[0002]

2. Description of the Related Art An ultrasonic diagnostic imaging apparatus obtains, in real time, an ultrasonic image representing the pulsation of the heart, the movement of a fetus, etc. by a simple operation of applying an ultrasonic probe to the body surface of a subject. be able to. In addition, since the physical quantity to be handled is sound waves, high safety, repeatability of examinations is possible, and the system scale is smaller than other diagnostic devices such as X-ray, CT, MRI, etc. It has various features such as easy inspection. Recently, a small ultrasonic diagnostic imaging apparatus that can be carried with one hand has been developed.

[0003] On the other hand, in the past, a doctor or a nurse had to perform a procedure, but nowadays, medical instruments by which a subject can operate a device to automatically perform measurement and the like are increasing. A typical example is a sphygmomanometer. Many sphygmomanometers currently installed in clinics or the like display instructions necessary for measuring blood pressure by themselves or have a voice guidance function. The subject can perform the measurement himself without relying on a doctor or a nurse by using these functions.

As described above, ultrasonic diagnosis is a medical device that can be used relatively safely without being affected by exposure, such as X-rays. With the development of speech recognition technology or human interface technology in recent years, there is a possibility that the patient himself will be able to acquire a diagnostic image without the assistance of a doctor or an ultrasonic technician in the future even with this ultrasonic diagnostic imaging device .

[0005]

However, the following problems are encountered in realizing the above-described ultrasonic image diagnostic apparatus that enables a patient to obtain a diagnostic image by himself / herself.

[0006] First, in ultrasonic diagnosis, scanning is performed while scanning the cross section of an organ to be diagnosed, and an ultrasonic image is taken to obtain an appropriate diagnostic image. However, this procedure requires some training.

Second, training is required to view the obtained ultrasonic diagnostic images. For example, the position of the right atrium, left ventricle, and the like can often not be understood by a person other than a specialist even by looking at a heart cross-sectional image. Therefore, it is difficult to determine whether or not the ultrasonic image displayed on the monitor is appropriate (desired) when capturing the ultrasonic image.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a first embodiment and a second embodiment of the present invention will be described with reference to the drawings.

(First Embodiment) FIG. 1 is a diagram showing a schematic configuration of an ultrasonic diagnostic imaging apparatus 10 according to a first embodiment.

In FIG. 1, an ultrasonic diagnostic imaging apparatus 10
Are an ultrasonic probe 12, a transmitting unit 14, a receiving unit 16, a DSC (digital scan converter) 1
8, an image synthesizing unit 20, a display unit 22, a guidance processor 24, a speaker 26, an operation panel 28, an image memory 30, an ECG 32, a storage medium 34, a thermometer 36, and an interface circuit 38. The solid frame 11 in FIG. 1 indicates the main body of the ultrasonic diagnostic imaging apparatus.

The ultrasonic probe 12 is a probe for irradiating a subject (patient) with ultrasonic waves for imaging and receiving a reflected wave from the subject, and includes a piezoelectric element or the like. Is formed.

The transmission unit 14 has a trigger generator, a delay circuit, and a pulser circuit (not shown). The transmission unit 14 generates a pulsed ultrasonic wave and sends it to the vibrating element of the probe to generate a focused ultrasonic pulse.
Ultrasonic waves irradiated into the subject via the ultrasonic probe 12 are received by the probe 12 again as echo signals scattered by the tissue of the subject.

The receiving unit 16 has a preamplifier, an A / D converter, a receiving delay circuit, and an adder (not shown). The echo signal output to the receiving unit 16 for each element of the probe 12 is amplified for each channel by a preamplifier, and A / D converted by an A / D converter. The echo signal after the A / D conversion is given a delay time necessary for determining the reception directivity by the reception delay circuit, and is added by the adder. The echo signal after this addition has a reflection component from a direction corresponding to the reception directivity emphasized. An overall ultrasonic beam for transmission and reception is formed by the transmission directivity and the reception directivity. Further, the echo signal after the addition is subjected to logarithmic amplification, envelope detection processing, and the like, and the intensity of the echo signal becomes data expressed by brightness.

