Description

Technical Field

[0001] The embodiments disclosed in this specification and the drawings relate to a medical information processing apparatus.

[0002] Conventionally, there has been known an image diagnostic apparatus that irradiates a patient such as a patient with X-rays and captures X-ray image data of the patient using the X-rays that have passed through the patient. In addition, there has been known a technique for warning when there is a possibility that the radiation dose of the patient by the image diagnostic apparatus exceeds an allowable threshold value.

[0003] However, even when the threshold value is exceeded, there may be a case where the patient should be imaged by the image diagnostic apparatus. However, it has been troublesome to collect materials for determining whether the benefit of the patient from this imaging exceeds the loss.

Summary of the Invention

Problems to be Solved by the Invention

[0005] One of the problems to be solved by the embodiments disclosed in this specification and the drawings is to provide information for determining whether the benefit of the patient from imaging exceeds the loss. However, the problems to be solved by the embodiments disclosed in this specification and the drawings are not limited to the above problems. The problems corresponding to the respective effects of each configuration shown in the embodiments described later can also be regarded as other problems.

Means for Solving the Problems

[0006] The medical information processing apparatus according to the embodiment includes an input unit and an acquisition unit, A prediction unit, It includes a display control unit and an input unit. The input unit receives an input of patient identification information for identifying a patient to be examined as an examination order for requesting acquisition of X-ray image data by an image diagnostic apparatus. The acquisition unit acquires a record of the dose of radiation exposure for each type of the image diagnostic apparatus associated with the acquisition of X-ray image data regarding the patient identified by the patient identification information. Based on the inspection order received by the input unit, the prediction unit predicts a predicted value of the patient's exposure dose. When the examination order is received by the input unit, the display control unit causes a summary screen indicating the dose of radiation exposure by each of the image diagnostic apparatuses for each part of the patient to be displayed based on the record of the dose of radiation exposure. Then, when the sum of the cumulative value of the exposure dose acquired by the acquisition unit and the predicted value is equal to or greater than a threshold value, the display control unit displays an alternative item to be implemented instead of acquiring the X-ray image data received by the input unit, based on the accounting calculation conditions when the alternative item is implemented.

Embodiments for Carrying Out the Invention

[0008] Hereinafter, a medical information processing apparatus according to the present embodiment will be described with reference to the drawings. In the following embodiments, parts denoted by the same reference numerals perform the same operations, and redundant descriptions will be omitted as appropriate.

[0009] FIG. 1 is a block diagram showing an example of the configuration of an information providing system 1 according to the present embodiment. The information providing system 1 includes a plurality of modalities 10, a PACS (Picture Archiving and Communication Systems) 20, a HIS (Hospital Information System) 30, a RIS (Radiology Information Systems) 40, and an operation terminal 50. Also, each system and each device are communicably connected to each other via a network. Note that the configuration shown in FIG. 1 is an example, and the number of each system and each device may be arbitrarily changed. Also, a device not shown in FIG. 1 may be connected to the network. That is, although the information providing system 1 shown in FIG. 1 includes four modalities 10, the number of modalities 10 may be five or more, or less than four.

[0010] Each modality 10 is an image diagnostic apparatus that irradiates a patient such as a patient with X-rays and captures X-ray image data of the patient using the X-rays that have passed through the patient. For example, the modality 10 is an X-ray CT (Computed Tomography) apparatus, an X-ray TV apparatus, an X-ray diagnostic apparatus, a mammography apparatus, or the like. Also, the four modalities 10 shown in FIG. 1 may be different types of image diagnostic apparatuses, or all or part of them may be the same type of image diagnostic apparatus. Then, the modality 10 transmits the X-ray image data generated by the imaging to the PACS 20.

[0011] The PACS 20 is a server apparatus that stores image data such as X-ray image data generated by the modality 10. For example, the PACS 20 is realized by computer devices such as a server and a workstation.

