An ultrasonic includes: a piezoelectric layer; an absorbing layer disposed at a lower portion of the piezoelectric layer, configured to absorb an acoustic signal; and a connection part disposed between the piezoelectric layer and the absorbing layer. The connection part may deform at least partially so that a plurality of acoustic signals radiated from the piezoelectric layer due to the connection part have different magnitudes. In the case of the ultrasonic probe, since the magnitude of the acoustic energy radiated from the center of the ultrasonic probe is larger than the magnitude of the acoustic energy radiated from the side of the ultrasonic probe, the directivity of the ultrasonic signal is improved and a side lobe is decreased. In addition, an apodization effect capable of suppressing overlapping between adjacent phases can be obtained by using a difference in the magnitude of the acoustic energy to be radiated.

Ultrasonic probe

Disclosed is an ultrasonic probe in which a supporting member is provided with a buffer unit to mitigate an outside impact. The ultrasonic probe includes a transducer rotatably provided, a shaft having the transducer mounted thereto, and a supporting member rotatably supporting the shaft, wherein the supporting member is provided with a buffer unit to mitigate an outside impact.

An ultrasound probe having a rotatable transducer array for providing an improved field of view (FOV) and an improved scan angle includes a transducer comprising a transducer array and rotating at a predetermined angle. A supporting member supports the transducer and includes a rotation guide which is in contact with the transducer while the transducer rotates.

Disclosed herein is an ultrasonic probe. The ultrasonic probe includes a matching layer having flexibility, a piezoelectric layer disposed on the bottom surface of the matching layer and having flexibility, a first backing layer disposed on the bottom surface of the piezoelectric layer and having flexibility, a second backing layer disposed on the bottom surface of the first backing layer and including a plurality of backing material layers stacked perpendicularly to the first backing layer, and second backing layer adjusting units respectively disposed between every two of the plurality of the stacked backing material layers of the second backing layer and changing the shape of the backing material layers.

Disclosed herein are an ultrasound probe and a method of controlling the same. Image quality reduction in a 3D image may be prevented, and blurring of an ultrasound image may be removed via image correction by independently installing position detecting sensors on a transducer module and a motor of the ultrasound probe, detecting a backlash increasing as time, and compensating a variation of the backlash. The ultrasound probe includes a first sensor to detect a position of a transducer changed by rotation, a second sensor to detect rotation of a driving device, and a controlling to determine a backlash between signals of the first and second sensors and correcting an ultrasound image.
