20130268587
The present invention relates to an information processing device and a data management system.
In recent years, in the medical field, there has been used a system to store medical-use images taken with radiation or the like as digital data. Usually, medical-use images are stored in an image management server installed in a hospital, and image data thereof in the image management server is loaded into client terminals so that the medical-use images are displayed on the client terminals.
However, in the case where an image management server is installed in a hospital, an expensive high-spec PC (Personal Computer) is necessary to operate as a server, and hence installation of an image management server costs much. Furthermore, in order that data in a hospital is looked at from the outside, it is necessary to make the image management server keep operating because images cannot be looked at when power of the image management server is off.
Then, to reduce the cost of storing and managing data to be paid by medical facilities, there has been proposed a medical data storage system to transmit medical data, such as medical-use image data taken at medical facilities, to a data center connected to the medical facilities via a network so as to accumulate and manage the medical data at the data center. (Refer to Patent Document 1 and Patent Document 2).

The communication unit 44 is constituted of a network interface or the like, and transmits/receives data to/from an external device connected to the communication unit 44 via the internal network 7A and the communication network N.
The RAM 45 forms a work area to temporarily store various programs, input/output data, parameters and the like read from the storage unit 46 in various processes executed and controlled by the control unit 41.
The storage unit 46 is constituted of an HDD, a nonvolatile semiconductor memory or the like, and stores various process programs, and parameters, files and the like necessary for execution of the programs. More specifically, the storage unit 46 stores the application program 461, the primary DB 462 and the like.
The application program 461 is a program (the application program 163) to perform a process to use the data management system 100 in the terminal device 4A, and is downloaded from the data management server 1.
The primary DB 462 contains a facility information table T3 (see
The GW 47 acquires image data and accessory information (the patient ID, the examination ID, the patient name, the examination date & time, the image type and the like) on the image data from the examination device 5A. That is, the GW 47 functions as an acquirement unit. The accessory information may be inputted from the operation unit 42 or received from the outside by the communication unit 44.
The control unit 41 stores the image data acquired from the examination device 5A in the primary DB 462 of the storage unit 46, and adds a new record to the image information table T4 on the basis of the accessory information (the patient ID, the examination ID, the patient name, the examination date & time, the image type and the like) acquired from the examination device 5A. In addition, with respect to the corresponding examination in the image information table T4, the control unit 41 puts “YES” in the “existence in primary DB”, puts “NO” in the “existence in center DB”, adds a storage location of the image data in the primary DB 462 to the “storage path in center DB”, and leaves the “storage path in center DB” blank.
The control unit 41 controls the communication unit 44 so that the image data stored in the primary DB 462 of the storage unit 46 and the accessory information (the patient ID, the examination ID, the patient name, the examination date & time, the image type, the storage path in primary DB and the like) are transmitted to the data management server 1 so as to be stored in the center DB 162 of the data management server 1. When a notice that the image data is stored in the center DB 162 and a storage location of the image data in the center DB 162 are received by the communication unit 44 from the data management server 1, with respect to the corresponding examination in the image information table T4, the control unit 41 changes the “existence in center DB” to “YES”, and adds the storage location of the image data in the center DB 162 to the “storage path in center DB”.
If a predetermined condition is satisfied, the control unit 41 deletes the image data stored in the primary DB 462 of the storage unit 46 from the primary DB 462. That is, the control unit 41 functions as a delete unit. More specifically, when a predetermined period (for example, one month, three months or the like) elapses from the time the image data is stored in the primary DB 462 of the storage unit 46, the control unit 41 deletes the image data from the primary DB 462. Preferably, as the predetermined period, a period during which image data is normally referred to in the internal system 2A be set. With respect to the examination to which the deleted image data belongs in the image information table T4, the control unit 41 changes the “existence in primary DB” to “NO”, and deletes the storage location of the image data in the primary DB 462 from the “storage path in primary DB”. In addition, the control unit 41 controls the communication unit 44 so that a notice that the image data is deleted from the primary DB 462 is transmitted to the data management server 1.
