In the following embodiments, an ultrasonic diagnostic system including an ultrasonic diagnostic apparatus will be described as an example of a medical system.

(First embodiment)
First, an outline of the ultrasonic diagnostic system according to the present embodiment will be described. FIG. 1 is a diagram for explaining an overview of an ultrasonic diagnostic system 1 according to the first embodiment. Here, FIG. 1 shows an example in which the ultrasonic diagnostic system 1 according to the present embodiment is applied to a medical examination in obstetrics. Note that the ultrasonic diagnostic system 1 according to the present embodiment is not limited to medical examinations in obstetrics but can be applied to various other cases.

  As shown in FIG. 1, the ultrasound diagnostic system 1 includes an ultrasound diagnostic apparatus 100 and an information terminal 200, and the information terminal 200 is communicatively connected to a mobile terminal 300. The ultrasonic diagnostic apparatus 100 includes an ultrasonic probe, an input interface, a display, and an apparatus main body (console), and is communicatively connected to a network such as a hospital LAN (Local Area Network). In addition, the ultrasonic diagnostic apparatus 100 is connected to the information terminal 200 through a communication line different from the hospital LAN. Note that either a wired connection or a wireless connection may be used for the communication connection with the hospital LAN of the ultrasonic diagnostic apparatus 100 and the communication connection with the information terminal 200.

  The ultrasonic diagnostic apparatus 100 operates an ultrasonic probe by an operator, generates an ultrasonic image based on ultrasonic waves transmitted and received by the ultrasonic probe, and displays the generated ultrasonic image on a display. For example, as shown in FIG. 1, the ultrasound diagnostic apparatus 100 is used for obstetric medical examination, and generates and displays an ultrasound image of a fetus. In addition, the ultrasonic diagnostic apparatus 100 transmits image data such as an ultrasonic image to the information terminal 200 via a communication line different from the hospital LAN.

  The information terminal 200 is connected to the ultrasonic diagnostic apparatus 100 via a communication line different from the hospital LAN, and transmits and receives medical information. For example, the information terminal 200 receives image data such as an ultrasonic image from the ultrasonic diagnostic apparatus and stores the received image data. The information terminal 200 is, for example, a PC (Personal Computer) or a tablet PC. Here, when the function of the second console is applied to the ultrasound diagnostic system 1, the information terminal 200 accepts an operation for controlling the ultrasound diagnostic apparatus 100 and collects and collects ultrasound images. An ultrasonic image can be displayed.

  For example, the information terminal 200 receives various input operations for controlling the main body of the ultrasonic diagnostic apparatus 100 and collects ultrasonic images in the same manner as the input interface of the ultrasonic diagnostic apparatus 100. The apparatus main body of the diagnostic apparatus 100 is controlled. Then, the information terminal 200 receives the ultrasonic image collected by the ultrasonic diagnostic apparatus 100 and displays the received ultrasonic image on the display of the own apparatus or stores it in the storage circuit.

  Here, the information terminal 200 can be used at a position away from the ultrasonic diagnostic apparatus 100 by being connected to the ultrasonic diagnostic apparatus 100 by wireless communication, for example. Accordingly, the operator operates the ultrasonic diagnostic apparatus while observing the ultrasonic image displayed on the information terminal 200 even at a position where it is difficult to operate the console and the ultrasonic image in the ultrasonic diagnostic apparatus 100. be able to. For example, as shown in FIG. 1, the ultrasonic diagnostic apparatus 100 collects an ultrasound image of the abdomen of the subject by operating the information terminal 200 while scanning the abdomen of the subject lying on the side with an ultrasound probe. be able to.

  In addition, the information terminal 200 is connected to the mobile terminal 300 through a communication line different from the communication line for communication connection with the ultrasonic diagnostic apparatus 100 and transmits / receives various information to / from the mobile terminal 300. For example, the information terminal 200 transmits image data such as an ultrasonic image to the mobile terminal 300. For example, the information terminal 200 receives medical information such as a medical report from the mobile terminal 300 and stores the received medical information. Then, the information terminal 200 transmits medical information to the medical device. Note that communication between the information terminal 200 and the mobile terminal 300 will be described in detail later.

  The mobile terminal 300 is connected for communication with the information terminal 200 and receives an ultrasonic image. The portable terminal 300 is, for example, a PDA (Personal Digital Assistant) possessed by the subject, a tablet PC, a smartphone, or the like. For example, the mobile terminal 300 is a smartphone possessed by a subject who receives an obstetrical medical examination, and receives image data such as an ultrasound image of a fetus from the information terminal 200. Here, the mobile terminal 300 may be a device that cannot transmit and receive image data by short-range wireless communication such as Bluetooth (registered trademark), for example. In this case, for example, an OS (Operating System) may be an iOS. (Registered trademark).

  As described above, the ultrasound diagnostic system 1 transmits and receives medical information such as ultrasound images between the ultrasound diagnostic apparatus 100 and the information terminal 200, and transmits ultrasound images and the like to the portable terminal 300 via the information terminal 200. Send medical information. Here, when transferring an ultrasonic image to the mobile terminal 300 that cannot receive image data by short-range wireless communication, at present, image data can be received by installing a dedicated application on the mobile terminal 300. Although it becomes possible, it is troublesome to install an application in order to receive image data, and costs (communication charges) for downloading the application are required.

Furthermore, in the ultrasonic diagnostic system 1 according to the first embodiment, when the information terminal 200 is connected to the mobile terminal 300 for communication, the communication connection with the ultrasonic diagnostic apparatus 100 is interrupted, so that the subject is possessed. The portable terminal 300 is prevented from being connected to the ultrasonic diagnostic apparatus 100 or the hospital LAN via the information terminal 200. Thereby, the ultrasound diagnostic system 1 can also securely provide image data to the mobile terminal 300.

