Hereinafter, embodiments of the present invention will be described with reference to the drawings.
(First embodiment)
FIG. 1 is a block diagram showing an overall configuration of a medical image observation system to which the computer system analysis apparatus according to the first embodiment is applied. This medical image observation system is introduced in a medical facility having a three-story East Building and West Building.

  A server 1 is arranged on the first floor of the east building. A plurality of client viewers 2 are arranged in the medical facility. For example, client viewers 2-1 to 2-5 are arranged in the rooms A to E on the second and third floors of the east building and the first, second and third floors of the west building, respectively. When it is necessary to distinguish each of the plurality of client viewers 2, it is described as “client viewer 2-1” or “client viewer 2-2”, but when there is no need to distinguish, “client viewer 2” is used. It will be described.

  The server 1 and the client viewer 2 can communicate with each other via a LAN (Local Area Network) including the routers 3-1 to 3-5 and the hub 4. In addition, inspection devices such as CT (Computed Tomography) 5, MR (Magnetic Resonance) 6 and DR (Digital Radiography) 7 are arranged on the first floor of the East Building, and are connected to the LAN via the router 3-1. .

  An access router 8 is arranged on the first floor of the west building. The access router 8 is connected to the LAN via the router 3-4. The access router 8 is connected to the public network 9. The access router 8 can communicate with the access router 10 arranged in the maintenance center via the public network 9. A maintenance terminal 11 is connected to the access router 10, and the maintenance terminal 11 can access the LAN of the medical facility via the access router 10, the public network 9 and the access router 8.

  In this medical image observation system, the server 1 collects and stores medical image data generated by CT5, MR6, and DR7. A user such as a doctor or a nurse can access the server 1 using the client viewer 2 and arbitrarily display a medical image on the monitor of the client viewer 2.

FIG. 2 is a block diagram showing the configuration of the server 1 in FIG.
As shown in FIG. 2, the server 1 includes a communication unit 101, an image collection unit 102, an image storage unit 103, an image distribution unit 104, a use state information storage unit 105, a use state monitoring unit 106, an arrangement information storage unit 107, a floor plan. An information storage unit 108, an unreasonable state detection unit 109, a low image quality warning unit 110, a resolution plan creation unit 111, an input device 112, and a display device 113 are included.

  The server 1 can use, for example, a general-purpose computer device as basic hardware. Then, the image collection unit 102, the image distribution unit 104, the usage state monitoring unit 106, the irrational state detection unit 109, the low image quality warning unit 110, and the resolution plan creation unit 111 execute a program on the processor mounted on the computer device. This can be realized. At this time, the server 1 may be realized by installing the above program in a computer device in advance, or may be recorded on a removable recording medium such as a CD-ROM or the above program via a network. The program may be distributed and installed as appropriate in the computer device. The image storage unit 103, the usage state information storage unit 105, the arrangement information storage unit 107, and the floor plan information storage unit 108 are externally attached to a storage device such as a memory or a hard disk device built in the computer device, or the computer device. Further, it can be realized by appropriately using a storage device such as a memory or a hard disk device, or a removable recording medium such as an optical disk.

  The communication unit 101 is connected to the router 3-1, and performs communication via a LAN. The image collection unit 102 collects medical image data generated by CT5, MR6, and DR7 via a LAN. The image collection unit 102 stores the collected medical image data in the image storage unit 103. The image distribution unit 104 transmits medical image data stored in the image storage unit 103 in response to an image transmission request from the client viewer 2. When receiving an access from the client viewer 2, the image distribution unit 104 receives device information related to the client viewer 2 and user information related to the user of the client viewer 2. The device information indicates the specifications of the CPU provided in the client viewer 2, the memory capacity, the monitor resolution, and the like. The user information indicates a user name, a job type of the user, and the like. The image distribution unit 104 stores the received device information, user information, and image transmission request in the usage state information storage unit 105. The usage state monitoring unit 106 acquires device information, user information, and an image transmission request from the usage state information storage unit 105, and monitors the usage state of the client viewer 2 based on these information.

