Description

  The present invention relates to provision of data indicating image display quality.

  In recent years when filmlessness has progressed, the number of cases where images are handled as electronic data has increased. For example, a hard copy such as a film has been conventionally used for diagnosis of a medical image generated by a CR (Computed Radiography) imaging device, a CT (Computed Tomography) imaging device, or the like, but in recent years, a computer display device ( Diagnosis by browsing images displayed on the monitor is also possible.

  For example, there is a technique (system) for improving the efficiency of image diagnosis work when a storage form in which electronic medical records are stored in a medical facility and medical image data is stored in a data center is employed (for example, Patent Document 1). reference). That is, an image output means for outputting medical image data received from a server via the Internet by a client terminal provided in a medical facility, and an electronic medical record output means for outputting medical chart data stored in the electronic medical record storage means And the control means provided in the client terminal uses the related information associating the medical chart data with the medical image data, and outputs the medical chart data and the medical image data related to each other as an electronic medical chart output means. And a function of a collaborative output means for outputting in cooperation with the image output means.

  On the other hand, in the diagnosis of medical images using such a monitor, it is possible to reduce the time, cost, and storage location for transportation, and prevent loss of images as compared with the case of using a film. While there are significant advantages, there are problems with image quality.

  For example, in a large-scale medical institution such as a general hospital, a large number of devices for generating medical images are installed, and a specialist engineer such as a radiographer is in charge of operation of each device. The doctor obtains image data that has been captured and confirmed by a radiologist or the like, for example, via a network and interprets the image data. In this case, for example, if a doctor interprets a diagnostic image that has been quality-checked by a radiologist using a dedicated high-resolution monitor, the doctor may interpret the diagnostic image on a different monitor, and the appearance may be different from that at the time of quality confirmation. In other words, due to differences in resolution and brightness due to different monitors, doctors cannot accurately interpret images, which may lead to a diagnosis error.

With regard to this, for example, there is a technique for displaying the same image in the same manner on each image display device connected to the network without depending on individual hardware characteristics (see, for example, Patent Document 2). That is, an image management system for managing an image file displayed and output on a network-connected image display device, the image file recording means for recording the image file, and the gradation for each type of display output in the image display device A gradation table storage unit that stores a plurality of gradation tables that define the characteristics, and a transmission unit that transmits an image file together with a gradation table corresponding to the type of display output of the image display apparatus serving as a transfer destination.

  However, the image is viewed by the technician who is in charge of capturing and checking the image and the doctor who diagnoses the image, such as the difference in pixel density before and after the compression processing is performed when the image data is stored and transferred. There are other factors in the difference between the two. Moreover, even if it looks the same, when both the engineer and the doctor see an image with low luminance or low resolution, an appropriate diagnosis cannot be expected. For example, it is conceivable that the dedicated high-resolution monitor deteriorates and the brightness decreases, and a plurality of monitors having different resolutions cannot be unified to a high resolution by software processing.

  In other words, there is a limit to image adjustment by software as in the prior art described above. Also, especially when the object to be handled is a medical image, there should be no diagnostic error, so in some cases the doctor may go to the engineer who checked the image and check the image in exactly the same environment. Although it may be necessary, data that can serve as a basis for such determination is not shown in the prior art.

  Therefore, an object of the present invention is to provide a novel technique for enabling appropriate image diagnosis.

  The image display quality data providing device according to the present invention displays the image display quality when the first display device of the user terminal displays an image based on the first image data for the first display device. An image display quality data providing device for providing data, wherein first data relating to display quality when first image data for a first display device is displayed on the first display device is acquired, First data acquisition means for storing in the data storage unit, display quality when the second image data for the second display device corresponding to the first image data is displayed on the second display device, and in advance A difference between the second data stored in the second data storage unit and the first data stored in the first data storage unit is extracted, and data relating to the difference is stored in the difference data storage unit Difference data extraction means In response to a request from the user terminal, and an image display quality data transmission means for transmitting the image display quality data containing data about different matters stored in different data storage unit to the user terminal.

  Thereby, the user who is a doctor, for example, can know the difference between the quality of the image displayed on the monitor of the terminal being used and the quality of the image confirmed by, for example, the radiologist under different environments. Diagnosis is made after knowing the difference, so diagnosis errors are less likely to occur. For example, it is possible to determine that the image that the user is currently viewing is not of a quality that can withstand diagnosis and review the image in another environment.

