Description

  The present invention relates to a technique for processing incidental information relating to a medical image.

  The medical image diagnostic apparatus is an apparatus for imaging and examining / diagnosis information of tissues in a subject such as a fluoroscopic image, a tomographic image, and a blood flow in the subject. The medical image diagnostic apparatus includes an X-ray diagnostic apparatus, an X-ray CT (Computed Tomography) apparatus, an MRI (Magnetic Resonance Imaging) apparatus, an ultrasonic diagnostic apparatus, and an ultrasonic diagnostic apparatus. There are various modalities of medical image diagnosis such as NM (Nuclear Medicine).

  Examination is performed by these medical image diagnostic apparatuses, and tissue information in the subject is imaged as a moving image or a still image to generate a medical image. The medical image is reproduced in real time or the stored image is reproduced and viewed, for example, examination / diagnosis of a disease is performed. The inspector views the image and reports the inspection.

  Conventionally, a medical image viewer selects and displays one of these items based on information such as a patient ID, a patient name, and an examination date from the examination list screen as shown in FIG. Diagnosis based on FIG. 7 is a schematic diagram of an examination list in which stored medical images are displayed in a list for each examination. FIG. 8 is a schematic diagram of an ultrasonic image showing an example of a medical image.

  As shown in FIG. 8, information in the body of the subject is displayed in the approximate center of the screen. For example, diagnosis or the like is performed while viewing the tomographic image 400 as in this screen. In addition to the tomographic image 400, the viewer can view detailed information on the subject such as the height and weight of the subject not displayed on the tomographic image 400, comments such as the health condition reported in advance, information on the examination, etc. It may be necessary to execute diagnosis or the like with reference to FIG.

  Further, in the medical image diagnostic apparatus, the subject is generally inspected after the subject's height / weight, comments, etc. are confirmed by an inspector before starting to acquire information in the subject. It is.

  Conventionally, information shown in addition to an image showing information in the subject (for example, the tomographic image 400 in FIG. 8) is displayed in the accompanying information display column 101 at the top of the ultrasonic image as shown in FIG. Only additional information was displayed. Since this supplementary information was displayed together with the image in the subject, the display space is limited, and subject identification information such as patient ID, patient name, examination date, gender, hospital name, and slight patient information Was only displayed.

  Similarly, in the examination list shown in FIG. 7, a display space is limited for convenience of list display, and therefore a lot of information cannot be displayed. Therefore, only the information for specifying the examination to be browsed such as the patient ID, the patient name, and the examination date is displayed.

  When DICOM (Digital Imaging and Communications in Medicine) is used as a network standard for a medical image management system, the identification information is tag information (DICOM) according to the standard for a medical image managed as a DICOM image. tag).

  Conventionally, in an ultrasonic diagnostic apparatus that records a moving image as a medical image on a VCR tape, a technique has been proposed in which identification information can be confirmed even when the recorded moving image is fast-forwarded and rewound (for example, Patent Document 1). . That is, the inspector can record the display screen data of the identification information by inspecting while operating the switching button (call key), thereby displaying the moving image at high speed like fast forward and rewind. In addition, the presence of the identification information display screen can be confirmed.

JP-A-3-49742

  In the conventional medical image diagnostic apparatus including the ultrasonic diagnostic apparatus disclosed in Patent Document 1, the viewer is not limited to the image inside the subject (for example, the ultrasonic image as shown in FIG. 8) and the identification information of the subject. If you want to confirm the subject's supplementary information (patient information), the name of the doctor who requested the examination, information on the disease, etc., such as comments about the subject's height, weight, health status, etc., refer to that information In order to do so, for example, it has been necessary to perform complicated operations such as analyzing data and preparing and referencing other materials.

  Also, when browsing medical images recorded by a medical image diagnostic apparatus, it is compatible with the viewer (viewer / image display apparatus, terminal, etc.) standard and the medical image management system network standard for the medical image diagnostic apparatus. Otherwise, the identification information added as tag information may not be browsed.

  In addition, if the detailed information on the subject or examination is displayed in the examination list as shown in FIG. 7 for searching the recorded medical image, there is no space, so it is necessary to browse while sliding the screen. It is complicated.

  Further, in the invention of Patent Document 1, it is necessary to perform a switching operation while operating a switching button (calling key), which is complicated and may hinder the inspection work of the inspector. In addition, when the examination work is complicated, it is difficult to perform the switching operation, and it becomes difficult to record display screen data of identification information such as a patient ID. In that case, necessary information cannot be recorded, and there is a possibility that the operation such as diagnosis of the viewer of the medical image may be hindered.

  The present invention has been made in view of the above problems, and its purpose is to add extra functions to a medical image display device and to require extra operations when browsing recorded medical images. Instead, the object is to provide a technique capable of easily and easily confirming information necessary for browsing medical images in detail. It is another object of the present invention to provide a technique that enables the necessary supplementary information to be confirmed when a medical image is browsed even if there is a difference in the medical image management standard regarding the handling of the supplementary information.

The medical image diagnostic apparatus embodiment includes a supplementary information image generating unit, and in-vivo image generating unit, and an information processing unit. The incidental information image generation means acquires incidental information including at least one of information regarding the subject and information regarding examination of the subject, and generates an incidental information image based on the incidental information. The in-vivo image generation means generates an in-vivo image based on the in-vivo information indicating the tissue in the subject for the subject related to the accompanying information acquired by the accompanying information image generation means. The information processing means performs information processing for reducing each of the in-vivo image and the accompanying information image and generating a first reduced image corresponding to the in-vivo image and a second reduced image corresponding to the accompanying information image.