  The arrangement information storage unit 107 stores arrangement information. The arrangement information is information describing the MAC address, IP address, device name, and installation location of the client viewer 2, the routers 3-1 to 3-5, and the hub 4, as shown in FIG. All of the arrangement information may be created by an administrator or the like, but a function of automatically creating a part of the arrangement information can also be provided. For example, since the information regarding the routers 3-1 to 3-5 and the hub 4 should be known at the time of LAN construction, if it is described in the arrangement information, “location 1” and “location 2” for the client viewer 2 "Can be automatically determined from the location of the router or hub to which each client viewer 2 is connected. However, when the client viewer 2 is installed at a location different from the connection destination router or hub, such as the client viewer 2-5, it is necessary to manually set “location 1” and “location 2”. . Further, “place 3” needs to be set manually.

  The floor plan information storage unit 108 stores floor plan information. The floor plan information is information representing a floor plan as shown in FIG. 4, for example, showing the floor plan of each medical facility. The floor plan information can be automatically created with a function that can easily create a floor plan, or can be used when the floor plan of a medical facility can be obtained electronically.

The unreasonable state detection unit 109 detects that the use state of the client viewer 2 is an unreasonable state based on the monitoring result of the use state monitoring unit 106, the arrangement information, and the floor plan information. The irrational states detected by the irrational state determination unit 109 are the following four states.
(1) The resolution of the monitor of the client viewer 2 requesting medical image data is lower than the resolution of the client viewer 2 that is normally used by the user of the client viewer 2. Hereinafter, this state is referred to as a first irrational state.
(2) A client viewer 2 that frequently displays high-definition medical images compared to the resolution of the monitor (hereinafter referred to as an overloaded client viewer 2), and a medical image that is low-definition compared to the resolution of the monitor frequently. The client viewer 2 that displays or uses less frequently (hereinafter referred to as the low-load client viewer 2) is mixed, and the monitor resolution of the low-load client viewer 2 is higher than the resolution of the client viewer 2 that is overloaded. Is also in a large state. Hereinafter, this state is referred to as a second irrational state.
(3) A state in which the usage frequency by a plurality of users is uneven between the client viewers 2. Hereinafter, this state is referred to as a third irrational state.
(4) The client viewer 2 that satisfies the user's usage condition is that the amount of movement that the user of the client viewer 2 in use moves from the home location to the installation location of the client viewer 2 is a certain amount or more and is smaller. There is a state. Hereinafter, this state is referred to as a fourth irrational state.

  The low image quality warning unit 110 transmits low image quality warning information for causing the client viewer 2 to display a warning in response to the detection of the first irrational state by the irrational state detection unit 109. When the second to fourth irrational states are detected by the irrational state detection unit 109, the elimination plan creation unit 111 creates a plan for eliminating those irrationals.

  As the input device 112, for example, a keyboard or a mouse can be applied. The input device 112 accepts execution instructions for diagnosis of the second to fourth irrational states. As the display device 113, for example, a liquid crystal display can be applied. The display device 113 displays the resolution plan created by the resolution plan creation unit 111.

Next, the operation of the medical image observation system configured as described above will be described focusing on the operation of the server 1.
When a user such as a doctor or nurse wants to observe a medical image, the client 1 is used to access the server 1. In this case, in the server 1, the image distribution unit 104, the usage state monitoring unit 106, the irrational state detection unit 109, and the low image quality warning unit 110 execute an image distribution process as shown in FIG. In the following, the current access source in the client viewer 2 is referred to as an access source viewer.