  The first data and the second data include at least one of a name that can identify the display device, an image compression ratio, a resolution of the display device, and a luminance of the display device. May be. Based on such parameters, the doctor can make a diagnosis while being aware of the difference in image display quality.

  The second data may include data relating to deterioration of the second display device. Thereby, for example, a user who is a doctor can know whether or not the image display quality of the dedicated monitor used by the radiologist or the like for confirming the image has deteriorated due to deterioration. For example, even if a doctor can refer to an image having the same level of quality as an image confirmed by a radiologist or the like, an accurate diagnosis cannot be made unless the quality of the image confirmed by the radiologist or the like is at an appropriate level in the first place. It becomes possible to judge.

  The image display quality data providing method according to the present invention is executed by a computer when an image based on the first image data for the first display device is displayed on the first display device of the user terminal. Image display quality data providing method for obtaining first data relating to display quality when displaying first image data for the first display device on the first display device, and storing the first data The second image data for the second display device corresponding to the first image data and the display quality when the second image data is displayed on the second display device, and stored in the second data storage unit in advance. Extracting the difference between the stored second data and the first data stored in the first data storage unit, storing the data related to the difference in the difference data storage unit, and from the user terminal Key points of Depending on, and transmitting the image display quality data containing data about the stored difference matters difference data storage unit to the user terminal.

  Further, the modification of the image display quality data providing apparatus according to the present invention can be applied to the image display quality data providing method according to the present invention.

  It is possible to generate a program for carrying out the method according to the present invention, and the program is a storage medium such as a flexible disk, a CD-ROM, a magneto-optical disk, a semiconductor memory, a hard disk or the like. Stored in the device. Moreover, it may be distributed as a digital signal via a network. Note that data being processed is temporarily stored in the memory of the computer.

  According to the present invention, the user can browse images after knowing the difference in image display quality under different environments, and can make an appropriate determination.

  A system configuration diagram according to an embodiment of the present invention is shown in FIG. For example, a network 1 that is a hospital network of a medical institution includes one or a plurality of electronic medical record system terminals 3 and image system terminals 7 that are terminal devices such as workstations and personal computers, and one or a plurality of electronic medical record systems. The server 5, one or a plurality of image system servers 9, and one or a plurality of imaging apparatuses 11 that are imaging apparatuses such as CR and CT are directly or indirectly connected.

  The electronic medical record system terminal 3 includes a monitor information acquisition program 33 and an electronic medical record system / client program 35, to which a monitor 31 is connected. The monitor information acquisition program 33 is a program that acquires information on the monitor 31 such as resolution and brightness and stores the information in a predetermined file. As an information acquisition method, it may be automatically detected by a sensor, or input from a user may be accepted. The electronic medical record system client program 35 is a client program for accessing the electronic medical record system server 5 and executing processing using the electronic medical record. The client program is not necessarily a dedicated client program, and may be a web browser, for example. In the present embodiment, the electronic medical record system terminal 3 is mainly used by a doctor.

  The image system terminal 7 includes a monitor information acquisition program 73 and an image system client program 75, and is connected to a monitor 71. The monitor information acquisition program 73 is a program that acquires information on the monitor 71 such as resolution and brightness and stores the information in a predetermined file. The information acquisition method is automatically detected by a sensor, but input from a user may be accepted. For example, information on the monitor 71 is acquired in conjunction with a dedicated sensor device provided in the monitor 71.

  The image system client program 75 is a program for accessing the image system server 9 and executing registration processing of image data generated by the photographing apparatus 11. At the time of image registration, image attribute data such as the shooting date / time and subject data of the image, and information on the monitor 71 used for checking the image are also transmitted. Further, since image data generated by the photographing apparatus 11 generally has a large file size, an image system server program 93 (described later) of the image system server 9 compresses received image data. Note that the image system client program 75 is not necessarily a dedicated client program, and may be a Web browser, for example.

  The monitor 71 is a display device for confirming an image photographed by the photographing device 11 on the spot, and has a relatively high resolution and brightness. In the present embodiment, the image system terminal 7 is mainly used by a person in charge of taking and confirming an image, such as a radiologist.

