Description

  The present invention provides a common output format of test result information (medical data) on a subject obtained by a plurality of medical image diagnostic apparatuses (modalities) such as an ultrasonic diagnostic apparatus requested by a medical institution. The present invention relates to a medical report system and a medical data conversion program for realizing the above.

  Conventionally, medical image diagnostic apparatuses have various modalities such as an X-ray diagnostic apparatus, an X-ray CT apparatus, a magnetic resonance imaging apparatus, a nuclear medicine apparatus, and an ultrasonic diagnostic apparatus.

  The doctor appropriately selects these devices according to the medical condition of the patient, and performs diagnosis based on the medical image acquired by the selected diagnostic device.

  In addition, depending on the patient's symptoms, not only one modality, but also multiple modalities are used for examination, and medical images between each modality are compared for comprehensive diagnosis. Is doing.

  For example, a single patient is examined with an X-ray CT apparatus, and further examined with a magnetic resonance imaging apparatus. Based on both medical images, X-ray fluoroscopy and imaging are performed with a cardiovascular X-ray examination apparatus. Surgery is performed.

  Thus, by making a diagnosis while comparing medical images obtained by a plurality of different modalities, it is possible to quickly diagnose a patient's symptom and to greatly improve examination efficiency.

  A system for comprehensive diagnosis and treatment using medical images obtained by a plurality of different modalities in this way includes an X-ray CT apparatus, a magnetic resonance imaging apparatus, an ultrasonic diagnostic apparatus, a circulatory X-ray examination apparatus, and the like. This is realized by connecting a medical image archiving server for capturing medical images from these medical image diagnostic apparatuses and a medical image viewer for displaying medical images captured by the medical image archiving server to a high-speed network.

  In order to improve the efficiency of such various operations, in recent years, a hospital information system (HIS) that electronically manages medical information and a medical image management system (Picture Archive Communication) that manages medical images. System (PACS), Radiology Information System (RIS) that manages examination information in the radiology department, etc. have been introduced, and inspection technicians etc. can interpret the inspection results and create and manage inspection reports. In order to assist, a medical information management system has been established.

  In addition, as a standard protocol for communication of medical images via such a high-speed network (including the definition of an output format when transmitting examination result information), a medical image communication protocol (DICOM: Digital Imaging and Communication in) is used. Medicine) exists.

  This medical image communication protocol (DICOM) is used to connect different types of modalities of different manufacturers (vendors) inside and outside a hospital, and connect them to each other via a network or a medical image storage medium. The purpose is to realize the exchange of data and the transmission of medical image data.

  In a medical image management system using DICOM, generally, medical data (test result information) acquired by a plurality of modalities via a network is sent to a report server, and the report server controls and stores the medical data. It is managed so as to be used for requests of each modality and medical terminal (viewer device etc.).

  Therefore, by connecting the various devices to each other via a high-speed network according to the purpose of medical treatment, there is a shortage of storage space, loss of film, and slowness, which are problems of medical image diagnosis systems centered on conventional films. Overcoming problems such as delivery, it has become possible to enjoy the added value of new medical image diagnosis such as medical image processing, computer-aided diagnosis, and comprehensive medical image diagnosis (for example, see Patent Document 1).

  By the way, in medical institutions such as hospitals, modalities, for example, inspection result information for examination of medical images obtained by an ultrasonic diagnostic apparatus are generally standardized and output in “Structured Reporting” in the DICOM standard. It has become to. This “Structured Reporting” is a report having a frame structure such as site (position), findings, interpretation, disease name / treatment.

  However, because this DICOM standard establishes the report standard step by step and the measurement function of each vendor and each modality cannot always be expressed, the inspection by the measurement function unique to each vendor and each modality. As for result (measurement result) information, hospitals and other medical institutions often record test result information in a report server in an original output format (format) such as an XML format.

  Since the output format defined by each vendor and modality is not the DICOM format, the inspection result information defined in the original output format is often different from the inspection result information defined in the DICOM standard.

