The X-ray diagnostic apparatus 10 includes a high voltage generator 12, an X-ray tube device 13, an X-ray detector 14, and an input / output unit 15 with the processing unit 11 as a center. The processing unit 11 manages the inspection protocol. The examination protocol includes data for specifying the type of examination technique. The types of techniques using the X-ray diagnostic apparatus 10 are roughly classified into, for example, simple X-ray imaging and intervention in X-ray fluoroscopy. As the intervention, for example, there are various techniques such as angioplasty and vascular embolization using a catheter and a stent, and arrhythmia treatment using an ablation catheter. The high voltage generator 12 applies a high voltage to the X-ray tube device 13 according to the control of the processing unit 11. The X-ray tube device 13 receives an application of a high voltage and generates X-rays. The X-ray detector 14 detects X-rays generated from the X-ray tube device 13 and transmitted through the subject P, and generates X-ray image data relating to the subject P. A part of the X-rays from the X-ray tube device 13 is scattered by the subject P. A medical worker may be exposed by this scattered X-ray or the like. The input / output unit 15 transmits the inspection protocol data to the HIS / RIS device 30 via the network.

  The dosimeter 20 is a device that measures the exposure dose of a medical worker. Specifically, the dosimeter 20 includes a detection unit 21, an input / output unit 22, and a processing unit 23. The detection unit 21 is attached to a specific attachment site of a medical worker. Examples of the attachment site include human body sites such as the chest and abdomen. As the detecting unit 21, a pocket dosimeter, a film badge, or the like is used. The detection unit 21 detects X-rays that have reached the wearing site, and generates an electrical signal corresponding to the detected X-ray dose. The generated electrical signal is input to the input / output unit 22 via a cable. The processing unit 23 calculates the exposure dose based on the intensity of the electrical signal input to the input / output unit 22. The exposure dose is integrated in the examination unit. The accumulated dose is managed in units of medical personnel such as operators and staff, or in units of wearing parts (in human body parts). The accumulated dose data is transmitted to the HIS / RIS device 30 via the network by the input / output unit 22 in association with the name of the medical worker, the name of the human body part, the examination date and time, and the type of technique.

  The HIS / RIS device 30 is a computer terminal that manages data related to surgical procedures and medical personnel. The HIS / RIS apparatus 30 includes an input / output unit 32, an integrated dose storage unit 33, a standard dose storage unit 34, and a schedule storage unit 35 with the data processing unit 31 as a center.

Specifically, the standard dose storage unit 34 stores a table (hereinafter, referred to as a standard dose table) in which an operation type code is associated with a standard dose. The standard exposure dose is an average integrated exposure dose during the examination of the medical staff when the surgical examination is performed as usual. For example, the standard exposure dose may be calculated based on the past accumulated dose stored in the accumulated dose storage unit 33 for each type of technique. The standard exposure dose may be set to an arbitrary value by the user. The schedule storage unit 35 stores a surgical schedule (clinical participation plan) for each of a plurality of medical workers. Each medical worker's schedule is associated with the date and time of the examination and the code of the type of examination method scheduled to participate in the date and time. For example, the schedule includes information such that the medical worker A participates in the examination of the operation method B from E time to F time on C month D.

  The dose determination device 40 is a computer terminal connected to a network. The dose determination apparatus 40 includes an input / output unit 42, an operation unit 43, a dose determination unit 44, a display unit 45, and a storage unit 46 with the control unit 41 as a center.

  The input / output unit 42 transmits / receives various data to / from the HIS / RIS apparatus 30 via the network. Further, the input / output unit 42 supplies an input signal input via the operation unit 43 to the control unit 41.