  In step Sa <b> 1, the image distribution unit 104 receives user information and device information sent from the access source viewer, and stores the user information and device information in the use state information storage unit 105. In step Sa2, the image distribution unit 104 transmits a list of medical image data stored in the image storage unit 103 to the access source viewer in response to a request from the access source viewer. In step Sa3, the image distribution unit 104 receives an image transmission request transmitted from the access source viewer based on the list, and associates the image transmission request with the user information and device information to use state information storage unit. Save to 105. Thus, since the user information, the device information, and the image transmission request are stored in the usage state information storage unit 105 in association with each other, which user is in which client viewer 2 and which medical image is based on the information. It is possible to determine whether or not an image of which part is captured by which modality is observed.

  In step Sa4, the use state monitoring unit 106 analyzes the information stored in the use state information storage unit 105, thereby determining the resolution of the monitor of the client viewer 2 that is currently used by the user of the current access source viewer. . In step Sa5, the use state monitoring unit 106 confirms whether or not the determined resolution and the resolution of the monitor of the access source viewer are comparable.

  If the confirmation result in step Sa5 is NO, the process proceeds from step Sa5 to step Sa6. In step Sa6, the low image quality warning unit 110 transmits the low image quality warning information to the access source viewer. The low image quality warning information is information for displaying a low image quality warning screen on the access source viewer. The low image quality warning screen indicates that even if the user requests an image with the same resolution as the image that the user normally sees, the image cannot be displayed as usual due to a problem with the specifications, and the image quality may be deteriorated. Show. Specifically, a user who normally observes a CT image of 512 pixels × 512 pixels on a monitor having a resolution of 512 pixels × 512 pixels or more can access an access source viewer having a low resolution monitor such as a PDA. When accessing by using, it is not possible to display at a resolution of 512 pixels × 512 pixels, and the display becomes lower quality than usual. To alert the user.

  From step Sa6, the process proceeds to step Sa7. If the confirmation result at step Sa5 is YES, the process proceeds from step Sa5 to step Sa7. In step Sa7, the image distribution unit 104 reads the medical image data specified by the image transmission request from the image storage unit 103 and transmits it to the requesting viewer.

  As described above, in response to the detection of the first irrational state in the process of transmitting the medical image data in response to the request from the client viewer 2, the image is displayed with lower image quality than usual. The user is warned that there is a risk.

  The diagnosis of the second to fourth irrational states is performed in response to an execution request from the input device 112 by the maintenance staff.

  In response to the request for execution of the diagnosis for the second unreasonable state, the use state monitoring unit 106, the unreasonable state detection unit 109, and the cancellation plan creation unit 111 execute the use diagnosis as shown in FIG. The

  In step Sb1, the usage state monitoring unit 106 analyzes the information stored in the usage state information storage unit 105, thereby obtaining statistics of the user and the image transmission request.

  In step Sb2, the use state monitoring unit 106 determines whether the diagnosis of the second unreasonable state is performed based on the user or the image. This is specified by the user together with a diagnosis execution request for the second unreasonable state, for example. If the user criterion is specified, the use state monitoring unit 106 proceeds from step Sb2 to step Sb3. In step Sb3, the use state monitoring unit 106 classifies each of the client viewers 2 as one of a low load, an appropriate load, and an overload based on a user who frequently uses each of the client viewers 2. Specifically, for example, when a user who frequently uses a certain client viewer 2 is a person who observes an image having a resolution lower than the resolution of the monitor of the client viewer 2, the client viewer 2 is loaded with low load. Classify. When a user who frequently uses a certain client viewer 2 is a person who observes an image with a resolution similar to the resolution of the monitor of the client viewer 2, the client viewer 2 is classified into an appropriate load. When a user who frequently uses a certain client viewer 2 is a person who observes an image with a resolution higher than the resolution of the monitor of the client viewer 2, the client viewer 2 is classified as overloaded. When there is no user who frequently uses a certain client viewer 2, this client viewer 2 is classified into a low load. Note that the resolution required by the user can be determined from, for example, the job type of the user. That is, doctors who perform interpretation diagnosis require high resolution, but nurses and the like need only a relatively low resolution. Therefore, a setting table describing the relationship between such job types and resolutions is prepared in the server 1.