The DSC 18 receives the output signal from the receiving unit 3 and obtains from the scanning line signal sequence of the ultrasonic scan,
It is converted into a scanning line signal sequence of a general video format represented by a television or the like.

The image synthesizing unit 20 synthesizes character information, scales, and guidance images (to be described later) of various setting parameters into one frame, and outputs it to the display unit 22 as a video signal. Thus, a tomographic image representing the shape of the subject tissue is displayed.

The display section 22 is a monitor composed of a CRT or the like.

The guidance processor 24 outputs various guidance instructions for diagnosis based on various software programs and the like used for guidance stored in the storage medium 34 to the image synthesizing unit 20 as an image or audio information to a speaker. Send to 26. Further, the guidance processor 24 may transmit the transmission unit 1 according to various situations.
4. Change the signal processing parameters of the receiving unit 16 and the DSC 18. Further, the guidance processor 24
It receives information from the operation panel 28 or acquires image information from the image memory 10.

The speaker 26 outputs a guidance voice, a warning sound, and the like, which will be described later, under the control of the guidance processor 24 so that the subject can appropriately acquire an ultrasonic image.

The operation panel 28 includes buttons, a keyboard,
It is an input means composed of a trackball, a mouse, etc., for inputting instruction information from an operator to the apparatus main body.

The image memory 30 comprises a storage memory for storing the signal of the DSC 18. This information can be called by the operator after the diagnosis, for example, and a moving image can be reproduced using a plurality of images.

The ECG 32 is an electrocardiogram measuring device for measuring an action potential generated on the body surface by an action current accompanying the excitation of the myocardium as an electrocardiogram waveform. The ECG 32 is connected to the ultrasound diagnostic imaging apparatus 10 and connected to the guidance processor 24.
Is controlled according to the guidance function. This ECG
The electrocardiogram measured by 32 is transmitted as diagnostic information to a doctor or the like via a network.

The thermometer 36 is connected to the ultrasonic diagnostic imaging apparatus 10 and is controlled by the guidance processor 24 according to the guidance function. The body temperature of the subject measured by the thermometer 36 is also transmitted as diagnostic information to a doctor or the like via the network.

The storage medium 34 stores various software programs used for guidance, and a library of sounds and images. It is also used for storing images in the image memory 30 and the like.

Next, with reference to FIG. 2, FIGS. 3 and 4 will be described with reference to FIG. 2 regarding the operation of acquiring an ultrasonic image according to the guidance function of the ultrasonic image diagnostic apparatus 10 configured as described above. It will be described with reference to FIG.

FIG. 2 is a flowchart of the diagnostic image collecting operation. In each step of the flowchart, the guidance function realized by the guidance processor 24 is classified into two types, a "guidance function related to image acquisition" and a "guidance function related to support". The “guidance function regarding image acquisition” is a function for guiding a work procedure and an operation method before image acquisition. "Guidance function for support"
Is a function for providing guidance for supporting the operator's work performed in accordance with the “guidance regarding image acquisition”. The guidance processor 24 stores a guidance program corresponding to each step in a storage medium 34.
And implements the guidance function described below.

In FIG. 2, first, the power supply of the system is turned on.
(Step S1), and preparation for diagnosis is performed (Step S2). The preparation for diagnosis includes maintenance when an abnormality occurs in the system, determination of a diagnosis protocol to be executed, and various measurements when an electrocardiogram or body temperature needs to be measured as preparation.

The diagnosis protocol is determined by the diagnosis site, the imaging mode, the subject ID, and the operator (in this case, the subject).
This is executed by inputting or selecting each item such as an ID. The determination of the diagnosis protocol is performed by selecting from pre-registered options according to voice or guidance displayed on the screen. Since the operator only needs to select an appropriate one from the options of each item, the operator can easily and quickly determine a diagnostic protocol.