The control unit 41 searches the primary DB 462 and the center DB 162 for image data, and with respect to image data stored in the primary DB 462, acquires the image data from the primary DB 462, and displays an image on the display unit 43 on the basis of the image data acquired from the primary DB 462, and with respect to image data not stored in the primary DB 462, acquires the image data from the center DB 162, and displays an image on the display unit 43 on the basis of the image data acquired from the center DB 162. That is, the control unit 41 functions as a display control unit.
When an application program 163 newer than the application program 461 already downloaded and stored in the storage unit 46 exists in the data management server 1, the control unit 41 downloads the newer application program 163 from the data management server 1. That is, the control unit 41 functions as a program update unit. More specifically, the control unit 41 compares version information on the already-downloaded application program 461 with the version information on the latest application program 163 existing in the data management server 1, and when the version of the already-downloaded application program 461 is not the latest, controls the communication unit 44 so that an acquirement request for the latest application program 163 is transmitted to the data management server 1 via the communication network N. When the latest application program 163 is received by the communication unit 44 from the data management server 1 via the communication network N, the control unit 41 stores this application program 163 as the application program 461 in the storage unit 46.
The examination device 5A takes an image of a diagnosis target site of a patient, the diagnosis target site being a subject, and performs digital conversion on the taken image so as to generate a medical-use image. Examples of the examination device 5A include CR, CT and MRI.
The internal systems 2B and the like other than the internal system 2A are similar to the internal system 2A, and hence description thereof is omitted. The terminal devices 4B and the like are similar to the terminal 4A, and hence description thereof is omitted by citing
Next, operations of the data management system 100 are described.
First, the control unit 41 acquires the version information on the application program 461 already downloaded and stored in the storage unit 46 (Step S1).
Next, the control unit 41 accesses a predetermined URL (Uniform Resource Locator) of the data management server 1 via the communication network N (Step S2). More specifically, the control unit 41 controls the communication unit 44 so that the predetermined URL is transmitted to the data management server 1.
In the data management server 1, when the communication unit 14 receives the predetermined URL, the control unit 11 reads the version information on the latest application program 163 stored in the storage unit 16, and the communication unit 14 transmits the version information on the latest application program 163 to the terminal device 4A via the communication network N.
In the terminal device 4A, the control unit 41 acquires the version information on the latest application program 163 from the data management server 1 with the communication unit 44 (Step S3).
Then, the control unit 41 determines whether or not the version of the already-downloaded application program 461 is the latest on the basis of the version information on the already-downloaded application program 461 acquired at Step S1 and the version information on the latest application program 163 acquired at Step S3 (Step S4). When determining that the version of the already-downloaded application program 461 is not the latest (Step S4; NO), namely, when determining that an application program 163 newer than the already-downloaded application program 461 exists in the data management server 1, the control unit 41 downloads the latest application program 163 from the data management server 1 (Step S5). More specifically, the control unit 41 controls the communication unit 41 so that an acquirement request for the latest application program 163 is transmitted to the data management server 1 via the communication network N. When the communication unit 44 receives the latest application program 163 from the data management server 1 via the communication network N, the control unit 41 stores this application program 163 as the application program 461 in the storage unit 46.
At Step S4, when determining that the version of the already-downloaded application program 461 is the latest (Step S4; YES), or after Step S5, the control unit 41 starts the application program 461 (Step S6).
Next, the control unit 41 accesses the primary DB 462 of the storage unit 46 and the center DB 162 of the storage unit 16 of the data management server 1 (Step S7). When the access to both the primary DB 462 and the center DB 162 succeeds (Step S8; OK), the control unit 41 displays a login screen on the display unit 43 (Step S9).
On the other hand, when the access to the primary DB 462 or the center DB 162 fails (Step S8; NG), the control unit 41 displays a message that an error occurs on the display unit 43 (Step S10).
Then, the application start time process ends.
First, a user ID and a user PW are inputted to the login screen displayed on the display unit 43 by an operation made with the operation unit 42 (Step S11). The control unit 41 refers to the facility information table T3 contained in the primary DB 462, and permits the use when the inputted user ID and user PW agree with a user ID and a user PW stored in the facility information table T3.
Next, the control unit 41 accesses the primary DB 462 of the storage unit 46 and the center DB 162 of the storage unit 16 of the data management server 1, and displays a list screen on the display unit 43 on the basis of information agreeing with a search condition (Step S12).
