Description

  The present invention relates to a modality communication analysis system, a modality communication analysis program, and a modality communication analysis method for executing protocol analysis of communication data in modality communication in a medical field.

  Conventionally, monitoring devices (modalities) that acquire biological images such as CT (Computer Tomography) devices and MRI (Magnetic Resonance Imaging) devices that are used in medical settings store or manage test images and effectively transmit test images. In addition, various information is managed by being connected to an image management system such as PACS (Picture Archiving and Communications Systems) for use. In the processing of image information in PACS, information processing is performed in accordance with a standard such as DICOM (Digital Imaging and Communication in Medicine) which is a standard for communication of digital image information acquired by a modality.

  Furthermore, each modality and image management system is connected to a hospital management system that manages various information in the hospital via a network, and the image information acquired by the modality is a common standard for linking with the hospital management system. Information is also processed according to (Integrating Healthcare Enterprise).

  In the management of modalities using such a network, a communication log by an original method is recorded in an image management system such as PACS for each modality. The status of the modality communication is grasped by the local serviceman confirming the communication log at a medical institution or the like where the modality is installed.

  Furthermore, when a communication error such as a DICOM communication connection error of a modality or an abnormal display of a DICOM image in the image management system occurs, a communication log is analyzed by a local serviceman's investigation, and investigation data is acquired. Furthermore, the content of the communication error is grasped based on the survey data.

  If it is difficult for a local service person to handle a communication error, the manufacturer's person in charge, such as a support person or modality development person, is asked to investigate the communication error, and the person in charge of the manufacturer visits a medical institution. The modality is investigated. Alternatively, the survey data is acquired and the communication error is analyzed on the basis of the survey data by the manufacturer.

  Such a conventional error analysis method for modality communication is carried out as a human work by a person in charge such as a local service person, so there is no technical literature.

  In the conventional method of grasping the communication status of the modality and the analysis method of the communication error, the display format of the communication log and the operation method of each modality at the time of error analysis are different for each type of modality. Further, when the manufacturer of a specific modality is different from the manufacturer of the communication destination of the modality, it is difficult to grasp the communication information of the communication destination. In addition, not all communication data can be acquired from the communication log, and the analysis procedure for communication errors of local service personnel is not standardized, resulting in a problem that the investigation time for error analysis becomes long.

  In addition, when it is difficult for a local service person to analyze a communication error, the investigation data acquired by the local service person is transferred to the manufacturer side and the communication error is analyzed. There is a problem that there are variations depending on the local service personnel. For this reason, it is desirable to make it possible for the person in charge of the manufacturer to easily grasp the error situation and execute error analysis by unifying the survey data sent from each local service person to the manufacturer.

  Furthermore, if it is difficult to analyze a communication error even if the survey data is transferred by a local service person, a person in charge of the manufacturer, such as a support person or a person in charge of modality development, must go to the place where the modality is installed. For this reason, it is desired to develop a system that can more easily carry out communication error analysis by a local service person.

  The present invention has been made to cope with such a conventional situation, and in modality communication, even if the type and version of the modality are different, the communication status is grasped and error analysis is performed by a more unified common procedure.

  Next, the operation of the modality communication analysis system 1 will be described.

  FIG. 2 is a flowchart showing a flow when the communication data on the internal network 3 is analyzed by the modality communication analysis system 1 shown in FIG. 1, and the reference numerals with numerals in the figure indicate each step of the flowchart.

  First, in step S1, for example, image data is collected by a modality 5 such as a CT apparatus or MRI apparatus, and transferred to the image management system 6 or in-hospital management system 7 via the internal network 3 as communication data of a standard such as DICOM or IHE. The

  On the other hand, in step S2, the capture time is designated from the capture time designation means 25 or the input means 27 and is given to the communication data capture means 8. The communication data capture means 8 is sent from the repeater HUB 4a to each modality 5, image management system 6 or A packet of communication data transmitted and received between the hospital management systems 7 via the internal network 3 is captured. Further, the communication data capturing means 8 gives a packet of communication data captured as necessary to the monitor 26 for dump display.

