摘要： An ultrasound probe including: a circuit substrate (23) having a recess in a first region on the lower surface side; a buffer layer (400) composed of an insulating material on a second region different from the first region of circuit substrate (23); and an element array layer (22) including a first piezoelectric element (100) for ultrasound transmission formed in the first region of the circuit substrate (23) without the buffer layer (400), and a second piezoelectric element (200) for ultrasound reception formed in the second region of the circuit substrate (23) on the buffer layer (400). The first piezoelectric element (100) vibrates in a flexural vibration mode on the circuit substrate (23), and the second piezoelectric element (200) vibrates in a thickness vibration mode on the circuit substrate (23).

摘要： An ultrasound transducer that achieves broadband characteristics without degrading the sensitivity of the ultrasound transducer. Piezoelectric element (202) includes piezoelectric thin film (203), first electrode (204) that is disposed on a first surface of piezoelectric thin film (203) in a thickness direction of piezoelectric thin film (203), and second electrode (205) that is disposed on a second surface of piezoelectric thin film (203) in the thickness direction of piezoelectric thin film (203), and at least two of parameters of a spring constant, a viscosity coefficient, and a mass in an equivalent single damped oscillation model representing a structure of a diaphragm composed of each piezoelectric cell (200) are each set to a value that is different among the piezoelectric cells (200) such that a relationship between a driving frequency ratio and a phase in the diaphragm is substantially identical among the piezoelectric cells (200).

摘要： Described is an ultrasound diagnostic imaging apparatus which includes an ultrasound probe and which generates ultrasound image data sets for displaying an ultrasound image. The ultrasound diagnostic imaging apparatus includes a transmitting unit which performs ultrasound scanning for a plurality of times so that a part of or all of scan regions overlap in a plurality of different directions, an image processing unit which generates a plurality of ultrasound image data sets according to the receive signals and an anisotropic aspect evaluation unit which evaluates an anisotropic aspect of ultrasound wave reflection in the subject according to at least either of the ultrasound image data sets and the receive signals. In the ultrasound diagnostic imaging apparatus, the image processing unit generates synthetic image data in which the plurality of ultrasound image data sets are synthesized according to an evaluation result of the anisotropic aspect evaluation unit.

摘要： An ultrasound probe and ultrasound diagnostic apparatus that achieve high transmission/reception sensitivity and wide frequency band are provided. The ultrasound probe includes a pMUT array in which a plurality of pMUTs are arranged. The pMUTs include first pMUTs for ultrasound transmission and pMUTs for ultrasound wave reception having a structure different from that of the first pMUTs. The cell region of each first pMUT and the cell region of each second pMUT are separated from each other in the ultrasound wave radiation plane.