Next, a patient is selected on the list screen displayed on the display unit 43 by an operation made with the operation unit 42 (Step S13). For example, on the received patient list screen 431 shown in
Next, the GW 47 acquires image data from the examination device 5A (Step S15), and the control unit 41 stores the image data acquired from the examination device 5A in the primary DB 462 of the storage unit 46 (Step S16). In addition, the GW 47 acquires the accessory information (the patient ID, the examination ID, the patient name, the examination date & time, the image type and the like) from the examination device 5A. Then, the control unit 41 stores the accessory information (the patient ID, the examination ID, the patient name, the examination date & time, the image type and the like) in the image information table T4, and in the image information table T4, puts “YES” in the “existence in primary DB”, puts “NO” in the “existence in center DB”, adds a storage location of the image data in the primary DB 462 to the “storage path in primary DB”, and leaves the “storage path in center DB” blank.
Next, the control unit 41 displays an image on the display unit 43 on the basis of the acquired image data (Step S17). For example, when a CR capture button 61 is pressed on the viewer screen 432 shown in
In addition, when the control unit 41 stores the image data in the primary DB 462, the control unit 41 controls the communication unit 44 so that the image data is transmitted to the data management server 1, whereby a backup of the image data is made in the center DB 162 of the storage unit 16 of the data management server 1 (Step S18). At the time, the accessory information (the patient ID, the examination ID, the patient name, the examination date & time, the image type, the storage path in primary DB and the like) is also transmitted to the data management server 1. Step S18 is realized by always (for example, at intervals of three seconds) comparing the image data stored in the primary DB 462 with the image data stored in the center DB 162, and executing a resident program to start copying data when detecting that new image data is stored in the primary DB 264. When the communication unit 44 receives a notice that the image data is stored in the center DB 162 and a storage location of the image data in the center DB 162 from the data management server 1, with respect to the corresponding examination in the image information table 4, the control unit 41 changes the “existence in center DB” to “YES”, and adds the storage location of the image data in the center DB 162 to the “storage path in center DB”.
After Step S17 or Step S18, the control unit 41 determines whether or not a predetermined period elapses from the time the image data is stored in the primary DB 462 (Step S19). When determining that a predetermined period elapses from the time the image data is stored in the primary DB 462 (Step S19; YES), the control unit 41 deletes the image data from the primary DB 462 (Step S20). Then, with respect to the corresponding examination in the image information table 4, the control unit 41 changes the “existence in primary DB” to “NO”, and deletes the storage location of the image data in the primary DB 462 from the “storage path in primary DB”. In addition, the control unit 41 controls the communication unit 44 so that a notice that the image data is deleted from the primary DB 462 is transmitted to the data management server 1.
Then, the image capture process ends.
First, a user ID and a user PW are inputted to the login screen displayed on the display unit 43 by an operation made with the operation unit 42 so as to log in (Step S21).
Next, the control unit 41 accesses the primary DB 462 of the storage unit 46 and the center DB 162 of the storage unit 16 of the data management server 1, and displays a list screen on the display unit 43 on the basis of information agreeing with a search condition (Step S22).
Next, a patient is selected on the list screen displayed on the display unit 43 by an operation made with the operation unit 42 (Step S23).
Next, the control unit 41 accesses the primary DB 462 of the storage unit 46 and the center DB 162 of the storage unit 16 of the data management server 1 (Step S24). When image data of the selected patient exists in the primary DB 462 or the center DB 162 (Step S25; YES), the control unit 41 determines whether or not the image data of the selected patient exists in the primary DB 462 (Step S26). More specifically, the control unit 41 refers to the column “existence in primary DB” in the image information table T4 contained in the primary DB 462 with respect to each examination performed on the selected patient, and in the case of “YES”, determines that the image data exists in the primary DB 462, and in the case of “NO”, determines that the image data does not exist in the primary DB 462.
When determining that the image data of the selected patient exists in the primary DB 462 (Step S26; YES), the control unit 41 refers to the column “storage path in primary DB” in the image information table T4 with respect to the corresponding examination so as to acquire the image data from the primary DB 462 (Step S27).
