Abstract
The present invention relates to an apparatus and a method of acquiring an image for dental diagnosis. More particularly, the present invention relates to an apparatus and a method of acquiring a near-infrared image for dental diagnosis, wherein an image for dental diagnosis is acquired using near-infrared radiation and a general image camera rather than using X-rays.
Claims9
An apparatus for acquiring a near-infrared image for dental diagnosis, the apparatus comprising:
- a dental diagnosis module inserted into a patient's mouth, the dental diagnosis module including a near-infrared light source that is placed along a teeth arrangement in an inner side of the patient's teeth and radiates near-infrared radiation in an outward direction of the patient's mouth;
- an optical camera placed in front of a patient's face to photograph the mouth, the optical camera photographing the near-infrared radiation that is radiated from the near-infrared light source and penetrates toward outside of the patient's mouth, and outputting the near-infrared image;
- a display unit displaying information as at least one among text, a graphic, and an image;
- a processor configured to
- generate a near-infrared teeth arrangement image from the near-infrared image, which is inputted from the optical camera,
- measure a twist of the teeth and periodontium from the near-infrared teeth arrangement image,
- generate a teeth arrangement image including information on the measured twist, and
- control the display unit to display the near-infrared teeth arrangement image and the teeth arrangement image.

A method of acquiring a near-infrared image for dental diagnosis, the method comprising:
- a dental diagnosis module driving process in which a dental diagnosis module inserted into a patient's mouth is driven and a near-infrared light source placed along a teeth arrangement in an inner side of the patient's teeth is driven to radiate near-infrared radiation;
- a near-infrared image acquisition process in which an optical camera placed in front of a patient's face is driven to photograph the near-infrared radiation that is radiated from the inner side of patient's teeth and penetrates, and the near-infrared image is output;
- a dental image acquisition process in which a near-infrared teeth arrangement image is generated from the near-infrared image and is output;
- and
- a teeth/periodontium twist information generation step in which the near-infrared teeth arrangement image is analyzed to measure a twist of the teeth and periodontium and a near-infrared teeth arrangement image containing teeth and periodontium twist information having a measured twist value of the teeth and the periodontium is generated and is output.
