Description

Detailed Description of the Invention (&) Technical Field of the Invention The present invention relates to an ultrasonic wave #IIrrMi [related to佽) Conventional technology and learning points Using an ultrasonic diagnostic device, a probe containing a transducer that oscillates ultrasonic waves is placed on the body surface! ! A predetermined section PmgI is formed by emitting ultrasonic waves into the body and obtaining reflections of the ultrasonic waves.

This type of ultrasonic diagnostic equipment is constructed as shown in Figure 1.
is a block diagram, (bl) is a side view of the probe, and (b) is a plan view. 0 The transmitting unit 2 outputs an oscillation signal to the probe 3 according to the command from the tying control unit 1. By the way
The pulse 3 oscillates ultrasonic waves.The pulse 3 receives the reflection of the oscillated ultrasonic wave, and the received signal is sent to the receiver 6.The received signal amplification timing controller 1 controls the receiver 5 and the video signal. The image generator 30 of the over-display section 7 generates a jI signal in the creation section 6 and outputs one image to the display section 7.
An output of 7 frames/second is required, and in order to obtain this output, K varies depending on the ultrasonic frequency and the diagnostic distance, so the configuration is such that the drive of the probe 3 is controlled by the transducer controller 4. As shown in (bl), in the probe 3, a vibrator 3D is rotatably provided inside a cover 3BC held on a case 3A by a shaft 3C, and signal lines are connected by a cable 3E. This vibrator 3D has axis 3C
The tube is formed in such a way that the arrow AO swings or expands at the center of the tube, and the oscillated ultrasonic waves are output radially to diagnose a predetermined range.

Therefore, for the object to be diagnosed 10, a tomographic image 1 of the X-X cross section is
0-1 is obtained. To diagnose the entire object 10 to be diagnosed, the case 3A is rotated in the direction of arrow B as shown in (bx)K, and the cross section Xs -Xs -Xa - is obtained.
Each Xa-Xs tomographic image is required.

Conventionally, the case 3A is rotated as described above by grasping the case 3A by hand and gradually rotating the case 3A in the direction of arrow B to obtain each tomographic image. In order to accurately diagnose the entire diagnostic object 10, K must perform such rotation around the center C--C. However, since the center shifts when rotated by hand, there is a problem in that it is not possible to accurately diagnose the entire patient.

For example, when diagnosing the heart, it is common practice to obtain long-axis and short-axis images of the heart as described above.

(C) Purpose of the Invention The purpose of the present wA is to eliminate the above-mentioned problem by preventing the rotation axis of each tomographic image from shifting when obtaining each tomographic image in the long axis or the short axis. It is.

(d) Structure of the Invention In the ultrasonic diagnostic apparatus of the present invention, the tomographic image is rotated around a predetermined axis so that a coaxial axillary section image can be obtained. The transducer is rotated around a predetermined wrinkle axis in accordance with the P cost, and the ultrasonic diagnostic apparatus is characterized in that it is equipped with a rotation means and a rotation control section that controls the rotation means. is achieved.

(e) Examples of the invention The present invention will be explained in detail below with reference to FIG.

FIG. 2 shows an embodiment of the ultrasonic diagnostic apparatus according to IJiK, in which (a) is a block diagram, (b) is a top view of the probe, and (b) is a sectional view.

(In the case of a>, as shown in the diagram, the rotation control unit 8 is connected to the probe 9, and the transducer 9D housed in the probe 9 is rotated around a predetermined axis by the rotation control unit 80 command. All other details are as shown in (a) in Figure 1.
) has the same configuration.

As shown in (b8), the fourth waveguide 9 is provided with a cover 9BK over the tip of a case 9A, and a vibrator 9D, and a signal line is connected by a cable 9F. This vibrator 9D is fixed by a shaft 9C rotatably held by a support fitting 9EK. A gear G1 is fixed to the shaft 9C, a gear G2 is connected to the gear 01, and a bearing Bl is connected to the gear G2.
It is coupled to a rotating shaft 9G supported via. On the other hand, the rotation shaft 9H supported via the bearing B2 has +
7G: 1115%tstL, *-? G3dllKD-D
As shown in (bt) in the figure, support A
It is formed so as to be integrated with a gear provided on the inner circumferential surface of 9H.

Therefore, if you want to obtain a tomographic image, (b) the axis of rotation 9G is arrow B.
By rotating the gear in the direction of G2. The shaft 9C is rotated through G'S, and the vibrator 9D is rotated or oscillated in the direction indicated by the arrow. Next, if you want to obtain a coaxial tomographic image centered on the center C-C, move the (support) axis 9H with the arrow F.
By rotating the support metal fitting 9 in the direction
E is rotated, and the vibrator 9D is rotated in the direction of arrow B, so that a coaxial tomographic image of the center C-C is obtained. Therefore, if you want to obtain a coaxial tomographic image, cover 9B of expansion plate 9
The distal end 9B-11 of the object to be diagnosed 100 is attached to the body and held, and the rotation control unit 8 is commanded to move the transducer 9D in the direction of arrow B.
Obtained by rotating in the direction. Also, the rotation angle at that time is C
It may also be fitted onto the RT. There is no need to rotate the case 9A by hand as in the conventional case, and since no axis deviation occurs when the case 9A is rotated, an accurate coaxial tomographic image can be obtained.

(f) More than the effects of the invention It is a good thing because it is configured so that it can rotate around C. This makes it possible to obtain coaxial tomographic images without having to hold the probe by hand, and to obtain accurate tomographic images with no deviation in the rotational axis, making it possible to perform accurate diagnosis.
