DETAILED DESCRIPTION OF THE INVENTION

[0013] A dose management apparatus, a program, a dose management system, and a dose management method according to preferred embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0014] [Configuration example of medical information management system 1] FIG. 1 is a diagram showing an example of a schematic configuration of a medical information management system 1 according to this embodiment. The medical information management system 1 includes an examination device 10, a medical image storage device 20, a dose management device 30, and a client terminal 40. The examination device 10, the medical image storage device 20, the dose management device 30, and the client terminal 40 are communicably connected via a network N. Examples of the network N include a LAN, the Internet, and a WAN. LAN is an abbreviation for Local Area Network. WAN is an abbreviation for Wide Area Network. The communication method of the network N may be wired communication or wireless communication. Each device constituting the medical information management system 1 conforms to the DICOM standard, and communication between the devices is performed in accordance with the DICOM standard. DICOM is an abbreviation for Digital Image and Communications in Medicine.

[0015] The examination device 10 is a modality such as a CT device, a general X-ray imaging device such as DR or CR, a nuclear medicine examination device, or a mammography device. The examination device 10 images a predetermined imaging region of a subject based on imaging conditions set by a console (not shown). The imaging includes still image imaging and dynamic imaging. The examination device 10 generates image data of a radiographic image based on the detection results of radiation irradiated to the patient (subject). The examination device 10 generates a DICOM image file by attaching additional information to the radiographic image. The additional information includes patient information, examination information, image information, etc. Patient information is information about the patient. Patient information includes patient ID, patient name, date of birth, gender, height, weight, age, BMI, etc. Image information is information about the image. Image information includes SOP instance UID, image date, image time, image number, etc.

[0016] The examination apparatus 10 generates an RDSR (Radiation Dose Structured Report) that handles dose information related to the examination. RDSR is an abbreviation for Radiation Dose Structured Report. The examination apparatus 10 transmits image data of the generated radiation image to the medical image archiving apparatus 20, and transmits the RDSR to the medical image archiving apparatus 20, the dose management apparatus 30, etc. The RDSR is information conforming to the DICOM standard and includes dose information related to the radiation dose (amount of energy) of radiation received by the subject during the examination. Specifically, the RDSR includes an Acquisition Protocol, which is an imaging protocol indicating the imaging region and imaging range during the examination. The imaging protocol is an example of first dose information. If the examination apparatus 10 is a CT apparatus, the RDSR includes indices that indicate the irradiation dose, such as DLP and CTDIvol. DLP is an abbreviation for Dose Length Product. The RDSR further includes information such as the tube voltage, tube current, and radiation exposure time applied for radiation irradiation.

[0017] The inspection device 10 generates an RDSR for each radiation irradiation event. An irradiation event is a set of radiation irradiation operations on a subject. An irradiation event is usually a series of irradiation operations under the same irradiation conditions. In each irradiation event, one or more radiation images are generated according to the radiation irradiation. An irradiation event occurs each time a new radiation irradiation is started. For example, an irradiation event occurs when the radiation irradiation conditions are changed, or when the imaging region of the subject is changed.

[0018] The medical image storage device 20 stores and manages the image data of the radiation images generated by the examination device 10 and the dose information included in the RDSR for each patient and each examination. For example, a PACS or the like can be used as the medical image storage device 20. PACS is an abbreviation for Picture Archiving and Communication System.

[0019] [Configuration example of dose management device 30] The dose management device 30 is configured by a computer and manages patient dose information when capturing a radiological image. Fig. 2 is a block diagram of the dose management device 30 according to this embodiment. The dose management device 30 includes a control unit 31, a storage unit 32, and a communication unit 33. The control unit 31, the storage unit 32, and the communication unit 33 are connected to each other via wiring such as a bus 34.

[0020] The control unit 31 includes a processor such as a CPU and a memory such as a RAM. CPU is an abbreviation for Central Processing Unit. RAM is an abbreviation for Random Access Memory. The control unit 31 comprehensively controls the processing operations of each unit of the dose management device 30. Specifically, the CPU executes a program P (described later) stored in the memory unit 32 to perform processing related to dose management, etc.

