Description

  The present invention relates to a system for photographing and displaying an intraoral area.

In the treatment of oral diseases such as dental caries, the hospital visit is often terminated after the intended treatment is completed.
The treatment of caries often starts with awareness of symptoms such as pain and discomfort in the oral cavity, and there are many patterns in which the hospital visit ends when the treatment is completed. If there is not, it is often left as it is, and there are many cases that go to the hospital only after the caries progresses. Treatment after the disease has progressed must be prepared for the suffering suffered by the patient, such as tooth extraction, and the cost burden on the patient will increase as a result.
Also, in such a transient hospital visit, the oral cavity cannot be sounded and there are no subjective symptoms such as dirt, swelling, defects, tartar, wear, salivary stones, malfunctions, etc. There are many cases where the person does not know the symptoms.
Even for the dentistry business, it may be impossible to say that it is profitable to perform treatment on a one-off basis, but there has been no suitable means to solve it.

  In such a temporary treatment, the intraoral camera used in the dental clinic is often used for explanation to the patient when the treatment purpose is clear. There are many unclear parts of the treatment system for this.

JP-A-10-97404

Japanese Patent Application Laid-Open No. 10-97404 shows a configuration of an electronic medical chart that is easy to see from the patient side by displaying all teeth on a computer monitor and coloring each tooth.
The visibility of the dentition is also required for informed consent. However, even if a part of the entire dentition is easy to see, it will be expanded to explain the treatment, and the purpose of the treatment will be understood. Configuration is required.
Many observations in the oral cavity using image display have been proposed, but in the end, the conventional single treatment system is limited to providing information to the patient. It has not reached.

In view of the above, the present invention
Unit imaging means for imaging the oral cavity for each medical improvement unit, setting means for setting medical improvement order information for an image that has been unit-imaged by the unit imaging means, and the medical improvement order information Based on the medical improvement order information, the combination of the display means for displaying the list in a displayable manner and the display medium for displaying and recording the display information obtained by the display means, the patient is aware of treatment. Increase the health of the oral cavity and improve the management efficiency of the dentistry by enabling continuous patient acquisition.
Further, by carrying this display medium by the patient, it is possible to recognize the situation in the oral cavity of the patient and increase the interest in the oral cavity not only for the patient but also for those who do not require treatment.

In the unit imaging means for imaging the oral cavity for each medical improvement unit, the oral cavity indicates a region such as a tooth, a dentition, a gum, an alveolar bone, a lip, a hard palate, a soft palate, and a uvula.
Medical examination includes examination and treatment, and a dentist examines and treatment may be performed at all medical institutions.
Medical care improvement units include caries, periodontal disease, tongue cancer, gingival cancer, etc., preferably one diagnosis and treatment range, dirt, correction, etc., prevention treatment, quasi-medical treatment may also be indicated .
Improvement refers to actions that can be overcome by brushing, fluorine, application of anti-oral breathing agent, preventive measures such as applying fluorine to teeth, cleaning, application of preventive agents such as periodontal disease, etc. It is shown.
Imaging refers to a state in which two-dimensional or three-dimensional display such as a state of being printed / printed on a sheet is performed in addition to image data that can be output and displayed on a computer display or a mobile phone display unit.
The medical improvement order information of the setting means for setting the medical improvement order information for the unit imaged image by the unit imaging means indicates symbols, signs, numerical values, etc. indicating the order of medical care, prevention, and improvement. Any other data that indicates the date and time of medical treatment, the progress of disease, the prediction of disease progression, etc., as long as it can determine the order of medical improvement for at least a plurality of unit images. In addition to the contents that can be visually confirmed, it may be a parameter for calculation that can be confirmed by computer calculation processing.

  “Display so that it can be displayed as a list” means, for example, a state in which unit images are printed and displayed together with medical treatment improvement order information on a sheet, and is composed of one or more sheets, or JPEG, GIF, BMP, etc. The image is displayed based on the style of the display, the page is displayed on the display without any page breaks, etc., but the display status etc. are shown, but at least the medical improvement order is a list, and the whole is easily recognized As long as it is possible, it may be configured by printing on a plurality of sheets, a state in which a plurality of images are scrolled and displayed, and the like.

