Embodiment 1

[0092] A plurality of tetrapod-shaped zinc oxide fibers (TPZ) are added as binding fibers to liquid epoxy resin (trade name manufactured by Emerson & Cuming, ェコビンド 27) [abbreviated as EPR]. The total amount was 3% by volume, and then a curing agent was added, put into a polyethylene container, stirred for 5 minutes with a rotary mixer, and uniformly mixed to prepare an acoustic backboard composition. The TPZ used here has a shape in which four zinc oxide fibers are bonded at one end and the other ends extend in different directions. Each zinc oxide fiber has a diameter of about 2 μm and a length of 40 to 50 μm. In addition, the shape in which four zinc oxide fibers of substantially the same length protrude in different directions and the one in which four zinc oxide fibers with a length in the range of 40 to 50 μm protrude in different directions exist in a mixture of multiple TPZs. shape.

[0093] Next, the acoustic backboard composition was subjected to a degassing treatmen...

Embodiment 2～7

[0095] Materials for acoustic backing layers were produced in the same manner as in Example 1, except that EPR, TZP, and the second filler were mixed in the ratios shown in Table 1 below.

Embodiment 8

[0097] Add a plurality of tetrapod zinc oxide fibers (TPZ) identical to Example 1 in liquid nitrile rubber (Japan Zeon company produces trade name, liquid NBR) [abbreviated as NBR], its relative to this NBR and TPZ The total amount is 5% by volume, and Fe with an average particle size of 5 to 10 μm is added at 5% by volume relative to the total amount of NBR and particles. 2 o 3 After the particles were placed in a polyethylene container, they were stirred for 5 minutes with a rotary mixer, and uniformly mixed to prepare an acoustic backboard composition. Next, this acoustic backboard composition was degassed for 10 minutes in a vacuum container, and placed in a container containing Teflon (registered trademark). Next, curing was performed at 80° C. for 24 hours to manufacture a material for an acoustic backing layer.

Abstract

The present invention provides a mini ultrasonic probe which comprises an acoustic backing layer with high strength, high insulating property, high interchannel homogeneity, excellent exothermic character and big damping decrement. The acoustic backing layer is characterized in that: the ultrasonic probe has an acoustic backing layer made of a composite resin material including a resin and a plurality of bonded fibers contained the resin, and the composite resin material exhibits an acoustic impedance of 1.3 to 6 MRayls at 25 DEG C. The bonded fibers is formed of a plurality of zinc oxide fibers bonded to each other at one edge portions and extending in different directions in the other edge portion; a plurality of channels are arranged on the acoustic backing layer with space, and each channel has a piezoelectric element and an acoustic matching layer formed on the piezoelectric element; and an acoustic lens formed to cover at least the surface of the acoustic matching layer of each channel.

Description

technical field [0001] The present invention relates to an ultrasonic probe for transporting and receiving ultrasonic signals to a subject or the like, and an ultrasonic diagnostic apparatus including the ultrasonic probe. Background technique [0002] In a medical ultrasonic diagnostic device or an ultrasonic image inspection device that transmits an ultrasonic signal to an object and receives a reflected signal (reflected wave signal) from the object to image the inside of the object, a device with an ultrasonic signal is mainly used. An array ultrasonic probe with transceiver function. This array type ultrasonic probe is known as a one-dimensional array type ultrasonic probe obtained by arranging 50 to 300 channels having piezoelectric elements and acoustic matching layers formed on the piezoelectric elements in a one-dimensional direction, and A two-dimensional array ultrasonic probe obtained by arranging 500 to 10,000 of the above-mentioned channels in a two-dimensiona...