[0021] In this embodiment, the control unit 31 functions as an acquisition unit, a setting unit, and an output unit. A processor such as a CPU of the control unit 31 executes a program P stored in the storage unit 32, for example, to realize the functions of the acquisition unit, setting unit, output unit, etc. The acquisition unit acquires second dose information to be displayed in the dose management report based on first dose information related to the patient's examination transmitted from the examination apparatus 10. The first dose information is information related to the imaging protocol included in the RDSR as described above. The imaging protocol is a technical term that is difficult for patients to understand. The second dose information includes information related to the imaging region corresponding to the imaging protocol. Information related to the imaging region is a commonly used term that is easy for patients to understand. The acquisition unit can convert the imaging protocol into information related to the corresponding imaging region, for example, by using a table in which the imaging protocol of the first dose information is associated with the imaging region of the second dose information.

[0022] The setting unit can set a reference value for radiation exposure dose during an examination. The reference value is, for example, the radiation exposure dose for each patient's weight or BMI. BMI stands for Body Mass Index. BMI can be calculated using the following formula: BMI=Weight (kg) ÷ Height (m) ÷ Height (m) The setting unit sets a reference value for each BMI corresponding to each imaging region based on a coefficient input on a setting screen 100 (described later) and a preset reference value. The output unit outputs a medical radiation exposure dose report (described later) including the imaging region, which is the second dose information, the reference value of the radiation exposure dose corresponding to the imaging region, and the radiation exposure dose of the patient during the current examination, to, for example, the client terminal 40.

[0023] The storage unit 32 includes at least one storage module selected from the group consisting of an HDD, an SSD, a ROM, and a RAM. HDD is an abbreviation for Hard Disk Drive. SSD is an abbreviation for Solid State Drive. ROM is an abbreviation for Read Only Memory. The storage unit 32 stores a program P for executing dose management, various data, etc. The storage unit 32 stores a table T for acquiring the imaging region associated with the imaging protocol transmitted from the examination device 10. The table T will be described later.

[0024] The communication unit 33 is configured with a network interface, etc. The communication unit 33 transmits and receives data and signals to and from external devices such as the examination device 10 and the client terminal 40 connected via the network N. For example, the communication unit 33 receives an RDSR including image data of a radiographic image obtained by capturing an image of a patient and dose information at the time of capturing the image, transmitted from the examination device 10.

[0025] 3 does not include a display unit or an operation unit, but the present invention is not limited to this. For example, the dose management device 30 may include a display unit and an operation unit. In this case, the display unit and the operation unit of the dose management device 30 may be used to create the table T, or a medical exposure dose report (described later) may be displayed on the display unit.

[0026] [Configuration example of client terminal 40] The client terminal 40 is configured, for example, by a personal computer or the like. The client terminal 40 is used by a user, such as a doctor or radiologist, and displays radiographic images and dose information related to an examination in response to a viewing request from the user. FIG. 3 is a block diagram of the client terminal 40 according to this embodiment. The client terminal 40 includes a control unit 41, a display unit 42, an operation unit 43, a communication unit 44, and a storage unit 45. The control unit 41, the display unit 42, the operation unit 43, the communication unit 44, and the storage unit 45 are connected to one another by wiring such as a bus 46.

[0027] The control unit 41 has a processor such as a CPU, RAM, etc. The control unit 41 comprehensively controls the processing operations of each unit of the client terminal 40. Specifically, the CPU reads out various processing programs stored in the ROM, loads them into the RAM, and performs various processes in cooperation with the programs.

[0028] The display unit 42 has a display such as an LCD or an organic EL. LCD is an abbreviation for Liquid Crystal Display. EL is an abbreviation for Electro Luminescence. The display unit 42 displays various screens in accordance with instructions of display signals supplied from the control unit 41. The operation unit 43 has at least one of a keyboard including various function keys and a pointing device such as a mouse. The operation unit 43 receives instructions such as key operations and mouse operations from the user, and outputs operation signals according to the received instructions to the control unit 41. The operation unit 43 may be a touch panel combined with the display unit 42.

[0029] The communication unit 44 is configured by a network interface or the like. The communication unit 44 transmits and receives data, signals, and the like to and from external devices such as the radiation dose management device 30 via the network N. The storage unit 45 includes at least one storage module selected from the group consisting of an HDD, an SSD, a ROM, and a RAM. Various types of data are stored in the storage unit 45.

[0030] [Workflow for linking imaging protocols and imaging areas] 4 is a flowchart showing an example of a process flow for linking an imaging protocol with an imaging region and setting a reference value of radiation exposure dose for each imaging region according to this embodiment. The linking of an imaging protocol with an imaging region and the like are performed by a user such as a radiologist before the start of an actual examination. The following describes a case where the linking process and the like are performed using, for example, the client terminal 40.