    The display medium on which the display information obtained by the display means is displayed and recorded is image data based on a state printed or printed on one or more sheets or booklets, or a format such as JPEG, GIF, or BMP. In some cases, the display medium may be a paper or booklet paper medium, a USB memory, an SD card, a display device having a recording element such as a memory, a mobile phone, or the like. There are prints, printed matter, electronic images, etc. that can be carried by at least the patient and see inside the oral cavity. In addition, since it includes the case of browsing own intraoral data on a homepage display on the Internet, the display medium includes a desktop and a notebook personal computer.

In the present invention, it is preferable that all the teeth of the patient's upper jaw and lower jaw are first photographed to form a still image, and a unit image is formed based on the whole tooth image.
The acquisition of all-tooth images is exemplified by, for example, a method of forming by capturing and connecting a still image along a dentition in addition to an intraoral camera using a fish-eye lens and a convex mirror. Is done.
A medical tooth is designated from the obtained whole tooth image, and a still image is formed around the designated tooth.
In this case, it is possible to finish the image processing easily with less burden on the patient, because it is only necessary to copy and enlarge only the corresponding part from the entire tooth image and display it. Is preferable.

You may take a new picture, but you can enlarge the number of pixels of the camera, supplement the color, contour, etc. In such a case, only one shooting is required, so that the explanation time is rational.
Moreover, it may be possible to make a similar cover for a medical site and a medical site that are discovered later by using a computer that performs a clickable link for each tooth by image processing.
Moreover, if the dental teeth are clickable links, it is possible to easily enlarge and display the portions of the whole tooth images by making them three-dimensional.

In addition, the message column is displayed each time a click is made by placing the message, such as rank, scheduled medical start date, seriousness of medical treatment, medical treatment period, medical fee, etc., corresponding to each tooth. In addition, a format in which images arranged in each order are displayed on one screen as much as possible is also possible.
In this case, the number of list displays may be adjusted every time the size of the image is adjusted.
Also, at the same time that all tooth images are acquired, each tooth is automatically subjected to contour extraction work based on software processing, and an area having a predetermined distance from the extraction range is automatically set, and an individual image of each tooth May be formed.

  Alternatively, it is possible to specify a certain range set in advance and specify all teeth with a rough sense. In addition, by visual inspection, data can be specified by graphic software such as range specification and accompanying message input. It may be formed.

  The present invention enables a patient to recognize the situation in his oral cavity by displaying a list of unit images obtained by imaging individual medical treatment sites and medical improvement information at the time of intraoral medical treatment. To ensure the management stability of the dentistry business by enabling the need for medical treatment and improvement, the need for treatment for improvement in the oral cavity, and the continuous treatment for improvement of medical treatment in the oral cavity.

This unit image is displayed on a monitor display that can be seen as a patient, for example. It is a homepage established by a dentist who prints, prints, or stores a medical improvement order information and unit image obtained on a single sheet of paper or stores them on a mobile phone equipped with a storage medium. Display on a personal screen.
The patient always recognizes the situation in the oral cavity and the necessity of medical treatment by the display means, so that the possibility of continuous medical care and improvement for oral health is increased. Management improvements such as improved profitability are also possible.

Next, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1A is a diagram showing an embodiment of the present invention.
Reference numeral 11 denotes intraoral image photographing means, which is a device that obtains digital image data by photographing using, for example, a camera for photographing all teeth of the upper jaw and lower jaw.
The intraoral image photographing means 11 is, for example, a reflection-type dental camera using a convex mirror as shown in FIG. 3C, or another intraoral photographing camera using a fisheye lens, and is a digital image of all teeth. Is output.
Alternatively, as shown in FIG. 6, a method of obtaining each tooth image by photographing each tooth with a normal intraoral camera, extracting the contour from each captured image, and connecting at a common portion of the contour, etc. It may be used.
Reference numeral 12 denotes a medical site detection means for setting, for example, a tooth for medical care or improvement and a predetermined range of the tooth, and a wide range of intraoral images input by the intraoral image photographing means 11. Then, it is cut out and extracted using a graphic software by visual inspection.
Alternatively, the tooth contour is extracted by software processing, and the center of the extracted contour is calculated assuming a circle, and an image having a radius 10% to 20% longer than the contour from the center is obtained. The extracting process and the like are shown.
Moreover, you may add the process of marking to the extracted site | part.