  When the incidental information configuration unit 20 completes the generation of the incidental information image data on the incidental information display screen 200, the incidental information image data is transmitted to the information processing unit 60. This transmission is performed after the incidental information display screen 200 is confirmed by the inspector. For example, the generation of the incidental information display screen 200 is completed, and the inspector performs an operation of completing confirmation of the incidental information displayed via an operation unit (not shown), and the control unit 2 is terminated by the operation. On the basis of receiving the signal, the incidental information image data that has been generated is transmitted to the information processing unit 60.

  Alternatively, the control unit 2 determines for each item whether or not the collection of the incidental information image data has been completed, and if the determination by the control unit 2 determines that the configuration process of the incidental information image data has been completed, the determination is made. The supplementary information image data that has been generated based on the information may be transmitted to the information processing unit 60.

  Further, in the present embodiment, after the incidental information image data relating to the completed incidental information display screen 200 is transmitted to the information processing unit 60, the ultrasonic image unit 3 and the ultrasonic probe 40 described later operate.

(Configuration of ultrasound image part)
Next, the ultrasonic image unit 3 and the ultrasonic probe 40 will be described with reference to FIGS. 1 and 3. FIG. 3 is a schematic diagram showing an ultrasonic image display screen 300 in the ultrasonic diagnostic apparatus 1 according to the embodiment of the present invention.

  As shown in FIG. 1, the ultrasound image unit 3 (corresponding to an example of a part of “image generation means”) is configured by a transmission / reception unit 30 and an image configuration unit 50. The ultrasonic image unit 3 starts operating in conjunction with the information processing unit 60 receiving the supplementary information image data, and the inspection is started. In the ultrasound image unit 3, when the examiner examines the subject with the ultrasound probe 40, the reflected wave received from the subject is converted into a signal, and data relating to the in-vivo image inside the subject based on the signal. That is, ultrasonic image data used for displaying an ultrasonic image is configured.

  In the ultrasonic image unit 3, first, a rate pulse with a delay time is supplied to the pulser of the transmission / reception unit 30, and the pulser transmits a drive signal to the ultrasonic transducer of the ultrasonic probe 40. Upon receiving the drive signal, the ultrasonic transducer converts the signal into an ultrasonic pulse, and transmits the ultrasonic pulse to the examination site of the subject (patient) to be examined. The ultrasonic transducer receives a reflected wave from the body tissue of the subject with respect to the transmitted ultrasonic pulse, converts it into an electrical signal, and transmits the electrical signal to the transmission / reception unit 30.

  When the transmission / reception unit 30 receives an electrical signal applied to the reflected wave from the ultrasonic transducer of the ultrasonic probe 40, the transmission / reception unit 30 converts the electric signal into a digital signal, gives a delay time, performs phasing addition, and transmits to the image construction unit 50.

  The image construction unit 50 performs signal processing (B-mode processing, Doppler processing, etc.) on the signal received from the transmission / reception unit 30. For example, DSC (digital scan conversion) processing is performed and converted into an image signal sequence. In addition, volume rendering is performed on volume data to generate 3D in-vivo information, or MPR processing (Multi Planar Reconstruction) is performed to generate in-vivo information (MPR image data) of an arbitrary cross section. .

  This in-vivo information is assigned to screen data. That is, the image construction unit 50 reads screen data for displaying a background image, a frame, and the like from the storage unit 70 among the data for representing the ultrasonic image display area 304 shown in FIG. The in-vivo information sequentially collected is assigned to the read screen data, and an ultrasonic image for each frame is generated.

  In this way, when the image construction unit 50 generates ultrasonic image data relating to the ultrasonic image for each frame shown in the ultrasonic image display area 304 as shown in FIG. 3, the image construction unit 50 creates the ultrasonic image data.

Information processing is performed so that a reduced image of the image is displayed.

  The information processing unit 60 performs information processing so that an ultrasonic image corresponding to the selected reduced image (305/306) and the accompanying information display screen 200 are displayed in the ultrasonic image display area 304, Review image data used for display on the ultrasonic image display screen 300 shown in FIG. 3 is generated.

  In addition, when the generation of the review image data related to the ultrasonic image display screen 300 in the examination is completed, the information processing unit 60 stores the review image data in the storage unit 70 or outputs the review image data to the printing unit 80 and the display unit 90. . Further, the review image data may be output to a server 100 such as a PACS (Picture Archiving and Communication System).

  In this way, the information processing unit 60 performs processing so that the supplementary information display screen 200 is displayed (or printed) before the ultrasonic image, so that the interpreter of the ultrasonic image related to the examination has the identification information, Interpretation and diagnosis can be performed after confirming incidental information such as patient information and examination information, and it is possible to contribute to improvement of diagnosis certainty.

  In addition, by performing information processing so that incidental information images such as identification information, patient information, and examination information are independent of the ultrasound image (the incidental information display screen 200) and a series of images, the incidental information is converted into an image. It is possible to store, display, print, and the like. As a result, even if there is a difference in the network standard (DICOM, etc.) of the medical image management system between the medical image diagnostic apparatus and the viewer (viewer) or the like, the examination information, patient information, etc. Detailed incidental information can be easily browsed. Further, since the incidental information is imaged as the incidental information display screen 200, it is not necessary to provide a special function for the display device in order to view detailed incidental information in the examination.

  In addition, since the incidental information is captured in the ultrasound image display screen 300 as one image and the screen is generated, there is no problem with the display space of the incidental information. Therefore, the details of the identification information, patient information, and examination information are more detailed. Many can be displayed.