[0012] HIS30 manages various types of information related to patients, such as patients. For example, HIS30 is realized by computer devices such as servers and workstations. More specifically, HIS30 stores electronic medical record information 31, alert master 32, radiation master 33, alternative item master 34, and examination order information 35 in the storage circuit of its own device. The electronic medical record information 31 is data having a patient's medical record. The alert master 32 is data having a condition for alerting that the exposure dose is equal to or higher than a threshold value. The radiation master 33 is data used for predicting the exposure dose. The alternative item master 34 is data having items that can be used as alternatives to the imaging requested by the examination order. The examination order information 35 is information for requesting imaging of a patient by modality 10.

[0013] RIS40 manages various types of information related to the radiology department. For example, RIS40 is realized by computer devices such as servers and workstations. More specifically, RIS40 stores exposure dose record information 41 in the storage circuit of its own device. The exposure dose record information 41 is information related to the recording of a patient's exposure dose accompanying the acquisition of X-ray image data by modality 10.

[0014] The operation terminal 50 is a terminal operated by medical staff such as doctors. The operation terminal 50 is realized by computer devices such as personal computers and tablet terminals. For example, the operation terminal 50 is a device that receives the input of an examination order for an imaging device by accessing HIS30.

[0015] In such an information providing system 1, when it is determined that imaging by the imaging diagnostic apparatus is necessary, the medical staff inputs an examination order for requesting acquisition of the patient's X-ray image data into the operation terminal 50. The operation terminal 50 acquires a predicted value of the patient's exposure dose based on the examination order and the radiation master 33. Further, the operation terminal 50 determines whether or not the total value of the cumulative value obtained by summing up the exposure doses of the patient included in the exposure dose recording information 41 and the predicted value of the exposure dose is equal to or greater than a threshold value. When the value is less than the threshold value, the operation terminal 50 issues examination order information 35. On the other hand, when the value is equal to or greater than the threshold value, the operation terminal 50 notifies that the patient's exposure dose is equal to or greater than the threshold value.

[0016] Specifically, the operation terminal 50 displays a summary screen 100 (see FIG. 8) showing a summary of the patient's exposure dose and an alternative item screen 200 (see FIG. 9) proposing to perform in place of the examination order. Then, the operation terminal 50 accepts an input as to whether or not to perform imaging by the imaging diagnostic apparatus. That is, the operation terminal 50 accepts an input as to whether or not to acquire the patient's X-ray image data.

[0017] In this way, when the summary screen 100 is displayed, the medical staff can grasp the patient's past exposure dose. Therefore, the medical staff can determine whether or not to acquire the X-ray image data while considering the influence on the patient in the exposure. In addition, when the alternative item screen 200 is displayed, the medical staff can consider examining the patient by a method different from imaging by the imaging diagnostic apparatus.

[0018] Next, the data configurations of various data will be described.

[0019] FIG. 2 is a diagram showing an example of the data configuration of the electronic medical record information 31. The electronic medical record information 31 has a patient code, attribute information, and medical record information associated therewith. The patient code is identification information for identifying a patient such as a patient. The attribute information is information indicating the attributes of the patient. Specifically, the attribute information is information such as the patient's gender and age. The medical record information is information indicating the record of the patient's medical treatment.

[0020] FIG. 3 is a diagram showing an example of the data configuration of the alert master 32. In the alert master 32, an alert item name, alert condition information, and a threshold value are associated. The alert item name is the name of the alert. The alert condition information is information for specifying the target of the alert. In the alert condition information, the patient's part is associated for each piece of patient attribute information. Then, when the attribute information and the part match, the operation terminal 50 determines that it is the target of the alert. The threshold value is information indicating the exposure dose that serves as a criterion for determining whether to issue an alert. For example, in the alert master 32, it is set to issue an alert when the exposure dose of the chest of a 30-year-old woman is equal to or higher than the threshold value.

[0021] FIG. 4 is a diagram showing an example of the data configuration of the radiation master 33. In the radiation master 33, a modality type code, a imaging method, a part, and a standard exposure dose are associated. The modality type code is identification information for specifying the type of the modality 10. The imaging method is the imaging method in the modality 10 specified by the modality type code. The part is information indicating the patient's part. The standard exposure dose is the standard exposure dose to which the patient is exposed when imaging is performed by the imaging diagnostic apparatus for the associated content. That is, the standard exposure dose is a predicted value of the patient's exposure dose when imaging is performed by the imaging diagnostic apparatus.