  The image system server 9 includes an image system server program 93, a monitor information storage program 95, and a monitor information transmission program 97, and an image database (DB) 91 is connected thereto. The image system server program 93 is a program for accepting access from the image system terminal 7 and performing processing related to registration processing of image data in the image DB 91, management of image data, browsing, and the like. The monitor information storage program 95 is a program that stores information related to the monitor 71 of the image system terminal 7 received from the image system terminal 7 in the image DB 91. The monitor information transmission program 97 is a communication interface for transferring information related to the monitor 71 received from the image system terminal 7 to the electronic medical record system server 5. The image DB 91 stores image data, information about the monitor 71, and the like.

  As described above, since the image data generated at the time of photographing by the photographing device 11 has a large file size as it is, the compression processing is generally performed prior to storage or communication. For this reason, the image data stored in the image DB 91 has a smaller file size than the original image data, but may have a lower quality accuracy.

  The electronic medical record system server 5 includes an electronic medical record system server program 53, a monitor information storage program 55, and a monitor information reception program 57, and is connected to an electronic medical record DB 51. The electronic medical record system server program 53 is a program for accepting access from the electronic medical record system terminal 3 and performing processing relating to management and browsing of electronic medical record data. The monitor information storage program 55 is a program that stores information related to the monitor 71 of the image system terminal 7 received from the image system server 9 in the electronic medical record DB 51. The monitor information receiving program 57 is a communication interface for receiving information related to the monitor 71 transmitted by the image system server 9. The electronic medical record DB 51 stores digitized medical record data, information about the monitor 71, and the like.

  2 and 3 show an example of the table configuration of the monitor initial use information table and the image DB monitor information table included in the image DB 91 and stored data. First, FIG. 2 shows an example of the monitor initial use information table. 2 includes a terminal ID column 200, a device name column 202, a purchase date column 204, a manufacturer column 206, a first use date / time column 208, a monitor resolution column 210, and a monitor luminance column 212. And are included. In this monitor initial use information table, a record is registered when the monitor 71 is used for the first time for confirming an image photographed by the photographing apparatus 11. The record may be generated based on the data acquired by the monitor information acquisition program 73, or input from the user may be accepted at the time of initial registration.

  FIG. 3 shows an example of the image DB monitor information table. In the example of FIG. 3, an inspection ID column 300, an inspection date / time column 302, a confirmation date / time column 304, a confirmation terminal ID column 306, an apparatus name column 308, an image compression rate column 310, and a monitor resolution column 312. And a monitor luminance column 314 and a luminance difference column 316 are included. When the image system server 9 receives image data from the image system terminal 7, a record of this image DB monitor information table is generated and registered based on the received image attribute data and information on the monitor 71. . The luminance difference column 316 stores the difference between the value of the monitor luminance column 212 and the value of the monitor luminance column 314 in the corresponding record (the terminal ID is the same) in the monitor initial use information table (FIG. 2). The The values in the luminance difference column 316 are calculated and stored by the monitor information storage program 95 of the image system server 9.

  In addition to this, the image DB 91 includes a table for storing image data, but the illustration and description are omitted because of a general table configuration.

  4 and 5 show an example of the table configuration of the document table and the chart DB monitor information table included in the electronic medical record DB 51, and stored data. First, FIG. 4 shows an example of a document table. The example in FIG. 4 includes a document ID column 400, a patient ID column 402,..., A result column 404, and an image ID column 406. This document table stores data relating to the electronic medical record, and the record can be specified by the value in the column 400 of the document ID. When the electronic medical record system server 5 receives information on the monitor 71 from the image system server 9, a record of this document table is generated and registered based on the image attribute data received together. Note that data registration / editing may be performed by a doctor operating the electronic medical record system terminal 3 to access the electronic medical record system server 5, for example.

  FIG. 5 shows an example of a chart DB monitor information table. 5 includes a document ID column 500, an inspection ID column 502, an inspection date column 504, a confirmation date column 506, a confirmation terminal ID column 508, an apparatus name column 510, and an image compression rate column 512. And a monitor resolution column 514, a monitor luminance column 516, and a luminance difference column 518. When the electronic medical record system server 5 receives information on the monitor 71 and image attribute data from the image system server 9, a record of this document table is generated and registered. The table structure is such that a document ID column 500 is added to the (duplicate) table similar to the image DB monitor information table shown in FIG. 3 and associated with the document table (FIG. 4).

