TECHNICAL FIELD The present invention relates to an X-ray imaging apparatus and a management method for treating an image that fails in X-ray imaging as an unsatisfactory image.

Background Art Conventionally, in X-ray imaging for medical diagnostic purposes, a film screen system combining a sensitizer and an X-ray photographic film has been widely used. The photographing order requested by the doctor returns to the doctor with the X-ray film, and the doctor observes the X-ray film with the X-ray film observation device. In this case, in order to easily observe a diagnostic site | part, it is set so that the density | concentration area | region which can be observed easily will be a contrast range of about 1.0-1.5D. However, if it deviates from photography condition, it will become overexposure or become underexposure. This adversely affects the diagnosis. Therefore, the film photographed satisfactorily is not used for diagnosis. This failed film is discarded as unsatisfactory filmed film.

Recently, in place of this film screen system, an X-ray imaging system for acquiring an image signal from a flexible phosphor accumulating X-ray energy, or a planar detector (FPD) for converting X-rays into an electrical signal proportional to the intensity of X-rays. : Flat Panel Detector) is adopted.

Such an imaging device can solve the problem of the conventional exposure control. In particular, by using the FPD, the user can confirm the image immediately after shooting. Therefore, the user can immediately determine whether shooting was successful immediately after shooting, without waiting for the development of the film or the reading processing of the flexible phosphor, and can quickly retake the shooting order where the shooting was not successfully performed. . Therefore, the burden of waiting time required for an X-ray subject and a radiographer can be greatly reduced.

In addition, when a digital X-ray imaging apparatus is used, outputting an image on a film wastes resources and costs if the captured image is not suitable. Therefore, a medical printer as shown in Japanese Laid-Open Patent Publication No. 2001-175771 and a system which does not transmit unsatisfactory images to a diagnostic image server have been proposed.

In this case, by not transmitting an image taken unsatisfactorily to the image server, the load on the network can be effectively reduced or the capacity of the image server used can be reduced.

However, in the conventional film screen system, the manager such as the chief radiographer or the chief engineer confirms the film photographed unsatisfactorily. Therefore, the administrator can check who is repeating such an error, how many failed shots among the plurality of shot images, and supervise X-ray imaging. In this case, the radiographer will carefully perform the photography under strict guidance.

By digitizing the X-ray imaging apparatus, it is possible to reduce the cost of unsatisfactory film and contribute to hospital management. However, management of an unsatisfactory photographed image is improperly performed, so that the number of unsatisfactory photographed images becomes unclear. Thus, an unsatisfactory image is easily generated. That is, there is a fear that the subject will be exposed without need, and such unnecessary exposure will damage the health of the patient.

This invention is made | formed in view of the said subject, and transmits the image or imaging | photography information unsatisfactorily taken to an X-ray imaging management server apparatus in order to manage the imaging | photography record containing the skill of a radiographer and a photography error. Accordingly, it is an object of the present invention to provide an X-ray imaging apparatus and management method which further improves conventional operation while performing digital imaging.

In order to achieve the above object, according to an aspect of the present invention, an X-ray imaging apparatus including an image management system for manipulating and tracking data correlated with an unsatisfactorily captured image is an image that has not been successfully captured. Photographing error instructing means for marking or flagging the image as satisfactorily photographed, an input means for easily inputting a reason for photographing error, and a transmission means for transmitting an unsatisfactory photographed image and reason for photographing error.

According to another aspect of the present invention, the X-ray image photographing apparatus further includes user management means for identifying an operator that has made a shooting error, and the transmitting means is provided with an unsatisfactory image with the user identification information and the reason for the shooting error. Send. According to another aspect of the present invention, the X-ray image photographing apparatus further includes compression means for compressing an unsatisfactorily captured image instructed to be invalid, and the transmission means transmits the compressed image.

According to another aspect of the present invention, the transmitting means transmits an unsatisfactory image and a photographing error reason at a preset time or period. According to another aspect of the present invention, the transmitting means transmits, to the other server, an unsatisfactory image that is not indicated as invalid and a valid image that is not indicated as invalid.

Further, according to another aspect of the present invention, the X-ray imaging apparatus further includes an X-ray generating apparatus for radiating X-rays, and user management means for identifying an operator who has made a shooting error, and the transmitting means is X-rays. The shooting conditions of the generating device, the user identification information, the unsatisfactory picked-up image, and the shooting error reason are transmitted. In addition, according to another aspect of the present invention, the transmission means uses the Simple Mail Transfer Protocol (SMTP) as the protocol to transmit.

