The probe operating unit is provided with a linear operating means for displacing the ultrasound transducer linearly for a linear scan, and a radial operating unit for rotating the ultrasound transducer for a radial scan, in combination with a mode selector means for switching the operation of the ultrasound transducer between linear scan mode in which the transducer is displaced linearly during transmission and reception of ultrasound signals and a radial scan mode in which the transducer is rotated during transmission and reception of ultrasound signals. | |