  Next, processing contents of the system shown in FIG. 1 will be described with reference to FIGS. First, the image system client program 75 of the image system terminal 7 acquires the image data and shooting data generated by the shooting device 11 and temporarily stores them in the storage device (FIG. 6: step S1). Note that the shooting data is image attribute data including the shooting date and time of the image, data on the subject, and the like.

  Then, the image system client program 75 displays an image on the monitor 71 using the acquired image data (step S3). For example, a professional engineer in charge of confirming the image confirms the image displayed on the monitor 71. The image system client program 75 accepts the input of quality check data from a professional engineer using a quality check page (not shown), for example, and temporarily stores it in the storage device (step S5). Note that there may be a case where part of the quality check data is included in the shooting data acquired in step S1, and in such a case, input of the remaining data is prompted.

  FIG. 7 shows an example of quality check data. The example of FIG. 7 includes an examination ID row 700, a patient ID row 702, an examination date / time row 704, a confirmation date / time row 706, an imaging device name row 708, an imaging device purchase date / time row 710, and an imaging device. A maker row 712, a photographing device display luminance row 714, a confirmation terminal ID row 716, a confirmation device name row 718, an image compression rate row 720, and an image ID (file name) row 722 are included. In the present embodiment, values for the confirmation date / time row 706, the confirmation terminal ID row 716, and the confirmation device name row 718 are registered by data input from an expert engineer. A value is registered based on the described photographing data. Further, when the image data is preliminarily compressed by the photographing apparatus 11, the compression rate is registered in the image compression rate row 720. Actually, the quality check data is a list of values in the right column (data column), for example, separated by commas.

  Returning to the description of FIG. 6, the monitor information acquisition program 73 of the image system terminal 7 acquires information on the monitor 71 according to, for example, the operation of a professional engineer and stores it in a predetermined file (FIG. 6: step S7). For example, information on the monitor 71 is acquired in conjunction with a dedicated sensor device provided in the monitor 71. The monitor information includes, for example, resolution and luminance. Note that this step is not necessarily performed at this point, and may be performed periodically, for example.

  Then, the image system client program 75 of the image system terminal 7 transmits image data, quality check data, and monitor information to the image system server 9 in accordance with the operation of the professional engineer (step S9). For example, using a transmission data confirmation page (not shown) or the like, a confirmation operation for data to be transmitted or a file attachment instruction is accepted, and the data is transmitted.

  The image system server program 93 of the image system server 9 receives the image data from the image system terminal 7, compresses it, and stores it. Further, the quality check data and the monitor information are received from the image system terminal 7 and temporarily stored in the storage device (step S11). The image ID (file name) and image data of the quality check data are stored in an image table (not shown) of the image DB 91.

  Then, the monitor information storage program 95 of the image system server 9 searches the monitor initial use information table based on the quality check / data confirmation terminal ID and the confirmation device name, and confirms whether or not the corresponding record exists. It is determined whether the monitor used for image confirmation is a new monitor (step S13).

  When it is determined that the monitor is a new monitor (step S13: Yes route), the monitor information storage program 95 generates a record of the monitor first use information table (FIG. 2) based on the quality check data and the monitor information, The image is stored in the image DB 91 (step S15). For items that are not included in the received data, such as the date of purchase and manufacturer name, page data that prompts input may be transmitted to the image system terminal 7 to allow a specialist to input data. However, data may be extracted from a terminal monitor DB (not shown) or the like. And it transfers to the process of step S19 mentioned later.

  On the other hand, if it is determined that the monitor is not a new monitor (step S13: No route), the monitor information storage program 95 includes the value in the monitor luminance column 212 of the corresponding record in the monitor initial use information table (FIG. 2), The difference with the brightness included in the received monitor information is calculated and temporarily stored in the storage device (step S17). The brightness difference data is data indicating the degree of deterioration of the monitor 71.

  The monitor information storage program 95 generates a record of the image DB monitor information table (FIG. 3) based on the quality check data and the monitor information, and stores it in the image DB 91 (step S19). When this process is performed via step S17, the luminance difference value calculated in step S17 is registered in the luminance difference column 316 (FIG. 3). When this processing is performed via step S15, “0” is registered in the luminance difference column 316 (FIG. 3).