It is received by a plurality of piezoelectric vibrators 100a. The amplitude of the received reflected wave signal depends on the difference in acoustic impedance at the discontinuous surface where the ultrasonic wave is reflected.

Further, the transmission delay unit generates a delay time for each piezoelectric vibrator necessary for focusing the ultrasonic wave generated from the ultrasonic probe 100a into a beam and determining transmission directivity. Give for each rate pulse. The pulser applies a drive signal (drive pulse) to the ultrasonic probe 100a at a timing based on the rate pulse. That is, the transmission delay unit arbitrarily adjusts the transmission direction of the ultrasonic wave transmitted from the piezoelectric vibrator surface by changing the delay time given to each rate pulse.

  The transmission / reception circuit 110 has a function capable of instantaneously changing the transmission frequency, the transmission drive voltage, and the like in order to execute a predetermined scan sequence based on an instruction from the processing circuit 150 described later. In particular, the change of the transmission drive voltage is realized by a linear amplifier type transmission circuit capable of instantaneously switching the value or a mechanism for electrically switching a plurality of power supply units.

  The transmission / reception circuit 110 includes a preamplifier, an A / D (Analog / Digital) converter, a reception delay unit, an adder, and the like.

  The Doppler processing circuit 130 includes an MTI filter and a blood flow information generation unit, and executes, for example, a color Doppler method to calculate blood flow information. In the color Doppler method, transmission / reception of ultrasonic waves is performed a plurality of times on the same scanning line, and an MTI (Moving Target Indicator) filter is applied to a data string at the same position, so that a stationary tissue or movement A signal derived from a blood flow is extracted by suppressing a signal derived from a slow tissue (clutter signal). In the color Doppler method, blood flow information such as blood flow velocity, blood flow dispersion, and blood flow power is estimated from the blood flow signal.

  The MTI filter outputs a data sequence in which clutter components are suppressed and a blood flow signal derived from blood flow is extracted from a data sequence of continuous reflected wave data at the same position (same sample point) using a filter matrix. To do. The blood flow information generation unit performs calculation such as autocorrelation calculation using data output from the MTI filter, estimates blood flow information, and outputs the estimated blood flow information as Doppler data.

  The authentication information display function 155 presents identification information for operating the ultrasonic diagnostic apparatus 100 by the information terminal 200. For example, the authentication information display function 155 displays identification information including the SSID and password set by the access point function 154 on the display 100c. Here, the password included in the identification information is a predetermined character, symbol, or number for authenticating whether or not the operator is a valid user who operates the ultrasonic diagnostic apparatus 100 by the information terminal 200. It is an enumeration. Therefore, the password may be different from the password set by the access point function 154, but in this case as well, the password is used for each communication connection between the ultrasonic diagnostic apparatus 100 and the information terminal 200 or periodically. It is a one-time password that is updated to In addition, although SSID and the password were mentioned as an example as identification information, the case where ID and password different from SSID are used as identification information may be sufficient.

  The authentication function 156 authenticates the received response data when receiving response data from the information terminal 200 in response to the password input request transmitted from the access point function 154. Specifically, the authentication function 156 receives response data corresponding to a password input request from the information terminal 200 via the communication interface 160. Then, the authentication function 156 compares the password included in the received response data with the password displayed by the authentication information display function 155. Here, the authentication function 156 permits the operator to operate the ultrasonic diagnostic apparatus 100 using the information terminal 200 when the password included in the response data matches the password displayed by the authentication information display function 155. To do.

  The encoding function 157 compresses the ultrasonic image generated by the image generation function 152 and the screen data acquired from the storage circuit 140 by the screen generation function 153. For example, the encoding function 157 compresses the ultrasonic image using a compression technique such as JPEG (Joint Photographic Experts Group). Further, for example, the encoding function 157 compresses the screen data including the accompanying information using a compression technique such as MPEG (Moving Picture Experts Group).

  The control function 151 transmits the ultrasonic image and screen data compressed by the encoding function 157 to the information terminal 200 via the communication interface 160. For example, the control function 151 transmits the screen data generated and compressed in response to the command signal transmitted by the information terminal 200 to the information terminal 200. Further, for example, the control function 151 transmits an ultrasonic image collected and compressed by the operator operating the information terminal 200 to the information terminal 200.

For example, the storage circuit 22 stores an ultrasound image received from the ultrasound diagnostic apparatus 100 and screen data. Further, for example, the storage circuit 22 stores a processing result by the processing circuit 25. For example, the storage circuit 22 is implemented by a RAM (Random Access Memory), a semiconductor memory device such as a flash memory, a hard disk, or an optical disk.

  Note that data stored in the storage circuit 22 can be transferred to an external device via a communication line. For example, data stored in the storage circuit 22 can be transferred to the mobile terminal 300 via a communication line different from the communication line with the ultrasonic diagnostic apparatus 100. Note that the storage form in the storage circuit 22 may be stored temporarily for live information or for long-term recording.

  The input interface 23 includes a trackball for performing an input operation, a switch button, a mouse, a keyboard, a touch pad for performing an input operation by touching an operation surface, a touch monitor in which a display screen and a touch pad are integrated, and an optical sensor.

The input interface 23 is connected to the processing circuit 25, converts the input operation received from the operator into an electrical signal, and outputs it to the processing circuit 25. In this specification, the input interface 23 is not limited to the one having physical operation parts such as a mouse and a keyboard. For example, an example of the input interface includes an electric signal processing circuit that receives an electric signal corresponding to an input operation from an external input device provided separately from the apparatus and outputs the electric signal to the processing circuit 25.