[0022] FIG. 5 is a diagram showing an example of the data configuration of the alternative item master 34. In the alternative item master 34, examination content information, alternative items, and accounting information are associated. The examination content information is information indicating the content of the examination order that is the target of the alternative. For example, the examination content information includes a modality type code, an imaging method, the patient's part, and the like. The alternative item is information indicating the examination content proposed to be implemented instead. The accounting information is information regarding the accounting for the examination of the alternative item. For example, the accounting information is information such as the calculation conditions of the medical fee reduction after the second time in the same month and the profit amount obtained by performing the examination of the alternative item.

[0023] FIG. 6 is a diagram showing an example of the data configuration of the exposure dose recording information 41. The exposure dose recording information 41 is associated with patient data and examination history information. The patient code is identification information for identifying a patient. The examination history information is information in which the examination date and time, a modality type code indicating the type of the modality 10 that performed the examination, the exposed part of the patient, and the exposure dose of the patient are associated with each other.

[0024] Note that the arrangement of the various data shown in FIG. 1 is an example, and the arrangement of the various data may be arbitrarily changed, or there may be a device or system not shown in FIG. 1.

[0025] Next, the configuration of the operation terminal 50 according to the present embodiment will be described.

[0026] FIG. 7 is a block diagram showing an example of the configuration of the operation terminal 50 according to the present embodiment. The operation terminal 50 includes a communication interface 51, an input interface 52, a display 53, a memory circuit 54, and a processing circuit 55.

[0027] The communication interface 51 is connected to the processing circuit 55 and controls various data transmissions and communications performed between the processing circuit 55 and each device connected via a network. For example, the communication interface 51 is realized by a network card, a network adapter, a NIC (Network Interface Controller), or the like.

[0028] The input interface 52 is connected to the processing circuit 55, converts the input operation received from the operator (medical staff) into an electrical signal, and outputs it to the processing circuit 55. Specifically, the input interface 52 converts the input operation received from the operator into an electrical signal and outputs it to the processing circuit 55. For example, the input interface 52 is realized by a trackball, a switch button, a mouse, a keyboard, a touch pad that performs an input operation by touching the operation surface, a touch screen in which a display screen and a touch pad are integrated, a non-contact input circuit using an optical sensor, a voice input circuit, and the like. Note that in this specification, the input interface 52 is not limited to only those provided with physical operation components such as a mouse and a keyboard. For example, an electrical signal processing circuit that receives an electrical signal corresponding to an input operation from an external input device provided separately from the apparatus and outputs this electrical signal to the control circuit is also included in the example of the input interface 52.

[0029] The display 53 is connected to the processing circuit 55 and displays various information and various image data output from the processing circuit 55. For example, the display 53 is realized by a liquid crystal display, a CRT (Cathode Ray Tube) display, an organic EL display, a plasma display, a touch panel, or the like.

[0030] The storage circuit 54 is connected to the processing circuit 55 and stores various data. Further, the storage circuit 54 stores various programs for realizing various functions by being read and executed by the processing circuit 55. For example, the storage circuit 54 is realized by a semiconductor memory element such as a RAM (Random Access Memory), a flash memory, a hard disk, an optical disk, or the like.

[0031] The processing circuit 55 controls the operation of the entire operation terminal 50. The processing circuit 55 has, for example, an inspection order input function 551, a data acquisition function 552, an exposure dose prediction function 553, a notification determination function 554, a display control function 555, an inspection order issuance function 556, and a threshold setting function 557. In the embodiment, each processing function performed by the constituent elements, namely, the inspection order input function 551, the data acquisition function 552, the exposure dose prediction function 553, the notification determination function 554, the display control function 555, the inspection order issuance function 556, and the threshold setting function 557, is stored in the storage circuit 54 in the form of a program executable by a computer. The processing circuit 55 is a processor that reads out and executes the program from the storage circuit 54 to realize the functions corresponding to the respective programs. In other words, the processing circuit 55 in the state of having read out each program will have each function shown in the processing circuit 55 of FIG. 7.