[0031] The user sets the imaging region corresponding to the imaging protocol (step S10). FIG. 5A is a diagram showing an example of an imaging protocol included in the RDSR transmitted from the examination device 10 when the examination device 10 according to this embodiment is a CT device. For example, when the imaging region during the examination is "neck, chest, abdomen, groin," the RDSR includes "[CE] Neck-Groin" as the imaging protocol. When the imaging region during the examination is "head," the RDSR includes "[CE] Head-Conventional" as the imaging protocol. FIG. 5B is a diagram showing an example of another imaging protocol included in the RDSR transmitted from the examination device 10 according to this embodiment when the examination device 10 is a CT device. For example, when the imaging region during the examination is "neck, chest, abdomen, groin," the RDSR includes "04_Neck_Pelvis_Routine_Neck (Adult)" as the imaging protocol. When the imaging region during the examination is "head," the RDSR includes "04_Brain_Helical (Adult)" as the imaging protocol.

[0032] FIG. 6 is a diagram showing an example of a setting screen 100 for associating an imaging protocol with an imaging region according to this embodiment and setting a reference value of radiation exposure dose for each imaging region. When a user selects an operation button or the like for performing the association operation, the control unit 31 causes the display unit 42 to display the setting screen 100. An imaging protocol display unit 110 is provided on the left side of the setting screen 100. A list of imaging protocols is displayed on the imaging protocol display unit 110. The imaging protocols may be stored as initial settings in the storage unit 32 or the like, or the user can add, delete, or the like. Check boxes 120 are provided on the right side of the setting screen 100 for selecting an imaging region corresponding to the imaging protocol displayed on the imaging protocol display unit 110. A check box 120 is provided for each imaging region.

[0033] For example, when the user selects “[CE] Chest (0.5×80)” in the imaging protocol display section 110, the user selects the check box 120 for “chest” as the corresponding imaging region. This links the imaging protocol “[CE] Chest (0.5×80)” with the imaging region “chest.” Based on the user's selection operation, the control section 31 links “[CE] Chest (0.5×80)” with the imaging region “chest” and stores the links in the storage section 32. This linking operation is performed for all imaging protocols in the imaging protocol display section 410.

[0034] The user sets a BMI coefficient and other parameters for calculating a reference value of radiation dose for each BMI (step S11). A coefficient setting unit 130 is provided in the lower right corner of the setting screen 100 shown in FIG. 6. In this embodiment, BMI is divided into, for example, four ranges. A coefficient setting unit 130 is provided for each of the four divided BMI ranges. The user can set a coefficient for each divided BMI by inputting a numerical value into each coefficient setting unit 130 through the operation unit 43. A default value may be preset in the input field for each BMI in the coefficient setting unit 130. When the user selects the check box 120 for a specific imaging region and inputs a coefficient into the coefficient setting unit 130, the control unit 31 calculates a reference value of radiation dose corresponding to the set imaging region for each BMI. Specifically, the control unit 31 calculates a reference value for each BMI by multiplying the preset reference value of radiation dose for each imaging region by the coefficient input into each coefficient setting unit 130. In this embodiment, BMI is divided into a plurality of ranges, and a reference value of radiation exposure dose is set for each divided range, but this is not limited to this. For example, weight may be used instead of BMI. In this case, weight is divided into a plurality of ranges, and a reference value of radiation exposure dose is set for each divided range.

[0035] In this embodiment, the reference value of the patient's radiation exposure dose is displayed using a box and whiskers in a medical radiation exposure dose report, which will be described later. For this reason, the setting screen 100 is provided with a box and whiskers setting section 140 for setting the reference value. The box and whiskers setting section 140 is provided with input fields for setting a reference dose value (median), which is the reference value of the radiation exposure dose, and an upper limit and a lower limit for the reference value. Default values ​​may be set in advance in the input fields for the reference dose value (median), upper limit, and lower limit.

[0036] The control unit 31 stores the imaging protocol, the imaging region associated with the imaging protocol, and the reference value of the radiation dose for each BMI for each imaging region in the storage unit 32 in association with each other (step S12). In this case, the control unit 31 may create a table T in which the imaging protocol, the imaging region, and the reference value of the radiation dose for each BMI for each imaging region are stored in association with each other. FIG. 7 is a diagram showing an example of the configuration of table T according to this embodiment. For example, table T stores the imaging protocol "[CE] Head - Conventional (Head First)," the "Head" associated with this imaging protocol, and the reference value of each BMI for this "Head," all associated with each other. The contents of table T can be updated at any time. When creating a medical radiation dose report, the control unit 31 acquires the imaging region associated with the imaging protocol received from the examination apparatus 10 from table T, and then acquires the reference value for each BMI corresponding to the acquired imaging region from table T.

