Description

[0001] The present invention relates to a radiation integrated management system for managing individual radiation dose information, and a real-time personal radiation dose management method using the same.

The present invention relates to a method for managing individual radiation doses and a service platform thereof. More particularly, the present invention relates to a method and system for managing radiation doses accumulated in a human body by managing radiation doses exposed in real time in a medical situation or a real life, A method for providing a service according to the radiation dose, and a service platform for the method.

Generally, radioactive materials are unstable and cause collapse of themselves. When these elements are collapsed and converted into other materials, they emit some particles or electromagnetic waves, which is radiation.

The radiation emitted is called a radioactive material or a radioactive isotope. The ability to emit radiation is called radioactivity. Radiation from radioactive material collapses is called alpha (alpha), beta (beta), gamma Ray, and neutron. However, in general, when referring to radiation, there are many cases in which not only these but also electromagnetic waves such as an X-ray or a heavy load transferor are mentioned together.

These radiation exist in nature and continue to affect our bodies. Radiation exposure is also closely related to carcinogenicity, and it is known that exposure to radiation above a certain threshold will lead to a rapid increase in carcinogenicity.

Typical radiation exposure pathways are X-ray radiographs, Computed Tomography (CT), Computed Radiography (CR), Magnetic Resonance Imaging (MRI), Positron Emission Tomography (PET), vascular imaging devices, angiography devices, Or the like, or is exposed to the amount of radiation existing in the real-life natural environment.

To this end, the detailed components of the radiation integrated management system 150 will be described with reference to FIG.

FIG. 2 is a diagram showing an example of the components of the radiation integrated management system according to the embodiment of the present invention.

Referring to FIG. 2, the radiation integrated management system 200 includes a communication unit 210 for performing data communication with an external system or a communication device, an overall operation control for each component of the system, And a database unit 230 for storing and managing information generated by the control unit 220. The control unit 220 includes a control unit 220,

The communication unit 210 includes a wired / wireless communication unit 211 for performing data communication with an external system or communication equipment, an interface unit 212 for inputting or transmitting data from a predetermined data storage device, (213).

The radiation integrated management system 200 performs data communication with a plurality of medical institution management systems or communication equipments through the communication unit 210 and can perform data communication related to the radiation dose through various paths. For example, radiation dose data may be received along with medical imaging information via medical imaging information, EMR, PHR, or portable radioactivity meters transmitted from a medical facility. Alternatively, the user may receive the radiation dose data measured through the portable radiation measuring device 120, or may receive the radiation dose data statistically based on the requirements in cooperation with the external information providing system.

The control unit 220 includes a data collecting unit 221 for collecting personalized radiation dose data through respective data collecting paths, a data processing unit for performing an arithmetic process for removing error information from the data collected by the data collecting unit 221 222), a DB generator 223 for generating individual radiation dose information DBs based on individual radiation exposure dose data processed by the data processor 222, and a DB for continuously managing the radiation dose management records constituting each of the generated DBs And a management unit 224.

Specifically, the data collecting unit 221 collects the radiation dose data exposed under a specific condition from a variety of information providing sources such as a medical institution system, a portable radiometer, and a radiation dose information DB. In addition, from the various information providing sources including the database unit 230, the user can retrieve the radiation dose data corresponding to the specific environment in which the user is exposed to the radiation, and supplement the missing radiation dose information.

The data processing unit 222 determines whether or not the radiation dose information matching the same or similar condition exists based on the radiation database unit 230 already built in the data collected by the data collecting unit 221, A series of arithmetic processing steps are performed to increase the accuracy of the data by comparing the stored radiation dose information with the collected information and correcting the error data.

For example, the data processing unit 222 calculates the radiation dose affecting the actual user according to the physical characteristics of the user such as sex, age, height, weight, Can be adjusted.

In Equation (1), the conversion factor indicates individual physical characteristics such as a user's sex, age, height, body weight, and radiation exposure site, and is a value for deriving an effective radiation exposure amount that can affect an actual user. The conversion factor is not a value fixed to a value that can be set based on the radiation amount information DB 252 based on the individual personal information, and may be changed as the time elapses. The operation symbol (*) used in Equation (1) is one example, but is not limited thereto.

The DB generation unit 223 generates an individual radiation dose information DB based on the data provided from the data processing unit 222. [ The individual radiation dose information DB can store the radiation exposure dose data together with the date, time, and environmental information of the user exposed to the radiation. FIG. 4 shows an example of the individual radiation dose information DB constructed according to the embodiment of the present invention, which will be described later with reference to FIG.