  FIG. 3 is a conceptual diagram showing an example of the structure of communication data captured by the modality communication analysis system 1 shown in FIG.

  As shown in FIG. 3, the communication data 40 includes a plurality of packets 41, and each packet 41 includes a MAC address 42, an IP address 43, a TCP header 44, and a DATA 45.

  Then, the communication data capturing means 8 writes each packet 41 of the captured communication data 40 into the captured data database 9, and the communication data 40 is accumulated in the captured data database 9 in time series.

  Next, in step S3, the protocol analysis means 10 reads the communication data from the captured data database 9 and analyzes the protocol to determine whether the communication data conforms to a specified protocol such as DICOM or IHE, thereby specifying the specified standard according to the specified protocol. Extract communication data.

  Further, the protocol analysis unit 10 writes the extracted designated standard communication data into the analysis result database 13, and the designated standard communication data is accumulated in the analysis result database 13 in time series.

  Next, in step S4, the analysis result dump display means 11 reads the designated standard communication data from the analysis result database 13 and gives it to the monitor 26 for display. For example, the analysis result dump display means 11 displays the designated standard communication data on the monitor 26 in time series for each PDU. In addition, the analysis result dump display means 11 adds header information to the designated standard communication data in units of PDUs as necessary.

  Further, the error analysis means 12 reads the designated standard communication data from the analysis result database 13 and gives the tag (Tag) information included in the designated standard communication data to the monitor 26 for display. If there is an error, the error content is given to the monitor 26 to display the error. Further, when there is an error in the tag information, the error analysis unit 12 gives a request for transmitting the corresponding designated standard communication data to the client 31 on the manufacturer side 30 to the survey data transmission unit 24.

  For this reason, it is possible to more uniformly and easily execute the communication status investigation and error analysis of the modality communication in a short time by a local service person at the site 2 such as a medical institution where each modality 5 is installed.

  FIG. 4 is a diagram showing an example of designated standard communication data created by the modality communication analysis system 1 shown in FIG. 1 and dump-displayed together with header information and Tag information.

  As shown in FIG. 4, the specified standard communication data 50 is displayed on the monitor 26 by the time-series tag information 52 with the header information 51 added to each PDU by the analysis result dump display means 11. Each tag information 52 is displayed with an attribute, a name, classification information, and a data length created by the analysis result dump display means 11 together with the tag and the contents of the tag as necessary. Further, when there is an error such as violation of DICOM rules in the tag information 52, an error display 53 is added.

  In FIG. 4, for example, the content (Value) of the tag (Tag) (0008, 0005) is “ISO_IR 100”, the attribute (Grp) is [ID], the name (Attribute Name) is “Specific Character Set”, the classification It can be confirmed that the information (VR) is CS and the data length (Length) is 10.

  Further, for example, an error display “2” is displayed on the tag (0008, 1150), and it can be confirmed that an error exists. For this reason, the local service person can determine the presence or absence of an error earlier.

  Next, in step S5, the designated standard image assembling means 14 reads the designated standard communication data from the analysis result database 13 and generates designated standard image data such as DICOM image data in the designated standard communication data. If assembly data is included, the PDU corresponding to the specified standard image assembly data is extracted to assemble the specified standard image data.

  Furthermore, the designated standard image assembling means 14 writes the assembled designated standard image data into the designated standard image information database 15, and the designated standard image information database 15 stores designated standard image data such as DICOM image data.

  The designated standard image display means 16 reads designated standard image data such as DICOM image data stored in the designated standard image information database 15, converts it into a displayable format, and provides it to the monitor 26, thereby providing the designated standard image. Display. For this reason, the local service person can more easily execute modality communication investigation and error analysis by confirming the designated standard image such as the DICOM image.

  Further, the image format conversion means 17 designates a designated standard image stored in the designated standard image information database 15 when it is necessary to display a designated standard image such as a DICOM image in a designated image format such as JPEG or BMP. The data is read and converted into a designated image format to generate designated format image data. Then, the image format conversion means 17 gives the designated format image data to the monitor 26 for display and writes it in the designated format image information database 18.