Marking is performed by attaching a conspicuous color to a diagram to be treated on an intraoral image, such as a circle, square, or triangle using general-purpose graphic software, for example, if it is computer processing. The marking may be displayed as an image and may be handled integrally with the data. When the marking is used repeatedly, the marking may be superimposed.
If necessary, for example, a range may be automatically marked with a predetermined range during a designation operation, or a unit image may be automatically displayed. Here, “automatic” refers to software processing, but a dedicated circuit using hardware may be used.

Reference numeral 13 denotes a unit image forming means for processing and forming an image for medical care obtained by the medical site detection means 12 for display, and forming an image to which an area for entering medical order and comments is added. It is for doing.
The unit image forming unit 13 automatically creates and displays a template by designating the medical site by the above-described medical site detection unit 12 by an icon operation by software.
As for the image, only the designated range is projected from the image input by the intraoral image photographing means 11, or the user may designate a separately created unit image display template.
The image may also be captured and displayed by a camera using an appropriate reflecting mirror shown in FIG. 3 when the unit image is displayed. The display may be initially displayed as a moving image in the unit image area, and then confirmed and displayed as a still image by pressing a confirm button.
14 is a medical treatment order setting means, for example, depending on the progress of dental caries and the degree of medical improvement, the dentist arbitrarily or while consulting with the patient, or the progress of caries and the degree of deformation of the caries May be automatically measured to determine the ranking. The automatic rank is determined by digitizing the difference in tooth color and comparing it with a certain threshold value, or when the degree of deformation exceeds a certain level from the basic shape of the tooth, or a spectrum based on the wavelength of the tooth detection wavelength for the illumination light source. The order of the image may be changed on the monitor display by referring to the order when the magnitude of the component is a predetermined value or more.

This change determines the order of treatment and examination after discussion with the patient. After making the decision, pressing the confirm button automatically changes the order of the unit images placed on the screen. Therefore, the rationalization of the examination time can be achieved.
15 is a medical treatment explanation forming means, and, similar to the medical treatment order setting means 14, the dentist fills in the contents that the patient thinks necessary, such as the entry of the medical treatment start time, the urgency of the medical treatment, or the medical treatment technique. Means. This entry is made by inputting from a computer keyboard (for example, FIG. 3 (315)), selecting a default explanation by an operation using a mouse (for example, FIG. 3 (316)), or operating buttons of the intraoral camera shown in FIG. It may be input by operating a button attached to the camera body in a state of being connected to the input interface.
In the medical treatment explanation forming means 15, the medical treatment start date or the scheduled medical treatment start date is entered in 21b to 23b shown in FIGS. 2 (c) to 2 (e). May be.
The shortest possible medical start date is called the planned medical start date entry column in the database of each patient recorded and accumulated by the recording means 17, and is the date that has not been entered, and the shortest date is displayed. You may have the function set up like this.

A specific configuration is shown in FIG. This is a partial configuration of the medical treatment explanation forming unit, and shows a state where the others are omitted. 151 is a patient database calling means, which is a database in which image data, ranking data, treatment start date (including time) data, and explanation data shown in FIG. 2 are recorded, and is generally managed. The related data is recorded in a temporary recording area. This may be configured such that when there is a large amount of accumulated data, the data is called to the database on the trip to be examined.
The shortest medical day search means 152 calls the medical start date data and searches for the date on which the medical start date has not been entered from the search start date. Output as the date of treatment.
Reference numeral 153 denotes a shortest medical care date display means for displaying the date and time detected by searching by the shortest medical care date search means 152 on the display unit on the unit image.

154 is an empty medical treatment date display means for displaying the open medical treatment date in an easy-to-understand manner. For example, an analog clock and calendar abbreviated display, etc. Or you may display by a year unit.
Reference numeral 155 denotes a decision input unit, which is an input unit for starting recording in a database together with patient consent.
Reference numeral 156 denotes a recording unit which is a unit for recording in a database. This recording unit 156 is the same as the recording unit 17 and may be confirmed and recorded by the recording unit 17. Since other doctors may have the same schedule as the patient at the same time, it is preferable to record in the database as soon as it is determined, since rapid eter-based recording is required.