Referring again to FIG. 2, the DB management unit 224 continuously manages data stored in the individual radiation dose information DB. The amount of radiation accumulated in the human body may be annihilated naturally or disappearing by an artificial method (for example, radioactive removal treatment, dosing for radioactivity removal, food intake, etc.) after a predetermined time elapses depending on the conversion factor of the user Therefore, the DB management unit 224 can update the DB by adding, removing, or modifying data stored in the individual radiation dose information DB at predetermined intervals. In addition, the DB management unit 224 updates the cancer incidence information according to the individual cumulative radiation dose, and can continuously manage the data stored in the individual radiation dose information DB.

The database unit 230 includes a personalized radiation dose information DB 231 for storing individual radiation dose management details generated by the DB generating unit 223 and a radiation dose information DB 232 for storing and managing the past processed data can do.

The individual radiation dose information DB 231 is generated in the DB generator 223 and is calculated by the DB management unit 224 based on the time taken to disappear after a certain period of time from the exposure time of the radiation, Is updated every predetermined cycle.

The radiation dose information DB 232 is a kind of search DB for providing information necessary for data retrieval in the data collecting unit 221. The radiation dose information database 232 is a database for retrieving radiation dose data in a situation where a large number of users are exposed to current or past radiation, And information on radiation dose statistics formulated through academic research and the like in a specific requirement.

3 is a flowchart illustrating an example of a process of building a personalized radiation information DB in the radiation integrated management system according to the embodiment of the present invention.

As described above, the radiation integrated management system collects user-specific radiation exposure information from at least one of a plurality of the medical institution systems 310, the portable radioactivity meters 320, and the radiation dose information DB 330 in real time or at a predetermined period or event occurrence .

Referring to FIG. 3, when the user uses a medical service such as medical image information shooting through a radiation medical device for performing radiation exposure in a medical institution, the integrated radiation management system according to an embodiment of the present invention may include, The medical image information may be collected through the management system, the PACS, or a predetermined data storage device (e.g., a compact disc) provided by the user at the medical institution (S301).

When the data is collected, it is determined whether the radiation dose data irradiated to the user through the medical device, such as metadata or header information of the collected medical image information, is included (S302).

For example, the metadata of the medical image information provided by the medical institution system may include patient personal information, modality related to the image information, photographing site information, photographing place information, medical device information, Radiation dose information, and the like. In some cases, the meta data may further include area dose information, photographing article information, medical device serial information, and the like when capturing a medical image.

At this time, if metadata such as the meta data is included and the radiation dose amount data is included, the data objectification operation excluding the patient's personal information is performed (S303). The data in which the personal information is excluded is transmitted to the data processing unit 222 described above with reference to FIG.

Meanwhile, the radiation integrated management system can collect radiation dose data measured in daily life through a portable radiometer possessed by a user or a portable radiometer possessed by another person (S304).

At this time, the user can provide the radiation measurement state information of the radiation measurement date / time, the radiation measurement site, environmental information, etc. to the radiation integrated management system together with the measured radiation dose data. The data collected through the radioactivity measuring device is also transmitted to the data processing unit 222 described above with reference to FIG.

On the other hand, the radiation integrated management system can collect and collect radiation dose data that has been studied or statistically analyzed according to a specific requirement based on the radiation information DB already built up by the user (S305).

For example, if data is missing due to a specific environment in which the user may be exposed to radioactivity but is not equipped with a radioactivity meter, or information on a medical imaging device is missing from a specific medical institution and radiation dose data is missing, From the information DB, it is possible to retrieve and obtain the radiation dose data corresponding to the similar conditions of the same degree.

Data derived based on the radiation dose information DB is also transmitted to the data processor 222 described above with reference to FIG.

The data processing unit 222 is a data processing unit that generates data quantitatively quantitatively in the same or similar conditions based on the radiation dose information DB that has already been constructed for the radiation dose data collected through various data collection paths as described above in steps S301 to S305 (S306), and error information of the currently collected data is filtered using the formatted existing data (S306, S307).

For example, the error information filtering of the collected radiation dose data may be performed by using a conversion factor based on physical characteristics such as the user's sex, age, height, body weight, radiation exposure site, etc. with respect to the collected basic radiation exposure dose data, The effective radiation dose data may be derived for each user.

