Image reversal marks 4, 4a are ones obtained by making a design of the side surface shape of the probe 100 and the mark 4 shows 'non-reversal' while the mark 4a shows 'reversal'.

Description

[Detailed Description of the Invention] [Industrial Application Field 1] The present invention relates to an ultrasonic diagnostic apparatus, and in particular, a mark display function that displays a mark near a tomographic image on a screen that displays a tomographic image of a photographed living body. The present invention relates to an ultrasonic diagnostic apparatus having:

[Prior Art] In an ultrasonic diagnostic device, a tomographic image of a photographed living body is displayed on a display screen to indicate which part of the living body the tomographic image belongs to, that is, which part the ultrasound probe should be applied to. In order to clearly indicate what has been obtained, an indicating means called a body mark is usually used. For example, in the ultrasonic diagnostic apparatus described in Japanese Patent Publication No. 81-34338, a tomographic image 21 is displayed on the display screen (CRT screen) of taken tomographic images and the screen of recorded photographs, as shown in FIG. 8A of the present application. , body mark 22, probe mark 23, date, patient identification number 24, etc. are displayed simultaneously.

Therefore, if you look at this photo at a later date, you will be able to roughly tell which part of the body the tomographic image is from, which can be useful for diagnosis and re-examination.

[Problems to be Solved by the Invention] However, with conventional body marks and probe marks, it is possible to know the approximate position of the body where the probe is applied, but the mark indicates the direction in which the probe is applied. It cannot be known more intuitively.

For example, by changing the orientation of the probe, the scanning direction of the ultrasound beam on that cross section changes, and as a result, the vertical or horizontal direction of the tomographic plane changes, causing confusion in diagnosis or reexamination. Sometimes.

In order to compensate for this drawback, in Utility Model Application No. 55-101108, the probe mark is represented by an arrow 25 to indicate the scanning direction, as shown in FIG. 6B of the present application. In addition, in Utility Model Opening Show 133-18108, the 6th
Identification mark 2 indicating the observation direction of the tomographic image 21 as shown in Figure C
B is displayed together with the probe mark 23.

However, these two methods both
It displays the scanning direction or observation direction of 1.
It does not intuitively inform the observer of the direction in which the probe is actually applied.

The present invention provides a probe mark that eliminates the drawbacks of the prior art, and by looking at the mark, it is possible to intuitively understand which part of the body the probe is applied to and in what direction. An object of the present invention is to provide an ultrasonic diagnostic apparatus that can accurately reproduce imaging conditions during diagnosis and reexamination.

[Means and Effects for Solving the Problems J According to the present invention, an ultrasonic pulse is transmitted from an ultrasonic probe and made incident on a subject, and an echo signal reflected within the subject is received. An ultrasound diagnostic device that displays an ultrasound image includes a body mark display means that displays a body mark near the ultrasound image on the display screen, and an ultrasound probe that is placed on the subject at a predetermined position on the body mark. A probe mark display means for displaying a probe mark indicating the contact position and angle of the probe, and an image reversal mark display means for displaying an image reversal display mark indicating whether or not there is an operation for reversing the image. The touch mark and the image reversal display mark have shapes that allow the direction of the probe to be identified, and the relative relationship between the subject and the image can be intuitively identified from the image reversal display mark and the probe mark. .

According to one feature of the invention, the probe mark includes a substantially rectangular first portion corresponding to the width and length of the ultrasound probe and a cable connection of the probe in the first portion. and a second portion representing.

According to another feature of the invention, the image reversal display mark includes a substantially rectangular first portion corresponding to the height and length of the ultrasound probe; and a second portion representing a cable connection.

[Example] Next, an example of the ultrasonic diagnostic apparatus according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 shows an embodiment of the ultrasonic diagnostic apparatus according to the present invention.
The basic device configuration for its ultrasonic diagnostic function may be the same as that of a conventional ultrasonic diagnostic device, so a detailed explanation thereof will be omitted. Above the mark, a probe mark indicating the direction of the ultrasound probe and a reverse display mark indicating whether or not an operation to reverse the image is performed are displayed. The operator can intuitively know the left/right, J: bottom, relative relationship between the subject and the image from these two marks.

In the body probe mark generating section 180 shown in FIG. 1, graphic data representing the above-described body mark, probe mark, and image inversion display mark is stored in advance in a storage device such as a ROM. Regarding probe marks, in addition to storing marks at different angles in advance in ROM, there are two methods:
In order to save the capacity of M, a method of drawing marks to be displayed each time may be applied. A part of the ultrasonic wave is reflected inside the measured part and is received by the probe 10G as an ultrasonic echo signal.

The received echo signal passes through the receiving circuit 12, is converted into a digital signal by the receiving processing circuit 140, and is input to the DSG circuit 150. The DSC circuit 150 stores this signal and the display mark of the mark generation section 180 selected by the operation section 180 in the memory, and displays the tomographic image and the display mark on the CRT surface l of the display section 180 (FIG. 2). . The operation of each part of these devices is controlled by a control circuit 130. The photographing section +70 includes an imaging device such as a camera that photographs the image displayed on the 1 display section 160.

Referring to FIGS. 2 and 3, the body mark 5 displayed on the CRT surface l specifies body part marks such as the chest region and abdominal region, which are arranged on the operation panel 300 shown in FIG. body mark switch 200.