  On the other hand, if the image reference is designated, the process proceeds from step Sb2 to step Sb4. In step Sb4, the use state monitoring unit 106 classifies each of the client viewers 2 as one of a low load, an appropriate load, and an overload based on a medical image frequently displayed on each of the client viewers 2. Specifically, for example, when the resolution of a medical image frequently displayed on a certain client viewer 2 is lower than the resolution of the monitor of the client viewer 2, the client viewer 2 is classified into a low load. When a medical image frequently displayed on a certain client viewer 2 has a resolution comparable to the resolution of the monitor of the client viewer 2, the client viewer 2 is classified as an appropriate load. When a medical image frequently displayed on a certain client viewer 2 has a resolution higher than the resolution of the monitor of the client viewer 2, the client viewer 2 is classified as overloaded. When a medical image is hardly displayed on a certain client viewer 2, the client viewer 2 is classified into a low load.

  From step Sb3 or step Sb4, the process proceeds to step Sb5. In step Sb5, the unreasonable state detection unit 109 refers to the classification result in step Sb3 or step Sb4, and the resolution of the client viewer 2 classified as overloaded is the resolution of the client viewer 2 classified into low load. A combination of the client viewers 2 that is larger than that is searched. Here, if a corresponding combination is found, the operation of the client viewer 2 is in the second unreasonable state. In addition, when there are a plurality of client viewers 2 classified as low load, the client viewer 2 having a resolution necessary for displaying an image displayed by the client viewer 2 classified as high load is selected. Good. If there is no client viewer 2 having the required resolution as described above, the client viewer 2 having the closest display capability may be selected.

  Therefore, in step Sb6, the unreasonable state detection unit 109 confirms whether or not a corresponding combination has been found. If the confirmation result in step Sb6 is YES, the process proceeds from step Sa6 to step Sa7. In step Sb7, the cancellation plan creation unit 111 creates a proposal image for operation change and causes the display device 113 to display the proposal image. The proposed image here prompts to replace the monitor of each client viewer 2 included in the combination found in step Sb5, or to some of the users of the client viewer 2 classified as overloaded. It is conceivable that the client viewer 2 classified as low load is urged to be used.

  FIG. 7 is a diagram illustrating a specific example of a situation in which the second irrational state is detected by the diagnosis based on the user standard. In the situation shown in FIG. 7, the client viewer 2-1 installed in the room A has a lower monitor resolution than the client viewer 2-2 installed in the room B. In addition, the client viewer 2-1 is frequently used by a user who needs a high-resolution monitor for interpretation. The client viewer 2-2 is frequently used by a user who does not need a high-resolution monitor for reference or the like. In such a situation, the display device 113 of the server 1 displays an image proposing the exchange between the client viewer 2-1 and the client viewer 2-2.

  FIG. 8 is a diagram illustrating a specific example of a situation in which the second unreasonable state is detected by diagnosis based on an image. In the situation shown in FIG. 8, a monitor having a resolution of 512 pixels × 512 pixels as shown in FIG. 8A has a CT image of 512 pixels × 512 pixels as 2 × 2 as shown in FIG. 8B. Often used to arrange and display. Further, a monitor having a resolution of 1024 pixels × 1024 pixels as shown in FIG. 8C displays MR images of 256 pixels × 256 pixels arranged in 2 × 2 as shown in FIG. 8D. Used frequently. In such a situation, by replacing these monitors, the optimum environment for CT interpretation can be obtained while satisfying the conditions necessary for MR interpretation. Therefore, an image for making such a proposal is displayed on the display device 113.

  In each of the above specific examples, the screen for proposing the replacement of the monitor is displayed, but the screen for proposing the change of the monitor to be used may be used. Further, the monitor of the client viewer 2 classified as an appropriate load may be replaced or used.

