Abstract
A signal processing device according to an embodiment includes adjustment circuitry and processing circuitry. The adjustment circuitry adjusts a received signal based on an echo of an ultrasonic wave transmitted to a subject with gain corresponding to a location at which the echo has been generated. The processing circuitry corrects the received signal that has been adjusted by the adjustment circuitry and calculates an index value relating to attenuation by using the corrected received signal.