[0032] In FIG. 7, it has been described that the inspection order input function 551, the data acquisition function 552, the exposure dose prediction function 553, the notification determination function 554, the display control function 555, the inspection order issuance function 556, and the threshold setting function 557 are realized by a single processor. However, it is also possible to configure the processing circuit 55 by combining a plurality of independent processors, and each processor realizes the functions by executing the program. Further, in FIG. 7, it has been described that a single storage circuit such as the storage circuit 54 stores the programs corresponding to the respective processing functions. However, a plurality of storage circuits may be distributed and arranged, and the processing circuit 55 may be configured to read out the corresponding program from an individual storage circuit.

[0033] The term "processor" used in the above description means, for example, a CPU (Central Processing Unit), a GPU (Graphical Processing Unit), or a circuit such as an application specific integrated circuit (ASIC), a programmable logic device (e.g., a simple programmable logic device (SPLD), a complex programmable logic device (CPLD), and a field programmable gate array (FPGA)). The processor realizes its functions by reading and executing the program stored in the storage circuit 54. Note that instead of storing the program in the storage circuit 54, the program may be directly incorporated into the circuit of the processor. In this case, the processor realizes its functions by reading and executing the program incorporated into the circuit.

[0034] The inspection order input function 551 receives the input of an inspection order. The inspection order input function 551 is an example of an input unit. More specifically, the inspection order input function 551 receives the input of patient identification information for identifying a patient to be inspected as an inspection order for requesting the acquisition of X-ray image data by the image diagnostic apparatus. Here, the patient identification information may be a patient code, the name of the patient, the patient's personal number, or other information.

[0035] Also, the inspection order input function 551 receives the input of an inspection order for requesting the acquisition of X-ray image data of a patient. For example, the inspection order input function 551 receives inputs such as the modality 10 for taking X-ray image data, the imaging method for causing the modality 10 to perform imaging, and the part of the patient to be imaged by the modality 10.

[0036] In addition, when the inspection order input function 551 is notified that the patient's exposure dose has reached or exceeded the threshold value, it accepts an input on whether to request imaging by the imaging diagnostic apparatus. That is, the inspection order input function 551 accepts an input on whether to acquire X-ray image data. Further, even when notified that the exposure dose has reached or exceeded the threshold value, if the inspection order input function 551 performs imaging by the imaging diagnostic apparatus, it accepts an input on the reason for acquiring the X-ray image data. By inputting the reason in this way, it becomes possible to later confirm whether the acquisition of the X-ray image data was appropriate.

[0037] The data acquisition function 552 acquires various types of information from the HIS 30 and the RIS 40. The data acquisition function 552 is an example of an acquisition unit. More specifically, the data acquisition function 552 acquires the electronic medical record information 31, the alert master 32, and the radiation master 33 from the HIS 30. Also, the data acquisition function 552 acquires the exposure dose record information 41 from the RIS 40. That is, the data acquisition function 552 acquires the record of the exposure dose associated with the acquisition of X-ray image data regarding the patient specified by the patient code.

[0038] The exposure dose prediction function 553 predicts a predicted value of the patient's exposure dose based on the inspection order accepted by the inspection order input function 551. The exposure dose prediction function 553 is an example of a prediction unit.

[0039] More specifically, the exposure dose prediction function 553 predicts the patient's exposure dose based on the inspection order accepted by the inspection order input function 551 and the radiation master 33 acquired by the data acquisition function 552. That is, the exposure dose prediction function 553 extracts the attribute information, imaging method, and standard exposure dose associated with the site of the patient included in the inspection order and the attribute information, imaging method, and site of the radiation master 33 that match. Then, the exposure dose prediction function 553 acquires the extracted standard exposure dose as the predicted value of the patient's exposure dose.