[0037] [Example of operation of Medical Information Management System 1] 8 is a flowchart showing an example of the operation of the dose management device 30 when creating a medical exposure dose report 200 according to this embodiment. A processor such as a CPU of the control unit 31 executes a program P stored in the storage unit 32, thereby realizing processing including an acquisition step, an acquisition step, etc.

[0038] When imaging of a predetermined imaging region is completed, an RDSR including dose information related to the examination is transmitted from the examination apparatus 10 to the dose management apparatus 30. The communication unit 33 of the dose management apparatus 30 receives the RDSR from the examination apparatus 10. The control unit 31 acquires the imaging protocol indicating the imaging region during the examination included in the received RDSR (step S20). The control unit 31 acquires the imaging protocol from the Acquisition Protocol name included in the RDSR. For example, the control unit 31 acquires from the RDSR the imaging protocols "[CE] Head - Conventional (Head First)" and "[NR CE] Neck + Chest - Groin (2 scans)" that indicate the imaging region and imaging range where the actual examination was performed.

[0039] The control unit 31 acquires from Table T the imaging region associated with the acquired imaging protocol and the reference value of the exposure dose for each BMI corresponding to this imaging region (step S21). For example, if the first imaging protocol is “[CE] Head-Conventional (HeadFirst)” and the patient's BMI is less than 18.5, the control unit 31 acquires from Table T the imaging region “Head” and the reference value “1000.” If the second imaging protocol is “[NR CE] Neck + Chest-Inguinal (2 scans)” and the patient's BMI is less than 18.5, the control unit 31 acquires from Table T the imaging region “Neck, Chest, Abdomen, Pelvis” and the reference value “1080.” Information regarding the patient's BMI may be acquired from, for example, the RDSR. In this way, for example, by using Table T, imaging protocols expressed in technical terms can be converted into general terms that the patient can easily understand.

[0040] The control unit 31 acquires dose information indicating the radiation dose of the patient during the current examination (step S22). For example, if the examination apparatus 10 is a CT apparatus, the control unit 31 acquires CTDIvol and DLP as indices of radiation dose from the CT apparatus. The dose information regarding CTDIvol and DLP is included in the RDSR transmitted from the CT apparatus.

[0041] When the examination device 10 is a general X-ray imaging device, the control unit 31 calculates the incident surface dose, which indicates the radiation dose to which the patient will be exposed during the examination, based on the subject thickness of a patient with a predetermined standard body shape and information such as the tube current and tube voltage included in the received RDSR. The incident surface dose can be calculated using the following formula (1). The incident surface dose is also called the patient's skin surface absorbed dose. Entrance surface dose (mGy) = NDD-M(f) × mAs × (1 / SSD) 2 …(1) NDD-M(f): Coefficient based on tube voltage and total filtration (inverter) mAs: tube current x exposure time SSD: Focal skin distance (m)

[0042] The control unit 31 creates a medical radiation exposure dose report including the acquired dose information indicating the radiation exposure dose of the patient this time, information about the imaging region acquired from the table T, the reference value of the radiation exposure dose corresponding to this imaging region, etc. The control unit 31 outputs data of the created medical radiation exposure dose report to the client terminal 40 (step S22).

[0043] 9 is a diagram showing an example of a medical radiation dose report 200 displayed on the display unit 42 of the client terminal 40 according to this embodiment. The medical radiation dose report 200 is provided with a patient information display unit 210, a radiation dose display unit 220, a target dose display unit 230, and a quick reference display unit 240. For example, if the examination device 10 is a CT device and an examination is performed on the "head" and "neck, chest, abdomen, and pelvis" as the imaging site and imaging range, the medical radiation dose report 200 will be displayed as follows:

[0044] Patient information of the patient who has undergone the current examination is displayed on the patient information display section 210. Examples of patient information include the date of imaging, examination room, ID, name, date of birth, age, and sex.