According to another aspect of the present invention, there is provided an image management method performed in an X-ray imaging apparatus including an image management system for manipulating and tracking data correlated with an unsatisfactorily captured image. Here, the method marks or flags an image not successfully captured as an unsatisfactory image, inputs a photographing error reason, and transmits an unsatisfactory photographed image and a photographing error reason.

EMBODIMENT OF THE INVENTION Hereinafter, embodiment of this invention is described in detail using drawing.

BRIEF DESCRIPTION OF THE DRAWINGS It is a block circuit block diagram which shows the system structure of an example of the medical digital X-ray imaging apparatus which concerns on embodiment of this invention. The X-ray imaging apparatus 10 includes an image reading control unit 12, a RAM 13, a CPU 14, a disk interface 15, a LAN interface 16, and a user interface connected to each other via an internal bus 11. (17) is provided. The RAM 13 includes a RAM 13a for storing a control program and a RAM 13b for temporarily storing an image.

The output of the planar detector 18 (FPD) equipped with the phosphor and the large screen photoelectric conversion device is connected to the image reading control unit 12 that stores the image via the data line 10a. The disk interface 15 is connected to a control program and a hard disk 19 for storing correction information necessary for photographing and a photographed image. The display device 20 and an operation unit 21 such as a keyboard and a mouse are connected to the user interface 17. The display device 20 and the operation unit 21 may be replaced with a touch panel.

The output of the exposure switch 22 is connected to the X-ray tube 24 via the X-ray generator control unit 23. The X-ray tube 24 irradiates X-rays to a subject located in front of the FPD 18. In addition, the X-ray generation device control unit 23 is connected to the image reading control unit 12 via the synchronization signal line 10b. The order device 26 is connected to the LAN interface 16 for communication with an external device via a LAN cable 25.

This X-ray imaging apparatus 10 reads a control program from the hard disk 19, and operates the CPU 14 on the RAM 13a. In order to use the X-ray imaging apparatus 10, the radiographer logs in using the operation unit 21. Login management is performed, for example, for the purpose of functional management of the radiographer. For management of the radiographer, it is necessary to specify the error occurrence time, the error generator, and the reason for the error.

2 is a front view of an example login screen for identifying an operator in accordance with aspects of the present invention. In order to prevent the trick of photographing one article as another article, the user name and password are inputted into the user ID input field 31 and the password input field 32 of the login screen 30 of the display device 20 shown in FIG. 2. do.

When the authentication of the user is successful and the login operation is completed, the CPU 14 sends the photographing order information transmitted from the radiology and information system RIS not shown in FIG. 1 from the order device 26 connected to the LAN cable 25. Receive.

3 is a front view of an example screen on which a list of shooting orders acquired by the X-ray imaging apparatus according to the aspect of the present invention is displayed. In the present embodiment, the list of received photographing order information is displayed on the screen 40 of the display device 20 via the user interface 17 as shown in FIG. 3. The radiographer who is an operator of the X-ray imaging apparatus 10 selects the test | inspection item 41 of the screen 40 with a mouse using a pointing device.

4 is a front view of an example screen on which photographing order information received by an X-ray imaging apparatus according to an aspect of the present invention is displayed. Therefore, the control program of the RAM 13a executed by the CPU 14 changes the screen 40 to the screen 50, for example, as shown in Fig. 4, and displays the received shooting order information on the screen 50. ).

The CPU 14 presents the inspection item 41 selected in FIG. 3 to the operator. Thus, during the inspection, for example, a name is displayed in the subject information field 51 of the screen 50. In addition, the screen 50 includes a shooting condition display field 53 for displaying a shooting item for a shooting site displayed in the received shooting site field 52 in the form of a button, and a system of the X-ray imaging apparatus 10. The system status display field 54 displaying the status and the shooting end button 55 are provided.