  The operation unit 43 receives various instructions from the user via the input device. An input signal corresponding to an instruction from the user is supplied to the control unit 41 via the input / output unit 42. For example, the operation unit 43 specifies the management target person and the dose management period for the management target person in accordance with an instruction from the user via the input device. The management target person is designated from among a plurality of medical workers who are familiar with the surgical schedule management in the schedule storage unit 35. The dose management period is a period for which the dose determination unit 44 determines the exposure dose. The dose management period includes both a future period after the dose determination process and a past period before the dose determination process. In the future period, the predicted exposure dose of the management subject is determined. In the past period, the measured exposure dose of the management subject is determined. As an input device, a pointing device such as a mouse or a trackball, a selection device such as a mode switch, or an input device such as a keyboard can be used as appropriate.

  The dose determination unit 44 determines the exposure dose of the designated management subject during the dose management period. Specifically, the dose determination unit 44 includes a predicted dose determination unit 441 and an actually measured dose determination unit 442.

  The control unit 41 functions as the center of the dose determination device 40. The control unit 41 reads the exposure dose management program from the storage unit 46, and controls each unit in the dose determination apparatus 40 according to the read exposure dose management program. By executing the exposure dose management program, the predicted exposure dose in the dose management period of the management subject is determined and notified to the user of the dose determination device 40.

  Hereinafter, an operation example of the exposure dose management system 1 according to the present embodiment will be described.

  FIG. 3 is a diagram illustrating a typical flow of the exposure dose determination / notification process performed under the control of the control unit 41.

  The control unit 41 reads out the exposure dose management program from the storage unit 46 and executes the exposure dose management program when the user gives an instruction to start the exposure dose determination / notification process via the operation unit 43. The dose determination / informing process is started.

  In the exposure dose determination / notification process, first, the control unit 41 waits for a user to designate a management target and a dose management period via the operation unit 43 (step SA1). The management subject is designated by inputting the name of a medical worker. The dose management period is specified in units of months, weeks, or days, for example. The future period and the past period in the dose management period are automatically assigned from the dose management period in accordance with a predetermined rule. For example, when the dose management period is one month, one week may be set as a future period, and the remaining three weeks may be set as a past period. Note that the future period and the past period may be individually specified via the operation unit 43.

  When step SA1 is performed, the control unit 41 causes the predicted dose determination unit 441 of the dose determination unit 44 to perform a process for determining the predicted exposure dose (step SA2). In step SA <b> 2, the predicted dose determination unit 441 identifies all the techniques that the management subject is scheduled to participate in the dose management period from the schedule storage unit 35, and associates all the techniques associated with all the identified techniques. The standard exposure dose is specified from the standard dose storage unit 34, and the predicted exposure dose is determined based on all the specified standard exposure doses. The process of step SA2 will be specifically described below.

  FIG. 4 is a diagram illustrating a typical flow of the predicted dose determination process by the predicted dose determination unit 441. As shown in FIG. 4, the predicted dose determination unit 441 identifies all the techniques that the management target person will participate in the future period from the schedule of the management person's technique (step SA21). Specifically, first, the input / output unit 42 receives the schedule data of the management subject from the schedule storage unit 35 of the HIS / RIS device 30 through the network according to the control of the control unit 41. The received schedule data is supplied to the predicted dose determination unit 441 via the control unit 41. The predicted dose determination unit 441 identifies all the techniques that the management subject is scheduled to participate in the future period from the supplied schedule. More specifically, the schedule is searched using the examination date and time included in the future period as a search key, and the type of technique associated with the search key is counted. As a result, the type and number of techniques scheduled to participate in the management subject in the future period are specified. For example, information such as “method A is performed three times and method B is performed twice within one week from the present time” is specified.

  The management target person's schedule data may be stored in the storage unit 46 in advance. In this case, in step SA <b> 21, the control unit 41 supplies management target person schedule data from the storage unit 46 to the predicted dose determination unit 441. The predicted dose determination unit 441 uses this schedule as described above to specify the surgical procedure.

