Problems solved by technology

[0013] In addition, in Patent Document 2, it is assumed that the scanning speed of the ultrasonic probe is maintained at a constant speed by the spring, so a moving mechanism for moving at a constant speed is required, which hinders miniaturization.

[0093] figure 1 An example of the adapter for ultrasonic diagnosis of this embodiment is shown. This ultrasonic diagnostic adapter 1 is disposed between an ultrasonic probe of an ultrasonic diagnostic apparatus and a body surface (subject) of a target site. The adapter 1 for ultrasonic diagnosis includes a packing 14 and a reflective member disposed inside the packing 14, and the reflecting member includes a material having an acoustic impedance different from that of the packing material. The pad is made of a material (for example, polymer gel) that can be easily adhered to the curved surface of the subject. In contrast, the reflective member is made of a material such as aluminum or stainless steel. Here, the material of the reflective member is preferably a material that has high hardness and is not easily corroded even if it is placed in the spacer for a long time. In addition, the material of the gasket preferably has a sound velocity of 1450 (m / s) to 1585 (m / s) and a...

[0123] The present embodiment is characterized in that an image of the reflective member can be detected from a B-mode image including images of the cushion and the subject using the pad in which the reflective member is arranged, and the position of the ultrasonic probe can be calculated.

[0124] In the following description, a 3D image display mechanism that forms a 3D image from a plurality of B-mode images will be described as an example.

[0125] First, for an overview of the operation of the 3D image display mechanism of this embodiment, refer to Figure 8 The state transition diagram to illustrate. The initial state is the freeze mode (802). In this state, the ultrasonic probe does not transmit ultrasonic waves. Then, after the operator releases the frozen state ( 811 : Freeze OFF), the mode changes to the B-mode image recording mode ( 801 ), whereby a B-mode image can be recorded. In this state, the operator acquires a plurality of B-mode images by moving the ultra...

[0168] In this embodiment, other forms of the pad and other forms of the ultrasonic diagnostic apparatus will be described.

[0169] First, refer to Figure 17 The problems addressed in this embodiment will be described.

[0170] Figure 17 (a) is a cross-sectional view showing the gasket 14 when the ultrasonic probe 13 is in close contact with the main surface 15 of the gasket 14 , Figure 17 (b) is a cross-sectional view of the gasket when there is a gap 1701 between the ultrasonic probe 13 and the main surface 15 of the gasket 14 , that is, the ultrasonic probe is not in close contact with the main surface 15 of the gasket.

[0171] In the first and second embodiments, the mode in which the position of the ultrasonic probe is calculated from the vertical distance from the main surface of the spacer to the reflection member has been described. However, the ultrasonic probe may float from the main surface of the gasket due to shaking of the hands or the like. In this case...

Abstract

An ultrasound diagnostic adapter used when diagnosing a subject using an ultrasound probe that transmits and receives ultrasound waves, the ultrasound diagnostic adapter includes: a pad which has (i) a main surface that is a surface on a side where the ultrasound probe is disposed, and (ii) a back surface that is a surface which is opposite to the main surface and is on a side where the subject is disposed; and a first reflective member which is disposed inside the pad and made from a material having a different acoustic impedance than a material included in the pad, wherein the first reflective member is disposed such that at least one of (i) a distance between the first reflective member and the main surface and (ii) a width of the first reflective member viewed from the side of the main surface varies depending on a position in the main surface.

Description

technical field [0001] The present invention relates to an adapter for ultrasonic diagnosis, an ultrasonic diagnostic apparatus, and an ultrasonic diagnostic method used when diagnosing a subject with an ultrasonic probe. Background technique [0002] An ultrasonic diagnostic device is a diagnostic device that acquires and displays in vivo information as an ultrasonic image by utilizing the reflection of ultrasonic waves in a living body, and is used as a useful device that can non-invasively observe a state in a living body. [0003] A schematic diagram of an ultrasonic diagnostic device is shown in Figure 34 shown. In the ultrasonic diagnostic apparatus, an ultrasonic probe 13 is used to transmit and receive ultrasonic waves. An ultrasonic vibrator for transmitting and receiving ultrasonic waves is provided inside the ultrasonic probe. An ultrasonic probe injects ultrasonic pulses generated and transmitted by an ultrasonic vibrator into a subject, and receives reflected...