  The display 24 displays a GUI (Graphical User Interface) for the operator of the information terminal 200 to input various requests using the input interface 23, and notifies the operator of the processing result of the processing circuit 25 and the like. Various messages and display information are displayed. The display 24 displays screen data received from the ultrasonic diagnostic apparatus 100, an ultrasonic image, and the like. For example, the display 24 is a liquid crystal display, an OLED (Organic Light Emitting Diode) display, or the like. If the information terminal 200 is a tablet PC, the display 24 is integrated with the input interface 23. The display 24 also has a speaker and can output sound.

  The processing circuit 25 controls the entire processing of the information terminal 200. Specifically, the processing circuit 25 controls various processes based on various setting requests input from the operator via the input interface 23 and various control programs and various data read from the storage circuit 22. For example, the processing circuit 25 controls the display 24 to display an ultrasonic image or the like stored in the storage circuit 22. For example, the processing circuit 25 establishes a communication connection with the mobile terminal 300 and transmits / receives various data to / from the mobile terminal 300.

  The processing circuit 25 executes a control function 251, an image processing function 252, an access point function 253, a server function 254, an encoding function 255, an authentication function 256, and a security processing function 257.

  Here, for example, the control function 251, image processing function 252, access point function 253, server function 254, encoding function 255, authentication function 256, and security processing function 257 that are constituent elements of the processing circuit 25.

The processing circuit 25 is a processor that realizes a function corresponding to each program by reading each program from the storage circuit 22 and executing the program. In other words, the processing circuit 25 in a state where each program is read has each function shown in the processing circuit 25.

  The control function 251 controls the entire information terminal 200. For example, the control function 251 controls transmission / reception of various data to / from the ultrasonic diagnostic apparatus 100 via the communication interface 21. For example, the control function 251 transmits the identification information used for authentication for operating the ultrasonic diagnostic apparatus 100 by the information terminal 200 to the ultrasonic diagnostic apparatus 100 and screen data from the ultrasonic diagnostic apparatus 100. And reception of ultrasonic images.

  Further, the control function 251 performs control so that the screen data received from the ultrasonic diagnostic apparatus 100 and the ultrasonic image are displayed on the display 24. In addition, when an input operation to a function button or panel switch included in the screen data is executed, the control function 251 specifies a function corresponding to the operated function button or panel switch based on the incidental information. Then, the control function 251 generates a command signal for the identified function and performs control so as to transmit the generated command signal to the ultrasonic diagnostic apparatus 100. Furthermore, the control function 251 executes processing based on the response data received from the ultrasound diagnostic apparatus 100 in response to the command signal. For example, when a command signal for changing the operation screen is transmitted, the control function 251 controls the display 24 to display the received screen data according to the command signal.

  The control function 251 controls transmission of image data to the mobile terminal 300. Specifically, the transmission of the image data to the portable terminal 300 with which the communication connection has been established is controlled by processing by other functions in the processing circuit 25, which will be described in detail later.

  As described above, in the ultrasonic diagnostic system 1 according to the first embodiment, the ultrasonic diagnostic apparatus 100 and the information terminal 200 are connected to communicate and transmit / receive various data. Here, since the second console is applied to the ultrasound diagnostic system 1, the ultrasound diagnostic apparatus 100 can be operated by the information terminal 200.

  For example, the information terminal 200 displays the screen data received after the communication connection with the ultrasonic diagnostic apparatus 100 is established on the display 24, thereby performing operations in which various function buttons are arranged as shown in FIG. A screen can be displayed. In addition, the information terminal 200 can display an ultrasound image of a fetus, for example, as illustrated in FIG. 4 by displaying the ultrasound image received from the ultrasound diagnostic apparatus 100 on the display 24. Here, when the second console functions in the ultrasonic diagnostic system 1, the ultrasonic image being collected is transmitted to the information terminal 200 in real time. That is, the operator can scan the abdomen of the subject with the ultrasonic probe 100a while confirming the collected ultrasonic images in real time on the display 24 of the information terminal 200. FIG. 4 is a diagram illustrating an example of display on the information terminal 200 according to the first embodiment.

  Here, in the ultrasound diagnostic system 1 according to the first embodiment, the image data handled in the ultrasound diagnostic system 1 is processed by the subject by the processing of the processing circuit 25 of the information terminal 200 described in detail below. It is possible to easily provide the mobile terminal 300 to the user. Specifically, the ultrasound diagnostic system 1 can easily provide image data to the portable terminal 300 that cannot receive image data by short-range wireless communication. Details of the processing by the processing circuit 25 will be described below. In the following, an ultrasonic image that can be provided from the information terminal 200 to the mobile terminal 300, screen data, and the like are collectively referred to as image data.

  Returning to FIG. 3, the image processing function 252 executes various image processing on the ultrasound image received from the ultrasound diagnostic apparatus 100 and screen data. For example, the image processing function 252 executes image processing for deleting personal information included in screen data or ultrasonic images transferred to the mobile terminal 300. For example, the image processing function 252 removes or fills the area of personal information included in the ultrasonic image. That is, the information terminal 200 controls to provide the portable terminal 300 in an anonymized state.

  Here, the image data to be transferred to the portable terminal 300 can be determined at various timings. For example, after a series of examinations are completed, a plurality of collected ultrasonic images may be determined while being displayed on the information terminal 200, or when scanning with the ultrasonic probe 100a, the information terminal 200 is in real time. It may be determined from the ultrasonic image displayed at In addition, when determining an ultrasound image to be transferred from a plurality of collected ultrasound images after a series of examinations is completed, the timing is before the start button for starting the transfer is pressed. The timing may be determined at any timing. In addition, when the ultrasound image to be transferred is determined from the collected plurality of ultrasound images after the series of examinations is completed, a plurality of ultrasound images may be selected as the ultrasound images to be transferred. .

  Note that the image processing function 252 can appropriately perform other image processing such as enlargement / reduction of image data and extraction of a region of interest in an ultrasonic image, as well as the above-described anonymization processing of image data.