  When the process of step S19 is completed, the monitor information transmission program 97 of the image system server 9 transmits monitor information including quality check data and luminance difference data to the electronic medical record system server 5 (step S21). The monitor information receiving program 57 of the electronic medical record system server 5 receives the monitor information including the quality check data and the luminance difference data from the image system server 9, and temporarily stores it in the storage device (step S23). At this time, the monitor information storage program 55 of the electronic medical record system server 5 performs the document table (FIG. 4) and the medical record DB monitor information table (based on the monitor information including the received quality check data and luminance difference data). 5) is generated and stored in the electronic medical record DB 51. In addition, the quality check data is stored in a predetermined area of the electronic medical record DB 51.

  In this way, information about the image and environment confirmed by the professional engineer is held in the server. Hereinafter, processing for using data stored in the server will be described.

  First, the electronic medical record system client program 35 of the electronic medical record system terminal 3 transmits a request for electronic medical record screen data to the electronic medical record system server 5 in accordance with an operation of a user who is a doctor, for example (FIG. 8: Step S31). It is assumed that login processing has been performed before this.

  The electronic medical record system server program 53 of the electronic medical record system server 5 receives a request for electronic medical record screen data from the electronic medical record system terminal 3 (step S33). Then, the electronic medical record system server program 53 generates electronic medical record screen data based on the data of the document table (FIG. 4) of the electronic medical record DB 51 and transmits it to the electronic medical record system terminal 3 (step S35). The electronic medical record system client program 35 of the electronic medical record system terminal 3 receives the electronic medical record screen data from the electronic medical record system server 5 and displays it on the monitor 31 (step S37).

  Although not shown, the electronic medical chart screen shows a list of medical charts and includes a button for shifting to a detailed display of each chart. For example, there are a “display report” button and a “display result” button, and the button to be displayed corresponding to each chart is determined by the attribute of the chart, that is, the value in the result column 404 of the document table. The In the present embodiment, the chart attribute relating to image shooting is “image”.

  Then, for example, when a “display result” button associated with one of the medical charts is clicked by a user who is a doctor, the electronic medical record system client program 35 of the electronic medical record system terminal 3 issues a test result display instruction. Accept (step S39). Then, the electronic medical record system client program 35 transmits a request for the result display screen data to the electronic medical record system server 5 (step S41). At this time, the document ID of the selected chart is also transmitted.

  The electronic medical record system server program 53 of the electronic medical record system server 5 receives the request for the result display screen data and the document ID from the electronic medical record system terminal 3, and temporarily stores them in the storage device (step S43). Then, the electronic medical record system server program 53 generates result display screen data based on the data of the document table (FIG. 4) of the electronic medical record DB 51 and transmits it to the electronic medical record system terminal 3 (step S45). The electronic medical record system client program 35 of the electronic medical record system terminal 3 receives the result display screen data from the electronic medical record system server 5 and displays it on the monitor 31 (step S47).

  Although not shown, the result display screen includes detailed medical record information, doctor's findings, thumbnail images, and the like. The doctor's findings are registered using another editing screen. When displaying thumbnail images, the image system server program 93 of the image system server 9 generates thumbnail images in advance and stores them in the image DB 91, which is stored in the electronic medical record system server 5. The system server program 53 extracts.

  The result display screen further includes an “image quality accuracy display” button and an “image display” button. For example, a user who is a doctor clicks an “image quality accuracy display” button when he / she wants to know the environment when a professional engineer confirms an image. If you want to see an image in standard size instead of a thumbnail, click the “Display Image” button. Note that an image having a standard size may be displayed by clicking a thumbnail image. In addition, when there are a plurality of images, it is possible to identify which image the processing is for. For example, radio buttons are associated with thumbnail images, and “image quality accuracy display” buttons and “image display” buttons are provided by the number of images.

  Then, the electronic medical record system client program 35 of the electronic medical record system terminal 3 accepts a selection input from the user for the result display screen, and transmits the selection input data to the electronic medical record system server 5 (step S49). The electronic medical record system server program 53 of the electronic medical record system server 5 receives selection input data from the user for the result display screen from the electronic medical record system terminal 3, and temporarily stores it in the storage device (step S51).