The CPU 14 executes a system control program. When the operator clicks the "thorax front" button which is the first photographing order information in the photographing site field 52, the CPU 14 sets the "thorax front" button, so that the "thorax front" button is selected. The operator positions the subject S between the FPD 18 and the X-ray tube 24 to adjust the posture (position) of the subject S that is suitable for the photographing region indicated in the photographing region field 52. In the meantime, the CPU 14 executes a control program, performs control of applying a voltage to the FPD 18, and sets the FPD 18 to an X-ray photographic state. When the CPU 14 detects that the FPD 18 is in the X-ray photographable state, a "READY" message is displayed in the system status display field 54.

After checking the screen of the system status display field 54, the operator presses the exposure switch 22 and inputs a trigger for generating X-rays into the system. The generated exposure signal is input to the image reading control part 12 via the X-ray generation device control part 23 and the synchronization signal line 10b. The image reading control part 12 generates the exposure permission signal, after confirming whether the FPD 18 is in a photographable state via the data line 10a. This exposure permission signal is returned to the X-ray generator control unit 23. The X-ray generator control unit 23 causes the X-ray tube 24 to irradiate X-rays.

After irradiation of the X-rays, the X-rays passing through the subject S are acquired as digital data by the FPD 18 via a phosphor not shown in the figure. Then, the digital data is transmitted to the image reading control unit 12. Next, the CPU 14 executes the control program and controls the display device 20 through the user interface 17 so that the screen 60 is displayed on the display device 20 as shown in FIG. 5. do.

5 is a front view of a screen of an example of a display device after shooting according to an aspect of the present invention. The CPU 14 displays the image data acquired from the image reading control section 12 on the image display field 61 of the screen 60, and displays the dose value received from the X-ray generation device control section 23 as the shooting execution information. The display device 20 is controlled to display in the dose value display field 62 so as to store the image data and the photographing execution information in the hard disk 19. In order to change the automatic density adjustment value of the image displayed in the image display field 61, the operator can change the density of the photographed image by adjusting the density adjustment parameter 63. Similarly, by adjusting the contrast adjustment parameter 64, the contrast of the captured image can be changed.

After confirming the picked-up image displayed on the image display field 61 of the screen 60, the operator clicks the next button 65 on the screen to perform the next shooting. In contrast, the CPU 14 executes a program and controls the display device 20 so that the screen 50 shown in FIG. 4 is displayed again on the display device 20. The CPU 14 detects selection of the next order in the photographing site field 52 by the user via the user interface 17. The CPU 14 repeats the above-described shooting flow until all the shooting orders are completed.

When all the orders are completed, the screen 60 is displayed again on the display device 20. Since there is no unrecorded order, the CPU 14 changes the display of the next button 65 to the message display of "inspection". When the operator clicks the "test end" message, the test of the subject S ends.

When the inspection end is instructed, the control program transmits the shooting conditions and the shooting execution information stored in the hard disk 19 to the order device 26. The CPU 14 reports to the order device 26 that shooting has been completed, according to a predetermined communication protocol. At this time, the CPU 14 reports to the ordering device 26 photographing conditions, such as photographing conditions, and photographing execution information such as irradiation dose.

In addition, the picked-up image is image data including incidental information such as the above-mentioned shooting conditions and shooting execution information, and is output to an external device or the like in accordance with a standard communication protocol for medical treatment called DICOM (Digital Imaging Communication in Medicine).

6 is a block circuit configuration diagram for describing an exemplary embodiment according to an aspect of the present invention. For example, as shown in FIG. 6, the X-ray imaging apparatuses 10 'and 10 "include a printer 70, a PACS (Picture Achieving and Communication System), an image viewer apparatus 72, and a photographing management apparatus. The 73 is connected.The external memory device 74 is connected via the PACS 71.

The doctor who issued the photographing order performs diagnosis using the output film or the image displayed on the image viewer device 72. After the diagnosis is confirmed using the image viewer device 72, the doctor creates a diagnosis report. After the diagnostic report is stored in the PACS 71, the PACS 71 stores the image in the external storage device 74 and reports the completion of storage to the X-ray imaging apparatuses 10 'and 10 ". The X-ray imaging apparatuses 10 ', 10 " that have received the message transmit the photographing execution record information to the photographing management apparatus 73.

Although a method of photographing an image has been described in accordance with request information, the purpose of inspection is to acquire an image of a photographing site designated by a doctor. However, shooting may not succeed with one operation. In most cases, photography is not successful due to the blurring of the image of the image due to the movement of the subject S. FIG. As the position adjustment fails, an improper, so-called "unsatisfactory image" is generated that cannot be used for diagnosis.

