  • the tooth image may be a dental image or a panoramic image taken by an X-ray imaging apparatus.
  • the microscope 2 a conventionally known microscope for dental surgery can be used.
  • the dentist looks directly into the eyepiece part of the microscope and a case where the camera is attached to the eyepiece part side of the microscope.
  • a camera is attached to the microscope 2 for use. An output signal from this camera is output to the image processing apparatus 1.
  • the dentist may look directly into the eyepiece of the microscope or may not use the microscope. In such a case, there is no input signal from the microscope 2 to the image processing apparatus 1.
  • the place where such a detection means 3 is installed may be an arbitrary place such as a wall, a desk, or a dental unit in an examination room of a dental clinic.
  • the detection means 3 may be attached to a patient chair 31, for example.
  • the detection means 3 composed of a reflective sensor is disposed at a position corresponding to the position below the backrest and a position corresponding to the position below the armrest.
  • the detection means 3 may detect the human body (operator) itself, or may detect the position of the foot controller 34, for example. This is because when the surgeon uses the foot controller 34, the foot controller 34 is installed in a range where his / her feet can reach at his / her medical position.
  • the input unit 4 inputs information necessary for control such as processing performed by the image processing apparatus 1 and setting of a tomogram displayed on the display unit 5, and is a device such as a keyboard or a mouse.
  • the display means 5 displays a tooth image or the like, and is, for example, a liquid crystal display.
  • windows, icons, buttons, and the like are displayed by a GUI (Graphical User Interface), and the operator performs an operation of selecting them with the input means 4 such as a mouse. It can be performed.

  • FIG. 4 is a schematic diagram showing an example of a screen displayed in the case of the 9 o'clock position, which is the second position, as an example.
  • the shape of the mark image 50 is not particularly limited as long as it can indicate the medical treatment position of the operator, and may be, for example, a triangle, a quadrangle, a polygon, a circle, an ellipse, or the like.
  • the mark image 50 has the shape of an arrow and is an image showing the line of sight of the operator. That is, the base end portion of the arrow indicates the medical treatment position, and the tip end portion of the arrow indicates the point of the operator's line of sight.
  • the mark image 50 is an image showing the surgeon's line-of-sight direction, the surgeon can intuitively recognize the orientation of the tooth image on which the mark image 50 is superimposed.
  • the tooth image on which the mark image 50 is superimposed may be an image acquired by the microscope 2. That is, the mark image 50 may be superimposed on the microscope image.
  • the mark image 50 may be superimposed on the microscope image.
  • one tooth of the CT image of the tooth is enlarged and displayed with a high-magnification microscope image. Is displayed.
  • a microscope image with a high magnification reduces the field of view of the microscope by the amount of enlargement.
  • FIG. 6C is a schematic diagram in the case where the medical treatment position of the operator D is 12:00 and the image of the sagittal section S (sagittal image) on the tooth of the patient P is referred to.
  • FIG. 6D is a schematic diagram in the case where the medical treatment position of the operator D is 9 o'clock and an image of the axial section A (axial image) and coronal image of the tooth of the patient P is referred to.
  • the orientation of the image to be referred to during the treatment matches the orientation of the tooth actually observed during the treatment. Is less burdensome for image reading and reading errors are less likely to occur.
  • the orientation of the image referred to during the treatment and the orientation of the tooth actually observed during the treatment do not coincide with each other. It is easy to feel a burden in reading the image, and a reading mistake is likely to occur. According to this embodiment, especially in the case of FIG. 6C and FIG. 6D, the effect of preventing the reading error of the tooth image is great.
  • the tooth root appears to be bent to the right on the image. If there is no information such as a mark image, the patient's treatment tooth root tends to be bent to the right, but this image may be an image indicating that this image is bent to the front or back. . In such a case, there is a possibility that the root canal is damaged due to a misunderstanding, for example, when a therapeutic device such as a file is stuck in an unexpected direction.
  • reading the tooth image is supported by displaying the mark image 50 superimposed on the tooth image. Therefore, an operator who performs treatment while checking the tooth image can reduce the burden of reading the tooth image and improve the success rate of the treatment.
  • the reading load is reduced, for example, for example, setting of the medical location of each of a plurality of surgeons.
  • the medical treatment position 25 (see FIG. 1), which is the processing result of the processing means 10, is information in which, for example, information for identifying the surgeon and the medical treatment position of the surgeon are associated with each other.
  • the information for identifying the surgeon may be information that can identify an individual such as a name.
  • the surgeon inputs information for identifying the surgeon.
  • the mark image 50 can be displayed at a position corresponding to each medical treatment position following the change of the operator.
  • the medical care position setting unit 12 sets the medical care position in association with at least one of an operator, a patient, and a treatment type.
  • the arrow-shaped mark image 50 has been described in the example of the screen displayed when the surgeon's medical position is the second position at 9 o'clock.
  • the present invention is not limited to this.

  • FIG. 8 shows a modification of the screen display example of FIG.
  • the orientation of the image (coronal image) displayed in the window 42 is the same as the orientation of the patient that the operator is viewing in front. Therefore, the surgeon's line-of-sight direction may be represented by a white arrow shown in FIG.
  • the arrow-shaped mark image 50 shows the surgeon's line-of-sight direction. The inside is upward.
  • the X-ray image on which the mark image is superimposed and the plurality of teeth are displayed is not limited to the axial image, and may be a coronal image or a sagittal image, for example. Furthermore, it is an image which superimposes a mark image, Comprising: The image of several teeth and dentition is not restricted to a cross-sectional image, A 3D image and CG image may be sufficient.
  • the head mounted display may be a non-transmissive type, for example, so-called VR (Virtual Reality) goggles may be used.
  • the VR goggles allow a user wearing this apparatus to experience VR, AR (Augmented Reality), or MR (Mixed Reality).
  • the VR goggles may be of a type in which a mobile with a camera such as a smartphone is mounted, in addition to a type that includes a camera for photographing the outside world in advance.
  • the VR goggles camera can project the outside view through the camera on the display that the user wearing it observes. According to this, the information acquired from the VR goggles camera and the X-ray image showing the treatment position of the surgeon can be displayed together.
  • the user wearing the head mounted display may be a dental hygienist, a dental assistant, or the like in addition to a dentist.
