Description

  The present invention relates to a medical image system, an image inspection apparatus, and a program.

  In recent years, information has been digitized in many medical institutions. For example, an image generation apparatus (modality) such as a CR (Computed Radiography) apparatus, a CT (Computed Tomography) apparatus, or an MRI (Magnetic Resonance Imaging) apparatus attaches incidental information to image data of a medical image obtained by imaging. , DICOM image data conforming to the DICOM (Digital Imaging and Communications in Medicine) standard is generated.

  The modality transmits the DICOM image data to the image detection apparatus. In the imaging apparatus, an imaging operation is performed by a radiographer (an imager). Then, the imaging apparatus transmits DICOM image data to the image server.

  As this imaging apparatus, for example, a medical image is displayed on the display unit, and preset conditions (whether the display time of the medical image is longer than the set time, whether the examination OK button is pressed, etc.) are satisfied. In this case, a technique for transmitting DICOM image data to an image server is disclosed (see Patent Document 1).

The image server stores and manages DICOM image data (transmitted from the imaging device) generated in the modality. When there is a DICOM image data acquisition request from the interpretation terminal, the image server provides the DICOM image data stored and managed. Then, the image interpretation terminal displays a medical image (DICOM image) on the high-definition monitor based on the acquired DICOM image data. The interpretation terminal selects an important image (Key Object Selection Document) to be interpreted from the displayed DICOM images based on the user operation of the interpretation doctor.

  By the way, at the time of the imaging work, the imaging apparatus displays a list of medical images for each examination based on the DICOM image data transmitted from the modality. The radiographer (image examiner) performs image inspection on all images from image number 1 to the end number in units of examination.

  However, in recent years, with the improvement of the modality function, the number of medical images generated in one examination is increasing, and the burden of imaging work by a radiographer (photographer) is increasing.

  For example, when 1000 medical images are taken in one examination, the radiologist (photographer) performs image examination on all the images from image number 1 to image number 1000.

  In addition, medical images to be imaged include an image to be imaged with high accuracy and other images. For example, for a medical image generated in an imaging range to be subjected to comparative interpretation, it is necessary to perform an imaging operation with high accuracy, but for a medical image generated in other imaging ranges, no need to do that.

  However, at present, the radiographer (photographer) cannot know which medical image is generated in the imaging range to be subjected to comparative interpretation, and the medical image generated in the entire imaging range cannot be obtained. On the other hand, the imaging work is performed with the same accuracy.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to reduce the burden of image inspection work by the image examiner.

  Hereinafter, an embodiment of a medical image system according to the present invention will be described with reference to the drawings.

[System configuration of medical imaging system]
FIG. 1 shows a system configuration of the medical image system 100. As shown in FIG. 1, a medical image system 100 includes a RIS (Radiological Information System) 10, a modality 20, an imaging device 30, an image server 40, an image interpretation terminal 50, and a report management server 60. Each device is connected via a communication network N so that data communication is possible.

  The RIS 10 performs information management such as medical appointment reservation, diagnosis result report, results management, and material inventory management in the radiology department. The RIS 10 transmits imaging order information generated in an electronic medical chart system (not shown) to the modality 20.

  The modality 20 is an imaging device that images a patient according to the imaging order information received from the RIS 10 and generates image data of a medical image. Further, the modality 20 generates incidental information related to the image data based on the photographing order information. Then, the modality 20 attaches the accompanying information to the image data (hereinafter referred to as image actual data), generates DICOM image data conforming to the DICOM standard, and transmits the DICOM image data to the imaging device 30. As the modality 20, an imaging apparatus that captures various types of medical images such as a CR apparatus, a CT apparatus, and an MRI apparatus can be applied.

  FIG. 2 shows a data configuration diagram of DICOM image data generated by the modality 20. As described above, DICOM image data is composed of incidental information and actual image data. The incidental information includes patient information, examination information, series information, and image information.

