1 is a diagram schematically illustrating a system in which a gateway device according to an embodiment of the present invention is used.

As shown in FIG. 1 , a gateway device 2 according to an embodiment of the present invention is connected to a Picture Archiving Communications System (PACS) 1 . PACS is a medical imaging information system that is currently widely used in hospitals.

The gateway device 2 is communicatively connected to the PACS 1 . To this end, the gateway device 2 may be directly connected to a server of the PACS 1 or a computer system in which the PACS 1 is driven through a communication cable, or may be connected to a communication network connected to the PACS 1 by wire or wirelessly. .

In this embodiment, the PACS 1 is described as an example of a medical image information system, but the gateway device 2 according to an embodiment of the present invention is capable of communicating with other medical image information systems other than the PACS 1 . It can also be used in conjunction.

As shown in FIG. 1 , the gateway device 2 is configured to communicate with the analysis server 3 .

The analysis server 3 may exist in a remote location outside the hospital, and in this case, the gateway device 2 may communicate with the analysis server 3 through a wired or wireless remote communication network. For example, the gateway device 2 and the analysis server 3 may be connected via a wide area network such as the Internet.

Alternatively, the analysis server 3 may be located in a hospital operating the PACS (1). In this case, the gateway device 2 may be communicatively connected to the analysis server 3 through a wired/wireless communication network in the hospital.

The analysis server 3 detects a lesion by reading a medical image captured using a medical imaging device such as X-ray, computer tomography (CT), magnetic resonance imaging (MRI), or the like. The analysis server 3 may be configured to read a medical image based on artificial intelligence (AI) and detect a lesion, and the analysis server 3 may be configured to capture a medical image (head, chest, abdomen, A separate analysis algorithm divided according to the spine, hand, foot, etc.) and the type of lesion to be detected (fracture, nodule, etc.) may be provided.

2 is a block diagram schematically illustrating a configuration of a gateway device according to an embodiment of the present invention.

As shown in FIG. 2 , the gateway device 2 according to an embodiment of the present invention includes a medical image information receiving unit 21 , a filtering unit 22 , a verification unit 23 , a de-identification unit 24 , and storage. It includes a unit 25 , a medical image information transmitting unit 26 , an analysis information receiving unit 27 , a re-identification unit 28 , an analysis information transmitting unit 29 , and a notification unit 30 .

Medical image information receiving unit 21 , filtering unit 22 , verification unit 23 , de-identification unit 24 , storage unit 25 , medical image information transmitting unit 26 , analysis information receiving unit 27 , re-identification The communication unit 28 , the analysis information transmitting unit 29 , and the notification unit 30 are functionally classified, and may differ from the actual physical configuration of the gateway device 2 . For example, the medical image information receiving unit 21, the medical image information transmitting unit 26, the analysis information receiving unit 27, the analysis information transmitting unit 29, and the notification unit 30 may be executed by one communication device, The filtering unit 22 , the verification unit 23 , the de-identification unit 24 , and the re-identification unit 28 may also be executed by one processing unit.

The medical image information receiver 21 receives medical image information stored in the PACS 1 or generated by a medical imaging apparatus associated with the PACS 1 from the PACS 1 . The medical image information may be a DICOM (Digital Imaging Communication in Medicine) file, which is currently standardized medical image information.

FIG. 3 is a diagram schematically illustrating a configuration of a DYCOM file transmitted from the PACS of FIG. 1 to a gateway device, and FIG. 4 is a diagram illustrating one CT image set included in the DYCOM image information of FIG. 3 .

The DYCOM file 10 is composed of header information 11 and image information 12 .

In the header information 11, various types of information about the image information 12 are recorded. For example, the header information 11 includes patient information 11a, image-related information 11b, and equipment information on which an image is captured.

The patient information 11a may include information for specifying the patient, such as the patient's name, ID, date of birth, age, and gender. The patient ID may be the patient's resident registration number, a patient code assigned by the hospital, or the like.

The image-related information 11b may include information on an image number, an image type, a photographing region, and the like. The image number is a sequence number assigned to an image generated by a medical imaging device that takes multiple images, such as CT, and the image type is information that distinguishes an X-ray image, a CT image, an MRI image, an ultrasound image, etc. The photographed portion is information about photographed body parts such as the head, chest, and abdomen.

The image information 12 includes an image actually captured by the medical imaging apparatus. For example, when an X-ray imaging apparatus is used, an X-ray image, and when a CT imaging apparatus is used, a CT image is included in the image information 12 .

