  Referring to FIG.

  Via the VPN connection established by the VPN router 303 provided in the moving vehicle 100 and the VPN router 400 provided in the facility 200, it is connected to the VPN router 400 and provided in the facility 200. 1 is a diagram illustrating a configuration of a medical image transfer system that transfers a medical image 301 captured by a modality device 300 in a moving vehicle 100 to an information processing apparatus 401. FIG.

  The mobile vehicle 100 is, for example, a bus that is dispatched from a health examination facility to a health examination venue at the time of a health examination, and an X-ray digital inspection device that captures X-ray images of the chest and abdomen is installed in the office. . The X-ray digital inspection apparatus is a suitable example of the modality apparatus 300 in the present invention.

A medical image (DICOM image) photographed by the modality device 300 is connected to the information processing device 302 via a wired network cable. Even if wireless communication is performed at a short distance such as Bluetooth (registered trademark). Good.
The information processing apparatus 302 and the VPN router 303 have a LAN built in a moving vehicle.

  The VPN router 303 is for constructing a VPN environment with the VPN router 400, and is also called an Internet VPN. It is possible to perform data mutual communication between the two while suppressing wiretapping of data communicated between the two.

  The facility 200 is, for example, a medical checkup medical center that manages the results of a medical checkup. However, the facility 200 is not limited to a medical facility such as a hospital, and specializes in medical images as long as it can be installed in a fixed state. It may be a data center or the like that is a facility to be managed.

The medical image management server (information processing device) 403 is, for example, a PACS (medical image management system), and stores, browses, and manages image data received from an image photographing device (modality) such as CT or MRI.
Dongle device 304 functions as a communication means for data communication using radio waves transmitted from a communication carrier telephone network. The dongle device 304 is connected to the VPN router 303 via USB, can receive LTE (4G) and 3G radio waves transmitted from a communication carrier, and performs data communication using LTE (4G) and 3G radio waves. It can be performed.

In this embodiment, the dongle device 304 is USB-connected to the VPN router 303 and each is a separate device. However, as a modification, the dongle device 304 may be a VPN router 303 with a built-in dongle device 304.
FIG. 2 will be described.
<Operation by Modality 300>

By executing a program that can be read and executed by the CPU of the modality 300, an operation instruction for each step is given, and each step (process) shown in the figure is executed.
In S101, the modality 300 captures a medical image (DICOM image file) of the patient.

In S <b> 102, the modality 300 transmits the captured DICOM image file 301 to the information processing apparatus 302 as an SCP (Service Class Provider).
<Operation by Information Processing Device 302>

It is assumed that the CPU of the information processing apparatus 302 executes a program that can be read and executed, thereby instructing operation of each step and executing each process (process) shown in the figure.
In S103, the information processing apparatus 302 receives the transmitted DICOM image file as an SCU (Service Class User).
In step S104, the information processing apparatus 302 stores the received DICOM image file in a predetermined folder.

In step S105, the information processing apparatus 302 starts compression processing of the DICOM image file stored in the folder. This is to reduce the size of the DICOM image file captured by the modality 300 in the moving vehicle, and compresses the DICOM image file by a predetermined compression process (compression unit). Since the predetermined compression processing is decompressed at the facility side, it may be any reversible compression, and for example, a compression of the DICOM image file size in the ZIP format or the like is preferable. The size of the DICOM image file before compression is on average 16 to 20 MB per file.
In S106, the information processing apparatus 302 determines whether or not the compression process has been completed. If it is determined that the compression process has ended (YES), the process proceeds to S107.

  In step S107, the information processing apparatus 302 stores the compressed DICOM image file (compressed image file) in a storage unit (for example, a hard disk drive) of the information processing apparatus 302 (storing unit).

Furthermore, when it is first determined in S116 that the transfer rate is not good, the transfer is temporarily stopped. Therefore, after it is determined in S116 that the transfer rate is not good, the transfer rate is good again in S116. Until the determination, the compressed image file captured by the modality 300 in the moving vehicle may be temporarily stored in the storage unit. After it is determined again in S116 that the transfer speed is good, the temporarily stored compressed image file may be transferred.
In S108, the information processing apparatus 302 receives the latest radio wave strength acquired by the dongle apparatus 304 from the VPN router 303 (reception unit).

  In S109, the information processing apparatus 302 determines whether or not the transfer status of the compressed image file captured by the modality 300 to the information processing apparatus 401 is good based on the strength and weakness received in S108 (first determination unit). ). Thus, control is performed so that the transfer mode to the information processing apparatus 401 in S110 is switched in accordance with the transfer status determined in S109 (control means).

