That is, in the case of panoramic photographing in which the rotating member 400 is rotated, the source (440) emitting X-rays and the source (440) are disposed to face the emitted X-rays. A pano sensor 480 for detecting is installed on one side and the other side of the rotating member 400, respectively, and rotates together with the rotating member 400 to perform panorama photography (see FIG. 1).

In addition, in the case of a cephalograph that is performed while the rotating member 400 is fixed, the pano sensor 480 moves sideways so as not to block an X-ray radiation path emitted from the source 440. Cephalo-Sensor 540 is disposed so as to face the source 440 in one direction in which the rotating member 400 stops and detects X-rays emitted from the source 440. This is done (see Figure 2). Here, 'Cephalo' is an abbreviation of Cephalometic, that is, two measurements, and the description of the cephalographing and the panoramic photographing are as described above in the background art.

At this time, the direction in which the rotating member 400 is stopped for cephalographing is the support member 300 and the rotating member 400 are arranged side by side and the source of the pano sensor 480 and the source 440 ( It is preferable that the 440 is set to be disposed at a position close to the first column 200, which will be described later. In this state, the cephalo sensor 540 is disposed to face the source 440.

A diagram of an X-ray imaging apparatus including a follower sensor and a pano sensor.

As shown in FIGS. 3 and 4, the X-ray imaging apparatus including the cephalo sensor and the pano sensor according to the present invention includes a first column 200, a support member 300, a rotation member 400, and a source 440. ), The pano sensor 480, the second column 500 and the cephalo sensor 540. At this time, it may further include a base 100 of the plate shape is mounted on the ground on which the first column 200 and the second column 500 are installed.

The base 100 is seated on the ground so that the first column 200 and the second column 500, etc. are installed, and a chair (not shown) is located where the photographed person (not shown) is positioned for X-ray imaging. It may be installed further.

In this case, the base 100 is not an essential configuration, and the first column 200 and the second column 500 may be directly installed on the floor of a building.

The support member 300 is installed such that one side thereof is coupled to the first column 200 and extends to a photographic side positioned for X-ray imaging. That is, the photographed person is positioned below the support member 300.

The rotating member 400 is coupled to the lower portion of the support member 300 to be rotatable. At this time, the rotation member 400 and the support member 300 is coupled by the rotation shaft 320, one side of the rotation shaft 320 is installed to be rotatable under the support member 300 and the other side is the rotation member 400 is fixedly coupled.

Shall be.

The source 440 is coupled to one lower side of the rotating member 400 as a means for emitting X-rays.

The pano sensor 480 is a sensor used when the rotating member 400 rotates with respect to the photographic subject of the X-ray photographing and performs the panoramic photographing to perform the X-ray photographing.

The pano sensor 480 is installed on the lower side of the other side of the rotating member 400 to face the source 440 so as to detect X-rays emitted from the source 440.

That is, the source 440 and the pano sensor 480 are respectively installed on one side and the other bottom of the rotating member 400 to face each other, the source 440 and the pano with the rotation of the rotating member 400. The X-ray panoramic photographing is performed while rotating about the photographic subject positioned in the lower center of the sensor 480.

The second column 500 is equipped with a cephalo sensor 540 used for X-ray cephalo imaging, which is performed while the rotating member 400 is stopped.

The sensor 480 is installed to be located.

Since X-ray cephalographing is performed after fixing the rotating member 400 differently from panoramic photographing, the installation position of the second column 500 may be determined according to the fixing position of the rotating member 400. However, the fixing of the rotating member 400 for sephalographing is preferably fixed in a direction parallel to the support member 300, and the second column 500 also extends to an extension line of the support member 300. It is desirable to install. However, it is obvious that the fixing direction of the rotating member 400 for X-ray cephalographing may be variously determined and the installation position of the second column 500 may also be variously determined correspondingly.

In a state where the rotating member 400 is stopped for X-ray cephalographing, the source 440, the photographed person, the pano sensor 480, and the cephalo sensor 540 are arranged in a straight line. Therefore, the pano sensor 480 blocks the path of the X-rays emitted from the source 440, so that the pano sensor 480 is out of the path of the X-rays emitted from the source 440 when the X-ray cephale is photographed. You need to move it.

In order to move the position of the pano sensor 480 for the X-ray cephalographing, a horizontal rail 450 is installed at the lower side of the other side of the rotating member 400, and the pano sensor 480 is the horizontal rail ( 450 is installed to move along.

By moving in the left or right direction along the transverse rail 450 may be automatically adjusted to be positioned in a position away from the movement path of the X-rays emitted from the source 440. Therefore, X-ray panorama shooting and cephalographing can be performed at once without any manipulation or position shift.

The position of the source 440 may also be configured to slide in the vertical direction as in the case where the pano sensor 480 slides in the vertical direction along the first longitudinal rail 460.
