Description

  The present invention relates to a radiographic image detector, a radiographic imaging apparatus, and a radiographic image diagnostic system for obtaining a radiographic image used for diagnostic purposes, and is used in the industrial field of radiographic diagnosis in medicine.

  Conventionally, as a method for obtaining a radiographic image, a so-called screen film system (SF system) in which a fluorescent intensifying screen and a radiographic film are combined is used for radiographic image formation. In this SF system, when radiation such as X-rays transmitted through the subject is incident on the fluorescent intensifying screen, the phosphor contained in the fluorescent intensifying screen absorbs the radiation energy and emits fluorescence. By this light emission, the radiographic film superposed so as to be in close contact with the fluorescent intensifying screen is exposed, and a radiographic image is formed on the radiographic film.

  However, in the SF system, it is necessary to perform imaging while matching the sensitivity areas of the radiographic film used for imaging and the fluorescent intensifying screen. In addition, chemical development and fixing must be performed on the radiographic film, and it takes time until a radiographic image is obtained. It is not preferable.

  In addition, the SF system is an analog image, and in order to perform remote diagnosis using a digital network system, an operation of converting an image signal of a radiographic image obtained by the SF system into a digital signal is required.

  For this reason, in recent radiographic imaging systems, instead of the SF system, digital radiographic images such as computed radiography (CR), which is a digital X-ray diagnostic imaging apparatus, and flat panel type radiation detector (FPD) are used. Systems have been introduced that obtain radiographic images by extracting electrical signals. In such a system, since no radiation film is used unlike the SF system, there is no complicated process such as development processing, and radiation is quickly displayed on the screen of an image display device, for example, a screen such as a cathode ray tube or a liquid crystal display panel. You can draw an image.

  In the field of medical image diagnosis, digital radiological image detection means such as a computed tomography apparatus (CT) and a nuclear magnetic resonance tomography apparatus (MRI) have been used in recent years. By placing it on, remote diagnosis can be easily performed.

The radiologist looks at the irradiation card on which the subject information such as the subject's name and ID and the imaging request are written, calls the patient, confirms it, and inputs these information. For subject information, enter name, ID number, date of birth, gender, chart number, name of doctor in charge, disease name, etc. Recently, the viewpoint of improving the efficiency of input work or preventing erroneous input From the above, a method of reading a magnetic card by an information input unit, an input method using a barcode (for example, Patent Document 1 and Patent Document 2), and a network linked to a hospital information system called HIS were used. An input method or an input method combining an information input unit and a network is also possible.

  Thus, the information input means 351 which inputs body specific information to a radiographic image diagnosis system, and the display means 350 which displays body specific information are provided. The information input unit 351 includes at least one of a camera and a scanner. For example, the information input unit 351 captures the face and pupil of a subject who is a patient with the camera, and uses the face and pupil image as ID information to the control unit 306. The image is registered, and a fingerprint is registered in the control unit 306 as ID information with a scanner.

  Before the radiographic image of the patient who is the patient is captured, the body-specific information of the patient who is the patient is displayed in the ID information on the display unit 350. For example, when the camera captures the face and pupil of the subject who is a patient and registers the face and pupil images as ID information in the control unit 306, the face and pupil images are displayed, and the scanner uses the scanner. When the fingerprint image is registered in the control unit 306 as ID information, the fingerprint is displayed.

  In this way, by displaying the body-specific information of the subject on the display unit 350, the body-specific information displayed by the doctor or the subject can be compared with the subject, thereby confirming that the subject You can eliminate mistakes with others. Since this body-specific information includes at least one of a face, a pupil, and a fingerprint, a doctor or a subject can easily and reliably confirm the subject.

  Further, the information input means 351 inputs the body-specific information of the subject, and collates the input body-specific information with the body-specific information in the ID information of the subject previously stored in the control unit 306. By displaying the collation result on the display means 350, the subject person can be confirmed.

  When the doctor confirms the body-specific information, face information is preferable. When collating information, all information can be used.

  In the above embodiment, body-specific information obtained by a camera or scanner provided in a radiographic image detector or radiographic imaging apparatus is used, but a controller such as a terminal for patient ID registration in another place in advance Etc. (not shown), face information, etc., among ID information input in advance may be displayed on the display unit.

  The present invention compares the body-specific information displayed by the doctor, the subject, and the like with the subject, and can confirm that the subject is the subject, and is used in the industrial field of radiological image diagnosis in medicine. The present invention can be applied to obtaining a radiographic image used for the purpose.