Accordingly, the DB generator 223 described above with reference to FIG. 2 can generate the individual corrected dose information DB together with the essential meta data and construct the individual DB (S308).

FIG. 4 is a view showing an example of individual radiation dose DB according to an embodiment of the present invention.

The information DB shown in FIG. 4 represents a basic radiation dose information DB constructed on the basis of medical image information collected from a medical institution through PACS as part of the individual radiation dose DB according to the embodiment of the present invention.

Referring to FIG. 4, the individual radiation dose DB 400 records at least one radiation dose information 430 together with the metadata 410 related to the medical image information, in order to facilitate the search of the subsequent radiation dose . The meta data of the radiation dose information DB can be divided into essential meta information (M) and optional meta information (O), and information input can be required when storing and acquiring data.

For example, the essential meta information M includes a measurement date 411, a modality 412, an exposed region 413, an exposure location 414, medical device information 415, The medical instrument information 421, the serial number 422 of the medical instrument, the radiation exposure area dose 423, the exposure time 424, the exposure time 422, Level 425, medical institution information 426, photographic article information 427, and the like.

The information DB illustrated in FIG. 4 shows the result of processing the data collected from the medical institution through the process of steps S301 to S303 in FIG. 3. The data collected through the portable radioactivity measuring device as in step S304, The information DB can be constructed by deriving necessary data from the pre-established radiation dose information DB as shown in FIG.

5 is a flowchart illustrating an example of a process of managing a personalized radiation information DB based on a radiation dose information DB constructed in a radiation integrated management system according to an embodiment of the present invention.

Referring to FIG. 5, in the integrated radiation management system according to an embodiment of the present invention, when information indicating that a current or past user has been exposed to radiation exposure in a medical institution or everyday life is input (S501), the radiation dose information (S502). At this time, the radiation dose information refers to information collected from a portable radiometer provided by a medical institution or an individual.

If the radiation dose information corresponding to the user's radiation exposure is not collected, the radiation integrated management system calculates the radiation dose information based on the radiation dose information DB 232, which is the same or similar to the requirement that the user is exposed to radiation The radiation dose data in the requirement is searched first (S503).

The data retrieved from the radiation dose information DB 232 at the time of the primary search may include information such as the metadata described in FIG. 4 with respect to the radiation dose data, whether or not the information related to the radiation exposure matches a predetermined reference value or more, As shown in FIG. At this time, the essential metadata and the option meta data described above can be integrated and retrieved as the matching information.

The established radiation dose information DB assumes that the radiation dose data in a situation where the user or another user has been exposed to the past radiation is collected and stored or the radiation dose information which is generally exposed to a person in a specific requirement is stored .

When there is radiation dose data matching the requested metadata in the primary search for the radiation dose information DB, the metadata and the radiation dose data are derived and recorded in the radiation exposure management record of the user's radiation dose information DB S504, S509).

On the other hand, if the requested meta data is not searched, the required meta data and the option meta data are separated and the radiation amount information DB is secondarily searched (S505). For example, the requested meta data may be matched, but the option meta data may be secondarily searched for the radiation dose information DB with data belonging to a predetermined similar condition range. This is for deriving data that meets the maximum similar condition when there is no data in the same situation as the situation in which the user is exposed to radiation.

As a result of the secondary search, if meta data and radiation dose data corresponding to the above-mentioned conditions exist, the corresponding metadata and radiation dose data are derived and recorded in the radiation exposure management history of the user's radiation dose information DB (S506, S509 ).

On the other hand, when the requested metadata is not searched for in the secondary search, the radiation dose information DB is searched for tertiary based only on the essential metadata (S507).

In order to derive the radiation dose data corresponding to the user's exposure situation only with the minimum requirement, DB search is performed with the essential metadata except for the option metadata.

As a result of the third search, if the matching data exists, the corresponding data can be utilized as the user's radiation dose management information according to the user setting such as the minimum value, the maximum value, or the average value of the radiation dose data corresponding to the required essential metadata S508, S509).

In this manner, the process of retrieving data corresponding to the user's exposed situation on the basis of the radiation dose information DB is repeatedly performed more than three times, while preventing the missing of the radiation dose data corresponding to the user's radiation exposure situation, Information of other users can be utilized.

By managing personal radiation management details based on the radiation dose information DB, it is possible to update the radiation dose information DB by summing the radiation dose data and the cumulative dose of radiation exposure up to the present time in the specific situation of the present or past users (S510) .

