound to a subject, receiving a reflected wave of the ultrasound generated in the subject, and generating the reception signal based on the reflected wave, the harmonic signal corresponding to a harmonic component of the reflected wave, the fundamental wave signal corresponding to a fundamental wave component of the reflected wave,
calculate a first index value indicating tissue properties of the subject based on the harmonic signal, and calculate a second index value indicating the tissue properties based on the fundamental wave signal;
generate an analysis result based on the first index value and the second index value;
display the analysis result;
wherein
the processing circuitry is further configured to:
generate a first tissue property image corresponding to a first region in a region of interest based on the first index value;
generate a second tissue property image corresponding to a second region in the region of interest based on the second index value, the second region being different from the first region;
generate a third tissue property image corresponding to the region of interest as the analysis result by synthesizing the first tissue property image and the second tissue property image
calculate a first displacement caused in the subject by using phase information of the harmonic signal;
calculate the first index value based on the first displacement;
calculate a second displacement caused in the subject by using phase information of the fundamental wave signal; and
calculate the second index value based on the second displacement.