Reference numeral 16 denotes display output means for editing and displaying an image composed of unit images, medical treatment ranks, and medical treatment explanations on a computer monitor display, or on a sheet using a printer (for example, FIG. 3 (317)). The edited image is printed and printed.
Reference numeral 17 denotes a recording means for recording the edited image data, which is recorded as a part of the electronic medical record provided by the dentist, or is stored in the patient's mobile phone or computer via a storage medium. It is a means for recording. The recording means 17 includes a database in which data on the entire patient is accumulated from individual patient data.

Next, an example of the intraoral camera shown in FIG. 3 will be described.
Reference numeral 301 denotes a gripping housing, which is formed in a cylindrical shape so as to form a pencil-shaped intraoral camera. A circuit board, a USB connection circuit for connection with the outside, and a USB socket are inscribed therein. Yes.
A camera unit 309 is integrally connected to the tip. For example, as shown in FIG. 3E, the camera unit 309 has, for example, a CCD camera arranged at the center, and a white LED and other color LEDs around it. The other illumination elements 312 are arranged concentrically at regular intervals.
Reference numeral 302 denotes a reflecting mirror unit. A flat mirror 303 arranged at an angle of 45 degrees, for example, is connected to the tip, and a cylindrical portion 305 is formed at the rear end in a state where it can be inserted and connected to the outer periphery of the camera unit 309 and exchanged. ing. The outer shape of the camera unit 309 and the inner shape of the cylindrical portion 305 of the reflecting mirror unit 302 are preferably formed in an elliptical shape and set so as not to rotate when inserted and mounted.
The reflecting mirror unit 302 can be exchanged at appropriate times. FIG. 3B shows a state in which a reflecting mirror unit equipped with a plane mirror 303 is mounted. FIG. 3C shows a reflecting surface in which a spherical convex mirror 308 is set. The mirror unit 310 is inserted and coupled with the camera unit 309.

As described above, when photographing all teeth, the convex reflection image of the convex mirror 308 is photographed by the camera 313 of the camera unit 309 using the reflector unit 310 connected to the convex mirror 308 of FIG. The output light of the element 312 reflects the convex mirror 308 and irradiates the observation site in the oral cavity. The camera 313 is exemplified by a CCD format, a C-MOS format, and the like, and a higher resolution is preferable for the resolution. However, when a moving image is mainly used, it may be used after being reduced in image.
In the case of normal photographing, the cylindrical portion 305 of the reflecting mirror unit equipped with the plane mirror 303 shown in FIG. 3B is inserted into the outer periphery of the camera unit 309 and used.

Reference numeral 304 denotes a lead wire, and a dedicated electric lead wire, a general-purpose USB cable, or the like can be used.
Reference numerals 306 and 307 denote operation buttons, which are one or a plurality of push buttons, a rotary button, a combination of these buttons, and the like. In this embodiment, two buttons are shown. In addition to operating the camera such as turning the power on and off, the GUI for operating the selection and operation display window displayed on the monitor display 314A of the computer 314 connected via the lead wire 304 by pressing this operation button 307 May have (graphical, user interface) functions.
For example, when the order of unit images is determined, the operation buttons 306 and 307 can be operated and executed when the unit images are automatically rearranged in order.

For example, 306 may be a left click of the mouse, a button corresponding to a function, and 307 may be a button corresponding to a right click.
Reference numeral 314 denotes a computer, which exemplifies a computer integrated with the monitor display 314A. In addition, a combination as a dedicated device may be used.
Reference numeral 315 denotes a keyboard, and 316 denotes a computer mouse. Both are used for computer operation, and also serve as a switch for operating the intraoral camera.
Reference numeral 317 denotes a printer, which is formed by an ink jet method, a laser type color printer, or the like, and is used when a patient's own intraoral image is printed and provided.
The camera configuration shown in FIG. 3 captures an image reflected by a reflecting mirror, so that a clear image is always obtained without being out of focus.