  By the way, in many cases, a certain user often observes the same kind of images in the same arrangement. Therefore, when the server 1 performs the following processing when accessed by a user who uses the medical image observation system for the first time, the user can use the appropriate client viewer 2 and the second inconvenience is caused. The possibility that a rational state will occur can be reduced. That is, the server 1 causes the user to specify the type of image to be observed and the preferred arrangement. The server 1 calculates the resolution necessary for display in the display format preferred by the user based on the user's designation. The server 1 selects a client viewer 2 suitable for display at the calculated resolution. Then, the server 1 displays an image indicating that the selected client viewer 2 is suitable for use by the user on the display unit of the client viewer 2 used by the user.

  Now, in response to the request for execution of the diagnosis for the third irrational state, the use state monitoring unit 106, the irrational state detection unit 109, and the cancellation plan creation unit 111 perform frequency diagnosis as shown in FIG. Executed.

  In step Sc <b> 1, the usage state monitoring unit 106 analyzes the user who uses each client viewer 2 and the usage frequency for each client viewer 2 based on the information stored in the usage state information storage unit 105.

  In step Sc2 and step Sc3, the unreasonable state detection unit 109 has a client viewer 2 that is frequently used by a plurality of people and a client viewer 2 that is frequently used by a plurality of people based on the above analysis results. Check whether or not. Here, when there is no client viewer 2 with high usage frequency and client viewer 2 with low usage frequency, or there is only one of the client viewer 2 with high usage frequency and the client viewer 2 with low usage frequency. Does not detect that the third irrational state exists, and ends the frequency diagnosis as it is.

  On the other hand, if there is a client viewer 2 with a high usage frequency and a client viewer 2 with a low usage frequency, the usage frequency varies between the client viewers 2 and the third irrational state occurs. It will be. Therefore, in this case, the cancellation plan creation unit 111 causes the display device 113 to display an operation change proposal image in step Sc4. Here, the proposed image is a message that prompts the client viewer 2 with low usage frequency to be moved to a room where the client viewer 2 with high usage frequency is installed, or a part of the users of the client viewer 2 with high usage frequency. It is considered that the client viewer 2 that is used less frequently is encouraged to be used.

  FIG. 10A is a diagram illustrating a specific example of a situation in which the third irrational state is detected. In the situation shown in FIG. 10A, the client viewer 2-1 installed in the room A is frequently used by a plurality of users. On the other hand, the frequency of use of the client viewer 2-2 installed in the room B is low. In such a situation, the usage frequency of the client viewers 2-1 and 2-2 can be leveled by moving the client viewer 2-2 to the room A as shown in FIG. It is. Therefore, the display device 113 of the server 1 displays an image proposing to move the client viewer 2-2 to the room A.

By the way, in a medical image observation system including a large number of client viewers 2, a plurality of client viewers 2 with low usage frequency may be found.
FIG. 11A is a diagram showing another specific example of the situation in which the third irrational state is detected. In the situation shown in FIG. 11A, the client viewer 2-1 installed in the room A is frequently used by a plurality of users. On the other hand, the frequency of use of the client viewer 2-2 installed in the room B and the client viewer 2-3 installed in the room C is low.

  At this time, an image suggesting that the client viewer 2-2 or the client viewer 2-3 be moved to the room A may be displayed on the display device 113 of the server 1. Alternatively, narrowing down may be performed based on a predetermined condition. For example, if the condition is based on the specifications of the client viewer 2, as shown in FIG. 11B, the client viewer 2-3 having the same specifications as the client viewer 2-1 is moved. Display an image that suggests.

  Now, in response to the request for execution of the diagnosis for the fourth irrational state, the usage amount monitoring unit 106, the irrational state detection unit 109, and the cancellation plan creation unit 111 perform the movement amount diagnosis as shown in FIG. Is executed.

  In step Sd1, the usage status monitoring unit 106 uses the client viewer 2 frequently used by each user for each user who has used the client viewer 2 based on the information stored in the usage status information storage unit 105. Analyzing the amount of movement from the home location of each user until. As the home location of each user, a location where the user is usually present may be registered in advance. The movement amount can be estimated by referring to information stored in the arrangement information storage unit 107 and the floor plan information storage unit 108.