  For example, a typical measurement result of left ventricle measurement, “Septal thickness of the ventilatory in end disaster”, is defined as “Interventional Sept. It is defined by the abbreviation “IVSTD”.

  In recent years, examples have been introduced by vendors with different modalities into existing systems that share medical information such as so-called HIS and RIS, which have been widely used for accounting, examination reservations, drug prescriptions, meal management, etc. There are many situations.

Even when test result information defined in a specific output format is output, it is stored in the output format common to the report server, and can always be referred to as appropriate medical data.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a block diagram showing a configuration in an embodiment of a medical report system according to the present invention. As shown in FIG. 1, modalities 101, 102, and 103 are ultrasonic diagnostic apparatuses connected to a hospital LAN 50, and the output formats defined in the test result information output from the modalities 101, 102, and 103 are different.

  For example, the output format defined in the inspection result information output from the modality 103 is an output format by DICOM, and the output format defined in the inspection result information output from the modality 101 is a vendor based on the output format by DICOM. A is an output format uniquely defined, and an output format defined in the inspection result information output from the modality 102 is an XML output format.

  In other words, the “output format defined by vendor A based on the DICOM output format” and the “XML output format” are defined in the medical data output from one modality in this claim. Corresponds to "Format".

  In the present embodiment, the output format defined in the test result information output from each modality and stored in the report server 10 will be described as “output format by DICOM”. Corresponding to "Output Format"

  Hereinafter, the “output format defined in the medical data output from one modality” will be referred to as “unique format”, and the “common output format” will be described as “common format”.

  As shown in FIG. 1, a medical report system according to the present invention includes a plurality of modalities 101, 102, 103, a report server 10 that accumulates test result information output from these modalities 101, 102, 103, and a doctor. And a viewer device 30 as a terminal used by a laboratory technician or the like to refer to examination result information stored in a report server is connected to a network via a hospital LAN 50.

  The report server 10 receives the test result information transmitted from the modalities 101, 102, 103 and the storage means 12 for storing the test result information transmitted from the modalities 101, 102, 103 and the viewer via the hospital LAN 50. And a control unit 11 that transmits the inspection result information in the storage unit 12 to the viewer device 30 based on information input by an input unit (not shown) of the apparatus 30.

  In the medical report system according to the present invention, the “unique format” of the examination result information (medical data) output from the modalities 101, 102, 103 is analyzed, and the outputted examination result information (medical data) is analyzed. When the “unique format” is different from the “common format”, the conversion device 20 that converts the “unique format” of the test result information (medical data) into the “common format” and outputs it to the report server 10 is the hospital. It is provided between the internal LAN 50 and the report server 10. For example, the test result information transmitted from the modalities 101, 102, 103 has an identifier identifying the “unique format” in the header. The modality 101, 102, 103 is provided with identifier adding means for adding this identifier.

  The conversion device 20 includes a control unit 21 and a storage unit 22. The storage means 22 stores in advance a conversion table 221 for converting the inspection result information identifier defined in the “unique format” and the inspection result information identifier defined in the “common format”. . Specifically, an identifier of each unique format and conversion information for converting each unique format into a common format are described.

  The control means 21 refers to the header of the inspection result information output from the modalities 101, 102, 103, and identifies (identifies) the type of the unique format based on the identifier attached to the header; A determination unit that determines whether or not the type of the unique format defined in the inspection result information identified (identified) by the identification unit 211 is the same as the “common format”, and the “specific format” is determined by the determination unit. Is determined to be different from the “common format”, the inspection result information defined in the “unique format” is converted into inspection result information defined in the “common format” with reference to the conversion table 221. A conversion unit 213 and a function of storing the converted inspection result information in the storage unit 22.

  For example, according to the setting of the present embodiment described above, the inspection result information output from the modality 101 is identified as “an output format uniquely defined by the vendor A” by the identification unit 211 that refers to the header, and is output from the modality 102. The output inspection result information is identified as “an output format defined in XML” by the identification unit 211 that refers to the header, and the inspection result information output from the modality 103 is the identification unit 211 that refers to the header. Is specified as “output format defined by DICOM”. Of these, the determination means 212 determines that “conversion of the output format” is necessary for the inspection result information output from the modality 101 and the inspection result information output from the modality 102, and these inspection results The conversion unit 213 is instructed to convert the information output format.