  The access point function 253 is a software AP function that generates a virtual access point for the information terminal 200 to communicate with the mobile terminal 300. Specifically, when a transfer button for transferring image data to the portable terminal 300 is pressed, the access point function 253 controls the communication interface 21 to generate a virtual access point. Here, the transfer button is provided on, for example, a touch panel of the input interface 23, and is pressed after image data to be transferred to the mobile terminal 300 is determined.

  Here, the access point function 253 sets an SSID and a password when generating an access point. The SSID and password may be set manually by the operator through the input interface 23, or may be set automatically. Here, the password is a one-time password that is updated every communication connection between the information terminal 200 and the portable terminal 300 or periodically.

  Then, the access point function 253 establishes a communication connection between the information terminal 200 and the mobile terminal 300 when the communication connection of the mobile terminal 300 to the information terminal 200 is permitted in an authentication process by the authentication function 256 described later. The authentication process by the authentication function 256 will be described in detail later.

  Here, as described above, when the information terminal 200 and the portable terminal 300 are connected for communication, in the ultrasonic diagnostic system 1, the communication connection between the information terminal 200 and the ultrasonic diagnostic apparatus 100 is disconnected. That is, the ultrasonic diagnostic system 1 invalidates the communication connection between the information terminal 200 and the ultrasonic diagnostic apparatus 100 before the information terminal 200 and the mobile terminal 300 are connected for communication. For example, when the transfer button is pressed, the control function 251 controls to disconnect the communication connection established with the ultrasound diagnostic apparatus 100. Thereby, it is possible to avoid the portable terminal 300 owned by the subject being connected to the ultrasonic diagnostic apparatus 100 or the hospital LAN.

  The encoding function 255 encodes various information. Specifically, the encoding function 255 encodes information related to image data transfer to the mobile terminal 300 into a code that can be decoded by the mobile terminal 300. For example, the encoding function 255 converts the SSID and password set by the access point function 253 into a two-dimensional code as shown in FIG. Further, for example, the encoding function 255 causes the storage destination information of the image data to be transferred to the mobile terminal 300 to be two-dimensionally encoded. FIG. 5 is a diagram illustrating an example of processing by the encoding function 255 according to the first embodiment.

  As described above, in the information terminal 200, when the transfer button for transferring image data to the portable terminal 300 is pressed, the access point function 253 generates an access point and sets an SSID and a password. . When the encoding function 255 converts the SSID and password set by the access point function 253 into a two-dimensional code, the control function 251 displays the two-dimensional code on the display 24.

  The subject operates his / her portable terminal 300 to read the two-dimensional code displayed on the display 24 with the camera. Thereby, the portable terminal 300 acquires the SSID and password of the virtual access point. When the SSID and password are acquired, the mobile terminal 300 transmits the acquired SSID and password and authentication information such as the MAC address of the own device to the information terminal 200, thereby establishing a communication connection between the information terminal 200 and the mobile terminal 300. Do. The transmission of the authentication information may be performed automatically in response to the reading of the two-dimensional code, or the portable terminal 300 displays a message indicating that the communication connection with the information terminal 200 is performed, and the subject It may be performed by executing an operation that agrees to establish a communication connection with the information terminal 200.

  The authentication function 256 performs authentication for authentication information received from the mobile terminal 300. Specifically, the authentication function 256 receives authentication information from the mobile terminal 300 via the communication interface 21. Then, the authentication function 256 compares the password included in the received authentication information with the two-dimensional encoded password. Here, the authentication function 256 permits communication connection between the portable terminal 300 and the information terminal 200 when the password included in the authentication information matches the two-dimensionally encoded password. Here, when the communication connection of the mobile terminal 300 to the information terminal 200 is permitted, the access point function 253 establishes the communication connection between the information terminal 200 and the mobile terminal 300.

  The server function 254 returns a response to the image data browsing request from the mobile terminal 300. For example, the server function 254 functions as a Web server using HTTP (Hypertext Transfer Protocol), and sends an HTTP request for browsing a storage destination URL (Uniform Resource Locator) storing image data to the Web of the mobile terminal 300. Receive from browser. Then, the server function 254 returns image data to the Web browser of the mobile terminal 300 in response to the received HTTP request.

  For example, first, when the transfer button is pressed, the server function 254 is determined to transfer to the mobile terminal 300 and the image data subjected to image processing is stored in the temporary storage area of the storage circuit 22. The encoding function 255 is notified of the stored URL. Here, each time the transfer button is pressed, the server function 254 changes the file name of the image data using the GUID (Globally Unique Identifier) of the image data, the time when stored in the storage circuit 22, and the like. The URL is updated every time.

  When the URL is notified from the server function 254, the encoding function 255 converts the notified URL into a two-dimensional code. Here, the URL notified to the encoding function 255 is updated every time the transfer button is pressed. That is, the URL encoded by the encoding function 255 becomes a different code for each transfer. Then, when the encoding function 255 converts the URL into a two-dimensional code, the control function 251 displays the two-dimensional code on the display 24. In the above-described example, the case where the code is changed for each transfer by updating the URL each time the transfer button is pressed has been described, but the embodiment is not limited thereto. For example, the encoding function 255 can change the code by encoding the notified URL by a different encoding method. For example, the encoding function 255 causes the URL to be two-dimensionally encoded by a different encoding method each time a communication connection between the information terminal 200 and the portable terminal 300 is established.

  The subject operates his / her portable terminal 300 to read the two-dimensional code displayed on the display 24 with the camera. Thereby, the portable terminal 300 acquires the URL of the image data. When the URL of the image data is acquired, the mobile terminal 300 transmits an HTTP request for browsing the URL acquired by the Web browser to the information terminal 200. The server function 254 transfers the requested URL image data to the web browser of the mobile terminal 300 in response to the HTTP request received from the mobile terminal 300. The web browser may be activated on the mobile terminal 300 automatically when the two-dimensional URL code is read. Alternatively, the mobile terminal 300 may display a message to activate the web browser and display the message. It may be performed by executing an operation in which the sample agrees to start the Web browser.