Further, it may be determined whether the user's accumulated radiation dose data falls within a preset safety standard, and an information providing service related to a warning message or radioactivity may be performed according to the degree of deviation from the safety standard range (S511, S512).

The method of estimating the radiation exposure dose illustrated in FIG. 5 can be applied to the following cases. For example, when a user is exposed to radiation during radiographic image capturing but missing radiation exposure dose data at the time of radiographing, the EMR information of the medical institution where the user was treated by the past user is retrieved based on the radiation dose information DB, and the retrieved EMR It is possible to derive the radiation dose data from the information of the past own imaging information recording.

As another example, even if the occupant on the airplane enters the date of boarding and boarding airplane information into the integrated radiation management system, even if the occupant does not directly transmit the irradiated radiation exposure information during flight using the portable radiation measuring device, From the radiation dose information DB, the radiation dose data corresponding to the date of the flight and the airplane information, and store the data in the radiation dose management record of the passenger. At this time, the radiation dose during boarding of the airplane stored in the radiation dose information DB may be data measured by a portable radiometer or the data of research surveyed by other passengers on the same conditions.

In addition, the method of estimating the radiation exposure dose illustrated in FIG. 5 can be applied in case the user is exposed to future radiation. For example, the user can access the radiation dose information database in advance and predict the amount of exposure radiation that meets the requirements before the user is exposed to the radiation exposure, thereby managing the total exposure dose affecting the individual user.

The personalized radiation dose information DB according to the embodiment of the present invention can provide various services in cooperation with various systems in a medical institution system such as Hospital Information System (HIS) or PACS.

FIG. 6 is a diagram showing an example of a system configuration when a personalized radiation dose information DB according to an embodiment of the present invention is utilized in a medical institution.

6, the radiation integrated management system 610 according to the present invention can manage the radiation dose data by interlocking the radiation dose information DB 611 and the EMR DB 621 of the medical institution system 620. For example, in conjunction with the EMR DB 621, it is possible to collect radiation dose data from the patient's past EMR information in the past medical procedure.

In addition, the radiation integrated management system 610 may provide a variety of services related to exposure to radiation in cooperation with an information management system such as a hospital information system (HIS) 622 or a PACS 623 in the medical institution system 620 . For example, when medical image information is to be photographed, the medical institution system 620 may take into account the cumulative radioactivity exposure provided by the integrated radiation management system 610 to induce the patient to a different modality without radiation exposure, The optimal area dose depending on the condition can be recommended. In addition, if there are various imaging medical devices in the medical device, the patient who is exposed to the radiation dose can be firstly introduced to the low dose device.

If the radiation dose of the individual exceeds the preset safety recommendation, adjust the number of shots in the basic imaging guide (eg, within the readable range), or adjust the cumulative radiation exposure information of the individual Can be utilized in the operation of the medical device.

In addition, the radiation integrated management system 610 can provide a route guidance service for avoiding a hazardous area in a hospital to a patient having a radiation dose level as illustrated in FIG. 7, in conjunction with the HIS 622, It is possible to provide additional information service for reduction.

FIG. 7 is a view showing an example of enhancing the intra-hospital route guidance service based on the individual radiation dose information.

Referring to FIG. 7, when the medical institution enters the hospital with the cumulative radiation dose of the patient reaching the danger level (S701) using the radiation dose information of the patient, the radiation integrated management system detects the radiation exposure area (S702), which is a safety-based route (S704) for avoiding a dangerous area exposed to radiation other than a route (S703) through an area where there is a risk of radiation exposure in the hospital through the HIS (S705).

Furthermore, as the individual cumulative radiation exposure information DB according to the embodiment of the present invention is continuously managed, it is possible to provide various radiation related services based on the user state. For example, an airline with a high potential for exposure to natural radiation can provide a service that recommends safe travel routes or overseas travel destinations by utilizing individual radiation dose information. Another example is the use of a personalized radiation dose information database to limit the fetal CT scan, which is optional for pregnant women, and provide lifestyle information such as food and exercise that is effective for radiation exposure to users who are at risk of cumulative radiation exposure. Service can be created.

The foregoing description is merely illustrative of the technical idea of the present invention, and various changes and modifications may be made by those skilled in the art without departing from the essential characteristics of the present invention. Therefore, the embodiments of the present invention are not intended to limit the scope of the present invention but to limit the scope of the present invention. The scope of protection of the present invention should be construed according to the following claims, and all technical ideas within the scope of equivalents thereof should be construed as being included in the scope of the present invention.
