Description

  The present invention relates to an image display taken by a medical X-ray imaging apparatus capable of displaying an image in real time, and an X-ray imaging provided with a control mechanism for determining whether or not to display an image taken in an imaging room. Relates to the device.

  In recent years, an X-ray detector such as a flat panel detector (hereinafter simply referred to as an FPD) made of a semiconductor element is used instead of an X-ray film or an imaging plate used in an X-ray imaging apparatus. What is recorded as typical image data is known.

An X-ray imaging apparatus using an FPD or the like can display a captured image on an image display unit in real time, unlike an apparatus conventionally used in a hospital or the like using a film or an imaging plate.
This type of X-ray imaging apparatus can display a captured image in real time, and can be provided with an image display apparatus in the imaging room so that the availability of imaging can be observed immediately. reference).

JP-A-8-46869

In an X-ray imaging system that can display images in real time, the X-ray imaging image is displayed on the image display unit in the examination room or the image display unit of the X-ray holding device immediately after imaging to confirm the success or failure of the X-ray imaging. On the other hand, there is a possibility that the patient who is the subject himself / herself sees the captured image on the spot.
If the patient has a serious illness such as cancer, it is mentally preferable to know the medical condition such as cancer by looking at the X-ray image displayed on the image display unit before the appropriate explanation by the doctor. In some cases, it is necessary to prevent the patient from seeing the X-ray image immediately after the X-ray image.

  In order to solve the above-described problems, the present invention is a medical X-ray imaging apparatus that can display an image in real time and has at least one image display unit installed in an imaging room. A sensor for discriminating is provided, a mechanism for controlling the display of the X-ray image is controlled by a signal of the sensor, and a mechanism for displaying the X-ray image and stopping the image display is provided.

  A sensor such as a pressure sensor, a distance meter, an RF tag, or the like is used as a sensor for detecting whether the patient is present at the imaging position.

  Instead of the detection sensor, the image display may be terminated when a predetermined time has elapsed after the end of X-ray imaging.

  Even if an X-ray image is displayed on an image display unit installed in the same examination room immediately after X-ray imaging, the patient can be prevented from seeing the X-ray image.

It is a figure which shows the outline | summary of the X-ray imaging apparatus by the Example of this invention. It is a flowchart which shows the implementation method of this invention. It is the schematic which shows the modification Example of this invention. It is the schematic which shows another modified example of this invention.

  DESCRIPTION OF EMBODIMENTS Embodiments for carrying out the present invention will be described with reference to the drawings.

  As shown in FIG. 1, the X-ray imaging apparatus of the present invention includes an X-ray tube holding device 2 that holds an X-ray tube, and an X-ray imaging table 5 or an X-ray imaging stand 6 that performs standing imaging, Alternatively, both are arranged in one examination room R, and the X-ray tube device 1 and the X-ray detector 8 such as an FPD are arranged opposite to each other with the patient 10 placed on the X-ray imaging table 5 interposed therebetween.

  FIG. 2 is a flowchart showing this embodiment. When an X-ray is irradiated from the X-ray tube apparatus 1 to the patient 10 as the subject within an irradiation range limited by the X-ray movable diaphragm 3 (step 1 and steps are abbreviated as S), the X-ray detector 8 outputs The X-ray detection data to be processed is processed by a data processing unit (not shown) to generate an X-ray image (two-dimensional digital X-ray image) corresponding to the X-ray image area, and the generated X-ray image Is displayed (S2) on the examination room image display unit 4 and the X-ray tube holding device control panel 11.

  Similarly, when the patient is in a standing position, the X-ray tube apparatus 1 and an X-ray detector 12 such as an FPD are arranged opposite to each other with the patient 10 in front of the X-ray imaging stand 6 interposed therebetween. When X-rays are exposed from the X-ray tube apparatus 1 to the patient 10 as the subject (S1), the X-ray detection data output from the X-ray detector 8 is processed by the data processing unit to form an X-ray imaging region. A corresponding X-ray image is created, and the created X-ray image is displayed on the image display unit 4 or the X-ray tube holding device control panel 11 (S2).

  In the X-ray imaging apparatus according to the first invention, there is a pressure sensor 7 installed under the top plate of the X-ray imaging table 5, and a pressure change is detected when the patient gets on the X-ray imaging table 5. In the case of standing-up imaging, the signal of the mat sensor 9 installed at the lower part of the patient's standing position is detected.

  It is detected from the detected signal whether the subject patient 10 is at the imaging position (S3), and if the patient is present at that location, the image display is continued (S4). When it is detected that the user has not moved to the place, the X-ray image display on the image display unit 4 or the X-ray tube holding device control panel 11 is stopped (S5).

  The pressure sensor 7 may be a mat sensor or a non-contact sensor placed on the top plate of the X-ray imaging table 5.

  As a patient detection sensor used to determine whether a patient is present at the imaging position, any sensor such as a pressure detection method, a capacitance change method, a photoelectric sensor, a human sensing pyroelectric sensor, etc. may be used. good. Further, instead of the sensor, a mechanism may be provided that stops the image display after a lapse of a predetermined time until the patient can move and view the display image after the X-ray imaging is completed.

  The X-ray imaging apparatus of the second invention is installed, for example, in front of the X-ray movable diaphragm 3 as a patient detection sensor used for determining whether the patient of the first invention exists at the imaging position, as shown in FIG. A distance meter 21 using an ultrasonic wave, a laser, or the like for measuring the distance from the focal point of the X-ray tube apparatus 1 to the surface of the patient 10 is provided.

  When the distance information L1 measured by the distance meter 21 during X-ray imaging changes suddenly as indicated by L2 after the X-ray imaging is completed, it is determined that the subject patient 10 has moved from the imaging position, and the image display unit 4 or X The display of the X-ray image on the tube holding device control panel 11 is stopped.

  Centralized management of data input and output by mobile terminals at the place where medical practice is conducted, and it is possible to grasp medical practice information in real time and to facilitate medical work smoothly. It has been proposed to attach an RF tag (wireless IC tag).

  As shown in FIG. 4, the X-ray imaging apparatus according to the third invention uses an RF tag (wireless IC tag) 31 as a patient detection sensor used for determining whether the patient according to the first invention is present at the imaging position. When the change of the signal of the receiver 32 installed is detected near the X-ray imaging table 5 or the X-ray imaging stand 6 and the change exceeds a certain value, the patient 10 as the subject is at the imaging position. The display of the X-ray image of the image display unit 4 and the X-ray tube holding device control panel 11 is stopped. In addition, what was shown with the same code | symbol in FIG.1, FIG.3, FIG.4 has the same function.

  The present invention is a medical X-ray imaging apparatus capable of displaying an image in real time, and can be applied to an X-ray imaging apparatus having at least one image display unit in an imaging room.