  In step Sd2, the unreasonable state detection unit 109 refers to the analysis result and searches for a user whose movement amount is a certain amount or more. In step Sd3, the unreasonable state detection unit 109 confirms whether or not the corresponding user has been found.

  If the confirmation result in step Sd3 is NO, there is no fourth irrational state, and the movement amount diagnosis is terminated as it is. On the other hand, if the confirmation result in step Sd3 is YES, the process proceeds from step Sb3 to step Sb4. In step Sb4, the unreasonable state detection unit 109 searches for the client viewer 2 that satisfies the use condition of the user found in step Sb2 and is installed near the home location of the user. In step Sd5, the unreasonable state detection unit 109 confirms whether or not the corresponding client viewer 2 has been found.

  If the confirmation result in step Sd5 is NO, there is no fourth irrational state, and the movement amount diagnosis is terminated as it is. However, if the confirmation result in step Sd5 is YES, a fourth irrational state has occurred. Therefore, in this case, the process proceeds from step Sd5 to step Sd6. In step Sd6, the cancellation plan creation unit 111 creates a proposal image for operation change and displays the proposal image on the display device 113. It is conceivable that the proposed image here prompts the user found in step Sd2 to use the client viewer 2 found in step Sd4.

  Specifically, a situation in which a user who performs an interpretation diagnosis interprets using a client viewer 2 installed far from the user's home location among a plurality of client viewers 2 that can provide an equivalent interpretation environment. Then, it is more efficient to use the client viewer 2 that is closer to the home location of the user among the plurality of client viewers 2 that can provide the above-described equivalent interpretation environment. Therefore, an image proposing such an operation change is displayed on the display device 113 of the server 1.

  It is also conceivable that the remote client viewer 2 is intentionally used for some reason. For example, it may be desirable not to judge this as an unreasonable state when it is necessary to perform an interpretation urgently while visiting a different medical office. In addition, if a client viewer 2 that is far away is used by a certain user many times, the user may intentionally use the client viewer 2, and this is not judged as an irrational state. Sometimes it is desirable. Therefore, the number of times of use may be taken into account in the movement amount diagnosis. For example, in step Sd2, the above two states are detected as the fourth unreasonable state by searching only for users whose number of uses is greater than or equal to the first threshold value and less than the second threshold value. You may not make it.

  As described above, according to the first embodiment, an unreasonable state related to the use of the client viewer 2 is detected. Therefore, when such an unreasonable state is detected, for example, an administrator of the medical image observation system can take a measure to eliminate the unreasonable state, thereby constructing a simple and efficient medical image observation system. can do. Furthermore, according to the first embodiment, since the plan for eliminating the irrational state is created and displayed, the administrator determines what measures should be taken to eliminate the irrational state. However, it is possible to further reduce the burden on the administrator.

(Second Embodiment)
The overall configuration of the medical image observation system to which the computer system analysis apparatus according to the second embodiment is applied is substantially the same as that of the first embodiment. However, a server 21 is provided instead of the server 1.

FIG. 13 is a block diagram showing the configuration of the server 21. In FIG. 13, the same parts as those in FIG. 2 are denoted by the same reference numerals, and detailed description thereof is omitted.
As shown in FIG. 13, the server 21 includes a communication unit 101, an image collection unit 102, an image storage unit 103, an image distribution unit 104, a usage state information storage unit 105, a usage state monitoring unit 106, an arrangement information storage unit 107, a floor plan. An information storage unit 108, an input device 112, a display device 113, an unreasonable state detection unit 211 and a cancellation plan creation unit 212 are included.

  That is, the server 21 does not have the low image quality warning unit 110 in the server 1. The server 21 includes an irrational state detection unit 211 and a cancellation plan creation unit 212 instead of the irrational state detection unit 109 and the cancellation plan creation unit 111 in the server 1.