As shown in FIG. 4 , in the case of a CT image, a plurality of images is configured as one set 12a, and a serial number is assigned to each image and stored in the image information 12 . For example, when the CT imaging apparatus captures 360 images, one set of images 12a to which serial numbers from 1 to 360 are respectively assigned in the image information 12 are stored.

The filtering unit 22 determines the suitability of analysis of the medical image information 10 received by the medical image information receiving unit 21 from the PACS 1 .

Analysis suitability may be determined based on a type of an image included in the medical image information 10 , a photographing region, and the like. In order for the gateway device 2 to select and transmit only the medical image information that matches the analysis field of the analysis server 3 that transmits the medical image information, the filtering unit 22 selects the image included in the medical image information 10 . The suitability of analysis is judged based on the type and area to be photographed. Analysis suitability may mean whether the medical image information 10 corresponds to a specialized analysis field of the analysis server 3 .

That is, when the analysis server 3 has a specialized algorithm for finding nodules by analyzing the CT image of the lungs, the filtering unit 22 controls the image among the medical image information 10 received by the medical image information receiving unit 21 . Medical image information whose type is a CT image and the imaging site is chest or lung is classified as medical image information for which analysis suitability is recognized, and other medical image information is classified as medical image information for which analysis suitability is not recognized.

To this end, the filtering unit 22 determines analysis suitability based on the image-related information 11b recorded in the header information 11 of the medical image information 10 . That is, information on an image type and a photographing part may be checked among the image-related information 11b, and analysis suitability may be determined based on the information.

Alternatively, the filtering unit 22 may be configured to determine analysis suitability based on the image information 12 of the medical image information 10 . That is, the type of the image and the photographing part may be determined based on the photographed image, and analysis suitability may be determined according to the determination result. In this case, the filtering unit 22 may be configured to determine the type of image and the photographing part based on the image information 12 through an image processing algorithm or an artificial intelligence algorithm. In this case, there is an advantage in that analysis suitability can be accurately determined even when the image-related information 11b of the header information 11 is incorrectly written due to a recorder's mistake. When the image-related information 11b described in the header information 11 and the type of image determined by the filtering unit 22 and the photographing site are different from each other, the filtering unit 22 sends the header information 11 to the notification unit 30. Information that there may be a defect may be transmitted, and the notification unit 30 may transmit a notification message to the manager of the hospital and/or the manager of the gateway device and/or the manager of the analysis server 3 .

The verification unit 23 verifies the integrity of the medical image information 10 received by the medical image information receiving unit 21 .

To this end, the verification unit 23 is configured to determine the type of image, the photographing part, etc. based on the image information 12 through an image processing algorithm or artificial intelligence algorithm, and the type of image confirmed through the actual image, photographing The integrity of the medical image information 10 may be verified by checking whether the image-related information 11b recorded in the header information 11 matches the region and the like.

Also, the verification unit 23 may be configured to determine whether the image set 12b included in the medical image information 10 is missing. As described above, in the medical image information including the image information 12 in which a plurality of images are composed of one set 12b, serial numbers of images constituting each set 12b are recorded in the header information 11 . The verifier 23 may verify the integrity of the medical image information 10 by examining serial numbers of images recorded in the header information 11 and checking whether some of the images are missing.

When the verification unit 23 confirms that a defect exists in the medical image information 10 , the verification unit 23 may transmit information that a defect may exist in the medical image information 10 to the notification unit 30 , , the notification unit 30 may transmit a notification message to the manager of the hospital and/or the manager of the gateway device and/or the manager of the analysis server 3 .

Although the configuration in which the medical image information receiving unit 21 and the filtering unit 22 are connected and the filtering unit 22 and the verifying unit 23 are connected may be described in FIG. 2 , the medical image information receiving unit 21 is filtered. The unit 22 and the verification unit 23 may be connected to each other, and the medical image information receiving unit 21 performs the filtering unit 22 and the verification unit 23 simultaneously to check the integrity and analysis suitability of the medical image information 10 , respectively. can judge

The de-identification unit 24 converts at least a part of the patient information 11a recorded in the header information 11 into de-identification information.

The patient information 11a includes unique identification information and non-unique identification information. The unique identification information is information that does not overlap with other patients, and the non-unique identification information is information that may overlap with other patients. For example, a patient's ID is unique identification information because it cannot be duplicated with other patients, and a name, date of birth, age, or gender is non-unique identification information because it is information that can be duplicated with other patients.

The de-identification unit 24 may convert unique identification information among the patient information 11a into de-identification information.

FIG. 5 is a diagram schematically illustrating a configuration of a non-identification DICOM file converted by the de-identification unit of FIG. 2 .