When the probe 100 and its cable connection portion 18 are viewed from the direction of the arrow 14, they have the shapes of the upper surfaces 13 and 13a in both figures. The probe marks 3 and 3a shown in FIG.
This is a stylized version of these top shapes, with the short side being the probe +
00 thickness, a generally rectangular portion whose long sides correspond to the lengths or widths thereof, and a circle mark 20 or 20a representing the cable connection portion 18 of the probe 100. The direction of the probe 100 is indicated by the circles 20 and 20a. By displaying this over the body mark 5, it is possible to specifically represent the position and angle at which the probe 100 hits the body 11. mark 3
Since the directions of tomograms 2 and 3a differ by 180 degrees, it is possible to show the reversal of tomographic images 2 and 2a. Specifically, the probe key 230 of the operation panel 300 in FIG.
This is a mark with an extremely large amount of information.

Operation panel 300 (7) REV *-240 is CR
It is operated when it is desired to invert the TR2O3 image. Image reversal marks 4 and 4a are shown in FIGS. 2 and 4.

It is a stylized version of the side shape of the probe 100, and as shown in FIG. 2, the short side corresponds to the height of the probe 100, and the long side corresponds to its length. and a rectangular part representing the cable connection part 19 of the probe 100.

The mark 4 indicates "no reversal" and the mark 4a indicates "with reversal." In this way, the top surface shape and side surface of the directional probe 100 are reflected in the probe mark indicating reversal and the image reversal mark. By using a stylized shape, the relationship between the image and the subject can be intuitively identified.

The operator places the probe 100 on the body 11 as shown in FIG.
When the cross section 12 is photographed by applying it to the display section 113 in FIG.
The obtained tomographic image 2 is displayed on the CRT screen of 0. Next, the body mark 5 of the photographed part is displayed on the operation unit
When selecting one of the body marks 200 on the operation panel 300, the corresponding body mark 5 stored in the body probe mark generation section 180 is displayed on the CRTR 7 of the display section 160. When the body mark key 230 on the operation panel 300 is pressed in order to display the position and direction or angle on the body mark 5, the CRTR 2
The probe mark 3 is displayed superimposed on the O3 body mark 5. So 1. PO5ITIO of the operation panel 300 so that the position and angle of this probe mark 3 match the position and angle of the actual probe 100 applied to the body 11.
Operate the N key 210 and the ANGLE key 220.

FIG. 3 is a photograph of the same cross section 12 of the same body 11 as in FIG. 2, but the orientation of the probe 100 is 180'.
Since they are different, a tomographic image 2a that is left and right reversed with respect to the tomographic image 2 in FIG. 2 is displayed on the CRTR 7 in FIG. The body mark 5 is displayed in the same way as in FIG. 2, but the probe mark 3a is set and displayed in a direction 1800 different from mark 3 in FIG.

After photographing, the display on the CRT screen l by the photographing section 170 is as follows.
For example, it is recorded on a visible image recording medium such as instant film. If you look at the probe mark 3.3a and the body mark 5 in FIG. 2 or 3 in the recorded image, you can immediately tell where on the body 11 the probe lO was applied and at what angle. I can understand it. Especially 5. The circle mark 20 or 20a on the probe mark 3 or 3a represents the position of the cable connection part 19 of the probe 100, so if you look at the displayed probe mark, you can see that it is actually the position of the probe 100. You can intuitively know the direction.

Furthermore, in the prior art, the scanning direction is displayed on the body mark, but the scanning direction can be changed independently of the direction in which the probe is applied. For example, the operation panel 300 in FIG.
By pressing the image inversion key 240, the left and right display directions are inverted in the DSC circuit 150 of FIG.
As shown in FIG. 3, the image 2a obtained by applying the probe 100 to the body 11 may be inverted and displayed as image 2 in FIG. In the example, in order to clearly indicate the relative relationship between the orientation of the probe 100 and the image, image inversion display marks 4 and 4a shown in FIGS. 3 and 4 are provided.

More specifically, if we look at both the probe mark 3 and the image inversion display mark 4 in FIG. It can be clearly understood which direction of the body 11 corresponds to. In the case of FIG. 2, the right abdomen of body H corresponds to the left side of image 2. In the case of Fig. 3, the image reverse display mark 4 is
Since the orientation is the same as that in FIG. 2, when the probe 100 is laterally inverted and applied to the body 11, the image 2a is laterally inverted from that in FIG. In the case of FIG. 3, it can be seen that the left abdomen of the subject corresponds to the left side of image 2. At this time, in order to make the examinee's right abdomen (actually the examinee's left abdomen) correspond to the right side of the image as seen from the vehicle inspector, the image reversal display key 240 can be operated. You can change the display direction as shown in the figure.

In this example, by using the probe mark and the image inversion display mark together, it is possible to clearly and immediately know the position of the probe and the corresponding positional relationship between the subject's body and the image. This provides very useful information for diagnosis.

In the conventional example, the arrow probe mark 25 shown in FIG. 8B,
It may be possible to estimate the positional relationship between the subject and the image 21 based on the information obtained from the identification mark 2B indicating the observation direction and the body mark 22 shown in FIG. 6C, but,
There are four possible combinations of the forward and reverse directions of the probe and whether or not the image inversion key is operated.Therefore, when examining a large number of subjects, there is a risk of inefficiency and erroneous judgments. was there. In addition, the arrow probe mark 25 indicates the scanning direction, but does not indicate the actual direction of the probe.0As is well known, the position of the probe in ultrasound diagnosis is extremely delicate. Therefore, the probe mark display of this embodiment, which allows the user to quickly grasp the contact position and angle of the probe on the body, is effective for medical examinations.

[Effects of the Invention] As described in detail above, according to the present invention, by looking at the probe mark and the image inversion display mark displayed on the body mark, the captured ultrasound tomographic image can be adjusted by the ultrasound probe. You can intuitively know where on the body and in what direction the tentacle is applied to obtain the desired result. This also allows the specific location of the probe to be known, providing a wealth of information useful for diagnosis and reexamination.
