Problems solved by technology

Therefore, compared with the case where the central positions of the transmitting aperture and the receiving aperture are aligned in the slice direction, the sound intensity at the hot spot becomes smaller and the resolution decreases, so the accuracy of ultrasonic measurement decreases.
[0006] In addition, there is a technical problem that, as described above, if the ultrasonic wave is transmitted in a direction inclined at a predetermined angle with respect to the slice direction of the ultrasonic wave, an internal tomography of the object is generated based on the reception result of the ultrasonic wave received by the receiving array. In the case of an image, it is necessary to perform signal processing and image processing of the received signal in consideration of this angle change, and the processing becomes complicated

no. 1 approach

[0053] Hereinafter, an ultrasonic measuring instrument as an electronic device according to a first embodiment of the present invention will be described based on the drawings.

[0054] Composition of Ultrasonic Measuring Instrument

[0055] figure 1 It is a perspective view showing a schematic configuration of the ultrasonic measuring instrument 1 according to the present embodiment. figure 2 It is a block diagram showing a schematic configuration of the ultrasonic measuring instrument 1 .

[0056] like figure 1 As shown, the ultrasonic measuring instrument 1 of the present embodiment includes an ultrasonic probe 2 and a control device 10 electrically connected to the ultrasonic probe 2 via a cable 3 .

[0057] In this ultrasonic measuring instrument 1 , an ultrasonic probe 2 is brought into contact with the surface of a living body (for example, a human body), and ultrasonic waves are emitted from the ultrasonic probe 2 into the living body. In addition, among ultrasoni...

no. 2 approach

[0127] Next, a second embodiment according to the present invention will be described.

[0128] In the first embodiment described above, the receiving elements 52 are arranged adjacently. On the other hand, the second embodiment is different in that, in the ultrasonic element group, the transmitting element 51 is arranged in the X direction and the Y direction of the receiving element 52 .

[0129] In addition, in the following description, the same code|symbol is attached|subjected to the same structure as 1st Embodiment, and the description is abbreviate|omitted or simplified.

[0130] Figure 10 It is a top view schematically showing an ultrasonic element group 5B of the second embodiment.

[0131] like Figure 10 As shown, a plurality of receiving elements 52 are arranged in the rectangular second area Ar2, and a plurality of transmitting elements 51 and receiving elements 52 are arranged. The position of the center of gravity of the receiving area where the receiving ...

no. 3 approach

[0136] Next, a third embodiment according to the present invention will be described.

[0137] In the second embodiment, the transmitting elements 51 and the receiving elements 52 are alternately arranged in the X direction and the Y direction in the second region Ar2. In contrast, the third embodiment is different in that the receiving elements 52 are arranged along the diagonal of the receiving area.

[0138] Figure 11 It is a top view schematically showing the ultrasonic element group 5C of the third embodiment.

[0139] like Figure 11 As shown, the plurality of receiving elements 52 are arranged along the diagonal line L1 of the second region Ar2 so as to be shifted one by one on the +X side and the +Y side. In addition, one receiving element 52 is arranged at a position overlapping with the central position P0. The center of gravity of the receiving area where the receiving element 52 is arranged coincides with the center position P0 of the transmission / reception ar...

Abstract

An ultrasonic device includes a plurality of ultrasonic element groups each including at least one transmitting element adapted to transmit an ultrasonic wave and at least one receiving element adapted to receive an ultrasonic wave, and arranged along an X direction, and in each of the ultrasonic element groups, a centroid position of the receiving area, in which the receiving element included in the ultrasonic element group is disposed, overlaps a transmitting area, in which the transmitting element included in the ultrasonic element group is disposed, in a projection view along a Y direction.

Description

technical field [0001] The invention relates to an ultrasonic device, an ultrasonic module and an ultrasonic measuring instrument. Background technique [0002] Conventionally, there is known an ultrasonic diagnostic apparatus (ultrasonic measurement apparatus) that transmits and receives ultrasonic waves using an ultrasonic probe to form an ultrasonic image (for example, refer to Patent Document 1). [0003] In the device described in Patent Document 1, the ultrasonic probe has a transmission array and a reception array. Among them, the transmitting array is constituted by a one-dimensional array in which a plurality of fundamental wave transducers corresponding to the fundamental wave are arranged in one direction (scanning direction) according to an arrangement condition corresponding to the fundamental wave. In addition, the receiving array is constituted by a one-dimensional array in which a plurality of harmonic oscillators corresponding to ultrasonic waves correspond...