The maintenance of the occurrence of system abnormality is as follows.
For example, when an abnormality occurs in the diagnostic system when the power of the system is turned on, the guidance processor 24 displays an error message on the display unit 22, issues a warning message from a speaker, or the like. At present, many circuit boards of a system are provided with a function of notifying information on an abnormal location when an abnormality occurs. The guidance processor 24 may be configured to acquire and display such information. Conversely, a configuration that does not display details related to the abnormality may be used, but it is preferable to issue an instruction such as "Please call a clerk" at least because the apparatus is a medical device. With such a configuration, the operator can
The abnormality can be easily recognized visually or by hearing. In addition, it is possible to promptly respond to the abnormality that has occurred.

When it is necessary to measure an electrocardiogram or a body temperature as a preparation, an instruction to mount the electrocardiogram or the body temperature is issued, and the mounting method is displayed as an animation with a sound.

FIG. 3 shows an animation guidance screen displayed on the display unit 22 by the guidance processor 24 when the electrocardiogram measurement is necessary, and shows the positions where the electrodes are attached. The subject can easily perform an electrocardiogram measurement or the like regardless of experience with the voice guidance from the speaker 26 and the guidance screen. In particular, presentation of the electrode attachment position by an image such as an animation is easy to understand and effective.

Next, scanning is started according to the guidance function (step S3).

That is, the guidance processor 24
Executes an instruction to the operator to obtain an image necessary for diagnosis, for example, according to the following procedure.

First, for an operator who has no experience in operating the ultrasonic diagnostic imaging apparatus, guidance on general operation methods such as how to hold the probe and how to apply the probe to the body surface is provided. FIG. 4 shows an example of a guidance screen displayed on the display unit 22 regarding how to hold the probe and how to apply the probe to the body surface. It is preferable that the voice guidance from the speaker 26 is also performed along with the guidance screen display. Operators who have no operation experience
With this guidance, it is possible to easily grasp the operation of the probe.

On the other hand, an experienced operator can skip the guidance on the general operation method by pressing the skip button. Note that the skip function can be executed for all the guidance performed by the present ultrasonic diagnostic imaging apparatus.

Next, guidance is provided for a technique for obtaining a desired tomographic image. For example, when the purpose is to acquire a four-chamber cross-sectional image of the heart, specific contact positions and angles of the probe will be described. At this time, as shown in FIG. 5, the display unit 22 displays the exemplary ultrasonic image 501 and the captured ultrasonic image 5.
02 is displayed. The operator can adjust the position of the tomographic image while following the two images while comparing the two images. As the model ultrasonic image 501, an appropriate image is selected according to a diagnosis protocol. The exemplary ultrasonic image 501 may be a representative diagnostic image stored in advance, or may be an image generated by computer graphics or the like so as to be more easily understood. Further, a description may be given of the exemplary ultrasonic image, for example, a structure in which a cursor is placed on a predetermined location in the image to explain what is displayed at the location.

By the way, a good image may not be obtained simply by changing the procedure as instructed by the guidance. The cause is that the image is dark (or too bright) because the display gain or dynamic range of the device is not appropriate,
Alternatively, it is conceivable that the transmission frequency is too high and the signal of the deep image drops. In these cases, the operator can adjust the gain or the transmission frequency according to the following guidance.

For example, assume that the image is dark. The image information in the image memory 30 is sent to the guidance processor 24 as needed. Guidance processor 24
Monitors the transmitted image, determines that the image is dark when the sum of the luminance values in the image is lower than a certain threshold level, and issues an instruction such as "increase the gain". Similarly, the guidance processor 24 monitors the transmitted image, and if there is a difference between the brightness at the shallow portion and the deep portion within the image that is equal to or greater than a certain threshold value, the transmission unit 14 or the
6 is instructed to change the transmission frequency.

In the above-described adjustment of the gain or the transmission frequency, as shown in FIG. 6, it is checked interactively with the operator to check if the image quality is appropriate. A configuration for instructing a change in setting may be used. At this time, the flowchart of FIG. 6 may be displayed on the display unit 22 as it is, or an image for explaining each step (for example, when increasing the gain, a knob of the gain is displayed by animation or the like, and further, at the same time as the explanation) (For example, a gain knob is lit). In these cases, since the operator is scanning the probe, it is not desirable to request a complicated operation (such as inputting a character) for the interaction. Therefore, it is desirable that the configuration be such that only a Yes / No button operation or a voice recognition function is used. It is difficult for an inexperienced operator to control ultrasound transmission / reception conditions and display conditions. However, according to such a configuration, each condition can be easily controlled. In addition, the blinking function of the knob, the voice recognition function, and the like are effective in reducing the burden on the operator during the control.