In this case, the operator retakes an image that fails to capture. In the photographing execution information returning to RIS and the image which the doctor uses for diagnosis, the unsatisfactory image taken before re-photographing is unnecessary. Under the designated photographing conditions, only the image obtained by appropriately photographing the designated portion is necessary. However, even after the imaging, the image may be reproduced until the diagnosis is completed. Therefore, not only the photographed image but also the unsatisfactory image must be stored.

7 is a front view of an exemplary screen when an unsatisfactory image is taken in accordance with aspects of the present invention. For example, the screen 80 of FIG. 7 shows an example in which the photographed image 81 is blurred because the subject S moves when photographing, and re-photographing is required. When the operator determines that reshooting is necessary and selects the reshoot button 82, the CPU 14 executes a control program and a dialog for inputting an invalid reason, that is, a photographing error reason, as shown in FIG. The screen 90 is displayed.

8 is a front view of an example screen for inputting a re-photography or shooting error reason according to an aspect of the present invention. On this screen 90, the article name 91 to log on to the X-ray imaging apparatus is displayed, and at the same time, a selection button 92 for photographing error reason is displayed. After the operator selects the shooting error reason and clicks the OK button 93 to confirm the selection, the dialog screen 90 is closed. The CPU 14 stores the determined data in a memory or a database as shown in Fig. 9, and continues shooting. Then, the CPU 14 controls the display device 20 so that the screen 50 is displayed on the display device 20 as shown in FIG. The CPU 14 sets shooting parameters under the same conditions, and controls the FPD 18 to be in a shooting state.

At this time, the same shooting conditions are usually set. However, it is also possible for the operator to change the condition setting of the shooting condition display field 53 on the screen 50. After that, the operator clicks the exposure switch 22 to retake the image. Then, the rephotographed image is displayed as shown in FIG.

9 is an explanatory view of a storage example of a recording record according to an aspect of the present invention. After re-shooting is displayed as shown in Fig. 5, the shooting record information 100 is stored in the memory as shown in Fig. 9.

After shooting is performed, when the operator clicks the shooting error button 83 instead of the re-shooting button 82 (see FIG. 7), the CPU 14 controls the display device 20, as shown in FIG. 8. The dialog screen 90 is displayed as well, and the operator is urged to input a photographing error reason.

After all the shooting orders have been completed, when the operator sends an invalid image from the X-ray imaging apparatuses 10 'and 10 "to the external device, the film is wasted and the mass storage device 74 connected to the PACS 71 is lost. This interferes with the image diagnosis performed by the doctor, so that only a valid image is transmitted to the preset printer 70 or the PACS 71, so that the doctor who has taken the photographing order has only the data necessary for the diagnosis. It is possible to build a suitable system.

However, in the above-described configuration, the reason why the unsatisfactory image and the shooting error occurred remains in the X-ray imaging apparatus 10. Therefore, the fact that the rephotographing or the photographing error occurs is not transmitted to the manager of the radiographer. Further, even though the subject S is irradiated with X-rays, the images which are not transmitted to the PACS 71 which is the first server means are in the oldest order when the hard disk 19 of the X-ray imaging apparatus 10 is filled. Erased. That is, unless the manager operates the plural X-ray imaging apparatus 10 to confirm the unsatisfactory image, the unsatisfactory image is automatically deleted after a predetermined time has elapsed.

Therefore, in the present embodiment, the control program 20 executed by the CPU 14 of the X-ray imaging apparatus 10 is # 1 and # 3 shown in FIG. 9 in the PACS 71 which is the first server means for diagnosis. Transmits the image. On the other hand, an unsatisfactory image of # 2 is transmitted to the X-ray imaging management apparatus 73 which is the second server means for shooting recording, together with the shooting information of the # 1, # 2, and # 3 images.

If the shooting management device 73 which is the second shooting management server means configures all the shooting, that is, the successful shooting for the inspection request and all the shooting records of the failed shooting in which the shooting error is generated, from the client device, the X-ray You can create a recording record. In addition, since an unsatisfactory image is also received at the same time, it is possible to achieve the consistency of the shooting error reason by comparing the shooting error reason with an unsatisfactory image. When such a photographing record is recorded in a database and the analysis of each radiographer is performed, the manager can confirm the radiographer's skill as an operator of the X-ray imaging apparatus 10.

