Description

本発明はＸ線撮影方法および装置に係り、特に歯科用の回転パノラマ撮影方法および装置に関するものである。   The present invention relates to an X-ray imaging method and apparatus, and more particularly to a dental rotational panoramic imaging method and apparatus.

歯科用パノラマ撮影は歯および顎骨とその周辺領域を1枚のＸ線写真に写し出すことを可能にした。又、パノラマ撮影はアナログ撮影からデジタル撮影へと移行してきている。   Dental panoramic photography made it possible to project teeth and jawbones and their surrounding areas into a single X-ray photograph. In addition, panoramic photography has shifted from analog photography to digital photography.

従来のデジタルパノラマ撮影系は、撮像装置として、通常フルフレームトランスファー型のCCDセンサを用いており、このCCDセンサによれば、CCDセンサに蓄積部を有していないため、撮影データは、一方向にしかデータ送りすることができなかった。即ち、右回転撮影ならば、撮影データのデータ送りは、右回転しかできない、と云う欠点があった（技術資料、SD-25、FET-CCDエリアイメージセンサの特性と使い方（非特許文献１）参照）。   The conventional digital panoramic imaging system normally uses a full frame transfer type CCD sensor as an imaging device, and according to this CCD sensor, the CCD sensor does not have a storage unit, so the shooting data is unidirectional. It was only possible to send data. In other words, in the case of right-rotating shooting, there was a drawback that the data transfer of shooting data could only be rotated to the right (Technical data, SD-25, FET-CCD area image sensor characteristics and usage (Non-patent Document 1)). reference).

又、従来のパノラマ撮影機構は、特許第３８８０１１８号公報（特許文献１）に記載されているように、
「Ｘ線ヘッド‐回転中心‐被写体‐Ｘ線撮像手段」
の構成となっており、被写体上をＸ線ビームがスキャンしていく方向とＸ線撮像手段上に投影像が動く方向とが同一方向であった。
特許第３８８０１１８号公報 技術資料、SD-25、「FET-CCDエリアイメージセンサの特性と使い方」浜松ホトニクス株式会社、平成14年4月 Moreover, as described in Japanese Patent No. 3880118 (Patent Document 1), the conventional panoramic photographing mechanism is as follows.
"X-ray head-center of rotation-subject-X-ray imaging means"
The direction in which the X-ray beam scans over the subject and the direction in which the projected image moves on the X-ray imaging means are the same direction.

It is assumed that frame images can be acquired.

ここに云う「パノラマ撮影像」とは、「ある断層を連続的に撮影することによって得られた断層撮影像」を意味するものとする。   The “panoramic image” referred to here means a “tomographic image obtained by continuously photographing a certain tomographic image”.

１．従来のＸ線撮影の幾何学的配置に比べ、本発明の幾何学的配置でのＸ線撮影では拡大率が大きくなるため解像力が向上した画像を呈することができる。
2．1回の撮影で、同じ部位をＸ線ビームが２回スキャン可能な部位では２枚の撮影像を生成することが可能となり、この2枚の画像より、診断がより確実となる。（これは、２枚の撮影像で異なった方向からの撮影ができることによるものである。）
3．フレーム画像を使用するので、重ね合わせを変化させることにより、任意の曲面パノラマ撮影像を合成し、抽出することができる。 1. Compared with the conventional X-ray imaging geometric arrangement, the X-ray imaging with the geometric arrangement of the present invention can provide an image with improved resolving power because the enlargement ratio is increased.
2. It is possible to generate two radiographed images at a site where the X-ray beam can be scanned twice by the same imaging, and diagnosis is more reliable than these two images. (This is due to the fact that two shot images can be taken from different directions.)
3． Since a frame image is used, an arbitrary curved panoramic image can be synthesized and extracted by changing the overlay.