If it is determined in S109 that the transfer status is good (YES), the process proceeds to S115, and if it is determined in S116 that the transfer status is not good (No), the process proceeds to S111.
In S115, the information processing apparatus 302 measures the data communication speed using the radio wave that the VPN router 303 performs data communication (measurement means).

  Furthermore, based on the communication speed measured here, communication speed information that can identify whether or not the transfer speed of the compressed image file captured by the modality 300 to the information processing apparatus 401 is good is displayed on the screen of the information processing apparatus 302 ( (Not shown) display (display means).

  In S116, the information processing apparatus 302 determines whether the transfer speed of the compressed image file captured by the modality 300 to the information processing apparatus 401 is good based on the communication speed measured in S115 (second determination unit). ). If it is determined in S116 that the communication speed is good (YES), the process proceeds to S110. If it is determined in S116 that the communication speed is not good (No), the process proceeds to S111.

  In S110, the information processing apparatus 302 uses the radio waves that the VPN router 303 performs data communication to store the compressed image file photographed by the modality 300 in the moving vehicle in the information processing apparatus 401 using FTP (File Transfer Protocol). Transfer to a file path of a folder created in advance (transfer means).

  In S111, the information processing apparatus 302 determines that the transfer speed is not good in S116. Therefore, until the transfer speed is determined to be good again in S116, the information captured by the modality 300 in the moving vehicle is compressed. The transfer of the image file is paused (pause means).

In step S113, the information processing apparatus 302 searches for a folder in which the compressed image file is stored, and determines whether there is another compressed image that has not been transferred. If it is determined that there is another compressed image file (YES), the process returns to S107, and the processes after S108 are repeated. If it is determined that there is no other compressed image file (NO), the process waits until a new DICOM image of the patient is created in S101 (S114).
<Operation by VPN router 303>

It is assumed that the CPU of the VPN router 303 executes a program that can be read and executed, thereby instructing the operation of each step and executing each process (process) shown in the figure.
In S201, the dongle device 304 receives a radio wave (LTE or 3G) transmitted from the communication carrier telephone network.

  In S202, the VPN router 303 acquires the radio wave level (LTE or 3G) of the radio wave (LTE or 3G) received by the dongle device 304 as needed (acquisition means). The acquired radio wave level (strong / weak state) is transmitted to the information processing apparatus 302 as needed via a LAN cable. In this way, in S108, the information processing apparatus 302 monitors the latest radio wave level (strength situation).

In S203, the VPN router 303 communicates dummy test data for measuring the communication speed with the VPN router 400 according to an instruction from the information processing apparatus 302 or a periodic program. After the measurement, the communication result of the dummy test data is transmitted to the information processing apparatus 302.
In step S112, the VPN router 303 routes the compressed image file instructed by the information processing apparatus 302 to FTP transfer in step S110 to the VPN router 400.
FIG. 3 will be described.
<Operation by VPN router 400>

It is assumed that the CPU of the VPN router 400 executes a program that can be read and executed, thereby instructing operation of each step and executing each process (process) shown in the figure.
In S301, the VPN router 400 is connected to a LAN in a facility capable of Internet communication.
In S <b> 302, the VPN router 400 routes the compressed image file instructed by the information processing apparatus 302 to FTP transfer in S <b> 110 to the information processing apparatus 401.
<Operation by Information Processing Device 401>

By executing a program that can be read and executed by the CPU of the information processing apparatus 401, an operation instruction for each step is given, and each process (process) shown in the figure is executed.
In step S <b> 303, the information processing apparatus 401 receives the compressed image file transferred by FTP from the information processing apparatus 302.
In step S304, the information processing apparatus 401 stores the received compressed image file in a folder in the information processing apparatus 401 predetermined in step S110.

In step S <b> 305, the information processing apparatus 401 starts decompression processing of the compressed image file stored in the folder. This is to restore the original DICOM image file size captured by the modality in the moving vehicle, and decompress the compressed image file by a predetermined decompression process (decompression means).
In step S306, the information processing apparatus 401 determines whether or not the decompression process has ended. If it is determined that the processing has ended (YES), the processing proceeds to step S307.
In step S <b> 307, the information processing apparatus 401 saves the decompressed DICOM image file in a storage unit (for example, a hard disk drive) of the information processing apparatus 401.

  In step S <b> 308, the information processing apparatus 401 transmits the stored DICOM image file 402 to the server apparatus 403 as an SCP (Service Class Provider).

