Abstract
Provided is an electromechanical transducer which is capable of correcting or compensating a fluctuation in the transmission/reception characteristics of an elastic wave transmitting/receiving unit due to applied pressure. The electromechanical transducer (102) which transmits/receives elastic waves such as ultrasound includes the elastic wave transmitting/receiving unit (201) for transmitting/receiving elastic waves, a pressure detecting unit (203) for detecting pressure that is applied to the elastic wave transmitting/receiving unit, and a correcting unit (204). Based on pressure information which is detected by the pressure detecting unit, the correcting unit performs at least one of a correction of elastic wave transmitted/received signals relevant to the elastic wave transmitting/receiving unit and a correction of the transmission/reception characteristics of the elastic wave transmitting/receiving unit.