  Then, when the image data is transferred from the information terminal 200, the mobile terminal 300 can display an ultrasound image of the fetus with a Web browser, for example, as shown in FIG. Here, the subject can store the fetal ultrasound image in the portable terminal 300 by executing an operation for storing the image data in the Web browser. Here, as shown in FIG. 6, the image data transferred to the mobile terminal 300 is such that the personal information is concealed by the processing of the image processing function 252. FIG. 6 is a diagram illustrating an example of displaying an ultrasonic image on the mobile terminal 300 according to the first embodiment.

  As described above, when the transfer of the image data to the mobile terminal 300 is completed, the operator performs an operation for disconnecting the communication connection between the information terminal 200 and the mobile terminal 300. For example, the information terminal 200 displays a communication end button for canceling the communication connection on the touch panel. The operator disconnects the communication connection between the information terminal 200 and the portable terminal 300 by pressing a communication end button shown on the touch panel of the information terminal 200.

  Returning to FIG. 3, the security processing function 257 performs a virus check on the information terminal 200. For example, the security processing function 257 performs a virus check on the information terminal 200 that has completed the communication connection with the mobile terminal 300 based on the virus definition file. Here, when a virus is detected, the security processing function 257 removes the detected virus.

  When the virus check by the security processing function 257 is completed, the control function 251 transmits a communication connection request to the ultrasonic diagnostic apparatus 100, so that the communication connection with the ultrasonic diagnostic apparatus 100 is established again.

  As described above, in the ultrasonic diagnostic system 1, the subject can transfer image data to his / her portable terminal 300 only by reading the two-dimensional code twice with his / her portable terminal 300. Image data can be provided easily. In the ultrasound diagnostic system 1, when transferring image data, a communication line using a virtual access point is constructed, and the image data is transferred using the constructed communication line, so that the operator can use a dedicated communication line. Desired image data can be obtained without incurring a communication fee for downloading the application.

  Further, in the ultrasonic diagnostic system 1, when the information terminal 200 is connected to the mobile terminal 300 for communication, the communication connection between the information terminal 200 and the ultrasonic diagnostic apparatus 100 is disconnected to provide image data to the mobile terminal 300. Can be performed securely.

  Next, the flow of processing in the ultrasonic diagnostic system 1 according to the first embodiment will be described. FIG. 7 is a sequence diagram showing the flow of processing in the ultrasonic diagnostic system 1 according to the first embodiment. Here, FIG. 7 shows a case where a second console is applied to the ultrasonic diagnostic system 1.

  As shown in FIG. 7, in the ultrasound diagnostic system 1, when the ultrasound diagnostic apparatus 100 accepts pressing of the second console start button for starting the second console (step S101), a virtual access point is created. Then, the communication connection with the information terminal 200 is established, and the authentication information is displayed (step S102). Further, the ultrasonic diagnostic apparatus 100 transmits an authentication information input request for operating the ultrasonic diagnostic apparatus 100 from the information terminal 200 to the information terminal 200.

  Upon receiving the authentication information input request, the information terminal 200 receives the authentication information input displayed on the ultrasonic diagnostic apparatus 100, and transmits the authentication information to the ultrasonic diagnostic apparatus 100 (step S103). When receiving the authentication information from the information terminal 200, the ultrasound diagnostic apparatus 100 executes the authentication process by comparing the received authentication information with the displayed authentication information (step S104). When the authentication information matches in this authentication process, in the ultrasonic diagnostic system 1, remote operation of the ultrasonic diagnostic apparatus 100 by the information terminal 200 is started.

  Thereafter, when the information terminal 200 accepts pressing of the communication start button with the mobile terminal 300 (step S105), the information terminal 200 cuts off the communication connection with the ultrasonic diagnostic apparatus 100 and creates a virtual access point. Then, the authentication information is encoded and displayed (step S106). The portable terminal 300 acquires the authentication information by reading the encoded authentication information, and transmits the acquired authentication information to the information terminal 200 (step S107).

  When receiving the authentication information from the mobile terminal 300, the information terminal 200 executes the authentication process by comparing the received authentication information with the encoded authentication information (step S108). When the authentication information matches in this authentication process, the ultrasonic diagnostic system 1 starts communication connection between the information terminal 200 and the portable terminal 300.

  Further, the information terminal 200 encodes and displays the storage destination address of the image data to be transferred (step S109). The portable terminal 300 acquires the address of the image data by reading the encoded address, and transmits a browsing request for the acquired address to the information terminal 200 (step S110). When receiving the browsing request from the mobile terminal 300, the information terminal 200 transmits an image corresponding to the request (data stored at the address) to the mobile terminal 300 (step S111).

  When receiving the image from the information terminal 200, the portable terminal 300 accepts an operation from the subject and stores the image in its own device (step S112). Thereafter, when the information terminal 200 receives a press of a communication end button for ending communication with the mobile terminal 300 (step S113), the information terminal 200 cuts off the connection with the mobile terminal 300 and executes a virus check ( Step S114). After the virus check, the information terminal 200 resumes communication connection with the ultrasonic diagnostic apparatus 100.

  Next, a processing procedure by the information terminal 200 according to the first embodiment will be described. FIG. 8 is a flowchart showing a processing procedure of the information terminal 200 according to the first embodiment. FIG. 8 shows processing of the information terminal 200 after the communication connection with the ultrasonic diagnostic apparatus 100 is established.