The X-ray imaging apparatus 10 'can transmit the imaging error information at the end of the inspection or at a predetermined time when sending the captured image to the external apparatus. On the other hand, the X-ray imaging apparatus 10 'transmits photographing error information at the time when the X-ray imaging apparatus 10' receives the report in which the storage of the printer 70 or the PACS 71 is completed, or on a daily basis. Alternatively, the associated imaging error information may be transmitted in consideration of the accounting information of the hospital. In addition, in some cases, the reason why the image processing is not performed properly is to resend the corrected photographing data from the X-ray photographing apparatus 10 'to the external device, and use the retransmitted photographing data for diagnosis. In this case, however, it is natural that the photographing error information is not resent to the photographing management device 73 which is the second server means.

On the other hand, the number of retransmissions can also be managed. Even when the operator of the X-ray imaging apparatus 10 performs an operation deviating from the general workflow, the operation is tracked and transmitted to the imaging management apparatus 73. As a result, the manager can check the unsatisfactory image and the reason for the photographing error generated by the X-ray photographing apparatus 10 ', 10 "by operating the terminal on the photographing management apparatus 73. FIG.

The system of the aspect of this embodiment manages X-ray imaging record. Therefore, between the X-ray imaging apparatus 10 'and the imaging management apparatus 73, only all the imaging records including imaging errors can be transmitted. In addition, when an unsatisfactory image is received, the image may include a captured image. However, since the administrator does not necessarily need the detailed original image, the system can receive a processed image such as a reduced image or irreversible compression created from the original image and configure the system so that the administrator can confirm whether the reason for the shooting error is appropriate. have.

In addition, since the confirmed image can be automatically deleted, the image protection flag attached to the confirmed image is deleted. The photographing record received for each inspection is stored as a database of a computer which is a server apparatus. Therefore, the X-ray imaging management system can be constructed to take statistics for each radiographer or to take statistics for each imaging error reason. By the above control, the objective of managing the skill of a radiographer can fully be achieved, reducing the load of a server apparatus.

10 is a flowchart of an example of a control program executed by the X-ray imaging apparatus. After the start of the inspection, the control program acquires a photography order in step S1. Next, in step S2, a photographing process is performed. In step S3, it is checked whether all photography orders have been completed. In step S3, when all the photographing orders are not finished (NO in step S3), the process returns to step S2 to execute the photographing process. If all shooting orders are completed in step S3 (YES in step S3), the process proceeds to step S4. In step S4, only the valid inspection image is output to the PACS 71 which is the first server means. The captured image is transmitted using the DICOM protocol, which is a communication standard of a medical device.

Then, in step S5, some or all of the shooting records are output to the shooting management device 73 which is the second server means. The photographing record can be transmitted, for example, as photographing execution information based on DICOM. However, in the present embodiment, the photographing execution information is transmitted using the SMTP (Simple Mail Transfer Protocol) used when transmitting the e-mail. To prevent eavesdropping or spoofing of this protocol, it is desirable to use encrypted Secure Multipurpose Mail Exchange (S / MIME).

In addition, control is performed to output an unsatisfactory image of an unsatisfactory image, for example, by compressing the JPEG image with the photographing record. When the above step processing ends, the program processing relating to the inspection request ends. Then, the process ends in step S6 and waits for execution of the subsequent shooting order.

FIG. 11 is a flowchart of an example of photographing processing in step S2 of FIG. 10. In step S11, a photography process is started. In step S12, the "shooting" button of the shooting order is displayed. In step S13, the parameter corresponding to a photography order is read out from a database. In step S14, the FPD 18 serving as the sensor is set to the "READY" state, and the "READY" state is maintained until X-ray imaging is performed in step S15. If photography is executed, image analysis is executed in step S16. Next, an image is displayed on the display device 20 in step S17.

When the operator changes the image processing parameters while viewing the image, an image processing parameter adjustment screen is displayed. After the operator changes the image processing parameters, the operator determines the changed parameters. In the case where the image processing parameters are not changed, the result of determining whether the photographed image can be used for diagnosis is input to step S18. If the input is a "next" button in step S19 (YES in step S19), the shooting record data is updated to perform the next shooting in step S20. Next, the imaging process ends in step S21.