  Patient information is information about a patient, such as patient ID, patient name, date of birth, and sex. The examination information is information relating to the examination such as the examination instance UID that identifies the examination, the examination date, the examination time, the reception number, and the doctor in charge. The series information is information regarding a series (unit) of a series of medical images for each modality generated in one examination, such as a series instance UID that identifies the series, a modality name, an examination part, and a series number. The image information is information related to a medical image such as an SOP instance UID that identifies an image and an image number.

  In addition, one or a plurality of examinations are associated with (related to) one patient. Therefore, there is a one-to-one relationship or a one-to-multiple relationship between patient information and examination information. In addition, one or a plurality of series is associated with (related to) one inspection. Therefore, there is a one-to-one relationship or a one-to-multiple relationship between the inspection information and the series information. In addition, one or more medical images are associated with (related to) one series. Therefore, there is a one-to-one relationship or a one-to-multiple relationship between the series information and the image information.

  Hereinafter, DICOM image data corresponding to one medical image is referred to as a DICOM image data object. For convenience of explanation, the DICOM image data object and the actual image data included in the DICOM image data object may be simply referred to as a DICOM image.

  Returning to FIG. 1, the imaging device 30 displays the medical image (image actual data) generated by the modality 20 and the accompanying information thereof, and the examiner who is the user of the imaging device 30 determines the medical image and the accompanying information. This is for confirmation and correction (image inspection work). When receiving the DICOM image data from the modality 20, the image inspection device 30 displays a medical image (actual image data) and its accompanying information based on the DICOM image data. The image inspection apparatus 30 performs correction of incidental information and image processing of a medical image (gradation processing, addition of annotation data, etc.) based on the user operation of the image examiner. Then, the imaging device 30 transmits the DICOM image data to the image server 40.

  The image server 40 receives the DICOM image data from the image inspection device 30, stores it, and manages it (stores it). That is, the image server 40 receives the DICOM image data generated in the modality 20 via the image detection device 30. When the image server 40 receives a DICOM image data acquisition request from the image interpretation terminal 50, the image server 40 transmits DICOM image data corresponding to the acquisition request to the image interpretation terminal 50.

  The report management server 60 stores and manages (stores and manages) the interpretation report created in the interpretation terminal 50.

  The interpretation terminal 50 is a terminal such as a PC (Personal Computer) that has a monitor that displays a medical image and is installed mainly for the purpose of the interpretation doctor creating an interpretation report of the medical image. The interpretation terminal 50 transmits a DICOM image data acquisition request to the image server 40 based on a user operation by the interpretation doctor, and acquires DICOM image data corresponding to the acquisition request. Then, a medical image is displayed on the monitor based on the DICOM image data. The interpretation terminal 50 selects an important image (hereinafter referred to as a key image) to be interpreted from medical images displayed on the monitor based on a user operation by the interpretation doctor. Then, the image interpretation terminal 50 creates an image interpretation report based on a user operation by the image interpretation doctor and transmits it to the report management server 60. Then, the report management server 60 stores the transmitted interpretation report.

  The image interpretation terminal 50 also generates key image specifying information that specifies a key image (specifies the selected DICOM image). Then, when the image interpretation terminal 50 transmits the created image interpretation report to the report management server 60, the image interpretation terminal 50 transmits an image interpretation completion notification as a notification that the image interpretation has been completed and the key image specifying information to the image server 40. The key image specifying information is the SOP instance UID of the image information included in the DICOM image data object corresponding to the selected key image.

[Functional configuration of image server]

  The storage unit 45 also stores a database program for managing DICOM image data. The DICOM image data stored in the storage unit 45 is managed in cooperation with the database program and the control unit 41.

  FIG. 4 shows a storage management image diagram of DICOM image data stored and managed in the storage unit 45. The DICOM image data object is stored and managed based on patient information, examination information, and series information included in the incidental information. According to FIG. 4, the storage unit 45 stores 1000 DICOM image data objects related to the series X of examination E performed on the patient A (DICOM image data objects d1 to d1000). The storage unit 45 stores key objects related to the series Y of the examination E performed on the patient A.

