Abstract
An image generation apparatus includes an arithmetic processing unit that generates an ultrasonic image based on a received signal obtained by receiving a reflected wave from a subject of an ultrasonic wave incident on the subject. The arithmetic processing unit calculates an attenuation feature value at each position in an incidence direction of the ultrasonic wave based on the received signal, performs signal processing on the attenuation feature value at each position in the incidence direction, and generates an attenuation feature image using the attenuation feature value subjected to the signal processing.
