Abstract:
An ultrasound probe includes: an ultrasound transducer including plural piezoelectric elements; an acoustic lens layer configured to radiate the ultrasound emitted from the plural piezoelectric elements to outside; a back layer that faces the acoustic lens layer with the ultrasound transducer interposed between the back layer and the acoustic lens layer; and a wiring member having at least a part that is arranged at a first position between the acoustic lens layer and the ultrasound transducer or at a second position that faces the ultrasound transducer with the back layer interposed between the second position and the ultrasound transducer. The wiring member includes: a resin layer having electrically insulating; and an electrically conducting layer that is provided on the resin layer and includes plural signal wirings.
Abstract:
An ultrasound transducer includes: a plurality of piezoelectric devices, each of the plurality of piezoelectric devices being configured to emit an ultrasonic wave according to an electrical signal input thereto, and convert an incident ultrasonic wave from an outside into an electrical signal; and an outer surface in which a material of a scanning surface transmitting and receiving an ultrasonic wave is constituted of a self-repairing material.
Abstract:
An ultrasound transducer array according to an embodiment includes a substrate, a plurality of groove-like recesses arranged at a predetermined interval on one surface of the substrate, a cell region arranged between the recesses on the one surface side of the substrate, a flexible film configured to cover the substrate and the cell region and having fragility lower than fragility of the substrate, and a dividing groove having a width smaller than a width of the recess and reaching from the other surface of the substrate to the flexible film in the recess.
Abstract:
A method for manufacturing an ultrasound transducer includes a first step of manufacturing a wiring layer by arranging insulating fibers on conductive threads, a second step of electrically connecting one end of the plurality of conductive threads to a transducer array unit, a third step of providing a first backing material after providing a second backing material so that at least connection sites between the transducer array unit and the conductive threads are embedded, and a fourth step of curing the first backing material so as to fix the transducer array unit and the wiring layer.

Abstract:
An ultrasound endoscope, having a cable for connecting the ultrasound endoscope to a driving apparatus, includes an insertion section insertable into a subject, a plurality of transducers provided at a distal end portion, an electrode formed in each of the transducers, a wiring section connected to the electrode to electrically connect the electrode and the cable, and matching circuits, at least one of which is provided at an end of or partway in each of the wiring section. The electrode, the wiring section, and the matching circuits are provided in each of the plurality of transducers. The cable includes a core wire and an insulating layer enwrapping the core wire and functions as a matching section that matches electric impedance of each of the transducers between the plurality of transducers and the driving apparatus by varying a thickness or quality of material of the insulating layer.