  The irrational state detection unit 211 detects a state in which the client viewer 2 that does not match the user is being used by the user as an irrational state. When the above-described irrational state is detected, the cancellation plan creation unit 212 creates a plan for eliminating the irrational state.

  In the arrangement information storage unit 107, the capability (monitor resolution, etc.) of each client viewer 2 is additionally written.

Next, the operation of the medical image observation system configured as described above will be described focusing on the operation of the server 21.
The client viewer 2 logged in by the user (hereinafter referred to as the login destination viewer 2) sends the user information relating to the logged-in user (hereinafter referred to as the login user) and the identification information of the login destination viewer 2 to the server 21. Send. Then, in response to the arrival of the user information and the identification information, the non-conformity diagnosis as shown in FIG. 14 is executed by the unreasonable state detection unit 211 and the cancellation plan creation unit 212.

  In step Se <b> 1, the unreasonable state detection unit 211 acquires the user information and identification information received by the communication unit 101 from the communication unit 101. In step Se2, the unreasonable state detection unit 211 confirms whether or not the login destination viewer 2 is suitable for the login user based on the user information and the identification information. Whether or not the login destination viewer 2 is suitable for the login user can be confirmed with reference to a setting table as shown in FIG. 15, for example. The setting table shown in FIG. 15 describes the monitor type (resolution ability) required by the user of each job type for each job type of the user, and is determined by, for example, the administrator. Based on this setting table, for example, if the login user is a doctor, if the login destination viewer 2 has a high-resolution monitor or a medium-resolution monitor, it is determined to be suitable (YES), and if it has a low-resolution monitor, it is not suitable. It is determined that it is (NO). The type of monitor provided in the login destination viewer 2 can be determined with reference to the arrangement information storage unit 107.

  If the confirmation result in step Se2 is YES, it is determined that an unreasonable state has not occurred, and this nonconformity diagnosis is terminated as it is without performing the processing after step Se3 described later. If the confirmation result at step Se2 is NO, the process proceeds from step Se2 to step Se3. In step Se3, the cancellation plan creation unit 212 searches for the client viewer 2 that matches the login user. Specifically, for example, the client viewer 2 having a monitor of a monitor type suitable for the job type of the user is searched.

  In step Se3, the cancellation plan creation unit 212 confirms the number of client viewers 2 detected by the search, that is, the number of detections. When the number of detection is 0, the process proceeds from step Se4 to step Se5. In step Se <b> 5, the resolution plan creation unit 212 displays an image that warns that the login user and the login destination viewer 2 are incompatible with each other on the display device 113. This image notifies that the use of the login destination viewer 2 by the login user is unreasonable. That is, since an alternative monitor for eliminating the irrational state is not found, only the irrational state is notified.

  When the number of detection is 1, the process proceeds from step Se4 to step Se6. In step Se6, the cancellation plan creation unit 212 selects one detected client viewer 2 as a candidate viewer.

  If the number of detections is plural, the process proceeds from step Se4 to step Se7. In step Se <b> 7, the cancellation plan creation unit 212 confirms the narrowing conditions. As a narrowing-down condition, for example, the administrator designates in advance one of “none”, “resolution”, “distance”, and “usage frequency”.

  If the narrowing condition is “none”, the process proceeds from step Se7 to step Se8. In step Se8, the cancellation plan creation unit 212 selects all detected client viewers 2 as candidate viewers. That is, at this time, candidate viewers are not narrowed down.

  If the narrowing condition is “resolution”, the process proceeds from step Se7 to step Se9. In step Se9, the cancellation plan creation unit 212 selects a candidate viewer from the detected client viewers 2 in consideration of the resolution. Specifically, the client viewer 2 having a higher-resolution monitor among the detected client viewers 2 is selected as a candidate viewer.