FIG. 3D shows a reflecting mirror unit 318 using a concave mirror 311 as a reflecting mirror, and is used when, for example, an enlarged image is required. In addition, in the case of intraoral, when only the inner side from the dentition is magnified, the curvature of the concave mirror 311 is adjusted in the direction close to the plane mirror, and shoots from a position slightly away from the dentition. In some cases, a wide range of images is acquired.
The present invention handles not only the dentition but also the tongue, lips, gingiva, etc. as a wide range image or unit image.
For example, the present invention can be suitably used when a polyp, which is a manifestation of cancer of the tongue, is displayed as a unit image to explain medical care.

Next, an example for forming a full-tooth image is shown in FIG.
The camera to be used is one using a reflecting mirror unit 302 using a plane mirror 303 as shown in FIG.
The image may be a still digital image or a moving image digital image.
Note that when a plurality of still images are obtained from a moving image digital image, since the number of pixels is relatively small because it is for moving image shooting, it is preferable to shoot a still image while moving it with an auto shutter.
Photographing is performed on all teeth of the lower jaw 600 shown in FIG. 6A while moving the plane mirror 303 of the reflector unit 302 in the direction of 612 from the imaging surface 601. In the case of digital moving image shooting, since it is the same as inputting a still image at about 30 frames / second, the reflector part of the intraoral camera for digital moving image shooting is shown in FIG. 6 (a). If it is moved along the locus 601 to 612, a large number of still images are obtained. In addition, since still image continuous shooting has a larger number of pixels and higher resolution than still image acquisition by moving image shooting, it is a preferable mode when acquiring images of individual teeth from this entire tooth image.

FIG. 6B shows a part of each image when the photographing shown in FIG. 6A is performed. 613 is a common partial image of the images 601 and 602, 614 is a common partial image of the images 602 and 603, and 615 is a common partial image of the images 603 and 604.
In addition, photographing is performed so that common partial images can be obtained in 604 and 605, 605 and 606, 606 and 607, 607 and 608, 608 and 609, 609 and 610, 610 and 611, and 611 and 612, respectively.
In a state where these images are binarized and the contours are acquired, the contours of the common parts are superimposed so as to match between the images. Furthermore, images 605, 606, 607, 608, 609, 610, 611, and 612 are taken and imaged in order, and the respective images are connected on the basis of the common part to obtain a full-tooth image. In addition, this image was taken closer to the teeth, but with some distance, the tongue and lips were captured as an image, and other than the same teeth as when using a convex mirror as a reflector. A wide range image including a part can be formed.

Next, the operation of the embodiment will be described in detail with reference to FIG.
The intraoral image photographing means 11 photographs, for example, all upper teeth in the oral cavity. The position of the captured image is shown in FIG.
The intraoral image photographing means 11 may be any image that includes at least teeth that have been treated by a dentist and that can be understood as to which part of the mouth corresponds.
The image shown in FIG. 2A is, for example, taken by the intraoral photographing unit shown in FIG. 3C, and further calibration may be performed to correct the distortion. Further, the intraoral image photographing means 11 is not necessarily all teeth, but may be a partial tooth or a single tooth. FIG. 2 (a) shows the upper jaw 20, the entire teeth and the hard palate are also photographed, and medical examination of this part may be performed together.

Next, the medical site detection unit 12 automatically or manually extracts a site requiring medical care and improvement. In the case of manual detection, as with the graphic software, use a mouse to specify a circle or square, copy, cut, etc., and paste this by pasting work 20a in FIG. 2 (a), Reference numerals 20b and 20c indicate a state in which a circle of a conspicuous color is manually or automatically indicated on the target tooth by graphic software.
Manual indication display means, for example, drawing a circle, square, or other contour figure etc. that has been transparently processed by operating the mouse and keyboard attached to the computer. For example, when the button is pressed with the mouse on the screen with the pointer on the designated area, a circle with a predetermined radius, a square with a predetermined area, etc., and the inside of which is transparently processed are displayed. .
Next, the unit image forming unit 13 adjusts the designated tooth 20a shown in FIG.

