Disclosed is a scanning system for determining a health-condition based on scanning an intraoral object. More specifically, the present disclosure is related to different methods of providing the health-condition, for example by adapting the scanner with different scanning modes.

Method and apparatus embodiments can generate a volume fluorescence image of a tooth. Method and apparatus embodiments can project structured light patterns onto a tooth and generate a contour (volume) image of the tooth surface from acquired corresponding structured light projection images; then acquire one or more fluorescence images of the tooth generated under blue-UV illumination. A composite image that shows fluorescence image content mapped to the generated contour image can be transmitted, stored, modified and/or displayed.

An oral cavity scanning device is provided in the invention. The oral cavity scanning device includes an image capturing unit, an IMU circuit and a processing unit. The image capturing unit obtains a first image and a second image. The IMU circuit obtains IMU information corresponding to the first image and the second image. The processing unit obtains a distance value between the first image and the second image. The processing unit uses a contour algorithm to obtain a first contour and a second contour. The processing unit obtains first sampling points according to the first contour and second sampling points according to the second contour. The processing unit uses a feature algorithm to find relative feature points between the first sampling points and the second sampling points. The processing unit uses a depth information algorithm to obtain the depth information of each feature point.

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.

A method for monitoring the positioning of the teeth including production of a three-dimensional digital initial reference model of the arches of the patient and, for each tooth, definition, from the initial reference model, of a three-dimensional digital reference tooth model; acquisition of updated image of at least one two-dimensional image of the arches in actual acquisition conditions; analysis of each updated image and production, for each updated image, of an updated map; optionally, determination, for each updated image, of rough virtual acquisition conditions approximating the actual acquisition conditions; searching, for each updated image, for a final reference model corresponding to the positioning of the teeth during the acquisition of the updated image, for each tooth model, comparison of the positionings of the tooth model in the initial reference model and in the reference model obtained at the end of the preceding steps to determine the movement of the teeth

A pharmaceutical composition for treating an influenza virus infectious disease, containing an anti-influenza virus agent as an active ingredient is provided. The anti-influenza virus agent is administered to a patient determined to be positive for the influenza virus infectious disease based on an intraoral image captured using an intraoral imaging apparatus.

A method for detecting demineralization of a tooth substance, including the steps of irradiating (S101) a structured light pattern onto the tooth substance; detecting (S102) a light intensity of the light pattern remitted from the volume of the tooth substance; and determining (S103) demineralization of the tooth substance based on the detected light intensity.

A system for imaging and examination of a cervix, comprising a control module connectable with a changeable head configured to image the cervix and collect a tissue biopsy, the head selected from a group consisting of a digital colposcope module, a transvaginal optical probe module and an endo-cervical endoscope module. The system may additionally comprise light source(s) to illuminate cervix tissue; sensing device(s) to generate signal(s) from light and/or to acquire image(s) of a portion of a cervix; and processor(s) in communication with the sensing device(s). The system is configured to: (i) analyze the signal(s); (ii) detect the size of the cervix; (iii) determine parameters defining properties of the cervix; (iv) determine and distinguish normal tissue from abnormal tissue within the cervix; (v) determine the location of area(s) of abnormal tissue in the cervix; and (vi) generate a panoramic view of the cervix.

An intraoral measurement device includes: a device main body that holds a base end side of a prism by a housing, the housing accommodating an illumination member and an imaging member, a cover member that is attached to the device main body in a state of covering, with a space part interposed in between, a distal end side of the prism arranged to face a measurement target, in which a part arranged to face the measurement target is formed by a light transmission window; and a heat transfer member that extends from the device main body along a non-optical surface of the prism, and transfers heat of the device main body to the light transmission window through abutment of a protruding end provided to protrude from the prism against the light transmission window of the cover member.

A dental and facial imaging device includes an adjustable arm, an image sensor mounted on a first end of the adjustable arm and an adjustable patient positioning arm mounted on a second end of the adjustable arm. A distance between the adjustable patient positioning arm and the image sensor is adjustable based on an adjustable length of the adjustable arm. A position indicator scale of the adjustable arm includes multiple notches for calibrating the distance between the adjustable patient positioning arm and the image sensor. The adjustable patient positioning arm includes a patient teeth supporting device and a patient chin rest which are positioned at a fixed coordinate reference relative to the image sensor to capture an image of a patient's teeth. The fixed coordinate reference corresponds to co-ordinates of multiple anatomical planes associated with the patient teeth supporting device and a patient chin rest relative to the image sensor.