  Steps S201, 202, 205, 209, and 212 in FIG. 8 are realized, for example, when the processing circuit 25 reads a program corresponding to the control function 251 from the storage circuit 22 and executes it. Further, step S203 is realized, for example, when the processing circuit 25 reads a program corresponding to the access point function 253 from the storage circuit 22 and executes it. Further, step S204 is realized, for example, when the processing circuit 25 reads a program corresponding to the encoding function 255 from the storage circuit 22 and executes it. Steps S206 and S207 are realized, for example, when the processing circuit 25 reads a program corresponding to the authentication function 256 from the storage circuit 22 and executes it. Further, step S208 is realized, for example, when the processing circuit 25 reads out a program corresponding to the image processing function 252 and a program corresponding to the encoding function 255 from the storage circuit 22 and executes them. Steps S210 and 211 are realized, for example, when the processing circuit 25 reads a program corresponding to the server function 254 from the storage circuit 22 and executes it. Further, step S213 is realized, for example, when the processing circuit 25 reads a program corresponding to the security processing function 257 from the storage circuit 22 and executes it.

  In the information terminal 200 according to the present embodiment, as illustrated in FIG. 8, the processing circuit 25 determines whether or not a button for starting communication with the mobile terminal 300 has been pressed (Step S <b> 201). Here, when the button is pressed by the subject (Yes at Step S201), the processing circuit 25 cuts off the communication connection with the ultrasonic diagnostic apparatus 100 (Step S202) and creates an access point (Step S203). . Note that the information terminal 200 continues the communication connection with the ultrasound diagnostic apparatus 100 until the button for starting communication with the mobile terminal 300 is pressed (No at Step S201).

  Then, the processing circuit 25 encodes the authentication information including the SSID and password of the access point (step S204), displays the code obtained by the encoding on the display 24 (step S205), and displays the encoded authentication information. It is determined whether it has been accepted (step S206). When the authentication information is accepted (Yes at Step S206), the processing circuit 25 further determines whether or not the authentication is OK (Step S207).

  Here, when the authentication by the received authentication information is OK (Yes at Step S207), the processing circuit 25 encodes the address of the storage destination of the image data in which the personal information is concealed (Step S208). The code obtained by the above is displayed on the display 24 (step S209).

  Thereafter, the processing circuit 25 determines whether or not a browsing request for the encoded address has been received (step S210). Here, when the browsing request is received (Yes at Step S210), the processing circuit 25 transmits the image data corresponding to the received address to the portable terminal 300 (Step S211), and determines whether or not the communication end button has been pressed. Determination is made (step S212). Thereafter, when the communication end button is pressed (Yes at Step S212), the processing circuit 25 executes a virus check of the information terminal 200 and resumes communication connection with the ultrasonic diagnostic apparatus 100 (Step S213).

  As described above, according to the ultrasonic diagnostic system 1 according to the first embodiment, the ultrasonic diagnostic apparatus 100 acquires an ultrasonic image. The information terminal 200 connected to the ultrasound diagnostic apparatus 100 stores the ultrasound image transferred from the ultrasound diagnostic apparatus 100, has an access point function, and displays a first code including access point identification information To do. The information terminal 200 is connected to the mobile terminal 300 that has read the first code via a network, and transfers the stored ultrasonic image to the mobile terminal 300 via the network. Therefore, the ultrasonic diagnostic system 1 according to the first embodiment makes it possible to easily provide the mobile terminal 300 with the image data acquired by the ultrasonic diagnostic apparatus 100.

  Further, according to the first embodiment, the first code includes a password corresponding to the identification information. Therefore, the ultrasonic diagnostic system 1 according to the first embodiment can save the trouble of inputting the password by the subject who owns the portable terminal 300, and can provide image data more easily.

  Further, according to the first embodiment, the information terminal 200 displays the second code including the information of the storage destination of the ultrasonic image, and when the mobile terminal 300 reads the second code, the information terminal 200 transmits the second code via the network. Then, the stored ultrasonic image is transferred to the portable terminal 300. Therefore, the ultrasound diagnostic system 1 according to the first embodiment can save the trouble of inputting the information of the storage destination of the image data by the subject who owns the portable terminal 300, and provides the image data more easily. Make it possible.

In addition, for example, the information terminal 200 can transfer image data in a state in which a pictogram or a body mark added to the ultrasound image is added to the mobile terminal 300 in the own device. In such a case, the image processing function 252 generates the above-described image data.

  Further, the information terminal 200 can transfer image data to which information is further added at the time of image data transfer. For example, the information terminal 200 can transfer, to the portable terminal 300, image data obtained by combining an image captured by a camera provided in the apparatus with an ultrasonic image. FIG. 9 is a diagram illustrating an example of image data according to the second embodiment. For example, as illustrated in FIG. 9, the information terminal 200 can transmit, to the mobile terminal 300, image data in which a mother's face photograph is combined with a fetal ultrasound image. In such a case, first, the operator operates the information terminal 200 to take a picture of the mother's face. Thereafter, the image processing function 252 generates image data obtained by combining the photographed mother's face photograph with an ultrasonic image. Here, the image processing function 252 synthesizes the mother's face photograph at a position that does not overlap the fetal region in the ultrasonic image, for example. As described above, in the ultrasonic diagnostic system 1 according to the second embodiment, image data obtained by adding information to an ultrasonic image can be transferred. Therefore, the ultrasonic diagnostic system 1 can provide various information to the mobile terminal 300.

That is, the information terminal 200 performs authentication processing using a password after communication connection with the mobile terminal 300 that has read the code obtained by encoding the access point authentication information, and the mobile terminal 300 that is permitted in the authentication processing. Transfer image data.

  In such a case, for example, when a browsing request is received by the server function 254, the control function 251 causes the display 24 to display a one-time password. The server function 254 transmits image data corresponding to the browsing request to the mobile terminal 300 only when a password that matches the one-time password displayed on the display 24 is received from the mobile terminal 300. Thereby, the ultrasound diagnosis system 1 can provide more secure image data.