Next, when a desired cross section has been scanned, an image capture instruction for acquiring the ultrasonic image is issued (step S4).

In general, “breath holding” is necessary for obtaining a good ultrasonic image. Guidance processor 2
4 gives guidance on this breath-hold instruction. The breath holding instruction is selected from either the “inspiratory state” or the “expiratory state” based on the diagnostic site selected or input when the diagnostic protocol is determined. The guidance processor 24
In accordance with the selected breath-hold instruction, present an appropriate breath-hold instruction, such as "Breath big ... hold your breath there." The ultrasonic image is automatically acquired at the timing of the breath-hold instruction. The acquired image is
The data is transferred from the image memory 10 to the storage medium 34. In step S4, a capturing operation such as a freeze may be described, and the subject may be configured to manually capture an ultrasonic image. With this breath-hold guidance, even an inexperienced operator can acquire images at an appropriate breath-hold timing. Further, the automatic image capturing function linked to the guidance breath hold timing greatly reduces the burden on the operator.

The acquired image is checked by the guidance processor 24. As a method used for this check, an image recognition method that is already widely used, such as a contour extraction method, is used. For example, whether or not four cavities are visualized is determined as a criterion, or by correlating with the exemplary ultrasonic image, it is determined whether or not “similar”, and if the value is equal to or less than the criterion value, re-take. Instructions.
As a result of this check, the guidance processor 24
When the acquired ultrasonic image is good, the image is stored in the storage medium 34, and when the acquired ultrasonic image is not good, an instruction to retake is given.

As described above, the operator can compare the model image with the image being photographed by himself during the scanning operation (see step S3). However, the operator may be uneasy based on his / her own judgment only as to whether or not the collected image appropriately displays the diagnosis target. The check function can support the operator in such a case. In other words, by using the subject's own judgment based on the model image and the judgment by the check function with respect to the collected ultrasonic image, it is possible to prevent a mistake in the imaging of the ultrasonic image. It is a function to do. In addition, when reacquiring an ultrasonic image, it is preferable that the step which is not appropriate in the above check is estimated, and the process is repeated from the corresponding step.

Next, the acquired ultrasonic image is output (step S5).

That is, the acquired ultrasonic image data is automatically stored in, for example, a filing system in a hospital or a hard disk in a computer of a diagnostic physician via the interface circuit 38 and a network as shown in FIG. Is done. This stored ultrasound image can be used for diagnosis later or attached to an electronic medical record. Needless to say, the image can be output as a photograph to a printer connected to a network or directly connected to the diagnostic apparatus 10. In the case where the image is transferred via a network, if the transferred image is output to a printer near the operator, it is possible to immediately confirm whether or not the operation was finally good. Further, the information on the electrocardiogram waveform and the body temperature measured in step S2 is transferred together with the diagnostic image.

The diagnosis based on the ultrasonic image photographed by the ultrasonic image diagnostic apparatus according to the present invention is performed by a doctor who is not at the place (imaging place). In other words, the subject and the place where the ultrasonic image is captured are not the same as the subject and the place where the diagnosis is performed based on the ultrasonic image. Therefore, it can be said that smooth connection during this period is one of the important issues when used in actual clinical settings. As described above, according to the ultrasonic diagnostic imaging apparatus of the present invention, since the configuration is such that the diagnostic image is automatically transferred to the diagnosis doctor, the imaging to the diagnosis can be smoothly performed without any gap. Can be.

At this time, a fee for use of the present diagnostic apparatus or a diagnostic fee according to the contents of a doctor's diagnosis performed at the image transfer destination is added to the subject (if the user and the subject are different, the User).