At that time, for example, a rank column 21a for entering the rank after determining the rank of treatment, for example, a medical treatment start date column 21b for filling in after the treatment start is decided, and an explanation column 21c for describing what kind of medical treatment is performed are added. Is set.
This shortest medical treatment date is displayed, for example, in the medical treatment start date column 21b of the unit image with the earliest ranking in FIG. If the patient agrees with this date, the user moves to the decision input means 155 to determine this date and records it in the patient database with the recording means 156.
When the patient does not agree, the empty medical day display means 154 displays the empty medical day in a two-dimensional format such as a calendar format.
For this display, a schedule display method such as a list form or a hand turn form is adopted, but at least a display that is easy to understand for the patient may be used.

Since not only the date but also the time is required, it is preferable that the clock display is also performed. Based on this display, if there is an agreement on the medical treatment start date, the date and time is input by the decision input means 155 and recorded in the database by the recording means 156.
Moving to the next rank unit image, the same medical start date is determined and entered.
Such a schedule operation for a medical treatment date should avoid confusion with a schedule with other patients that did not occur in a temporary medical treatment when the present invention sets a plurality of scheduled medical treatment dates. Therefore, it is effective for clarifying the schedule.
The ID number may be entered in any column for each tooth. This field shows the box display for input used in the database, etc., and the medical date can be automatically determined from the medical schedule of other patients,
When the unit image is displayed, the vacant time may be displayed from the data of other patients.

As for the display contents of these column frames, it suffices if there is at least a column in which the treatment order is displayed in the pre-treatment image, and each tooth may be displayed with an identification code.
FIG. 2D is a unit image 22 showing the medical tooth 20b of FIG. 2A, and FIG. 2E shows the unit image 23 of the medical tooth 20c of FIG. Each is shown.
In the unit image 22, a rank column 22a, a medical treatment start date column 22b, and an explanation column 22c are integrally displayed. Similarly, FIG. 2E also shows a rank column 23a, a medical treatment start date column 23b, and a description in the unit image 23. The column 23c is displayed integrally.
When confirming, the confirm button (including the virtual button displayed on the screen) is pressed. Then, when displaying the image after treatment, it may be displayed first, and after that, it may be rearranged and displayed according to the number in the rank entry field. By automating this work, finally It can shorten the time for preparing the paper to be delivered to the patient.

The figure shown in FIG. 2 may show a state in which the whole is displayed on the monitor display of one computer. In this case, there is a case where the operation range of the display output means 16 is already used.
In the medical treatment order setting means 14, the order of the order column 22a is determined and entered by the dentist alone or while the dentist and the patient discuss. Similarly, the medical treatment explanation forming means 15 fills in the medical treatment start date column 22b and the explanation column 22c. Since this entry includes a lot of technical content, the dentist may make it alone in advance.
The display output means 16 forms and displays a state in which a plurality of unit images determined on the computer screen and all tooth images are posted.
The display output means 16 is preferably displayed on one screen when it is performed during dental treatment.

However, when there are many unit images, scrolling may be performed, the image may be reduced as necessary, or displayed in a thumbnail shape.
Further, the confirmed image in the display output means 16 may be printed on paper by a printer and distributed to the patient. A patient goes to the hospital to execute a menu program for improving the health of the oral cavity by possessing his or her oral cavity as an image, and performs dental care and improvement. After completion of the medical examination, the intraoral imaging is performed again as shown in FIG.
The image display as shown in FIG. 2B is performed by using the teeth 20a of the same part as the unit image 24. Reference numeral 24d denotes a medical site. For example, the medical order setting unit 14 searches for the same image data from image data in which the medical order is set in advance, and the displayed order is displayed.

In 24b, for example, recorded items when medical treatment is performed by the medical treatment explanation forming means 15 are described in advance.
The unit image after medical treatment shown in FIG. 2A is a unit image before medical treatment, which is displayed at a location adjacent to the same, and is used for trust to the dentist and maintenance of the treated tooth. Recognize the timing of hospital visits. 24c is, for example, an explanation column after medical treatment. If it is a prosthesis, the lasting period, and if it is a tooth stain, the next appropriate cleaning date is described. The explanation column for consulting with the patient about the start of the next medical treatment is more preferable. And when starting medical care, a column may be changed into the format of the unit image 21, and order | rank, a medical treatment start date, etc. may be set. In this case, although it may be several years later, it is possible to avoid duplication of treatment dates with other patients by simply putting the date on the start date of medical treatment.
Then, the display output means 16 prints, for example, four images as indicated by 400 in FIG. 4 on a single sheet by a printer and passes it to the patient, giving the patient the necessity of continuous medical care.