[0040] The notification determination function 554 determines whether to notify that the patient's exposure dose is equal to or higher than the threshold value. More specifically, the notification determination function 554 extracts from the alert master 32 the threshold value associated with the attribute information and site of the patient included in the examination order and the attribute information and site of the alert condition information that matches. Further, the notification determination function 554 calculates the cumulative value of the exposure dose of the site to be examined indicated in the examination order. That is, the notification determination function 554 calculates the cumulative value by summing up the exposure doses of the site to be examined within the set period in the examination history information included in the exposure dose record information 41. Here, the set period may be a period set based on a period defined by a country, an institution, an organization, etc., or may be a period arbitrarily set by a hospital or the like.

[0041] Then, when the total value of the predicted value predicted by the exposure dose prediction function 553 and the cumulative value is equal to or higher than the threshold value, the notification determination function 554 determines to notify. On the other hand, when the total value of the predicted value predicted by the exposure dose prediction function 553 and the calculated cumulative value is less than the threshold value, the notification determination function 554 determines not to notify. Note that even when the total value is less than the threshold value, the notification determination function 554 may determine to notify that the total value is close to the threshold value when the total value is close to the threshold value.

[0042] The display control function 555 causes the display 53 to display various screens. The display control function 555 is an example of a display control unit. For example, when the total of the cumulative value of the exposure dose included in the exposure dose record information 41 acquired by the data acquisition function 552 and the predicted value of the exposure dose predicted by the exposure dose prediction function 553 is equal to or higher than the threshold value, the summary screen 100 (see FIG. 8) and the alternative item screen 200 (see FIG. 9) are displayed. Note that the display control function 555 is not limited to both the summary screen 100 and the alternative item screen 200, and either one may be displayed. In this case, when the display control function 555 receives an operation such as pressing a button, the other screen is displayed. Alternatively, the display control function 555 may display the contents of the summary screen 100 and the alternative item screen 200 on one screen.

[0043] FIG. 8 is an explanatory diagram showing an example of the summary screen 100. The summary screen 100 is a screen that aggregates the records of the patient's exposure dose. When an examination order is received by the examination order input function 551, the display control function 555 displays the summary screen 100 that aggregates the records of the patient's exposure dose based on the exposure dose record information 41 indicating the record of the exposure dose. More specifically, the summary screen 100 includes a patient display area 110, a time-series display area 120, a switching tag display area 130, a first dose display area 140, a second dose display area 150, a site-specific exposure dose display area 160, and a human body model display area 170.

[0044] The patient display area 110 is an area where information about the patient who is the subject of imaging by the imaging diagnostic apparatus is displayed. The display control function 555 is an area where the attribute information included in the electronic medical record information 31 is displayed. For example, the patient code, gender, age, etc. are displayed in the patient display area 110.

[0045] The time-series display area 120 is an area where the history of acquisition of the patient's X-ray image data is arranged and displayed in time series. The display control function 555 arranges and displays the examination history information of the exposure dose record information 41 in time series. Further, the display control function 555 displays in a distinguishable manner which type of modality 10 the X-ray image data was acquired by.

[0046] The switching tag display area 130 is an area that displays an after-examination tag button 131 for displaying a summary of the exposure dose after acquiring the X-ray image data and a before-examination tag button 132 for displaying a summary of the exposure dose before acquiring the X-ray image data. That is, in the switching tag display area 130, the after-examination tag button 131 is a button that displays a summary of the predicted value of the exposure dose when the X-ray image data is acquired and the cumulative value of the exposure dose up to the current time. On the other hand, the before-examination tag button 132 is a button that displays a summary of the cumulative value of the exposure dose up to the current time.

[0047] When the post - implementation tag button 131 is pressed, the display control function 555 displays a screen including the sum of the cumulative value of the inspection history information included in the exposure dose record information 41 acquired by the data acquisition function 552 and the predicted value predicted by the exposure dose prediction function 553. Specifically, the display control function 555, based on the inspection order information 35, the predicted value of the exposure dose predicted based on the inspection order information 35, and the inspection history information of the exposure dose record information 41, displays the first dose display area 140, the second dose display area 150, the site - specific exposure dose display area 160, and the human body model display area 170.