  Then, the electronic medical record system server program 53 determines whether the selection input from the user to the result display screen is an image display, that is, whether the “image display” button is clicked (step S53). If it is determined that the image is displayed (step S53: YES route), the process proceeds to the process of FIG.

  On the other hand, when it is determined that the display is not an image display (the display is an image quality accuracy display) (step S53: No route), the electronic medical record system / server program 53 displays the medical record DB monitor information table (see FIG. The image quality accuracy screen data is generated using the data 5) and the quality check data, and transmitted to the electronic medical record system terminal 3 (step S55). The electronic medical record system client program 35 of the electronic medical record system terminal 3 receives the image quality accuracy screen data from the electronic medical record system server 5 and displays it on the monitor 31 (step S57).

  An example of the image quality accuracy screen is shown in FIG. The example of FIG. 9 includes an inspection data display unit 900, an imaging device data display unit 902, and a confirmation monitor / data display unit 904. The purchase date, manufacturer, and display brightness included in the confirmation monitor / data display unit 904 are extracted from a terminal monitor DB (not shown) based on the terminal ID. For example, a user who is a doctor can know in what environment the specialist has confirmed the image by viewing the data displayed on this screen. In addition, for example, there may be included data related to an image check result by a professional engineer such as a check result of a film display image and a check result of a monitor display image.

  FIG. 10 shows the process (step S53 (FIG. 8): Yes route) transferred through the terminal A. First, the electronic medical record system server program 53 of the electronic medical record system server 5 generates monitor information reception page data and transmits it to the electronic medical record system terminal 3 (FIG. 10: step S61). The electronic medical record system client program 35 of the electronic medical record system terminal 3 receives the monitor information reception page data from the electronic medical record system server 5 and displays it on the monitor 31 (step S63).

  Although not shown, the monitor information reception page includes an object for attaching a file generated by the monitor information acquisition program 33 of the electronic medical record system terminal 3. The monitor information acquisition program 33 acquires information related to the monitor 31 according to a user instruction or periodically and stores it in a predetermined file. For example, a user who is a doctor refers to and designates a file generated by the monitor information acquisition program 33 on the monitor information reception page, and performs an operation of instructing transmission to the electronic medical record system server 5. Note that a data input field may be provided on the monitor information reception page so that the user can input part or all of the information to be transmitted. Further, the predetermined file may be automatically read out and transmitted to the electronic medical record system server 5 by a technique such as ActiveX (trademark of Microsoft Corporation).

  Then, the electronic medical record system client program 35 of the electronic medical record system terminal 3 receives the information on the monitor 31 and transmits it to the electronic medical record system server 5 (step S65). The electronic medical record system server program 53 of the electronic medical record system server 5 receives the information of the monitor 31 from the electronic medical record system terminal 3 and temporarily stores it in the storage device (step S67).

  Then, the electronic medical record system server program 53 searches the medical record DB monitor information table (FIG. 5) based on the document ID received in step S43 (FIG. 8), and at the time of inspection (at the time of image confirmation by a technician). The monitor information and image compression rate used are extracted and temporarily stored in the storage device (step S69).

  The electronic medical record system server program 53 transmits a request for image data to the image system server 9 (step S71). At this time, in step S23 (FIG. 6), the corresponding image ID is specified from the quality check data (FIG. 7) stored in the electronic medical record DB 51 and transmitted together.

  The image system server program 93 of the image system server 9 receives a request for image data including an image ID from the electronic medical record system server 5 (step S73). Then, the image system server program 93 extracts the image and compression rate data from the image DB 91 and transmits them to the electronic medical record system server 5 (step S75). The electronic medical record system server program 53 of the electronic medical record system server 5 receives the image and compression rate data from the image system server 9 and temporarily stores them in the storage device (step S77).

  Then, the electronic medical record system server program 53 compares the monitor information and image compression rate at the time of inspection extracted in step S69 with the monitor information and image compression rate received in steps S67 and S77, Comparison data obtained by extracting items having different values is generated and temporarily stored in the storage device (step S79). For items having different values, the difference may be obtained as long as it is a numerical value. In the present embodiment, data relating to deterioration in the same monitor is included in the comparison data. For example, when the luminance difference (value in the luminance difference column 518 (FIG. 5) in the chart information monitor information table) is not 0 in the monitor information at the time of inspection, the luminance difference is included in the comparison data.