In step S <b> 310, the information processing apparatus 401 searches for a folder in which the DICOM image file is stored, and determines whether there is another DICOM image file that has not yet been transferred to the server apparatus 402. If it is determined that there is another DICOM image file (YES), the process returns to S307, and the processes after S308 are repeated. If it is determined that there is no other DICOM image file (NO), the process waits until a new compressed image of the patient is received in S303 (S311).
<Operation by Server Device 403>

  By executing a program that can be read and executed by the CPU of the server apparatus 403, an operation instruction for each step is given, and each process (process) shown in the figure is executed.

  In step S309, the server apparatus 403 receives the transmitted DICOM image file as an SCU (Service Class User). The server device 403 manages the received DICOM image file as a medical image for each patient.

  FIG. 4 is a block diagram illustrating a hardware configuration of the information processing apparatus applicable to the information processing apparatus 302, the information processing apparatus 401, and the medical image management server 403 illustrated in FIG.

  In FIG. 4, reference numeral 1 denotes a CPU, which comprehensively controls each device and controller connected to the system bus 4. Further, the ROM 2 or the external memory 11 is necessary to realize a BIOS (Basic Input / Output System) or an operating system program (hereinafter referred to as an OS), which is a control program of the CPU 1, or a function executed by each server or each PC. Various programs to be described later are stored.

  Reference numeral 3 denotes a RAM that functions as a main memory, work area, and the like of the CPU 1. The CPU 1 implements various operations by loading a program or the like necessary for execution of processing from the ROM 2 or the external memory 11 into the RAM 3 and executing the loaded program.

  An input controller 5 controls input from a keyboard (KB) 9 or a pointing device such as a mouse (not shown). A video controller 6 controls display on a display such as a CRT display (CRT) 10. In FIG. 2, although described as CRT10, the display device is not limited to the CRT, but may be another display device such as a liquid crystal display. These are used by the administrator as needed.

  Reference numeral 7 denotes a memory controller, which is installed in an external storage device (hard disk (HD)), flexible disk (FD), or PCMCIA card slot for storing a boot program, various applications, font data, user files, editing files, various data, and the like. Controls access to an external memory 11 such as a CompactFlash (registered trademark) memory connected via an adapter.

  A communication I / F controller 8 connects and communicates with an external device via a network LAN, and executes communication control processing in the network. For example, communication using TCP / IP is possible.

  The CPU 1 enables display on the CRT 10 by executing, for example, outline font development (rasterization) processing on a display information area in the RAM 3. Further, the CPU 1 enables a user instruction with a mouse cursor (not shown) on the CRT 10.

  FIG. 5 shows a setting file stored in the information processing apparatus 302, and the transfer status condition 5001 in the setting file is used as the threshold value of the transfer status determined in S109. Note that the transfer status condition 5001 can be freely changed by the user rewriting the transfer status condition 5001 in the setting file. For example, when the strength of the received radio wave is low and the transfer status condition 5001 is medium, it is determined in S109 that the transfer status is not good (NO).

Further, the communication speed condition 5002 in the setting file is used as the threshold value of the transfer status determined in S116. Note that the communication speed condition 5002 can be freely changed by the user rewriting the communication speed condition 5002 in the setting file. For example, when the measured radio wave communication speed is 2 Mbps (bits per second) and the communication speed condition 5002 is 100 kbps (bits per second), it is determined that the communication speed is good (YES) in S116. For example, when transferring a DICOM image file having a capacity of 10M in a state of 100 kbps, it takes 100 seconds per file to complete the transfer. Since many patients continuously perform X-ray imaging in the medical examination, the communication speed condition 5002 may be set to an imaging interval for each patient. For example, when the X-ray imaging interval (frequency) for each patient is set as 100 seconds in advance in the setting file of FIG. The communication speed condition 5002 may be automatically calculated, automatically set to 100 kbps (bits per second) or more, and registered, so that the communication speed condition 5002 optimum for the imaging interval for each patient may be automatically calculated.
FIG. 6 is a transfer management table for DICOM images managed by the information processing apparatus 302, and is a table for managing the current transfer status for each captured DICOM image.
Reference numeral 6001 denotes a management ID assigned to each photographed patient.
Reference numeral 6002 denotes a management ID assigned to each captured DICOM image.
Reference numeral 6003 denotes a folder path (save location) where the captured DICOM image is saved, and the path is automatically saved in the path designated here.

  Reference numeral 6004 denotes the status of the latest transfer status, which is updated during the process of S105, compressed during the process of S110, transferred during the process of S110, and updated at any time if the transfer has already been completed.

  Various programs to be described later for realizing the present invention are recorded in the external memory 11 and are executed by the CPU 1 by being loaded into the RAM 3 as necessary. Furthermore, definition files and various information tables used when executing the program are also stored in the external memory 11, and detailed descriptions thereof will be described later.