In FIG. 2, the intraoral wide-area image shown in FIG. 2 (a) is not posted. However, it is preferable to display the wide-area image and clarify the medical treatment site to obtain a better understanding of the patient. . Note that the medical treatment order and the medical treatment start date and time may be either one. In this case, it is preferable that the order of the unit images represents the medical treatment order, and the unit image display accompanied by at least the medical treatment start date is preferable.
Each of the display columns in FIGS. 2 and 4 is an example, and the number of display columns per unit image and the display contents are also appropriately selected according to the purpose of treatment, the schedule, and the like.

Next, another embodiment will be described with reference to FIG.
Reference numeral 51 denotes a wide-area image input means for photographing all the upper and lower jaw teeth in the oral cavity. For example, all the teeth reflected on the convex mirror shown in FIG. Thus, a wide-range image may be obtained, or a continuous image as shown in FIG. 6 and a common part may be synthesized from still images constituting a digital moving image to form a full-tooth image.
52 is a tooth detection means for extracting image data of each tooth from the dentition obtained by the wide range image input means 51. For the extraction, for example, by using a plane mirror shown in FIG. 3 (b) in addition to means for detecting a closed circle by contour extraction, extracting the periphery of the circle by a predetermined range, and imaging each tooth as a single sheet. However, if the number of pixels of the camera is set to a higher resolution, the means for detecting the unit image from the entire tooth image or the intraoral wide-area image is more reasonable. It is preferable.

Next, the operation of the embodiment shown in FIG. 5 will be described with reference to FIG.
All the teeth are photographed by the wide-area image input means 51 from within the oral cavity of the patient, and image data 700 of all or one tooth is formed (FIG. 7A). The image data 700 indicating all teeth can be an example formed by connecting the still images shown in FIG.
From the wide range image data 700 obtained, a tooth image is formed manually or automatically by the tooth detection means 52.
As a method for automatically detecting teeth, the contours of image data in the oral cavity are extracted and the contours of the teeth are detected.

In this case, when the contour is incomplete, several points are detected and a virtual circle passing through the several points is formed. Since this virtual circle can be regarded as the position of one tooth, the radius is further expanded from the assumed center by a predetermined value, and the range is extracted as a square surface as an image of one tooth.
For example, FIG. 7B shows the extracted image. A tooth image 701 for the tooth 71, a tooth image 702 for the tooth 72, and a tooth image 703 for the tooth 73.
Next, in the unit image forming unit 53, these tooth images are associated with patient information such as identifiers to form unit images (FIG. 7C). In the unit image 74, an extracted tooth image 701 and a display column 704 for entering the medical order and the like are posted.
The unit image 75 includes a tooth image 702 and a display field 705, and the unit image 76 includes a tooth image 703 and a display field 706.

These unit images are recorded and registered in a preset patient database, and a patient's upper / lower intraoral data list can be formed.
The medical image selection means 54 extracts a unit image 77 indicating a tooth image that is a medical treatment or improvement target from among them, visually or automatically (FIG. 7D).
The medical order setting unit 55 and the medical treatment explanation forming unit 56 having the same configuration as in FIG. 1 and performing the same operation, respectively, see the unit tooth image shown on the computer display with the dentist alone or preferably with the patient. While filling in.
Then, at the stage where the medical treatment order is determined and the medical treatment start date and the like are written, the display output unit 57 displays the sequence of unit images arranged in the order as shown in FIG. As shown in FIG. 7 (f), the image may be displayed in an edited state that further includes a wide-range image, and it is possible to form a situation in which the patient is aware of the medical treatment and can obtain consent for the continuous medical treatment. .

The unit images 707, 708, 709, and 710 are preferably arranged in order of rank or order of treatment start. FIG. 7F shows, for example, a screen display including all tooth image data 711 or printed tooth data 79 carried by the patient.
Furthermore, this state can be printed out on a medical record or distribution form, or output to a patient-specific storage terminal such as a mobile phone or a dedicated homepage, so that the patient's awareness of continuous medical care and oral health can be improved only by the patient. In addition, it is possible to raise awareness of the surrounding people and to improve the soundness of dental management. The recording means 58 records these unit images in a database and is used as appropriate for adjusting the schedules of other patients.