  Therefore, it is possible to display a designated standard image such as a DICOM image in a designated image format such as JPEG or BMP on the monitor 26 of the general-purpose computer without using an image viewer or browser of the designated standard image.

  On the other hand, in step S6, the protocol-by-protocol statistics acquisition means 19 reads the time-series communication data from the captured data database 9 and obtains the statistics of the number of packets in a certain time, for example, 1 to 2 seconds for each protocol. Get statistics by protocol. Then, the protocol-specific statistics acquisition unit 19 writes the obtained protocol-specific statistics in the protocol-specific statistical database 20.

  Modality-specific statistics acquisition means 21 reads time-series designated standard communication data from analysis result database 13 and obtains the statistics of the number of packets for a certain time for each modality 5 to obtain each time-series IP address or MAC address. Get statistics by modality. The modality-specific statistics acquisition unit 21 writes the obtained modality-specific statistics in the modality-specific statistics database 22.

  Therefore, the protocol-specific statistics database 20 and the modality-specific statistics database 22 store protocol-specific statistics and modality-specific statistics, respectively.

  Then, the statistical data display means 23 reads the protocol-specific statistics and modality-specific statistics from the protocol-specific statistical database 20 and the modality-specific statistical database 22 and gives them to the monitor 26 for graph display. At the same time, the statistical data display means 23 reads the statistics for each protocol and the statistics for each modality from the statistics database 20 for each protocol and the statistics database 22 for each modality, and gives them to the monitor 26, whereby the entire internal network 3, for each IP address and for each MAC address. List the number of packets for each protocol.

  At this time, the statistical data display means 23 identifies the modality 5 having a large number of packets to be transmitted / received as necessary, for example, the modality 5 in which the number of packets exceeds a certain number or the modalities 5 in a certain order in descending order of the number of packets. It is displayed on the monitor 26.

  For this reason, the local service person can grasp the modality 5 and other factors that place a large communication load on the internal network 3 from the statistics by protocol and the statistics by modality. Furthermore, by setting the time for taking statistics as short as 1 to 2 seconds, the local service person can grasp the temporal transition of statistics by protocol and statistics by modality in real time.

  Next, in step S7, the survey data transmission means 24, based on the data transmission command received from the capture time designation means 25 or the input means 27, capture data database 9, analysis result database 13, designated standard image information database 15, designation. Specify from the survey data such as communication data, specified standard communication data, specified standard image data, specified format image data, protocol-specific statistics, and modality-specific statistics from the standard image information database 15, protocol-specific statistical database 20, and modality-specific statistical database 22. The survey data thus read is read and transmitted to the client 31 on the manufacturer side 30 via the Internet 29 by transmission means such as e-mail or FTP.

  Further, when receiving the specified standard communication data transmission request from the error analyzing unit 12, the investigation data transmitting unit 24 reads the specified standard communication data specified from the analysis result database 13 and transmits it via the Internet 29 to e-mail. It is transmitted to the client 31 on the maker side 30 by transmission means such as FTP.

  For this reason, the communication data, the specified standard communication data, the specified standard image data, the specified format image data can be obtained by the client 31 on the manufacturer side 30 without the person in charge on the manufacturer side such as the support person in charge or the development person in charge of the modality 5 going to the site 2. Based on the survey data such as statistics by protocol and statistics by modality, survey data such as image data can be obtained and confirmed in the same manner as on-site 2.

  Further, by the recording means 28, communication data, specified standard communication data from the captured data database 9, analysis result database 13, designated standard image information database 15, designated standard image information database 15, protocol-specific statistical database 20, and modality-specific statistical database 22. Necessary survey data among survey data such as designated standard image data, designated format image data, statistics by protocol, and statistics by modality is recorded on a recording medium such as an FD.