  Here, the key object stored in the storage unit 45 will be described. When receiving the interpretation completion notification and key image specifying information from the interpretation terminal 50 via the communication unit 44, the control unit 41 generates a key object based on the key image specifying information. Specifically, the control unit 41 generates a key image series Y in addition to the series X related to the inspection E, and generates a key object associated with the series Y. The key object holds the SOP instance UID of the target image. The control unit 41 uses a conversion table or the like to link the DICOM image data object having the corresponding SOP instance UID and the key object (for example, using a pointer to indicate the address where the DICOM image data object is stored) ). Note that the number of key objects is not limited to one, and a plurality of key objects may exist. For example, when five key images are selected in the interpretation terminal 50, the control unit 41 generates five key objects associated with the series Y. The above is the description of the key object.

  Returning to FIG. 3, when the control unit 41 receives a key object acquisition request from the imaging device 30 via the communication unit 44, the control unit 41 transmits the corresponding key object to the imaging device 30. In addition, when the control unit 41 receives a key image acquisition request from the imaging device 30 via the communication unit 44, the control unit 41 transmits a corresponding DICOM image data object (key image) to the imaging device 30.

[Functional structure of image inspection device]
FIG. 5 shows a functional configuration of the image inspection device 30. As shown in FIG. 5, the imaging device 30 includes a control unit 31, an operation unit 32, a display unit 33, a communication unit 34, and a storage unit 35, and each unit is connected by a bus 36.

  The control unit 31 includes a CPU (Central Processing Unit), a RAM (Random Access Memory), and the like, and comprehensively controls the processing operation of each unit of the image detection device 30. Specifically, the CPU reads various processing programs stored in the storage unit 35 in accordance with an operation signal input from the operation unit 32 or an instruction signal received by the communication unit 34, and is formed in the RAM. The work area is expanded and various processes are performed in cooperation with the program.

  The display unit 33 is configured by an LCD (Liquid Crystal Display), and displays various screens based on display data input from the control unit 31.

  The communication unit 34 includes a LAN (Local Area Network) adapter, a router, a TA (Terminal Adapter), and the like, and transmits and receives data to and from external devices such as the modality 20 and the image server 40 connected via the communication network N. I do.

  The storage unit 35 is composed of a hard disk or the like, and stores a control program, parameters and files necessary for executing the program. The storage unit 35 temporarily stores DICOM image data (one or more DICOM image data objects) generated by the modality 20. The DICOM image data is subject to image inspection, and when image inspection is performed, the control unit 31 transmits the DICOM image data to the image server 40 via the communication unit 34. Hereinafter, DICOM image data (DICOM image data object) to be imaged may be referred to as DICOM image data (DICOM image data object) to be imaged.

  When receiving the DICOM image data from the modality 20 via the communication unit 34, the control unit 31 temporarily stores the DICOM image data in the storage unit 35 as the imaging target DICOM image data. Then, the control unit 31 displays the supplementary information and the actual image data of the DICOM image data to be imaged on the display unit 33 for use by the imager. Hereinafter, a process in which the control unit 31 causes the display unit 33 to display supplementary information and actual image data of the DICOM image data to be imaged is referred to as an imaging screen display adjustment process. Details of the image inspection screen display adjustment processing will be described later.

  When the control unit 31 receives an operation signal indicating the completion of the imaging work from the operation unit 32, the imaging target DICOM image data is detected as DICOM image data (imaged DICOM image data). It transmits to the image server 40. Then, the image server 40 stores the examined DICOM image data.

  The control unit 31 generates a key object acquisition request. Then, the control unit 31 transmits the key object acquisition request to the image server 40 via the communication unit 34. Then, the control unit 31 receives a key object corresponding to the key object acquisition request from the image server 40.

  In addition, the control unit 31 generates a key image acquisition request based on the key object. Then, the control unit 31 transmits the key image acquisition request to the image server 40 via the communication unit 34. Then, the control unit 31 receives a DICOM image data object (key image) corresponding to the key image acquisition request from the image server 40.