  In the above-described embodiment, the case where the second console is applied to the ultrasonic diagnostic system 1 has been described as an example. However, the embodiment is not limited to this, and can be applied to any system as long as it is a system in which the ultrasonic diagnostic apparatus 100 and the information terminal are communicatively connected.

  In the above-described embodiment, the case where the information terminal 200 executes invalidation (blocking) of the communication connection between the ultrasound diagnostic apparatus 100 and the information terminal 200 has been described. However, the embodiment is not limited to this, and may be invalidated by the ultrasonic diagnostic apparatus 100, for example. In such a case, when the ultrasound diagnostic apparatus 100 receives from the information terminal 200 a notification indicating that the button for starting the communication connection with the portable terminal 300 has been pressed, the ultrasonic diagnostic apparatus 100 communicates with the information terminal 200. Disable.

  In the above-described embodiment, the case where the information terminal 200 transfers image data has been described. However, the embodiment is not limited to this. For example, the image data may be transferred by an ultrasonic diagnostic apparatus. That is, the ultrasound diagnostic apparatus 100 acquires an ultrasound image, stores the ultrasound image, has a function of an access point, displays a code including access point identification information, and a terminal and a network that read the code The connected ultrasonic image is transferred to the portable terminal 300 via the network.

  In such a case, the processing circuit 150 in the ultrasound diagnostic apparatus 100 executes the control function 251, the image processing function 252, the access point function 253, the server function 254, the encoding function 255, the authentication function 256, and the security processing function 257. . Here, when the ultrasound diagnostic apparatus 100 transfers image data to the portable terminal 300, the communication connection with the hospital LAN of the ultrasound diagnostic apparatus 100 is invalidated and the communication connection with the portable terminal 300 is cut off. The communication connection with the hospital LAN is reestablished.

  In the above-described embodiment, the ultrasonic diagnostic system 1 including the ultrasonic diagnostic apparatus has been described as an example of the medical system. However, the embodiment is not limited to this. For example, the above-described medical information transfer method is a system such as PACS (Picture Archiving and Communication Systems), HIS (Hospital Information Systems), or RIS (Radiology Information Systems). It may be applied to.

  In such a case, for example, a processing circuit in an information processing device such as a server device or a workstation included in the system described above executes the same processing as the processing by the processing circuit 150 described above, so that the information terminal 200, A communication connection is established with the portable terminal 300 to transmit / receive medical information such as image data and medical reports held in the system.

  For example, the above-described medical information transfer method may be applied to a system including other modalities such as an X-ray CT (Computed Tomography) apparatus or an MRI (Magnetic Resonance Imaging) apparatus. In such a case, for example, a processing circuit in a modality console device or a gantry executes the same processing as the processing by the processing circuit 150 described above, so that communication connection is established between the information terminal 200 and the portable terminal 300. Then, medical information such as image data held in each modality is transmitted and received.

  In the above-described embodiment, the case has been described in which image data is transferred from a medical apparatus such as the ultrasonic diagnostic apparatus 100 to the information terminal, and the image data is transferred from the information terminal 200 to the portable terminal 300. However, the embodiment is not limited to this. For example, medical information such as image data and a medical report is transferred from the mobile terminal 300 to the information terminal 200, and the medical information is transferred from the information terminal 200 to the medical device. May be.

  Thereby, for example, the portable terminal 300 storing image data handed over between hospitals at the time of transfer, medical reports, vital data acquired by the subject on a daily basis, and the like is transferred to the medical device in the hospital via the information terminal 200. Medical information such as image data and medical reports can be transferred securely and easily. For example, when a subject is transferred, medical information is transferred to the portable terminal 300 of the subject from the medical device of the hospital at the transfer source by the method described above. Then, the medical information is transferred from the portable terminal 300 of the subject to the medical device of the hospital at the transfer destination. Here, by using the transfer method of the present application, medical information can be transferred securely and easily. Hereinafter, transfer of medical information from the mobile terminal 300 will be described.

  In such a case, for example, when a button for receiving medical information such as image data or a medical report is pressed from the mobile terminal 300 in the information terminal 200, the access point function 253 generates an access point, Set the SSID and password. Then, the encoding function 255 converts the set SSID and password into a two-dimensional code. Thereafter, the control function 251 displays the two-dimensional code on the display 24.

  The subject operates his / her portable terminal 300 to read the two-dimensional code displayed on the display 24 with the camera. Thereby, the portable terminal 300 acquires the SSID and password of the virtual access point. When the SSID and password are acquired, the mobile terminal 300 transmits the acquired SSID and password and authentication information such as the MAC address of the own device to the information terminal 200, thereby establishing a communication connection between the information terminal 200 and the mobile terminal 300. Do.

  The authentication function 256 performs authentication for authentication information received from the mobile terminal 300. Specifically, the authentication function 256 receives authentication information from the mobile terminal 300 via the communication interface 21. Then, the authentication function 256 compares the password included in the received authentication information with the two-dimensional encoded password. Here, the authentication function 256 permits communication connection between the portable terminal 300 and the information terminal 200 when the password included in the authentication information matches the two-dimensionally encoded password. Here, when the communication connection of the mobile terminal 300 to the information terminal 200 is permitted, the access point function 253 establishes the communication connection between the information terminal 200 and the mobile terminal 300.

  Here, as described above, when the information terminal 200 and the mobile terminal 300 are connected for communication, the communication connection between the information terminal 200 and the medical device is disconnected. In other words, the medical device or information terminal 200 disables the communication connection between the information terminal 200 and the medical device before the information terminal 200 and the portable terminal 300 are connected by communication.

  The server function 254 returns a response to a request for uploading medical information such as image data or a medical report from the mobile terminal 300. For example, the server function 254 functions as a Web server and receives an HTTP request for browsing the URL of the upload screen from the Web browser of the mobile terminal 300. Then, the server function 254 returns an upload screen to the Web browser of the mobile terminal 300 in response to the received HTTP request.