[0045] The radiation dose display unit 220 is a display area for clearly showing which parts of the patient were exposed to radiation and to what extent during the current examination. The radiation dose display unit 220 displays a diagram of the human body, which is a schematic representation of the human body, and this diagram is divided into, for example, nine parts according to the imaging region. In this embodiment, since the "head" and "neck, chest, abdomen, and pelvis" are exposed to radiation during the examination, the "head, neck, chest, abdomen, and pelvis" are highlighted in a color different from that of the other imaging regions. On the body diagram, the radiation dose value during the scan of the "head" is displayed in a pop-up display near the head on the body diagram. Similarly, the radiation dose value for the entire scan range of the "neck, chest, abdomen, and pelvis" is displayed in a pop-up display near the pelvis on the body diagram, for example.

[0046] The reference dose display section 230 is a display area for comparing and displaying the reference value of the radiation dose for each imaging region and the radiation dose of the patient during the current examination. Specifically, the reference dose display section 230 displays the reference value of the radiation dose for the imaging region (reference dose value) and the actual radiation dose during the current examination on the same graph. The horizontal axis of the graph represents Total DLP. In this embodiment, the reference dose display section 230 displays a dose graph 230A for the "head" and a dose graph 230B for the "neck, chest, abdomen, and pelvis" regions, respectively. In the dose graphs 230A and 230B, the reference values ​​of the radiation dose are displayed using box and whiskers 231. The box and whiskers 231 each include a median, an upper limit, and a lower limit. The median, upper limit, and lower limit are values ​​set in the box and whisker setting section 140 on the setting screen 100 shown in FIG. 6. In dose graphs 230A and 230B, the radiation dose during the current examination is displayed, for example, by a star mark 232. For example, in dose graph 230A for the "head," the median of the reference values ​​is 1000 mGy·cm, and the lower and upper limits are set to ±100 mGy·cm from the median. The radiation dose during the "head" examination is 948.2 mGy·cm, and is displayed superimposed on box and whiskers 231. This allows the patient to visually understand that the radiation dose during this examination is within the range of the reference values. Note that the reference values ​​may be displayed in a manner that does not use box and whiskers 231.

[0047] The quick reference display unit 240 displays radiation exposure doses in general surrounding areas. For example, the quick reference display unit 240 displays "natural radiation" which indicates the radiation exposure dose when boarding an airplane, "artificial radiation" which indicates the radiation exposure dose when undergoing a CT scan, and so on.

[0048] According to this embodiment, by referring to Table T, for example, it is possible to obtain information about the imaging region from the imaging protocol included in the RDSR transmitted from the examination apparatus 10. In other words, it is possible to convert the terminology of the imaging protocol, which includes technical expressions included in the RDSR, into commonly used terms for the imaging region that are easy for patients to understand. This makes it possible to provide the patient with a medical radiation exposure dose report 200 that uses fewer technical terms and is easy to understand.

[0049] According to this embodiment, the medical radiation exposure dose report 200 displays the imaging region associated with the imaging protocol transmitted from the examination apparatus 10, the reference value of the radiation exposure dose corresponding to the imaging region, and the radiation exposure dose during the current examination. This allows the patient to accurately and quickly confirm which region was imaged during the examination and whether the radiation exposure dose during the examination was appropriate. Furthermore, in this embodiment, the allowable range of the reference value of the radiation exposure dose is displayed using a box and whiskers 231, and the radiation exposure dose during the current examination is displayed superimposed on the same graph. This allows the patient to visually understand whether the radiation exposure dose during the current examination meets the reference value, making it easy to understand the contents of the medical radiation exposure dose report 200.

[0050] Conventionally, diagnostic reference levels (DRLs), which indicate standard values ​​for radiation exposure dose, are targeted at a weight range of 50 to 70 kg. However, radiation exposure doses vary depending on body weight. Therefore, if the standard values ​​of DRLs are used for an obese patient in the medical radiation exposure dose report 200, the radiation exposure may exceed the standard value indicated by the DRLs even if the radiation exposure is within the acceptable range. In such cases, the patient may feel anxious. According to this embodiment, the standard values ​​of radiation exposure dose are set for each BMI or body weight, so that the standard values ​​of radiation exposure dose can be set for each medical facility without using DRLs. This allows the standard values ​​of radiation exposure dose to be set according to the patient's BMI or body weight, making it possible to present the patient with a medical radiation exposure dose report 200 related to the radiation exposure dose appropriate for each patient's body shape. This reduces the possibility of the patient feeling anxious.