  When step SA21 is performed, the predicted dose determination unit 441 identifies the standard exposure dose of the type of operation specified in step SA21 from the standard dose table (step SA22). Specifically, first, the input / output unit 42 receives data of the standard dose table from the standard dose storage unit 34 of the HIS / RIS apparatus 30 through the network in accordance with control by the control unit 41. The received standard dose table data is supplied to the predicted dose determination unit 441 via the control unit 41. The predicted dose determination unit 441 searches the standard dose table using the type of technique specified in step SA21 as a search key, and specifies the standard dose associated with the search key on the standard dose table. For example, information such as “the standard exposure dose for method A is 10 mSv and the standard dose for method B is 5 mSv” is specified.

  Note that the data of the standard dose table may be stored in the storage unit 46 in advance. In this case, in step SA22, the control unit 41 supplies the standard dose table data from the storage unit 46 to the predicted dose determination unit 441. The predicted dose determination unit 441 specifies the standard dose using the standard dose table as described above.

  When step SA22 is performed, the predicted dose determination unit 441 determines the predicted exposure dose in the future period of the management subject (step SA23). More specifically, the predicted dose determination unit 441 adds the standard exposure dose specified in step SA22 by the number of times scheduled in the future period for each type of technique. Thereby, the addition value of the standard exposure dose is calculated for each type of surgical procedure. The calculated added value is used as the predicted exposure dose. Further, the predicted exposure dose may be calculated by multiplying the added value by a parameter corresponding to the participation time of the medical worker's examination and the distance between the medical worker and the X-ray diagnostic apparatus 10.

  When step SA23 is performed, the predicted dose determination process by the predicted dose determination unit 441 ends.

  In addition, when step SA1 is performed, the control unit 41 causes the actual dose determining unit 442 of the dose determining unit 44 to perform the process of determining the actual exposure dose in parallel with step SA2 (step SA3). In step SA3, the actually measured dose determining unit 442 uses the management target person specified in step SA1 and the dose management period to calculate the dose (actually measured dose) that the management target person actually exposed in the past period. Use to determine. Specifically, first, according to control by the control unit 41, the input / output unit 42 receives data on a list of integrated doses related to the management subject from the integrated dose storage unit 33 of the HIS / RIS apparatus 30 via the network. The received list data is supplied to the measured dose determination unit 442 via the control unit 41. The actually measured dose determining unit 442 identifies the actually measured dose in the past period from the supplied list. More specifically, the list is searched using the examination date and time included in the past period as a search key, and the integrated dose associated with the search key is integrated. The integrated value of the integrated dose is calculated as the actually measured exposure dose.

  When Steps SA2 and SA3 are performed, the control unit 41 causes the display unit 45 to perform display processing (Step SA4). In step SA4, the display unit 45 displays the predicted exposure dose determined in step SA2 and the actual exposure dose determined in step SA3 in a predetermined display layout.

  FIG. 5 is a diagram illustrating an example of a display layout of the predicted exposure dose and the actual exposure dose. In FIG. 5, it is assumed that the dose management period is one month, the future period is one week, and the past period is three weeks. The predicted exposure dose YS and the actual measurement exposure dose ZS are, for example, defined as the dose value on the vertical axis and the reference time of the dose management period (in other words, at the time when the dose determination process is performed) on the horizontal axis. Displayed as a bar graph. The total of the predicted exposure dose and the actual exposure dose at one reference time is represented by one bar. In FIG. 5, a bar for the reference time last week and a bar for the current week are shown. That is, the height of the bar B1 indicates the sum of the predicted exposure dose determined by the dose determination unit 44 in the last week and the actual exposure dose, and the height of the bar B2 is determined by the dose determination unit 44 this week. The total of the determined predicted exposure dose and the actual exposure dose is shown.

