Abstract:
An ultrasonograph comprising:a sensor having an ultrasound sending unit for sending ultrasound to a region to be diagnosed and an ultrasound receiving unit for receiving ultrasound waves reflected from the diagnosed region; a band for holding the sensor from a back side thereof relative to the diagnosed region and positioning a front side of the sensor against the diagnosed region; an information acquisition unit for acquiring information about the diagnosed region based on the reflected waves received by the ultrasound receiving unit; and an ultrasound-attenuating portion interposed between the sensor and the band for attenuating propagation of external noise from the band to the sensor and attenuating propagation of ultrasound signals through the band, the ultrasound-attenuating portion comprising a recess formed in the band opposite the sensor and recessed relative to the sensor to define an empty space between the sensor and the recessed portion.