More specifically, information such as the use time, use mode, and use probe of the present system is transmitted by a service center (administrator of this system, doctor in charge, accounting department of hospital, service provider, manufacturer of this system) through a network. After-sales service center). On the other hand, the contents of the diagnosis or a specific diagnosis fee are sent from the hospital to the administrator, and the amount is withdrawn from an account contracted by the user based on the authentication ID registered in advance.

The above fee for use, diagnostic fee, account information,
The personal information such as the frequency of use is stored in the service center server,
It is preferable that the information is stored in the ultrasonic diagnostic apparatus and updated to the latest information as needed.

Computer software relating to the use of the present system via the network (for example, setting of a diagnostic protocol from the network, comments of doctors, the above-mentioned billing method, etc.) is set from the service center via the network as necessary. It is possible. In addition, from the viewpoint of further efficiency and safety, the software to be used is installed in the ultrasound diagnostic apparatus in advance, and can be used only when a program for starting the software is separately installed again, or a product ID. The software may be used only after a specific ID such as is input.

Finally, the guidance processor 24
The completion of the diagnosis is notified, and the removal of the electrocardiograph or the like is instructed by voice or the like (step S6).

The example of the operation related to the acquisition of the ultrasonic image according to the guidance function has been described above. This guidance function enables various guidance related to ultrasonic image diagnosis by storing a guidance program in the storage medium 34.

According to the configuration described above, the following effects can be obtained.

That is, since the configuration is such that the operation procedure relating to imaging or the operation method of the ultrasonic diagnostic imaging apparatus in each operation procedure is guided, appropriate ultrasonic imaging can be performed without performing special training. . In particular,
Since the guidance is provided by voice, real images, computer graphics, and the like, an easy-to-understand description can be provided.

Therefore, an appropriate ultrasonic image can be taken even by the subject or a person who has no experience. In addition, the effect can be expected also for the education of an inexperienced sonographer.

Further, setting a diagnostic protocol in the ultrasonic diagnostic apparatus from a remote service center, automatically paying a usage fee and the like to a remote service center,
Etc. are possible via a network. Therefore, it is possible to perform an economical and time-efficient diagnosis operation without requiring much manpower.

(Second Embodiment) Next, a second embodiment will be described. The above-described first embodiment is an ultrasonic image diagnosis installed in a relatively favorable imaging environment, such as in a hospital, where maintenance is always performed well, and an experienced medical technician is nearby. The device has been described. On the other hand, in the second embodiment, the system is installed in an environment where photographing problems are likely to occur, such as a home, a welfare facility for the elderly, and a clinic in a remote place. An ultrasonic diagnostic imaging apparatus having the above will be described.

FIG. 7 is a diagram showing a schematic configuration of an ultrasonic diagnostic imaging apparatus according to the second embodiment. The same components as those in FIG. 1 are denoted by the same reference numerals, and description thereof will be omitted.

Referring to FIG. 7, the ultrasonic diagnostic imaging apparatus according to the second embodiment further includes a gel tank 50, a lightweight sensor 52, a modem 53, a detector 55, and an authentication checker 57. And is communicable with the service center 62.

The gel tank 50 is a tank for storing an acoustic gel used for improving the acoustic matching between the probe 12 and the subject at the time of ultrasonic diagnosis. A measuring sensor 52 is connected to the gel tank 50 so that the remaining amount of the acoustic gel can be measured. Information from the weighing sensor 52 is sent to the guidance processor 24. When the remaining amount is small (for example, when the remaining amount is smaller than a certain reference amount), the guidance processor 24 displays a warning prompting gel replacement on the display unit 22.

The modem 53 transfers an ultrasonic image and other information obtained by using the telephone line 60 or the like to an external hospital or the like.

The detector 55 detects position information or acceleration information of the probe 12 and sends the result to the guidance processor 24.

The authentication checker 57 authenticates an individual at the time of using the device, and determines permission to use. The form of the authentication checker 57 is a magnetic reader in the case of a magnetic card. Further, physiological data such as a fingerprint and a voice print can be used as the authentication data. In these cases,
The authentication checker 57 is an optical reader for fingerprints, and a microphone for voice. The recognition software program is stored in the storage medium 34 for authentication and is activated by the guidance processor 24.

