Definitions
- the present invention relates to a system for photographing the entire oral cavity and displaying it in a panoramic manner.
- Treatment of oral diseases such as dental caries often ends when the intended treatment is completed.
- the treatment of dental caries often begins with the patient being aware of symptoms such as tooth pain, discomfort, etc., and there are many patterns in which the visit ends when 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.
- the oral cavity cannot be generally 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 himself / herself does not know the symptoms that can be done.
- Patent Document 1 shows a configuration of an electronic medical chart that is easy to see from the patient side by displaying all dentitions on a computer monitor and coloring individual teeth. The visibility of the dentition is also a requirement 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. Such a configuration is necessary.

歯列は、咬合平面に対して弓状に湾曲した形状であり、その全体を現実的に把握する場合は、2次元によるパノラマ表示では、個々の歯の様子はわかるが、平面状に歯が並んでいる状態で表示されるため、3次元的な把握は不十分であることから、3次元的に表示できる手法が好ましい。
図16は、本発明の一実施例を示す図である。図中、A10は、反射鏡ユニットであり、硬質のプラスチック製等で形成され、先端に所定の角度(例えば45度)で設置された反射鏡A10Kを設け、後端に撮影ユニットA14の外周と接続可能な円筒状の装着部A10Sが形成され、その間は、開放された形状となっている。
図17は、本発明の一実施例を説明する為に用いられる口腔内カメラの一例であり、一部を断面図として示した。図中、A21は、把持用の筐体であり、内部空間を具えた円柱状を有し、先端にカメラとカメラの周辺に形成された照明用光源とからなる楕円筒状の撮影ユニットA23が筐体A21より突出した状態で接続し、後端に外部表示装置と連結する為のケーブルA26が接続する。
本発明は、実画像を得る際に操作されるスイッチの押す方法を、例えばコンピュータ操作時に行われるダブルクリック手法のような一定時間に押す回数で、実際撮影する迄の時間を調整して、歯科医の治療時、診察時及び患者説明時、カメラ操作の安定化を図ることを可能とする。又、撮影動作タイミングをモニター画像上でカメラのスイッチを操作して表示されるタイミングを示すアイコン的表示(例えば2回で2秒、その後数回連写)を指定して、そのタイミングを決定しても良い。
図21(a)は、本発明の実施例を示すブロック図である。図中、B8011は、X線画像撮影手段であり、X線出力装置と、X線CCDセンサの組み合わせや、X選出力装置とX線蛍光板及びCMOS又はCCDカメラとの組み合わせ、が例示される。具体的には、図21(b)に一例を示した。
本発明は、X線画像と実画像との併設合成によりわかりやすい画像が形成できるが、更に、補綴物の仮想形状や色情報を当該画像に重ね合わせて合成し、治療後の仮想的な状態をわかりやすく表示することを可能とする。
X線画像b201を撮影して形成する。これは、例えば既成のX線パノラマ撮影装置から得られたパノラマ画像や、数本毎に全歯をX線撮影をして画像を取得し、これをデジタル画像に変換した後、それぞれの画像に対し、例えば輪郭抽出後、共通部を検出する。
次いで、本発明の実施例を図24を参照して詳細に説明する。図中、1a01は、小型電池であってボタン型、円筒型、シート型、ピン型等の電池が例示され、また一次電池、二次電池のいずれも使用が可能である。1a02は、昇圧手段であって、DCーDCコンバータ、チョッパー型、その他のスイッチングレギュレータであって、例えば1.5Vを3V前後に昇圧する機能を有するものが使用される。1a03は、制御手段であって、ワンチップタイプのコンピュータ、ASIC等の制御チップが例示される。1a04は、表示手段であって、液晶パネル等で形成される2次元表示可能なものが例示される。
本実施例は、歯科診療について、例えば患者のパノラマ状全歯列画像、治療部位画像をコンピュータのモニター(ディスプレイ)画面に表示すると共に、細分化して形成された動画を目的に応じて結合させて結合動画として再生することにより、患者ごとに治療の説明をする際、わかりやすい説明を可能とするものである。歯科医師は、細分化された動画を予め結合した既成動画列を使用しても良いが、事前に選択し編集結合してもよい。
〔歯肉と歯の境界検出手段〕
本発明は、歯と歯肉の境界を明確に設定検出可能とするための構成を含む。
12 診療部位検出手段
13 単位画像形成手段
14 診療順位設定手段
15 診療説明形成手段
16 表示出力手段