  As shown in FIG. 5, in order to examine the exposure dose in more detail, the display unit 45 may divide and display the total value in units of a certain period. For example, in the case of FIG. 5, the actually measured exposure dose ZS in the past period is shown divided into units of one week. Specifically, the actual measured dose ZS for the entire past period is divided into the actual measured dose ZS1 of this week, the actual measured dose ZS2 of the previous week, and the actual measured dose ZS of the previous week calculated from the reference time. Note that the predicted exposure dose YS of the bar B1 and the actual exposure dose ZS1 of the bar B2 represent the exposure dose during the same period. Similarly, the actual exposure dose ZS1 of the bar B1 and the actual exposure dose ZS2 of the bar B2, the actual exposure ZS2 of the bar B1 and the actual exposure ZS3 of the bar B2 represent the exposure during the same period.

  As shown in FIG. 5, the display unit 45 may display the total value together with a preset limit value. The limit value is an upper limit value of the exposure dose allowed in the dose management period (one month in FIG. 5). The limit value is determined in advance according to the dose management period. The limit value may be calculated based on the integrated dose stored in the integrated dose storage unit 33. Thus, by displaying the total value and the limit value, it is possible to confirm whether or not the exposure dose of the management subject exceeds the limit value during the dose management period.

  The display unit 45 may display a history of total values. For example, as a history of total values, as shown in FIG. 5, the last week's bar B1 and this week's bar B2 are displayed on the same graph. In this way, by displaying the history of the total value, the exposure reduction effect can be confirmed. In order to confirm the exposure reduction effect in more detail, the display unit 45 may display the predicted exposure dose and the actual measurement dose at the same date and time on the same graph. For example, as shown in FIG. 5, “predicted exposure dose YS for next week” in bar B1 whose reference time is the reference time last week and “actual exposure dose ZS1 of this week” in bar B2 whose reference time is this week are on the same graph. By displaying, it is possible to promote understanding of the exposure reduction effect this week.

  If step SA4 is performed, the control part 41 will complete | finish an exposure dose determination / alerting | reporting process.

  In step SA1, a human body part may be further specified. The human body part is designated by inputting a human body part name such as a chest or an abdomen. When the human body part is designated, the predicted exposure dose related to the designated part (designated human part) of the management target person in the future period within the dose management period is determined in step SA2, and the designated part of the management target person in the past period is determined. The actually measured exposure dose is determined in step SA3. In step SA4, the predicted exposure dose and the actual measurement dose related to the designated site are displayed on the display unit 45.

  As described above, the exposure dose management system 1 according to the present embodiment can inform a medical worker or the like of the predicted exposure dose expected from now on. Therefore, the exposure dose management system 1 can prevent the exposure dose from exceeding the limit value, for example, by correcting the clinical participation plan of the medical staff and feedback to measures for reducing the exposure dose. Moreover, the medical worker etc. can confirm the exposure reduction effect by displaying the estimated exposure dose regarding the same date and time, and the measurement exposure dose side by side. Therefore, the exposure dose management system 1 leads to raising the awareness of the medical worker about the exposure dose.

  Thus, the exposure dose management system and the exposure dose management program according to the present embodiment can notify a predicted future exposure dose for a medical worker.

  In addition, when step SB1 is performed, the control unit 41 causes the actual dose determining unit 442 of the dose determining unit 44 to perform the process of determining the actual exposure dose in parallel with step SB2 (step SB3). In step SB3, the actually-measured dose determination unit 442 uses the accumulated dose storage unit 33 to calculate the dose (measured dose) that has been actually exposed to all medical staff in the past period from the dose management period specified in step SB1. decide. Specifically, the average value of the actually measured exposure dose in the past period is specified from the list of accumulated doses regarding all the medical workers working at the medical facility. More specifically, a list related to all medical workers is searched using the examination date and time included in the past period as a search key, and the integrated dose associated with the search key is integrated. Next, the average value of the accumulated dose is calculated by dividing the accumulated dose by the total number of medical staff involved in the examination. This value is calculated as an average value of the actually measured exposure dose of the entire medical facility.

  When Steps SB2 and SB3 are performed, the control unit 41 causes the display unit 45 to perform display processing (Step SB4).