  Therefore, even if the modality communication analysis system 1 at the site 2 and the client 31 at the manufacturer side 30 are not connected via the Internet 29, the person in charge on the manufacturer side does not go to the site 2 via the recording medium. It is possible to confirm by obtaining survey data.

  According to the modality communication analysis system 1 as described above, in the modality communication using the internal network 3 in the medical institution, even if the type and version of the modality 5 are different, the communication status is grasped by a more unified common procedure. And error analysis.

  That is, according to the modality communication analysis system 1, the communication data is captured from the repeater HUB 4a and the protocol analysis is executed. Therefore, if the modality communication conforms to a protocol such as DICOM or IHE, the modality 5 type and version are changed. Regardless, communication status can be ascertained and error analysis can be performed with standardized descriptions by common procedures and device operations. For this reason, even when communicating with the modality 5 of another manufacturer, it is possible to grasp the communication status and perform error analysis.

  As a result, even when communicating with the modality 5 of another manufacturer, it is possible not only to shorten the investigation time of the communication status of the modality 5 that the manufacturer 30 is in charge of, but also to the variation in the investigation method and procedure for each local service person It is possible to absorb communication, to make it more unified, and to grasp the communication status and analyze errors in a short time.

  In addition, according to the modality communication analysis system 1, since the error analysis result obtained by capturing the communication data and the investigation data such as the communication status are displayed on the screen uniformly and can be referred to by the local service person, Investigation becomes easy. At this time, since the specified standard image such as the DICOM image can be displayed together with the communication data, the communication status and the content of the error can be confirmed more easily.

  Furthermore, even if it is difficult for a local service person to conduct a survey, the survey data can be recorded on a recording medium such as an FD together with designated standard image data, or by an information transmission means such as an E-mail using the Internet 29. Since the data can be transmitted to the side 30, the survey data can be easily reported, and the survey time can be shortened. As a result, it is possible to reduce the number of business trips to the local site for the person in charge of the manufacturer, such as a person in charge of support or a person in charge of modality development.

  In addition, since the person in charge on the manufacturer side can refer to the designated standard image data together with the error analysis result, it is easy to determine whether the designated standard image data is normal by comparing the communication error content with the designated standard image data, It can be investigated in a shorter time.

  Furthermore, since the modality communication analysis system 1 can specify the capture time of communication data, if the setting is made so that the required survey data is transmitted to the manufacturer side 30 at the required time, there is no local service person. However, the person in charge on the manufacturer side can remotely monitor the modality communication.

  Further, since the modality communication analysis system 1 is configured to record the obtained various survey data, an image that could not be transmitted / received on the internal network 3 due to an error can be transmitted / received again. Furthermore, the modality communication analysis system 1 can be used as a temporary backup device. For this reason, even if the image management system 6 or the hospital management system 7 is out of order, the communication data transmitted from each modality 5 can be recorded and the image data such as DICOM image data can be displayed.

  In particular, the modality communication analysis system 1 can convert specified standard image data such as a DICOM image into an image format such as JPEG and save it. Therefore, image data of a required image format can be saved regardless of a browser or viewer dedicated to the specified standard image. If there is a displayable terminal, an image can be displayed. Furthermore, by converting the designated standard image data into an image format such as JPEG, the data size can be reduced, and transmission via the Internet 29 is facilitated.

  Further, the modality communication analysis system 1 is configured to take statistics of communication data captured from the internal network 3 for each protocol or modality 5, so that the load on the internal network 3 can be grasped. The configuration of the internal network 3 and the communication data backup schedule in each modality 5 can be reviewed.

  The modality communication analysis system 1 may be configured to capture communication data not from the repeater HUB 4a but from the switching HUB 4b. Communication data may be captured not only from the internal network 3 but also from an external network such as the Internet 29.

  In the modality communication analysis system 1, some of the functions of the modality communication analysis system 1 may be omitted, or may be distributed between the site 2 and the manufacturer side 30. For example, at the site 2, the protocol analysis may be executed on the manufacturer side 30 only by capturing and recording the communication data.