  If the narrowing condition is “distance”, the process proceeds from step Se7 to step Se10. In step Se10, the cancellation plan creation unit 212 selects a candidate viewer from among the detected client viewers 2 in consideration of the separation distance from the login destination viewer 2. Specifically, the client viewer 2 arranged closer to the login destination viewer 2 among the detected client viewers 2 is selected as a candidate viewer.

  If the narrowing condition is “usage frequency”, the process proceeds from step Se7 to step Se11. In step Se11, the cancellation plan creation unit 212 selects a candidate viewer from the detected client viewers in consideration of the usage frequency. Specifically, among the detected client viewers, the client viewer 2 that is used less frequently than others is selected as a candidate viewer.

  After the candidate viewer is selected in any one of Step Se6 and Steps Se8 to 11, the process proceeds from each step to Step Se12. In step Se <b> 12, the cancellation plan creation unit 212 creates a proposal image for operation change and displays the proposal image on the display device 113. The proposed image here can be considered to encourage the exchange of the monitor of the login destination viewer 2 and the monitor of the candidate viewer, or to encourage the login user to use the candidate viewer.

  FIG. 16 is a diagram illustrating a specific example of a situation where an unreasonable state is detected. In the situation shown in FIG. 16, client viewers 2-11, 2-12, and 2-13 are installed in the room X. In room Y, client viewers 2-14, 2-15, and 2-16 are installed. The client viewers 2-11 and 2-12 have high-resolution monitors. The client viewers 2-13, 2-14, and 2-15 have a medium resolution monitor. The client viewer 2-16 includes a low-resolution monitor. The client viewer 2-11 is frequently used by a user who is a doctor. The client viewer 2-15 is frequently used by users who are nurses. The client viewers 2-12, 2-13, and 2-14 are used less frequently.

  In such a situation, it is assumed that the user U who is a doctor logs in to the client viewer 2-16. According to FIG. 15, a doctor needs a high resolution monitor or a medium resolution monitor, but the monitor of the client viewer 2-16 has a low resolution, and the client viewer 2-16 is incompatible with the user U.

  At this time, the client viewers 2-11, 2-12, 2-13, 2-14, and 2-15 are provided with the high-resolution monitor or the medium-resolution monitor required by the user U. Detected as If the filtering condition is “None”, for example, a proposal image that displays a list of these client viewers 2-11, 2-12, 2-13, 2-14, and 2-15 as candidate viewers is displayed. To do. If the condition for narrowing down is “resolution”, the candidate viewers are narrowed down to client viewers 2-11 and 2-12 having high-resolution monitors. If the narrowing condition is “distance”, the candidate viewers are narrowed down to the client viewers 2-14 and 2-15 installed in the same room as the client viewer 2-16.

Note that the cancellation plan creation unit 212 may narrow down candidate viewers based on a plurality of conditions. A specific example will be described below.
In the situation shown in FIG. 17, the client viewer 2-11 is frequently used. The client viewers 2-12, 2-14, 2-15, and 2-16 are moderately used. The client viewer 2-13 is used less frequently.

  In such a situation, it is assumed that the user U who is a doctor logs in to the client viewer 2-16. In this case, the cancellation plan creation unit 212 gives scores to all the client viewers 2 including the client viewer 2-16 for each item of resolution, usage frequency, and distance from the login destination viewer 2 as shown in FIG. wear. In the example of FIG. 18, each item is evaluated in three stages (9 points, 5 points, 1 point). Then, the cancellation plan creation unit 212 calculates the total score by adding the scores of each item after weighting with the coefficient for each item. In the example of FIG. 18, the coefficient is “3”, the usage frequency is “2”, and the distance is “1”. The cancellation plan creation unit 212 selects the client viewer 2 with a high total score as a candidate viewer. Only the client viewer 2 with the highest score may be selected, or some client viewers 2 with higher scores may be selected.

  As described above, according to the second embodiment, when there are a plurality of candidate viewers, the candidates are narrowed down to more appropriate candidates based on the attributes of these candidate viewers, and are proposed to the administrator. As a result, the burden on the administrator is further reduced.