As shown in FIG. 5 , the de-identification unit 24 may convert the patient ID, which is unique identification information, into a universal unique identifier (UUID), which is a type of non-identification information. In addition, the non-unique identification information may be converted into useless information. Unused information refers to random numbers or information composed of random numbers and/or characters that have no meaning. According to an embodiment, the de-identification unit 24 may delete non-unique identification information. Therefore, the header information 11' of the de-identification daicom file 10' converted by the de-identification unit 24 is unidentified patient information ( 11a'), or the unique identification information includes de-identified patient information in which only un-identified UUIDs exist.

When there are two or more pieces of unique identification information in the patient information 11a, the de-identification unit 24 may convert only one of the unique identification information into a UUID, and the remaining unique identification information may be converted or deleted into useless information. Since unique identification information can specify a patient with only one piece of information, only one piece of unique identification information can specify a patient. Even if changed or deleted, the converted UUID can be re-identified to specify a patient.

6 is a table of corresponding information stored in the storage unit of FIG. 2 .

As shown in FIG. 6 , the de-identification unit 24 transmits, to the storage unit 25, correspondence information including the correspondence between the unique identification information (patient ID) of each patient and the de-identified UUID to the storage unit 25, and stores it. The unit 25 may store the corresponding information transmitted from the de-identification unit 24 . This is to restore the UUID to unique identification information in the re-identification unit 28, which will be described later.

According to an embodiment, the de-identification unit 24 may convert the unique identification information into the de-identification information by using a function in which the unique identification information and the non-identification information correspond one-to-one.

Meanwhile, the de-identification unit 24 may add identification information 11c' of a hospital operating the PACS 1 connected to the gateway device 2 to the header information 11'. This is to deliver the analysis information to the hospital when the analysis server 3 analyzes the medical image information 10 ′ transmitted from several hospitals.

According to an embodiment, the de-identification unit 24 may include the hospital identification information 11c' in the de-identification information. In this case, the de-identification information includes identification information 11c' of the hospital together with information de-identifying the patient's unique identification information.

The medical image information transmitter 26 transmits the medical image information 10 ′ in which the unique identification information is de-identified through the de-identification unit 24 to the analysis server 3 . The storage unit 25 may record and store schematic information and a delivery time of the medical image information 10 ′ transmitted by the medical image information transmitter 26 to the analysis server 3 .

When the gateway device 2 is communicatively connected to a plurality of analysis servers 3 specialized in different analysis fields, the medical image information transmitting unit 26 analyzes the medical image information 10 ′ according to the photographed region or image type. The medical image information 10 ′ may be transmitted to the analysis server 3 suitable for . In this case, the medical image information transmitting unit 26 selects the analysis server 3 suitable for analysis based on the header information 11 ′, or the filtering unit 22 determines the analysis suitability in the header information 11 . A suitable analysis server 3 can be selected and transmitted based on the recording.

When the transmission of the medical image information 10 ′ fails, the medical image information transmitter 26 may transmit information indicating that the transmission of the medical image information 10 ′ has failed to the notification unit 30 , and the notification unit 30 . ) may transmit a notification message to the manager of the hospital and/or the manager of the gateway device and/or the manager of the analysis server 3 .

The analysis information receiving unit 27 receives analysis information from the analysis server 3 . The analysis information is information including an analysis result analyzed by the analysis server 3 on the medical image information 10'. The analysis server 3 reads a lesion existing in the image information 12 based on the header information 11 ′ and the image information 12 of the medical image information 10 ′. For example, the analysis server 3 reads the presence, size, location, state, etc. of the lung nodule based on the CT image of the lung, and transmits the reading result to the analysis information receiving unit 27, where the analysis information receiving unit ( The information that 27) receives from the analysis server 3 is analysis information.

The analysis information may be delivered in the format of a daicom file.

For example, the analysis information may be converted image information into an image in which the location and description of the lesion are engraved on the image, or the reading result may be recorded in header information.

The analysis information may be medical image information in which header information and/or image information is added to the read result, or information that does not include the image information 12 and includes only the read result and information for re-identification. In the latter case, it is possible to reduce the communication load between the gateway device 2 and the analysis server 3 .

The analysis information receiving unit 27 may check whether the received analysis information is normal, and transmit the analysis information to the re-identification unit 28 if there is no defect in the analysis information.

If the reception of the analysis information fails or there is a defect in the analysis information, the analysis information receiving unit 27 may transmit information that the reception of the analysis information has failed to the notification unit 30 , and the notification unit 30 is the hospital's A notification message may be sent to the administrator and/or the administrator of the gateway device and/or the administrator of the analysis server 3 .