  For example, when the button for receiving medical information such as image data or a medical report from the portable terminal 300 is pressed, the server function 254 first encodes the URL in which the upload screen is stored. 255 is notified. The encoding function 255 converts the notified URL into a two-dimensional code. Then, when the encoding function 255 converts the URL into a two-dimensional code, the control function 251 displays the two-dimensional code on the display 24.

  The subject operates his / her portable terminal 300 to read the two-dimensional code displayed on the display 24 with the camera. Thereby, the mobile terminal 300 acquires the URL of the upload screen. When the URL of the upload screen is acquired, the mobile terminal 300 transmits an HTTP request for browsing the URL acquired by the Web browser to the information terminal 200. In response to the HTTP request received from the mobile terminal 300, the server function 254 transfers the requested URL upload screen to the Web browser of the mobile terminal 300.

  Then, when the upload screen is transferred from the information terminal 200, the mobile terminal 300 can display the upload screen with a Web browser, for example. Here, the subject performs an operation for uploading medical information such as image data and medical reports in the mobile terminal 300 on the upload screen in the Web browser, so that the mobile terminal 300 performs medical information on the information terminal 200. Can be uploaded. The information terminal 200 stores all uploaded medical information in the storage circuit 22.

  When the upload of all medical information from the mobile terminal 300 is completed, the operator performs an operation for disconnecting the communication connection between the information terminal 200 and the mobile terminal 300. For example, the information terminal 200 displays a communication end button for canceling the communication connection on the touch panel. The operator disconnects the communication connection between the information terminal 200 and the portable terminal 300 by pressing a communication end button shown on the touch panel of the information terminal 200.

  Thereafter, when the virus check by the security processing function 257 is completed, the control function 251 transmits a communication connection request to the medical device, thereby establishing a communication connection with the medical device. The communication connection between the medical apparatus and the information terminal 200 is performed in the same manner as the communication connection between the ultrasonic diagnostic apparatus 100 and the information terminal 200 described above.

  When the communication connection between the medical device and the information terminal 200 is established, the operator operates the medical device to open the subject data. For example, the operator opens a screen for registering information on the subject, an examination data input screen, an electronic medical record, and the like. When the operator performs an operation on the medical device to acquire medical information such as image data of the subject and medical report stored in the information terminal 200, the processing circuit in the medical device A request for transfer of medical information is transmitted to 200. When the medical information transfer request is received from the medical device, the control function 251 of the information terminal 200 transmits the medical information or the compressed medical information to the medical device.

  When the medical information is received from the information terminal 200, the processing circuit in the medical device stores the received medical information in its own storage circuit. Here, the processing circuit in the medical apparatus stores an identifier or the like for uniquely identifying the subject in association with the medical information in the storage circuit.

  Next, the flow of processing in the medical system according to the second embodiment will be described. FIG. 10 is a sequence diagram illustrating a flow of processing in the medical system according to the second embodiment. FIG. 10 shows the flow of processing in a medical system including the medical device 400.

  As shown in FIG. 10, in the medical system, when the press of the communication start button with the mobile terminal 300 is accepted (step S301), the information terminal 200 cuts off the communication connection with the medical device and performs virtual access. A point is created and the authentication information is encoded and displayed (step S302). The portable terminal 300 acquires the authentication information by reading the encoded authentication information, and transmits the acquired authentication information to the information terminal 200 (step S303).

  When receiving the authentication information from the portable terminal 300, the information terminal 200 executes the authentication process by comparing the received authentication information with the encoded authentication information (step S304). When the authentication information matches in this authentication process, communication connection between the information terminal 200 and the portable terminal 300 is started in the medical system.

  When the communication connection is started, the information terminal 200 encodes and displays the upload screen address (step S305). The mobile terminal 300 acquires the address of the upload screen by reading the encoded address, and transmits a browsing request for the acquired address to the information terminal 200. When receiving the browsing request from the mobile terminal 300, the information terminal 200 transmits an upload screen corresponding to the request to the mobile terminal 300.

  When receiving the upload screen from the information terminal 200, the portable terminal 300 accepts an operation from the subject and transmits data such as image data and a medical report to the information terminal 200 (step S306). The information terminal 200 stores all received data (medical information) (step S307). When the information terminal 200 accepts pressing of a communication end button for ending communication with the mobile terminal 300 (step S308), the information terminal 200 disconnects the connection with the mobile terminal 300 and executes a virus check ( Step S309).

  After the virus check, when the medical apparatus 400 accepts pressing of the communication start button (step S310), a virtual access point is created, a communication connection with the information terminal 200 is established, and authentication information is displayed ( Step S311). Further, the medical apparatus 400 transmits an authentication information input request to the information terminal 200.

  Upon receiving the authentication information input request, the information terminal 200 receives the authentication information displayed on the medical device 400 and transmits the authentication information to the medical device 400 (step S312). When receiving the authentication information from the information terminal 200, the medical device 400 executes the authentication process by comparing the received authentication information with the displayed authentication information (step S313). When the authentication information matches in this authentication process, the medical system starts communication connection between the information terminal 200 and the medical device 400.

  Thereafter, in the medical device 400, the data of the subject is opened (step S314), and a transfer request for medical information is transmitted. When receiving the transfer request from the medical device 400, the information terminal 200 transmits data such as image data and a medical report to the medical device 400 (step S315). The medical device 400 stores all the received data in association with the corresponding subject data (step S316).

  As described above, in the second embodiment, the information terminal 200 stores the medical information transferred from the mobile terminal 300 in the storage circuit 22 and transfers the stored medical information to the medical device 400. Therefore, in the medical system according to the second embodiment, it is possible to securely and easily transfer medical information such as image data and medical reports stored in the portable terminal of the subject to the medical device 400 in the hospital.