On the other hand, when determining that the image data of the selected patient does not exist in the primary DB 462 (Step S26; NO), the control unit 41 refers to the column “storage path in center DB” in the image information table T4 with respect to the corresponding examination so as to acquire the image data from the center DB 162 (Step S28). More specifically, the control unit 41 controls the communication unit 44 so that an acquirement request for the image data specified by the “storage path in center DB” is transmitted to the data management server 1 via the communication network N.
In the data management server 1, the control unit 11 reads the image data specified by and corresponding to the “storage path in center DB” from the center DB 162, and the communication unit 14 transmits the read image data to the terminal device 4A.
In the terminal device 4A, the communication unit 44 receives the image data transmitted from the data management server 1.
After Step S27 or Step S28, when other image data of the selected patient exists (Step S29; YES), the control unit 41 returns to Step S26, and repeats the process for the other image data. At Step S29, when other image data of the selected patient does not exists (Step S29; NO), the control unit 41 displays an image or images on the display unit 43 on the basis of the acquired one or more image data (Step S30).
In the data management server 1, data compression, resolution thinning or the like may be performed on image data in advance so as to generate a compressed image, and when the image data is acquired from the center DB 162 of the terminal device 4A, the compressed image may be acquired and displayed first.
At Step S25, when image data of the selected patient does not exist in either the primary DB 462 or the center DB 162 (Step S25; NO), the process ends there.
Then, the image display process ends.
First, the control unit 11 determines whether or not now is the timing to calculate a fee (Step S31). For example, a certain date of each month is predetermined as a fee calculation day.
When determining that now is the timing to calculate a fee (Step S31; YES), the control unit 11 acquires the number of software used times, the data storage amount and the number of cooperative service used times with respect to a target medical facility from the facility information table T1 contained in the center DB 162 (Step S32). Then, the control unit 11 calculates a fee for use of the data management system 100 by the target medical facility (terminal device 4A, 4B or . . . ) on the basis of the acquired number of software used times, data storage amount and number of cooperative service used times (Step S33). For example, the fee increases as the number of software used times increases, the fee increases as the data storage amount increases, and the fee increases as the number of cooperative service used times increases. However, a calculation method of the fee for use thereof is not limited thereto.
Then, the fee calculation process ends.
As described above, according to the embodiment, in the terminal device 4A, 4B and . . . , the image data stored in the primary DB 462 is acquired from the primary DB 462, and the image data not stored in the primary DB 462 (the image data deleted from the primary DB 462 as a predetermined period elapses) is acquired from the center DB 162. Accordingly, time necessary for displaying images can be reduced, and the diagnostic efficiency can be prevented from decreasing. Usually, image data generated by an examination is referred to right after the examination. Hence, by keeping the image data in the primary DB 462 for a predetermined period, images can be displayed promptly even in a not-high-speed communication environment.
Furthermore, when an application program 163 newer than the already-downloaded application program 461 exists in the data management server 1, the terminal device 4A, 4B and . . . automatically downloads the newer application program 163 from the data management server 1. Accordingly, the latest application program can be used always, and also user's trouble can be reduced.
Furthermore, in the data management server 1, fees can be calculated in accordance with the use of the data management system 100 by the terminal device 4A, 4B and . . . .
The above-described embodiment is an example of the data management system of the present invention, and hence the present invention is not limited thereto. In addition, the detailed configurations and detailed operations of the devices constituting the system can be appropriately modified without departing from the spirit of the present invention.
For example, in the embodiment, in the terminal device 4A, 4B and . . . , image data is deleted from the primary DB 462 when a predetermined period elapses from the time the image data is stored in the primary DB 462. However, image data may be deleted in order of a period stored in the primary DB 462 with the longest one first when the data amount of data stored in the storage unit 46 reaches the storage capacity of the storage unit 46 (or when the data amount in the primary DE 462 reaches a predetermined storage capacity usable as the primary DB 462).
In the above, as a computer readable medium to store the programs to perform the processes, an HDD or a nonvolatile memory is used. However, this is not a limitation. As another computer readable medium, a portable storage medium such as a CD-ROM can be used. Furthermore, as a medium to provide data of the programs via a communication line, a carrier wave can be used.
The information processing device and the data management system of the present invention have applicability in the medical field in which image data acquired from examination devices is managed.