  Upon receiving the conversion instruction, the conversion unit 213 receives the inspection result information output from the modality 101 from the conversion information stored in the conversion table 221 based on the identifier specified by the identification unit 211. A search is made for conversion information in which “an output format defined by vendor A” and “an output format defined by DICOM” are associated with each other, and inspection result information output from modality 101 is “defined by DICOM. It is converted into test result information in “output format”. On the other hand, with respect to the inspection result information output from the modality 102, “output format defined in XML” is selected from the conversion information stored in the conversion table 221 based on the identifier specified by the identification unit 211. And “output format defined by DICOM” are searched for, and the inspection result information output from the modality 102 is converted into inspection result information of “output format defined by DICOM”.

  Note that the test result information output from the modality 103 is determined to be the same as the “common format” by the determination unit 212, so the determination unit 212 notifies the conversion unit 213 of the output format of the test result information. The inspection result information is stored in the storage unit 22 by the control unit 21 without instructing conversion.

  Note that the viewer device 30 has an input means (not shown) for requesting inspection result information to be referred to the report server 10 and a post-conversion output (transmitted) from the report server 10 in response to the request. It has a display device (not shown) for displaying the inspection result information (defined in “common format”).

  Next, the operation of the medical report system configured as described above will be described below with reference to FIGS. FIG. 2 is a sequence diagram showing an operational relationship among the modality, the conversion device, and the report server in the present embodiment.

  As shown in FIG. 1 and FIG. 2, first, as a result of the examination of the patient in each modality 101, 102, 103, the obtained examination result information about the patient is the modality 101, 102, The data is defined and output (transmitted) in a format unique to each of them, and is received by the control means 21 of the conversion device 20 (step S1).

(Identification step)
Next, the identification unit 211 refers to the identifier attached to the header of the received inspection result information, and specifies the output format defined in the inspection result information (step S2).

  The output format (“unique format”) specified at this time is, for example, an output format defined by vendor A based on an output format based on DICOM, an output format based on XML, an output format based on DICOM, or the like.

(Judgment step)
When the output format (“unique format”) defined in the test result information output to the conversion device 20 is identified, the determination unit 212 outputs the identified “unique format” that requires conversion. It is determined whether or not the format.

  For example, when the “common format” stored in the report server 10 is an output format by DICOM, the determination unit 212 is specified by the identification unit 211 referring to the header of the inspection result information output from a certain modality. It is determined whether the output format (“unique format”) is the same output format as the “common format” or a different output format.

  Therefore, if the output format “unique format” of the test result information output from a certain modality is an output format different from the “common format” stored in the report server 10, the determination unit 212 converts the output format. (Step S3-Yes), the conversion unit 213 that has received the determination reads the conversion table 221 from the storage unit 22, and obtains the inspection result information defined in “unique format”. It converts into inspection result information defined by “common format (DICOM)” (step S4).

(Conversion step)
The “output format conversion (step S4)” will be described below with a specific example. 3 to 5 show an example of the test result information in the embodiment of the medical report system according to the present invention. FIG. 3 is defined in the output format in DICOM format output from the modality 101. FIG. 4 shows an example of the inspection result information output from the modality 102. FIG. 5 shows an example of the inspection result information defined by the vendor A based on DICOM. FIG. An example of inspection result information defined in an XML output format is shown.

  In this description, all of FIGS. 3 to 5 show the inspection result information about the measurement result of BSA (Body Surface Area). Further, in the description contents of the inspection result information shown in each figure, a portion surrounded by a frame is a portion to be converted in each output format.

(Conversion method when “unique format” is an output format by DICOM)
First, when the inspection result information is output to the conversion device 20 from the modality 101 that outputs the inspection result information in the DICOM output format, the control means 21 is defined by the inspection result information (see FIG. 3) to be determined. Since the identification unit 211 identifies that the “unique format” is the same DICOM output format as the “common format”, the conversion device 20 is instructed to convert the inspection result information output from the modality 101. The test result information is output to the report server 10 without any problem.