Meanwhile, the re-identification unit 28 restores and re-identifies the de-identification information included in the received analysis information.

The re-identification unit 28 may restore the unique identification information converted into the de-identification information by the de-identification unit 24 . To this end, the re-identification unit 28 may restore the unique identification information converted into the de-identification information by the de-identification unit 24 based on the corresponding information stored in the storage unit 25 . Alternatively, when the de-identification unit 24 converts the unique identification information into the de-identification information using a function, an inverse function is applied to convert the de-identification information into the unique identification information.

If the re-identification fails, the re-identification unit 28 may transmit information that the restoration of the unique identification information has failed to the notification unit 30, and the notification unit 30 is a hospital manager and/or gateway device. A notification message may be sent to the administrator and/or the administrator of the analysis server 3 .

The re-identification unit 28 transmits the analysis information from which the unique identification information is restored to the analysis information transmission unit 29, and the analysis information transmission unit 29 transmits the analysis information transmitted from the re-identification unit 28 to the PACS (1). send. In this embodiment, the description is based on the fact that the analysis information transmitting unit 29 transmits the analysis information back to the medical image information system 1 that transmits the medical image information to the medical image receiving unit 21 . Accordingly, the analysis information transmitter 29 may transmit the analysis information to a medical image information system other than the medical image information system 1 that has transmitted the medical image information to the medical image receiver 21 . For example, when a hospital operates a plurality of medical image information systems separated from each other, the medical image information system that transmits medical image information to the medical image receiver 21 and the analysis information are received from the analysis information transmitter 29 . The medical image information systems used may be different from each other.

When it fails to transmit the analysis information to the PACS 1 , the analysis information transmitting unit 29 may transmit information that the transmission of the analysis information has failed to the notification unit 30 , and the notification unit 30 is the manager of the hospital and/or a notification message may be sent to the administrator of the gateway device and/or the administrator of the analysis server 3 .

The notification unit 30 continuously checks the communication status between the gateway device 2 and the PACS 1 and the communication status between the gateway device 2 and the analysis server 3, and if the communication status is poor, the hospital A notification message may be sent to the manager of the , and/or the manager of the gateway device and/or the manager of the analysis server 3 .

Since the medical image information 10 is transmitted outside the hospital through the gateway device 2 , the patient's personal information must be de-identified. Accordingly, the gateway device 2 according to the present embodiment converts unique identification information among the patient's personal information 11a included in the medical image information 10 into de-identification information, and converts the remaining information into useless information or After deletion, since it is transmitted to the analysis server 3, the patient's personal information is not exposed to the outside.

7 is a diagram for explaining a function of a gateway device according to an embodiment of the present invention.

When a medical image of a patient is captured, and the PACS 1 records and stores the DICOM file 10 , which is medical image information, the PACS 1 transmits the DYCOM file 10 to the gateway device 2 ( S11 ).

The medical image information receiving unit 21 of the gateway device 2 receives the DYCOM file 10 transmitted from the PACS 1 , and the filtering unit 22 and the verifying unit 23 receive the DYCOM file 10 . Analysis suitability and integrity are checked (S12).

When the analysis suitability and integrity of the daicom file 10 are recognized, the de-identification unit 24 selects at least one of unique identification information among the patient information 11a included in the header information 11 of the daicom file 10 . A de-identification operation of converting the non-identifying information into non-identifying information, and converting or deleting the remaining information among the patient information 11a into obsolete information to generate the non-identifying DYCOM file 10' (S13).

Thereafter, the medical image information transmitting unit 26 transmits the de-identified DICOM file 10' to the analysis server 3 (S14).

The analysis server 3 receives the non-identified dycom file 10' and performs an analysis of reading the lesion based on it (S15).

Thereafter, the analysis server 3 transmits the analysis information generated in the format of the daicom file to the gateway device 2 (S16).

The analysis information receiving unit 27 of the gateway device 2 receives the analysis information, and the re-identification unit 28 performs a re-identification operation of restoring de-identification information included in the received analysis information to unique identification information. do (S17).

Thereafter, the analysis information transmitter 29 of the gateway device 2 transmits the analysis information in which the unique identification information is restored to the PACS 1 .

Since the analysis information transmitted to the PACS (1) is in the format of a daicom file, the information is added to the existing daicom file 10 without additional conversion, and the analysis information in a state in which the unique identification information is restored is converted to the PACS ( 1), so analysis information can be accurately added to the patient's daicom file.

Those of ordinary skill in the art to which the present invention pertains will understand that the present invention may be embodied in other specific forms without changing the technical spirit or essential features thereof.