上述したように、従来のデジタルパノラマ撮影系は、「Ｘ線ヘッド‐回転中心‐被写体‐Ｘ線撮像手段」の構成を取っており、被写体上をＸ線ビームがスキャンしていく方向とＸ線撮像手段上に投影像が動く方向とが同一方向であった（図1参照）。従って、実際のパノラマ撮影は図3に示すように行なわれている。
しかし、本発明によれば、デジタルパノラマ撮影系は、「Ｘ線ヘッド‐被写体‐回転中心‐Ｘ線撮像手段」の構成を採用し、しかも、Ｘ線撮像手段である像検出器としてCMOSタイプ等のフレーム画像が取得できるセンサを用いている（図2参照）。従って、実際のパノラマ撮影は図４に示すように行なっている。 As described above, the conventional digital panoramic imaging system has the configuration of “X-ray head-rotation center-subject-X-ray imaging means”, and the direction in which the X-ray beam scans on the subject and the X-ray. The direction in which the projected image moves on the imaging means is the same direction (see FIG. 1). Therefore, actual panoramic photography is performed as shown in FIG.
However, according to the present invention, the digital panoramic imaging system adopts the configuration of “X-ray head-subject-rotation center-X-ray imaging means”, and CMOS type or the like as an image detector that is an X-ray imaging means. A sensor that can acquire the frame image is used (see Fig. 2). Therefore, actual panoramic photography is performed as shown in FIG.

斯様に、本発明によれば、パノラマ撮影によって従来のパノラマ撮影像と逆配置パノラマ撮影像とを、1回の撮影で得ることができる。   As described above, according to the present invention, a conventional panoramic image and a reversely arranged panoramic image can be obtained by one shooting by panoramic shooting.

Ａ．パノラマ撮影による断層像：
1．本発明の図４は左半部の図となっているが、実際には、右半部も撮影が可能であり、通常のパノラマ撮影のように、240度の回転撮影を行なえるため、容易にパノラマ撮影像を得ることができる。
２．ただし、従来のパノラマ撮影と逆配置パノラマ撮影像を1回の撮影で得るためには、回転中心を図４に示すようにスライド移動させることが必要となる。この時、回転中心の移動量はパノラマ撮影像を得ようとする任意の位置によって変化する。
3．パノラマ撮影後に大容量フレーム画像記憶手段に記憶されているフレーム画像を利用して従来のパノラマ撮影像と逆配置パノラマ撮影像を得ることが可能である。 A. Tomographic image by panoramic photography:
1． Although FIG. 4 of the present invention is a diagram of the left half part, in fact, the right half part can also be photographed, and it can be rotated 240 degrees like normal panoramic photography, so it is easy. A panoramic image can be obtained.
2. However, in order to obtain a panoramic image that is opposite to the conventional panoramic photographing in one photographing, it is necessary to slide the rotation center as shown in FIG. At this time, the amount of movement of the rotation center varies depending on an arbitrary position where a panoramic image is to be obtained.
3． It is possible to obtain a panorama photograph image reverse to the conventional panorama photograph image by using the frame image stored in the large-capacity frame image storage means after the panorama photograph.

顎関節撮影（TMJ（Temporomandibular joint）撮影）の場合には、前額断での画像と矢状断での画像を同時に撮影することができる。   In the case of temporomandibular joint photography (TMJ (Temporomandibular joint) photography), it is possible to take images with a forehead and a sagittal view at the same time.

Ｂ. 顎関節撮影（TMJ撮影）による断層像：
１．上記のように従来のパノラマ撮影像と逆配置パノラマ撮影像のような両方の画像を得ることも可能であるが、単独で顎関節用として撮影（TMJ撮影）することも、可能である。
このTMJ撮影の場合には、Ｘ線撮影後に形成するフレーム画像のフレームの重ね合わせを左右同時に可逆的に行なうことにより、前額断での画像および矢状断での画像の撮影像が同時に得られる。 B. Tomographic images by TMJ imaging (TMJ imaging):
1. As described above, it is possible to obtain both images such as a conventional panoramic image and a reversely arranged panoramic image, but it is also possible to shoot alone for TMJ (TMJ imaging).
In the case of TMJ imaging, the frame images formed after X-ray imaging are reversibly overlapped on the left and right at the same time, so that a front-cut image and a sagittal image can be obtained simultaneously. It is done.

即ち、図6に示すように、アームの回転方向を右回転とする撮影でフレーム画像を大容量フレーム画像記憶手段に記憶し、前額断での画像では、画像処理手段において、大容量フレーム画像記憶手段に記憶されたフレーム画像の重ね合わせを例えば、左方向にフレーム画像を重ね合わせ、矢状断での画像では、右方向にフレーム画像を重ね合わせることにより、一度の撮影によって前額断での画像の撮影像と矢状断での画像の撮影像とを同時に得ることができる。   That is, as shown in FIG. 6, the frame image is stored in the large-capacity frame image storage means by shooting with the rotation direction of the arm to the right, and in the case of the image at the front frame, the image processing means stores the large-capacity frame image. For example, when the frame images stored in the storage unit are overlapped in the left direction, the frame images are overlapped in the right direction.
