Abstract:
1. An ultrasound probe which transmits an ultrasonic beam toward a subject and receives an ultrasonic echo by the subject, the ultrasound probe comprising: a transducer array for a B-mode image which has a plurality of ultrasound transducers and which transmits and receives an ultrasonic beam for a B-mode image; and a transducer array for sound speed measurement which is laminated and formed above the transducer array for a B-mode image and has a smaller number of ultrasound transducers than the plurality of ultrasound transducers of the transducer array for a B-mode image and which transmits and receives an ultrasonic beam for sound speed measurement, wherein an array pitch of the ultrasound transducers in the transducer array for sound speed measurement is equal to an array pitch of the ultrasound transducers in the transducer array for a B-mode image, and the transducer array for sound speed measurement is located above the central portion of the transducer array for a B-mode image.