[0048] When the pre - implementation tag button 132 is pressed, the display control function 555 displays a screen including the cumulative value of the inspection history information included in the exposure dose record information 41 acquired by the data acquisition function 552. Specifically, the display control function 555, based on the inspection history information of the exposure dose record information 41, displays the first dose display area 140, the second dose display area 150, the site - specific exposure dose display area 160, and the human body model display area 170.

[0049] As described above, the summary screen 100 shown in FIG. 8 enables the comparison of the summaries when X - ray image data is acquired and when X - ray image data is not acquired, by means of the post - implementation tag button 131 and the pre - implementation tag button 132. However, the method of enabling the comparison of the summaries when X - ray image data is acquired and when X - ray image data is not acquired is not limited to this. The summaries when X - ray image data is acquired and when X - ray image data is not acquired may be displayed on separate screens, or may be arranged and displayed on one screen.

[0050] The first dose display area 140 is an area for displaying the exposure dose by each modality 10 in a pie chart. The second dose display area 150 is an area for displaying the exposure dose by each modality 10 in the column of each modality 10. Further, in the second dose display area 150, when the exposure dose of the modality 10 is close to the threshold value, an alert mark 151 indicating that it is close to the threshold value is added. The exposure dose display area 160 by part is an area for displaying the exposure dose by each modality 10 for each part of the patient. The human body model display area 170 is an area for displaying a human body model showing each part exposed by the imaging diagnostic apparatus.

[0051] That is, when the post - implementation tag button 131 is pressed, the display control function 555 causes the cumulative value of the exposure dose to be displayed as the exposure dose in the first dose display area 140, the second dose display area 150, and the exposure dose display area 160 by part. When the pre - implementation tag button 132 is pressed, the display control function 555 causes the sum of the cumulative value of the exposure dose and the predicted value of the exposure dose to be displayed as the exposure dose in the first dose display area 140, the second dose display area 150, and the exposure dose display area 160 by part.

[0052] FIG. 9 is an explanatory diagram showing an example of the alternative item screen 200. The alternative item screen 200 is a screen showing alternative items proposed to be implemented instead of acquiring X - ray image data indicated by the examination order. More specifically, the alternative item screen 200 includes a message display area 210, an alternative item display area 220, a yes button 230, and a no button 240.

[0053] The message display area 210 is an area for displaying a message indicating that the exposure dose of the patient exceeds the threshold value and that there are alternative items. The alternative item display area 220 is an area for displaying alternative items.

[0054] The display control function 555 arranges and displays alternative items in the alternative item display area 220 based on the alternative item master 34. Specifically, the display control function 555 extracts alternative items and accounting information associated with the inspection content information that matches the input content of the inspection order from the alternative item master 34. Then, the display control function 555 displays the alternative items based on the accounting calculation conditions when the alternative items indicated by the accounting information are implemented. For example, the display control function 555 arranges and displays the alternative items in the order of decreasing reduction rate according to the medical record information and accounting information of the electronic medical record information 31. That is, the display control function 555 preferentially displays alternative items that contribute to the operation of the facility.

[0055] The no button 240 is a button that accepts an operation to cancel the acquisition of X-ray image data of the inspection order received by the inspection order input function 551. The yes button 230 is a button that accepts an operation to implement the acquisition of X-ray image data of the inspection order received by the inspection order input function 551. When the yes button 230 is pressed, the display control function 555 displays a reason input screen for accepting the reason for acquiring the X-ray image data. That is, the display control function 555 displays a reason input screen for inputting the reason for acquiring the patient's X-ray image data on the condition that the operation of acquiring the patient's X-ray image data has been accepted when the sum of the cumulative value of the exposure dose and the predicted value of the exposure dose is equal to or greater than the threshold value. Then, the display control function 555 associates and stores the reason input on the reason input screen with the inspection order. Thereby, the reason for acquiring the X-ray image data can be confirmed later.

[0056] When the yes button 230 of the alternative item screen 200 is pressed, the inspection order issuing function 556 issues inspection order information 35 based on the inspection order received by the inspection order input function 551. That is, the inspection order issuing function 556 transmits the inspection order information 35 indicating the inspection order to the RIS 40.