The service center 62 is provided with a computer capable of remotely operating the diagnostic device 10. By a remote operation from the service center 62, a guidance function of the diagnostic device 10 described later can be started, and an operation instruction regarding the diagnostic device 10 can be given to a subject at home or a facility for the aged.

Next, an ultrasonic image acquiring operation performed by the subject using the ultrasonic image diagnostic apparatus 10 configured as described above will be described with reference to FIG.

FIG. 8 is a flowchart showing an ultrasonic image acquiring operation performed by the subject.

First, on a predetermined photographing date or photographing time, the subject is informed that the examination time has come by an alarm sound from the speaker 26 or the like (step S11).

This alarm function is executed by the guidance processor 24 based on an examination schedule recorded in advance in the storage medium 34 in the diagnostic apparatus for each subject. With this alarm function, the subject can easily know the appropriate date and time for ultrasonic image capturing.
At the time of notification by alarm, the system may be automatically activated, but for safety only the time is notified,
It is desirable that the operator turn on the power manually.

Next, when the diagnostic apparatus is started, a switch input involving personal authentication (password authentication) is performed (step S1).
2).

[0091] The guidance processor 24 displays a guidance image for personal authentication on the display unit 22 and outputs guidance voice from the speaker 26. As a method of this personal authentication, input of a password and a password using an operation panel is generally considered.
7 may be used to read data of a personal ID card represented by a magnetic card. Further, a configuration may be adopted in which physiological data such as a fingerprint and a voiceprint is used as authentication data. As described above, the authentication checker 57
Is an optical reader for fingerprints and a microphone for audio.

Since the ultrasonic diagnostic imaging apparatus is a medical device, it is preferable that the ultrasonic diagnostic imaging apparatus has a security function such that only limited persons can use the apparatus in order to keep the data and functions held by the apparatus safe. According to the personal authentication function, the device can be used only when the device is authenticated, so that the security can be improved.

Next, a diagnosis protocol is selected (step S13). This diagnostic protocol is stored in the storage medium 34 in advance, and the guidance processor 2
4 is selected in the procedure described below. That is,
When performing a routine routine image acquisition for a subject, the guidance processor 24 loads the corresponding diagnostic protocol from the storage medium 34 based on the recognized personal ID. Also, when performing image acquisition different from the image acquisition of the above routine, for a new subject,
If it becomes necessary to execute a protocol that is not stored in the storage medium 34, or if it is necessary to make a doctor's decision every time, etc. Connect the line to and download the software that implements the appropriate protocol. In this case, it is preferable to be able to receive an e-mail or the like in which a comment of a doctor or the like is written.

According to such a configuration, even when imaging of a new subject or imaging different from normal imaging is performed, it can be executed according to an appropriate protocol.

Next, preparations for diagnosis are made (step S1).
4). The basic operation procedure is the same as that described in the first embodiment (see FIG. 2), so only the features of this embodiment will be described.

When the remaining amount of the gel sent from the weighing sensor 52 is equal to or less than the reference value, the guidance processor 24 instructs the replacement with a new gel. Further, for example, assuming use at home, the guidance processor 2
No. 4 may be configured to automatically connect a line to a service center or to issue an instruction for gel replenishment via the Internet.

[0097] Similarly, in the case where a system abnormality occurs, it is also preferable that the system be automatically connected to the service center and transmitted the status. These features
The guidance processor 24 can be realized by reading and executing a software program for executing the above contents stored in the storage medium 34.

The ultrasonic diagnostic imaging apparatus according to the second embodiment is installed in a home, a welfare facility for the elderly, and the like. When compared to devices used in hospitals, these locations generally do not have anyone who is familiar with the device, which may result in poor management of the device.
According to the above configuration, appropriate maintenance and quick response to a device abnormality can be performed in these places.

Next, scanning is started (step S1).
5). This is also substantially the same as step S2 of the first embodiment, and only the differences from the first embodiment will be described.

In general, at the time of scanning, the speed at which the probe 12 is moved differs depending on the diagnosis site.