  The report server 10 that has received the inspection result information stores the inspection result information in the “common format (output format by DICOM)” in the storage unit 12 by the control unit 11.

  Hereinafter, the inspection result information defined in the DICOM output format shown in FIG. 3 will be described as a reference example of the “common format”.

(Conversion method when the “unique format” is an output format uniquely defined by the vendor based on DICOM)
First, when the inspection result information is output to the conversion device 20 from the modality 102 that outputs the inspection result information in an output format uniquely defined by the vendor based on DICOM, first, the identification unit 211 causes the “vendor based on DICOM” 4 is identified as “a uniquely defined output format”, the control means 21 makes “CONTAINS” of (0040, a010) the inspection result information itself for the description contents of the inspection result information shown in FIG. Get.

  Next, “02010003” set in the conversion table 221 is searched based on the identification result by the identification unit 211. At this time, if the identifier “02010003” is included in the container, the value “2.21” is obtained from (0040, a30a) numeric value in the description content of the inspection result information shown in FIG.

  Next, the control means 21 creates a container similar to the inspection result information defined in the DICOM output format shown in FIG. 3 as the “common format”. Note that when creating this container, the value of (0040, a030a) is not included at this time.

  And the control means 21 sets said "2.21" to the value of the blank (0040, a030a).

At this time, according to the description of the inspection result information defined in the output format by DICOM shown in FIG. 3 as “common format”, “m ² ” is set as the standard unit of BSA (“0040,08ea” In the description contents of the test result information shown in FIG. 4, “cm ² ” is set as the standard unit of BSA (“0008,0100” below “0040,08ea”). Therefore, the conversion unit 213 converts the value “2.21” according to the conversion table 221 even when the unit is changed from “cm ² ” to “m ² ”.

(Conversion method when “unique format” is an output format defined in XML)
First, when the inspection result information is output to the conversion device 20 from the modality 101 that outputs the inspection result information in an output format defined in XML, as shown in FIG. 5, the control means 21 first measures the BSA. The head address of XML data that is a cluster of test result information about the result is specified.

  Next, in the conversion table, “TusStudyCommentBSA Value”, which is set in an original term (original word) related to the output format defined in XML, is searched from the top address of the XML data.

  When the identifier “TusStudyCommentBSA Value” is included in the XML data, numerical data “2.00” is obtained.

  Next, the control means 21 creates a container similar to the inspection result information defined in the DICOM output format shown in FIG. 3 as the “common format”. Note that when creating this container, the value of (0040, a030a) is not included at this time.

  And the control means 21 sets said "2.00" to the value of the blank (0040, a030a).

Thereafter, according to the description of the inspection result information defined in the DICOM output format shown in FIG. 3 as “common format”, “m ² ” is set as the standard unit of BSA (subordinate to “0040,08ea”) If the BSA standard unit is not “m ² ” in the description content of the test result information shown in FIG. 5, the conversion means 213 sets the value “2.00”. Conversion is performed according to the conversion table 221.

(Output step)
The control means 21 having obtained the inspection result information defined in the “common format” as described above outputs the inspection result information to the report server 10 (step S5).

(Save step)
And the control means 11 which received the test result information defined by "common format" from the converter 20 memorize | stores the said test result information in the memory | storage means 12 (step S6), and is completed.

  In this way, the examination result information defined in the “common format” stored in the storage means 12 is the examination result that the doctor or examination engineer wants to refer to using the input means (not shown) of the viewer device 30. A request for information is made, and inspection result information is transmitted from the report server 10 in response to the request, and can be confirmed on a display device (not shown).

  The medical data conversion program according to the present invention is configured by configuring the operation of the medical report system described above as a program. In the embodiment, the control unit 21 includes an identification step, a determination step, a conversion step, and an output step. The storage step is executed by the control means 11.