[Processes performed by the medical imaging system for key object generation]
Next, regarding the key object generation, a specific operation of each device executed in the medical image system 100 will be described with reference to FIG. This processing is executed when the interpretation doctor creates an interpretation report of a medical image in the interpretation terminal 50.

  First, the interpretation terminal 50 transmits a DICOM image data acquisition request to the image server 40 based on a user operation such as an interpretation doctor (step S1). The DICOM image data acquisition request includes data specifying information such as a patient name and an examination date.

  When receiving the DICOM image data acquisition request from the image interpretation terminal 50, the image server 40 transmits the corresponding DICOM image data to the image interpretation terminal 50 based on the data specifying information included in the DICOM image data acquisition request (step S2). Specifically, the image server 40 sets the value of the “examination date” of the data acquisition request among the examination information associated with the patient information having the value of “patient name” that matches the “patient name” of the data acquisition request. All the DICOM image data objects associated with the examination information having the value of “inspection date” that coincides with is transmitted. Hereinafter, according to the example of FIG. 4, the inspection corresponding to the data acquisition request is “inspection E”, and the number of corresponding DICOM image data objects is 1000.

  When receiving the DICOM image data (1000 DICOM image data objects in examination E) from the image server 40, the interpretation terminal 50 displays 1000 medical images (DICOM images) on the monitor based on the DICOM image data ( Step S3). The image interpretation terminal 50 displays 1000 medical images (DICOM images) by scrolling the screen or the like.

  Then, the interpretation terminal 50 selects one or a plurality of key images from 1000 medical images (DICOM images) displayed on the monitor based on a user operation by the interpretation physician (step S4). The interpretation doctor interprets the key image. Then, the image interpretation terminal 50 creates an image interpretation report based on a user operation by the image interpretation doctor, and stores the image interpretation report in the report management server 60 (step S5).

  Then, the image interpretation terminal 50 transmits an image interpretation completion notification, which is a notification that the image interpretation has been completed, and key image identification information, which is information for identifying the key image, to the image server 40 (step S6). Here, the key image specifying information is the SOP instance UID of the image information related to the DICOM image selected as the key image. The interpretation completion notification includes patient information and examination information corresponding to the examination that has been interpreted.

  When the image server 40 receives the interpretation completion notification and the key image identification information from the interpretation terminal 50, the image server 40 generates a key object based on the key image identification information (step S7). Specifically, the image server 40 generates a series Y for key images, and generates a key object associated with the series Y. Here, the image server 40 manages the DICOM image selected by the image interpretation terminal 50 as a key image by generating the key object. The process ends here.

[Processes performed by the medical image system for DICOM image data storage]
Next, with regard to the storage of DICOM image data, specific operations of each device executed in the medical image system 100 will be described with reference to FIG. This process is executed when the imager performs an image inspection operation on the DICOM image data generated by the modality 20 in the image inspection device 30.

  First, the modality 20 captures a patient and generates DICOM image data (step S101). Here, it is assumed that the modality 20 has taken 1000 medical images in this examination (referred to as examination G). That is, the modality 20 has generated 1000 DICOM image data objects in the examination G.

  The modality 20 transmits the generated DICOM image data (1000 DICOM image data objects) to the image detection device 30 (step S102).

  When receiving the DICOM image data from the modality 20, the imaging device 30 temporarily stores the received DICOM image data (1000 DICOM image data objects) in the storage unit 35 as the imaging target DICOM image data (step S103). .

  Then, the image examiner performs a user operation to start the image inspection operation on the image detection target DICOM image data temporarily stored in the storage unit 35 in step S103.

  Then, the image inspection device 30 generates a key object acquisition request in the past inspection under the same conditions as the inspection that generated the image detection target DICOM image data based on the incidental information of the image detection target DICOM image data. An acquisition request is transmitted (step S104). The past examination under the same condition means, for example, a past examination in which “modality name”, “station name”, “examination part”, “examination direction”, “examination posture”, “procedure”, “patient ID”, and combinations thereof are equal. . Items other than these items may be added to the same condition.