[0057] The threshold setting function 557 sets the thresholds of the alert master 32. The threshold setting function 557 is an example of a setting unit. For example, the threshold setting function 557 sets thresholds for each part of the patient. Also, the threshold setting function 557 sets thresholds for each attribute of the patient.

[0058] Next, the information providing process executed by the information providing system 1 will be described. FIG. 10 is a flowchart showing an example of the information providing process executed by the operation terminal 50 according to the present embodiment.

[0059] The examination order input function 551 of the operation terminal 50 receives an input of a patient code for identifying a patient to be imaged by the imaging diagnostic apparatus (step S1).

[0060] The display control function 555 causes the electronic medical record information 31 of the patient specified by the patient code to be displayed (step S2).

[0061] The examination order input function 551 receives an input of an examination order for requesting imaging of the patient's X-ray image data (step S3).

[0062] The notification determination function 554 determines whether the content of the examination order is an alert target item based on the alert master 32 (step S4). If it is not an alert target item (step S4; No), the information providing system 1 proceeds to step S10.

[0063] If it is an alert target item (step S4; Yes), the exposure dose prediction function 553 predicts the exposure dose based on the examination order received by the examination order input function 551 and the radiation master 33 (step S5).

[0064] The notification determination function 554 determines whether the total value of the cumulative value of the exposure dose within the set period and the predicted value of the predicted exposure dose exceeds the threshold (step S6). If it is less than the threshold (step S6; No), the operation terminal 50 proceeds to step S10.

[0065] When it is above the threshold value (step S6; Yes), the display control function 555 causes the summary screen 100 and the alternative item screen 200 to be displayed (step S7).

[0066] The inspection order input function 551 determines whether or not an input for accepting whether to acquire the X-ray image data indicated by the inspection order has been received (step S8). When an input for canceling the acquisition of the X-ray image data indicated by the inspection order has been received (step S8; No), the information providing system 1 ends the information providing process.

[0067] When an input for acquiring the X-ray image data indicated by the inspection order has been received (step S8; Yes), the display control function 555 accepts an input of the reason for acquisition on the reason input screen (step S9).

[0068] The inspection order issuing function 556 issues the inspection order information 35 (step S10).

[0069] Thus, the information providing system 1 ends the information providing process.

[0070] As described above, when the patient code indicating the patient photographed by the modality 10 is input, the operation terminal 50 according to the present embodiment acquires the record of the exposure dose of the patient from the exposure dose record information 41. Then, the operation terminal 50 displays the summary screen 100 that aggregates the record of the exposure dose of the patient. Thereby, the medical staff can determine whether or not to acquire the X-ray image data of the patient while referring to the exposure dose of the patient. That is, the operation terminal 50 can provide information for determining whether or not the benefit of the patient by imaging exceeds the loss.

[0071] In the above-described embodiment, it was explained that the display control function 555 displays the summary screen 100 when the sum of the cumulative value of the exposure dose and the predicted value of the exposure dose is equal to or greater than the threshold value. However, the display control function 555 may display the summary screen 100 when the content of the examination order is an alert target item and the sum of the cumulative value of the exposure dose and the predicted value of the exposure dose is less than the threshold value. The summary screen 100 displays the cumulative value of the exposure dose, the total value of the cumulative value and the predicted value of the exposure dose, and the like. Therefore, medical staff can determine whether to perform imaging by the imaging diagnostic apparatus in consideration of the exposure dose up to the current time.

[0072] In the above-described embodiment, it was explained that the operation terminal 50 includes the data acquisition function 552, the exposure dose prediction function 553, the notification determination function 554, the examination order issuance function 556, and the threshold setting function 557. However, all or some of the functions of the data acquisition function 552, the exposure dose prediction function 553, the notification determination function 554, the examination order issuance function 556, and the threshold setting function 557 may be provided by the HIS 30, or all or some of the exposure dose prediction function 553, the notification determination function 554, and the threshold setting function 557 may be provided by the RIS 40.

[0073] Although several embodiments have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, replacements, changes, and combinations of the embodiments can be made without departing from the gist of the invention. These embodiments and their modifications are included in the scope and gist of the invention, and are also included in the invention described in the claims and its equivalent scope.