  Then, the electronic medical record system server program 53 generates image page data based on the image data received in step S77 and the comparison result in step S79, and transmits it to the electronic medical record system terminal 3 (step S81). Here, the reason based on the comparison result in step S79 is that, when there is an item having a different value or a luminance difference, an object for shifting to a page displaying the comparison result is included in the image page.

  The electronic medical record system client program 35 of the electronic medical record system terminal 3 receives the image page data from the electronic medical record system server 5 and displays it on the monitor 31 (step S83).

  FIG. 11 shows an example of the image page. In the example of FIG. 11, a medical image captured by a CT imaging apparatus or the like is shown, and a “!” Button 1100 is included in the upper right of the page. The “!” Button 1100 is an object for shifting to the page displaying the comparison result described above. For example, the user who is a doctor clicks the “!” Button 1100 in order to know the difference between the display quality of the image he / she is currently viewing and the display quality of the image confirmed by the professional engineer.

  Returning to the description of FIG. 10, the electronic medical record system client program 35 of the electronic medical record system terminal 3 accepts a monitor comparison page display instruction by clicking the “!” Button 1100 (FIG. 11) (FIG. 10: step S85). Then, the electronic medical record system client program 35 transmits a monitor comparison page data request to the electronic medical record system 5 (step S87). The electronic medical record system server program 53 of the electronic medical record system server 5 receives a request for monitor comparison page data from the electronic medical record system terminal 3 (step S89).

  Then, the electronic medical record system server program 53 of the electronic medical record system server 5 generates monitor comparison page data based on the comparison data generated in step S79 and transmits it to the electronic medical record system terminal 3 (step S91). The electronic medical record system client program 35 of the electronic medical record system terminal 3 receives the monitor comparison page data from the electronic medical record system server 5 and displays it on the monitor 31 (step S93).

  FIG. 12 shows an example of the monitor comparison page. In the example of FIG. 12, the monitor (device name) difference (item number 1), the brightness difference of the monitor used by the specialist (item number 2), the image compression rate difference (item number 3), the monitor Data relating to the difference in resolution (item 4) and the difference in brightness (luminance) of the monitor (item 5) are shown. The items other than item number 2 are shown separately for “confirmation” and “for display”, but “confirmation” shows data on the monitor 71 which is a monitor used for confirmation by an expert engineer, for example. “For display” shows data on the monitor 31 which is a monitor used by the user to view the image page and the monitor comparison page shown in FIG. For example, a user who is a doctor can determine whether it is appropriate to look at such data and see the image page (FIG. 11) displayed on the monitor 31 for diagnosis.

  It should be noted that such a monitor comparison page is used even when there is no difference in luminance between the confirmation monitor (monitor 71), a difference in image compression rate, or a difference in specifications between the confirmation monitor and the display monitor (monitor 31). You may make it display. In that case, the “!” Button 1100 may be unconditionally included in the image page (FIG. 11), and the process of step S79 (FIG. 10) may be performed after step S89.

  In this way, for example, a user who is a doctor is presented with an image and data related to the display of the image.

  In the description so far, the electronic medical record system server program 53 of the electronic medical record system server 5 and the electronic medical record system client program 35 of the electronic medical record system terminal 3 use the Web server function and the Web browser function. However, these may be dedicated client / server type software.

  In this case, the processing from step S61 to step S65 (FIG. 10) can be changed as follows. First, the electronic medical record system server program 53 of the electronic medical record system server 5 transmits a request for monitor information to the electronic medical record system terminal 3 (step S61). The electronic medical record system client program 35 of the electronic medical record system terminal 3 receives a request for monitor information from the electronic medical record system server 5 (step S63). The electronic medical record system client program 35 transmits monitor information based on the file generated by the monitor information acquisition program 33 to the electronic medical record system server 5 (step S65). In this way, communication of monitor information (for display) is automatically performed without bothering the user.

  In the same processing step, the electronic medical record system server program 53 of the electronic medical record system server 5 extracts the information of the corresponding monitor from the terminal monitor DB (not shown) using the user login ID or the like. Also good. In this way, the electronic medical record system server 5 can acquire monitor information without performing communication processing.