  Specifically, the imaging apparatus 30 determines items “modality name”, “station name”, “examination site”, “examination direction”, “examination position”, “procedure”, “patient ID”, and the like from the incidental information of the DICOM image data to be imaged. The key object acquisition request including the item is generated by extraction. Here, the item “modality name” is a type of modality, and takes values such as CR, CT, MR, and the like. The item “station name” is a device name, and takes a different value for each device generation or manufacturer. The item “examination part” is an examination part, and takes values such as the left, right, front, and rear of the head and chest. The item “inspection direction” is a direction in which the image is taken, and takes values such as the front and side surfaces. The item “inspection position” is a photographed position, and takes values such as standing and lying. The item “patient ID” is a patient ID. The items included in the key object acquisition request can be changed as appropriate according to the type of items to be regarded as past inspections under the same conditions.

  When the image server 40 receives the key object acquisition request from the imaging device 30, the image server 40 reads the patient information corresponding to each item included in the key object acquisition request and the key object linked to the examination information from the storage unit 45, and The key object is transmitted to the image inspection device 30 (step S105). If a past examination under the same examination conditions as the examination G is an examination E (see FIG. 4), a key object (see FIG. 4) associated with the series Y associated with the examination E associated with the patient A is read out.

  When receiving the key object from the image server 40, the image inspection device 30 generates a key image acquisition request based on the key object and transmits the key image acquisition request to the image server 40 (step S106). Specifically, the generated key image acquisition request is a request to acquire the DICOM image data object d301 (see FIG. 4) indicated by the key object.

  When receiving the key image acquisition request from the image sensing device 30, the image server 40 reads the DICOM image data object (key image) indicated by the key object from the storage unit 45 and transmits it to the image sensing device 30 (step S107). Specifically, the image server 40 reads the DICOM image data object d301 (see FIG. 4) and transmits it to the imaging device 30.

  When receiving the key image (DICOM image data object d301) from the image server 40, the image inspection device 30 performs an image detection screen display adjustment process (step S108).

  FIG. 8 is a flowchart of the image detection screen display adjustment processing (step S108) performed by the image inspection device 30. As illustrated in FIG. 8, the imaging device 30 extracts an image number included in the image information included in the incidental information of the key image (DICOM image data object indicated by the key object) received from the image server 40 (step S201).

  Then, the image inspection apparatus 30 includes the extracted image number and the extracted image number from the image detection target DICOM image data object group (image detection target DICOM image data generated in the inspection G) temporarily stored in the storage unit 35. The DICOM image data object to be imaged having the same image number is specified (step S202).

  Here, the image number is a number assigned in order from 1 to medical images generated (captured) in one examination. For example, since 1000 medical images are generated in the examination G, image numbers 1 to 1000 are sequentially assigned to the respective medical images. Also, for example, when 1000 slice images of a patient are taken from the top to the bottom (from head to leg), the image number of the top medical image is 1, and the image number of the bottom medical image Is 1000.

  Then, the image inspection device 30 displays the image detection screen 331 on the display unit 33 (step S203). FIG. 9 shows a screen example of the image inspection screen 331. On the image inspection screen 331, medical images (DICOM images) generated in one examination are displayed in an array (list display). Also, DICOM images are arranged in the order of image numbers from the leftmost side of the array. The image inspection screen 331 may be configured to display a two-dimensional array such as 5 rows and 5 columns.

  The imaging device 30 first displays an imaging screen 331 in a state where the DICOM image P301 corresponding to the imaging target DICOM image data object specified in step S202 is arranged at the center of the screen (see FIG. 9A). Further, on this image inspection screen 331, the DICOM image P301 and the 10 DICOM images (P291 to P300, P302 to P311) before and after the DICOM image P301 are marked (enclosed by a frame) (FIG. 9A). ) To (c)). It should be noted that the DICOM image P301 and the ten DICOM images before and after it (P291 to P300, P302 to P311) may be enclosed in different frames as shown in FIG. Also good.