Further, another embodiment of the present invention will be described in detail with reference to FIG.
In FIG. 8, a coordinate display grid 802 is superimposed on the intraoral wide area image 801 and displayed.
Reference numeral 800 denotes a medical image display in which an image is printed on one sheet of paper or a medical image display displayed on a computer monitor image.
In the printed state, each unit image is confirmed as a still image.
The horizontal axis 802a is divided into equal intervals, respectively, with symbols a, b, c, d,..., And the vertical axis 802b is also equally divided into equal numbers, 1, 2, 3, respectively. ... is used to identify the location.
Reference numerals 803 to 804 indicate the range surrounded by the vertical axis and the horizontal axis as unit images, and are provided with a medical treatment rank column and a medical treatment explanation column.
803 is a portion of coordinates 4-e (803a) of the intraoral wide area image 801,
Reference numeral 803b denotes a field in which the treatment order, treatment start date, and description are entered and displayed, and 803c is an image within the corresponding coordinates.

Reference numeral 804 denotes an enlarged image of the portion of the intraoral wide-area image 801 at the coordinate 4-e. When the image is taken separately by another camera, an intraoral camera using a concave mirror such as 804a as a reflecting mirror (FIG. 3 (d)) may be specified.
Reference numeral 805 denotes a unit image of the portion 2-e indicated by the coordinates 802, which is formed in the same manner as the unit images 803 and 803.
Each of the corresponding parts is magnified or taken with an intraoral camera using, for example, a plane mirror shown in FIG. 3 (b) as a reflecting mirror, and an intraoral camera using a concave mirror shown in FIG. 3 (d) as a reflecting mirror. Indicated. The camera used is preferably shown with a display such as 804a in FIG.
This is because the intraoral wide-area image 801 is displayed as a still image in one monitor, the unit image 803 is displayed in the vicinity thereof, the image portion 803c is set to the moving image mode, and the intraoral area is shown in FIG. Is taken until the moving image in the screen 803c becomes the coordinate 4-e of the intraoral wide-area image 801, and the corresponding unit image 803 is obtained by pressing the shutter button so as to become a still image at the same timing. Is exemplified. 803d is, for example, a polyp.

As described above, the unit image 804 is taken with the concave mirror 318. It is indicated as 804a to distinguish the display. A unit image 803 shows an enlarged version of a polyp 804b formed on the tongue, and a unit image 804 shows the enlarged state.
In this way, as a means for determining the imaging position in the oral cavity, by forming the coordinate information in the intraoral wide area image, it is possible to easily teach the patient the position of gingivitis, tongue cancer, etc. The enlarged image can be displayed in a more easy-to-understand form in relation to the unit image in which this part is more strongly associated.
In addition, the present invention combines a technique using a concave mirror and a convex mirror shown in FIG. 3 and a technique obtained by combining a still image by moving a reflecting mirror along a dentition when acquiring a wide area image. The image may be formed.

That is, only the dentition is taken as a still image, the part of the tongue is photographed using convex and concave reflectors, and the images are combined to obtain a wide intraoral image with a dentition without distortion. Furthermore, it is also possible to specify the lower part using the deformed coordinates with reference to the dentition as the medical treatment part.
The present invention can also be formed by combining all flat still images.
For example, a dentition image is obtained by the method shown in FIG. 6 and is taken from a slightly higher position using a plane mirror, and includes at least the side of the tooth that can be compared in shape, and the entire intraoral area Is acquired with several images.
Then, the dentition image is compared with other images including the oral cavity.
At that time, a conversion coefficient is obtained from the common tooth size. Other intraoral images are reduced or enlarged based on the conversion coefficient. When the photographing state is inclined, the shape of the distant teeth may be compared to consider the inclination.
By stitching together in this way, an intraoral wide area image with less deformation can be obtained.

  The present invention proposes a dental system that can renew patient's intraoral information by providing the patient with easy-to-see intraoral information in order to achieve oral health in dental practice, It is effectively used in the field of dentistry.