When the judgment of step S19 is that the "next" button is not selected (NO in step S22), it is determined whether the "error" button is selected in step S22. If the "error" button is selected in step S22 (YES in step S23), the shooting error reason is input as described above, and in step S23 the shooting record is recorded as the shooting error. Next, the imaging process ends in step S21.

If the "error" button is not selected in step S22 (NO in step S22), it is determined whether the "reshoot" button is selected in step S24. If the "reshoot" button is selected in step S24 (YES in step S24), the processing proceeds to step S25. In step S25, in order to add and display a shooting error mark indicating that the image is an invalid image and need to be retaken, the reason for reshooting is input as described above, and the shooting record data is updated. The process then returns to step S13 to execute the X-ray imaging waiting process. In step S24, if the "re-shooting" button is not selected (NO in step S24), the process returns to step S18 to execute the determination of the shooting result again.

In this embodiment, the case where the control program is stored in the hard disk 19, transferred to the RAM 13, and executed by the CPU 14 has been described. However, execution of the control program need not be limited to this case. The control program may be implemented using any storage medium. In addition, the control program can be realized by using a circuit that performs similar operations.

In addition, this embodiment is applicable to the system which consists of a some apparatus, or is applicable to the apparatus which consists of one apparatus. For example, the above-described embodiment is also achieved by supplying a recording medium on which program code of software for realizing the functions of the above-described embodiments is supplied to a system or apparatus, and reading out and executing the program code stored in the computer or CPU. can do. In this case, the program code itself read out from the recording medium realizes the functions of the above-described embodiments, and the recording medium on which the program code is recorded constitutes the present invention.

As a recording medium for supplying the program code, for example, a floppy disk, hard disk, optical disk, magneto-optical disk, CD-ROM, CD-R, magnetic tape, nonvolatile memory card, ROM, or the like can be used.

In addition, by executing the program code read by the computer, not only the functions of the above-described embodiments are realized, but also the OS or the like running on the computer can perform some or all of the actual processing based on the instruction of the program code. It may be.

The program code read from the recording medium is recorded and used in a memory provided in a function expansion board or a function expansion unit connected to a computer. The function of the above-described embodiment may be realized by the CPU or the like provided in the function expansion board or the function expansion unit performing part or all of the actual processing based on the instruction of the program code.

In addition, the program can be transmitted to the requestor from the storage medium on which the program code of the software for realizing the functions of the above-described embodiments is transmitted via a communication line such as the Internet.

In the above-described embodiment, a plurality of examples of operators of the X-ray imaging apparatus are posted, and a user name and a password are inputted for identification. However, by adopting biometrics such as fingerprints and irises, a system with high safety and operability can be constructed. In addition, when using an X-ray imaging apparatus, an operator may authenticate using the thing which added the barcode and IC tag to the nameplate used in a hospital. In a given case, the operator of the X-ray imaging apparatus is identified, and the photographing record is transmitted to the management apparatus.

In addition, since the X-ray imaging management server means is a program executed by the CPU 14, it is not always necessary to execute it on the imaging management apparatus 73. For example, the X-ray imaging management server means can be configured inside the X-ray imaging apparatus 10 '. In this case, the X-ray imaging management function can be realized when the manager uses the X-ray imaging apparatus 10 '.

In addition, when there is only one operator of the X-ray imaging apparatus in a small hospital or the like, there is no need to identify the operator, so that a login step is unnecessary. Therefore, display of the login screen shown in FIG. 2 can be abbreviate | omitted using predetermined user name. In this case, the X-ray imaging management server means can be configured inside the X-ray imaging apparatus, and the X-ray imaging management function can be executed by the X-ray imaging apparatus alone.

This invention is not limited to the above embodiment. Various modifications and variations can be made within the scope of the present subject matter.

As described above, according to the X-ray image photographing apparatus, the management system, and the management method according to the embodiment of the present invention, the manager records an unsatisfactory record of an undelivered photographing error for diagnosis and an image taken satisfactorily from the client device. The photographing management server apparatus operated by the receiver receives. Thus, an X-ray imaging management system capable of referring to a digitally unsatisfactory photographed image can be realized instead of the conventionally unsatisfactory photographed film. In addition, since an X-ray imaging management system capable of taking statistics of imaging errors for each radiographer can be realized, it can contribute to hospital management from the standpoint of patient protection.

Although the present invention has been described with reference to exemplary embodiments, the present invention is not limited to the exemplary embodiments.