  The user browses 1000 DICOM images by moving the scroll bar b1 to the left and right. FIG. 9B shows an image inspection screen 331 in which the scroll bar b1 is moved to the left. FIG. 9C shows an image inspection screen 331 in which the scroll bar b1 is moved to the right. FIG. 9D shows an image inspection screen 331 in which the screen is scrolled to the leftmost based on a user operation.

  Here, as shown in FIG. 9D, the DICOM image P1 of the image number 1 is usually an image in which no human body is shown. However, such an image is not displayed on the first imaging screen 331 (FIG. 9A).

  In step S203, the image server 40 adds markings to the DICOM image corresponding to the identified DICOM image data object to be identified and the 10 DICOM images before and after the DICOM image data object. Marking an image of 10 percent (100 in this embodiment) of the total number (1000 in this embodiment) displayed on the imaging screen 331, centering on the DICOM image corresponding to the DICOM image data object It is good also as attaching. Further, 10% of the total number of sheets may be compared with 10 sheets before and after, and marking may be applied to the smaller number. In other words, the imaging device 30 adds markings to the DICOM image corresponding to the identified imaging target DICOM image data object and the DICOM image near the DICOM image. Thus, the inspection screen display adjustment process is completed.

  Returning to FIG. 7, when the image inspection screen 331 is displayed in the image inspection screen display adjustment process, the image examiner performs an image inspection operation with reference to the image inspection screen 331. Then, the DICOM image data to be imaged generated in the examination G is subjected to correction of supplementary information and image processing of a medical image (gradation processing, addition of annotation data, etc.), and the DICOM to be imaged. The image data is transmitted to the image server 40 as imaged DICOM image data (step S109).

  When receiving the image-read DICOM image data (1000 DICOM image data objects in the inspection G) from the image-detecting device 30, the image server 40 stores and manages the DICOM image data (step S110). The process ends here.

  As described above, according to the present embodiment, the image inspection device 30 receives the DICOM image generated by the modality 20 and sets the DICOM image as an object to be imaged. Then, the image inspection device 30 acquires a key image from the image server 40 in the past inspection under the same conditions as the inspection that generated the DICOM image to be imaged. Then, the imaging device 30 compares the incidental information attached to the acquired key image with the incidental information attached to the DICOM image to be imaged, and compares the information from the DICOM image to be imaged. A DICOM image corresponding to the acquired key image is specified. Then, the image inspection device 30 displays the specified DICOM image P301 on the first image detection screen 331 (FIG. 9A).

  Therefore, the image examiner can view an important DICOM image at the time of initial display of the image examination screen 331, and can save the trouble of moving the scroll bar b1 to the important DICOM image. In addition, important DICOM images can be known. Therefore, it is possible to reduce the burden of the image inspection work by the image examiner.

  In addition, the image inspection device 30 displays the identified DICOM image P301 on the image detection screen 331 with marking. Therefore, the examiner can know the important DICOM image P301 at a glance, and can further reduce the burden of the image examination work by the examiner.

  Further, the image inspection device 30 adds a marking to the DICOM image (P291 to P300, P302 to P311) near the identified DICOM image P301 and displays the DICOM image on the image detection screen 331. Therefore, the image examiner can know the important DICOM image P301 and the DICOM image in the vicinity thereof, and can improve convenience in the image inspection operation.

  In addition, since the image inspection screen 331 is not configured to display a medical image of image number 1 in which the human body is not captured at the time of initial display, the medical image that does not require an image inspection operation is skipped and the next medical image is displayed. The initial operation is no longer necessary. Therefore, the convenience in the image inspection work can be further enhanced.

  The description in the present embodiment is an example of a medical image system according to the present invention, and the present invention is not limited to this. The detailed configuration and detailed operation of each device constituting the system can be appropriately changed.

  In this embodiment, an example in which a hard disk is used as a computer-readable medium storing a program is disclosed, but the present invention is not limited to this example. As other computer-readable media, a non-volatile memory such as a flash memory and a portable storage medium such as a CD-ROM can be applied. Also, a carrier wave can be applied as a medium for providing program data via a communication line.
